Soft and Chewy Peanut Butter Oatmeal White Chocolate Cookies

It’s no secret that I love peanut butter and in baking there’s something magical about adding peanut butter to recipes.

It just makes things better.

It makes baked goods moist, rich, and decadent in a going-to-stuff-my-face kind of way.

For the peanut butter allergy folks, you could most definitely use sunflower seed, almond, or cashew butter in these cookies.

I also adore oatmeal cookies.

Did you see my last cookie creation?  Chewy, brown sugary oatmeal raisin cookies

When they are done right, I think that oatmeal-based cookies trump most other cookies.

Today’s cookies have oatmeal in them even though they don’t have much of an “oatmeal cookie taste”.

The peanut butter flavor is more dominant than oatmeal flavor.

When it comes down to it, though, I’ve really never met a cookie I didn’t like.  Oatmeal raisin, peanut butter, chocolate chip, snickerdoodle, molasses.  They’re all good.

Except dry cookies.  Those are not so good.  Don’t break any baking rules and make them dry or overcooked.  Or put nuts into baked goods.  Blech.

So when I saw Jo-Anna of A Pretty Life in the Suburbs’ recipe for Cookies ‘n Creme Stuffed Oatmeal Cookies, she got my wheels turning for this month’s Secret Recipe Club recipe reveal, and it steered me in the direction of using oatmeal.

I’ve also been eyeing the Cooks Illustrated Perfect Chocolate Chip Cookie recipe that I’ve read rave reviews about.  Ever since 2009.  I based last week’s oatmeal raisin cookies from the melted butter technique they used.

Because really, you can do no wrong with melted butter and peanut butter combined with oatmeal and white chocolate.

At least not in my book.

I loved these cookies

And now it’s time to geek out with food science trivia which likely explains why I loved them.

It has to do with sugar ratios, melted butter, and eggs.

The Cooks Illustrated website compared their ‘new cookie’ (2009) vs. the classic Nestle Tollhouse cookie (1950s I’m guessing) in this little chart (source)

Sugar: by having a higher proportion of brown sugar to white sugar, you will get a chewier cookie.  That’s a big bonus for me.

  • TOLL HOUSE RECIPE: Equal Amounts Brown and White SugarA 1-1 ratio of brown to white sugar creates a cookie that’s neither crisp nor chewy.
  • OUR RECIPE: More Brown Sugar Using more brown sugar than white makes for a chewier cookie.


Butter: By melting the butter you get a chewier cookie, less of a cakey cookie, and enhanced flavor.  Yes please.

  • TOLL HOUSE RECIPE: Creamed Solid Butter.  Creaming butter creates a cakier texture in cookies.
  • OUR RECIPE: Browned, Melted Butter.  Melting butter contributes to chewiness; browning it enhances flavor.

Eggs: Reducing egg whites increases chewiness and reduces dryness.  Score.

  • TOLL HOUSE RECIPE: 2 Whole Eggs. Whole eggs contribute to a drier texture.
  • OUR RECIPE: 1 Whole Egg, 1 Yolk. Eliminating one egg white also boosts chewiness.


Take that, Alton Brown.  You’re not the only one who can geek out.

Another thing I loved about these cookies was that I didn’t have to use an electric mixer.

I did everything by hand and with one spoon.   That’s the beauty of the microwave melted butter technique.  You don’t need to whip or cream anything together.  Just melt ‘n stir.

I am still pining away for that Kitchen Aid but so far the Mixer Fairy hasn’t paid me a visit yet.

Not being bothered to use any sort of mixer in this recipe was a nice bonus.

It’s nice having fewer dishes to do.  Beaters, bowls, paddles.  It all adds up.  I hate doing dishes and do everything in my power to keep them to an absolute minimum.

I’d rather spend my time baking and cooking or sampling the raw dough eating the finished product than doing dishes.

And between me, Scott, and Little Miss Cookie Monster, we made quick work on these

Just typing this post and looking at these pictures makes me really want another one.  Or three.

They are chewy, sweet, rich, and the peanut butter flavor is enhanced even more by the addition of peanut butter chips.  I bet butterscotch chips would also be excellent in these, too.

The oatmeal makes them soft

And the white chocolate chips make them sweet

This wouldn’t be an “Averie dessert” if there wasn’t peanut butter in the recipe or white chocolate.  <– Those two links showcase all my peanut butter recipes and all my white chocolate recipes in one place.  I will be adding these cookies to both sections.

Have I convinced you to make these yet?

They’re a new favorite of mine.

They’ve earned a special place in my heart.

And in my stomach.

Soft and Chewy Peanut Butter Oatmeal White Chocolate Cookies - Combining 3 favorite cookies into one so you don't have to choose which to make! Easy, no-mixer dough!

Soft and Chewy Peanut Butter Oatmeal White Chocolate Cookies

Combining 3 favorite kinds of cookies into one so you don’t have to choose which to make – peanut butter, oatmeal, or white chocolate. Soft and chewy, with just enough texture from the oats and plenty of white chocolate in every bite. Fast, easy, no-mixer required recipe. One of my favorite cookies of all time!

5 / 5 ()
Did you make this recipe?


1/2 c unsalted butter

1/3 c creamy peanut butter

1 c light brown sugar, packed

1/2 c granulated sugar

1 egg + 1 yolk

2 tsp vanilla extract

1 1/4 c all-purpose flour

1 c old fashioned whole oats

1/2 tsp baking soda

3/4 c white chocolate chips

1/2 c peanut butter chips (or use butterscotch chips, chocolate chips, toffee bits, raisins, nuts, seeds, etc.)


In a medium-sized microwave safe bowl, melt the butter and peanut butter together.  Power on for 30 seconds, take out, stir.  Repeat.  Should take no more than about 90 seconds.

Add the brown & white sugar to the melted butter & peanut butter mixture and stir.  Set this is the freezer for a couple minutes.

Remove from the freezer (or just wait for the mixture to come to room temp on it’s own) and add the egg + yolk (you just don’t want to add eggs to that hot mixture.  We don’t want scrambled eggs here), add the vanilla extract, and stir.

Then add the flour, oats, baking soda and stir.  You should have cookie dough consistency dough and if you don’t, either add a touch more flour if it’s too wet or a touch more peanut butter if it’s too dry.

Finally, add the white chocolate chips and peanut butter chips and stir.

Roll or spoon out golf ball sized balls onto a cookie sheet, about 2 inches apart.  They spread but not tons.

Bake at 325F for approximately 10-12 minutes.  (I like very underdone and soft cookies so I baked for 10 minutes)  The cookies will look pretty raw even at 12 minutes and that’s ok.  Take