Easy Peanut Butter Cookie Pie

This is the fastest and easiest pie I’ve ever made. And the only one with peanut butter incorporated three ways.

Except it’s not really a pie at all. I used my recipe for peanut butter blondies and baked it into pie dish, but not before topping with mini peanut butter cups and Peanut Butter M&M’s. It’s my annual contribution to National Peanut Butter Day, which was January 24.

The pie turned out to be one of my favorite blondies recipes ever. According to my WordPress tags, I’ve tagged 29 recipes as blondies. Okay then, I’ve made more than a couple versions, but the base always starts out the same.

One stick of melted butter, 1 egg, 1 cup brown sugar, 1 tablespoon vanilla, with 1 cup flour stirred in. Truly a 5-minute batter. No-mixer, nothing complicated, or fussy. The opposite of what making a real pie tends to be.

The interior is squishy soft and supremely moist, while the edges are chewier with a slight crispiness. There’s no baking powder or baking soda in my blondies because I like them really dense and not at all cakey.

The peanut butter flavor is bold and pronounced, something you’d expect with as much peanut butter as there is packed into this pie.

The brightly colored M&M’s draw me in initially, but it’s the baked-in peanut butter cups that steal the show. I can’t resist peanut butter cups and they add texture to the buttery soft dough, as well as just enough chocolate to satisfy my chocolate + peanut butter cravings.

The pie would make a great base to top with ice cream or even as a fun ‘birthday cake’ for kids, and so much easier than cake since you don’t have to cream any ingredients or frost it.

Over the years of blogging and writing a cookbook devoted to peanut butter,  I’ve combined peanut butter, chocolate, and candy in almost every imaginable combination and permutation, but never as a cookie pie.

Glad I  can check that off my list now.

What’s in Peanut Butter Cookie Pie? 

To make this peanut butter cup cookie pie, you’ll need: 

  • Unsalted butter
  • Egg
  • Light brown sugar
  • Vanilla extract
  • Creamy peanut butter
  • All-purpose flour
  • Salt
  • Mini peanut butter cups
  • Peanut butter M&M’s

How to Make a Giant Cookie Pie

This cookie cake pie comes together much like a regular batch of cookies would! Whisk together the melted butter, egg, brown sugar, peanut butter, and vanilla.

Add the dry ingredients and stir until just combined. 

Turn the cookie dough into a greased pie plate, then insert the peanut butter cups into the batter, pushing them down so the top is almost flush with the surface of the dough. Insert the M&M’s next. 

Then, it’s just a matter of baking the cookie cake pie until done!

Can I Use Natural Peanut Butter? 

No, natural and homemade peanut butters are often too runny and too oily for baked goods. I recommend using a ‘classic’ peanut butter brand like Jif or Skippy. 

Can I Use Chunky Peanut Butter? 

I personally prefer the consistency of creamy peanut butter in my baked goods, but you’re welcome to use chunky peanut butter if desired.

How to Store Peanut Butter Cookie Pie

This cookie cake pie will keep airtight at room temperature for up to 1 week, or in the freezer for up to 6 months. Note that the color may leech from the M&M’s if you freeze it.

How to Reheat Cookie Pie

If you want to reheat leftover cookie pie to make it nice and gooey again, I recommend gently heating the portion you’re going to consume in the microwave in 10-second intervals. Don’t reheat portions you’re not going to consume because then it will get hard.

However, this peanut butter cookie pie is so soft naturally, we enjoy it at room temperature.

Tips for Making Peanut Butter Cookie Pie

If you don’t have peanut butter cups or Peanut M&M’s on hand, use what you do have. Chopped Twix, Snickers, Rolos, plain M&Ms, it’s all good.

Use the recipe as an excuse to clean out your pantry of random candy and half-opened bags of baking chips. If you wait until after Valentine’s to make it, you can clean out all those Valentine’s exchange candy remnants. You’ll have your pantry widdled down just in time for the Easter Bunny, who brings more candy.

For optimal results, cool this cookie pie overnight because it gives the flavors a chance to marry and the pie to really set up fully.

This fast and easy cookie pie has peanut butter worked in three different ways. If you're a peanut butter lover, this pie is for you!

Prep Time 5 minutes
Cook Time 26 minutes
Additional Time 29 minutes
Total Time 1 hour


  • 1/2 cup unsalted butter (1 stick), melted
  • 1 large egg
  • 1 cup light brown sugar, packed
  • 1 tablespoon vanilla extract
  • heaping 1/3 cup creamy peanut butter
  • 1 cup all-purpose flour
  • pinch salt, optional and to taste
  • 12 to 14 mini peanut butter cups
  • about 2/3 cup Peanut Butter M&Ms (I used one 2.83-ounce ‘King Size’ bag sold; optionally substitute with Peanut or Plain M&Ms)


  1. Preheat oven to 350F. Spray a 9-inch pie dish with floured cooking spray; set aside.
  2. In a large, microwave-safe bowl melt the butter, about 1 minute on high power.
  3. Wait momentarily before adding the egg so you don’t scramble it. Add the egg, brown sugar, peanut butter, vanilla, and whisk until smooth.
  4. Add the flour, optional salt, and stir until just combined; don’t overmix.
  5. Turn batter out into prepared pie dish, smoothing the top lightly with a spatula.
  6. Evenly insert the peanut butter cups into the batter, pushing them down so the top is almost flush with the surface of the dough.
  7. Evenly insert the M&Ms into the batter, pushing them down to anchor.
  8. Bake for about 28 to 30 minutes, or until a toothpick inserted in the center comes out mostly clean, or with a few moist crumbs, but no batter.  If your pie has risen in the center, it will deflate as it cools.
  9. Allow pie to cool in pan for at least 30 minutes before slicing and serving; however, for optimal results, cool overnight because it gives the flavors a chance to marry and the pie to really set up fully.


Pie will keep airtight at room temperature for up to 1 week, or in the freezer for up to 6 months (color may leech from the M&Ms if you freeze it).

  1. We made this tonight – used Reese’s pieces instead of peanut butter m&m’s. It is very good but extremely sweet. The texture is so soft and delicious.

  2. Omg I made this for my husband’s birthday and he LOVED it. I called my brothers over and they ate the entire pie. I’m making this again today. So delicious!!! Thank you for sharing.

    1. Thanks for the 5 star review and I’m glad it was a big hit for your husband’s bday! Glad you’re making it again today!

  3. My hubby is gluten free so I substituted the flour for Bob’s Red Mill 1:1 GF flour. It turned out amazing!!!! This is my new new go-to for my hubbys birthday “cake”. ( we aren’t big cake people, so we always try to come up with different things for each others birthdays).

  4. Today I made this with the kids who I watch. This was a great last week of summer treat for them. It was easy for them to help with all of the ingredients and stirring. We used whatever candy they had acquired and left over from other projects in addition to peanut butter cups! The only difference was that we halved the amount of sugar due to all the extra chocolate candy that got placed into the awesome peanut butter base at the end. :) This recipe was definitely delicious, fun, and very kid-friendly!

    1. Thanks for trying the recipe and I’m glad it came out great for you! It’s a great candy cleanout recipe and sounds like you were able to make use of what you had on hand!

  5. This is my new favorite go-to “pie” recipe. I’ll probably make it for every holiday from here on. I accidentally used a full cup of peanut butter once, and found I actually preferred it that way. If you love a peanut buttery taste, I recommend trying it. It gave it a smoother texture, too.

    1. I can see where a full cup would be wonderful :) Glad you’re loving the pie and are a true PB fan like me!!

  6. you’re the best baker i know. ive never been so impressed by someone in my life! seriously its just amazing what you create

    1. You are just tooooooo sweet, Kelsey! Thank you for the kind words and for the YEARS of support. You’re the best! xoxo

  7. I made this pie 4 times over the holidays – once for Christmas Eve, once for New Year’s Day, and twice more as gifts for a friend and godmother. The reviews from all are that it is extremely delicious! I must say that I am not the biggest fan of peanut butter, but this recipe changes all that. It is so moist and tasty, and I can’t wait to start baking all of the other recipes from averie cooks. So glad I found you!!!!

  8. Hi- I am hoping to make this for a holiday bazaar fundraiser. Can I use a throw-away pie dish instead of a glass pie dish? Many thanks –

    1. You definitely can do it in a disposable. Sometimes they run a little skimpy so buy at least a 9-inch! You’re so nice to make this as a fundraiser!

  9. Wow! The peanut butter chocolate chunk cookies were a big hit in my family! i brought them over for thanks giving. Everyone wanted seconds!

  10. Oh my gosh. This was delicious! !! So happy I gave it a try! Posted a pic to my FB wall and got more ‘likes’ and comments than you could shake a stick at!! (Posted a link to your blog too, for all my baker pals)

    1. Thanks for trying it and glad that everyone is loving it – this is one of my most popular recipes! People seem to love this – both the pics and the taste and ease of the pie! Glad you’re a fan too :)

  11. Since I’m a chocoholic I’m not usually a fan of blondies but the peanut butter won me over. I bought a dollar bag of reese’s cups and a theatre box of reese’s pieces at the dollar store (there is NEVER leftover chocolate in our house lol) and only needed 1/2 to half the box. I was going to try to post a pic because I did mine all symmetrical :)

  12. I’ve now made this 5 times in the past 2 months. 3 times for treats at work, people literally fight over the last bite! And I love it because it’s one of the easiest things I’ve ever made! I figure I’ll have the recipe memorized before long!

    1. 5 times in 2 months…that’s awesome! And so glad to hear people literally fight over the last bite and that it’s easy for you to whip up – love hearing things like this!

  13. Can,this be adapted to a 9×13 pan? Id l9ve to make this for my daughter’s birthday party but 8 servings just isnt enough!

  14. I did this pie for my brother’s 22nd birthday (I tought this would be perfect, since He always dreamed about a gigantic cookie). Huge success! I just switched the pb cups (not available in Brazil) for twix and pb twix. Thank You so much for another lovely recipe!

    1. Sorry you don’t have pb cups there! But twix and pb twix sound awesome – they’re a couple of my favorites! And happy bday to your bro – he’s a lucky guy to have you baking for him :) Glad you guys loved this!

  15. Can this be doubled and baked in a 9×13? I need something for a large group; and this sounds amazing and looks really cute.

    1. I haven’t tried in a 9×13 pan. If you need more, I would suggest just making 2 in 2 separate pie dishes. Part of the appeal I think is the circular shape.

  16. So luscious & inviting – Would love to see this submitted to so I can share with all my foodie friends :)

  17. I made this for a Super Bowl party tonight and it was gone before the game ended! Everyone loved it and the presentation is so cute and fun. Thanks for yet another yummy recipe! Love your cookbook as well :)

  18. This looks DIVINE!!! Seriously, I think my hubby would die and go to heaven if I made this for him! Thx for the recipe. :)

  19. This looks amazing. Do you (or any of your readers) think this would be okay as-is made at high altitude, or would you suggest any tweaks?

    1. Because I live in San Diego (sea-level), I have no experience at all with altitude baking so can’t speak to that or give any advice. Sorry!

  20. *jaw drops*

    so…much…peanut butteryyy GOODNESSS!! This is a pie that will make you drop dead from the sheer awesomeness of it!

  21. Blondie Brownies are awesome, add in reeses cups and they become amazing! Love this recipe Averie!

  22. I would be so happily drowning in peanut butter eating this beauty. Loooove cookie pies and reese’s and peanut butter m&ms so this is a major win. Pinned!

  23. Cookie pies are on my list of things to try. A peanut butter version is perfect! This looks so chewy and dense – just how I like my blondies too.

  24. Such a great idea to use a blondie like a pie, I would happily slip into a peanut butter coma while consuming this. Looks so good :D

  25. Hi Averie, I’ve never commented before but have made a few of your recipes. I am in trouble when I do because I want to eat ALL of it:) Just wanted to say thank you. I love your photography style. This may sound strange but I also love your cutting board…very rustic and complimentary to all of your yummy looking goodies!

    1. Thanks for trying many of my recipes and finally saying hi! I am glad you love this board – me too! I bought it about 2 years ago. It’s from the 1860s and was a dough board that I sourced from rural Pennsylvania. Probably an old Amish woman’s. I paid a small fortune for it but I truly love it :) I shot a ton, ton, ton of my recipes for my blog and cookbook on it in 2012-13 and tried to stop using it as much in the past 6 mos but for this post I thought it would be perfect :)

    1. Did you read step 3. of the directions from the blog post? It goes in right there.

      I’m sure you figured that out by now if you already made them and hopefully are enjoying them!

  26. I know this question is bound to be met with some flack, seeing as how most of this entire blog is dedicated to the deliciousness of peanut butter, but how would I go about cutting down the amount of peanut butter used in the recipe? (I know, I know!) This looks amazing and I really want to make it, but I have some non-peanut butter-lovers in my life. I think I can get away with the cups, use plain m&ms and maybe a portion of the creamy peanut butter, but what would you suggest to substitute?

    1. If you don’t like PB or have people who don’t, I wouldn’t make a recipe with ‘Triple PB’ as the title :) I would find a different recipe. There are lots of other blondies recipes that are based on similar principles, most without as much PB. I would start with one of those. There are 29 to choose from!

  27. When I was in England last I was craving blondies but didn’t have a square pan so used a pie dish and well, nothing is like a cookie pie/cake. Devoured the whole thing all too quickly! The pb cups in your pie look gorgeous, I am so fussy with resses pb cups ( I taste good and bad ones some people think they all taste the same but not me #issues ) so seeing them look soooo good in your pie is making me want to go get some right now!!

    1. I totally know what you mean. I think they are made in different plants, factories, etc. and you never know what you’re going to get until you open the bag!

  28. I just love that you baked the blonde in a pie dish! The pb cups and colorful M&M’s are just the perfect way to jazz up the top too! Girl, this is down right fabulous! Pinned :-)

  29. I used to beg my mom for a cookie cake for my birthday. From the Great Cookie Co at the mall….YUM.

    This looks so fun!

    1. the Great Cookie Co (omg!!! haven’t thought about that place in a couple decades!)

      They had one at a mall I used to go to (super small town) and the mall was literally too small for a Mrs Field’s so they had that instead! The memories and I know EXACTLY what you’re talking about!

  30. Right now I have a triple peanut butter cookie pie sitting on my cooling rack! I wanted to bake today but was feeling so lazy, so I grabbed my iPad to read Averie Cooks, and low and behold a super easy pie! Even a laze ball could make!! I followed the recipe to a T, but did not hold out for the 30 minute cooling time, because remember I’m lazy today and waiting 30 more minutes wasn’t in my cards. I grabbed a fork and dove in, and I’m so glad I did, because this is such an easy fix for someone wanting baked goods but lacking in the energy department ;) the taste is YUMMY with a Capitol Y!! I took 2-3 bites and can now feel happy and satisfied enough to let the cooling process commence, thanks Averie! You made my day!

    1. I noticed it didn’t say to add the peanut butter too, but I assumed it would be added when the vanilla and such was added, and mine turned out super delicious!

      1. Thanks for the catch, I updated the recipe. And you were correct. And so glad you tried it the same day I posted it! WOW…awesome! :)

  31. I knew you wouldn’t let National Peanut Butter Day go by unnoticed, Averie! And WOW – this pie looks amazing! Quick and no need to frost? Perfection. :)

  32. I am heading into the kitchen now. I just found a hidden stash of peanut butter cups the other day and now I know just what I am going to use them for.

  33. I love all the candy on top–they look like fun, yummy polka dots!! A quick PB blondie in a pie shape is so perfect. The photo of the fork with that gooey, peanut buttery-melty-chocolaty piece looks especially good! This is a great nod to National PB Day.

  34. Happy belated national peanut butter day!! I agree with Dorothy, this is the best pie ever!! Love all the fun colors!

  35. Step aside all cakes, pies, and regular cookies! You have been demoted!
    Wow, this cake is gorgeous (love how you can see all the different candies) creative, and packed with peanut butter (and that is always a good thing!) What more do you need?!

  36. I love the look of this pie! Er, cookie. I mean, cookie pie! Seriously. Love. Simple yet amazingly delicious recipes like this are the best!!!

  37. Yesterday, I posted a peanut butter recipe on my blog on National Peanut Butter Day. It was not on purpose. I didn’t even know it was Peanut Butter’s big day. I figured it was a total fluke when someone pointed it out, but upon reflection, I think Peanut Butter was speaking to me. Like this pie. This pie is saying: please shove me into your face. And I’m saying: sounds good to me!

    1. It’s weird b/c 2 yrs ago I got the final word come down the pike from my publisher that they were going to publish PB Comfort! On Natl PB Day. How bout those odds!

  38. Looks delish! I loving baking my cookie/blondie recipes into pie form! Best one I converted recently was my oatmeal raisin chocolate chip into a cookie pie. Oh the texture. I don’t think I have peanut butter m&m’s in the house but I do have Reeses Pieces – I bet they would work well in here too
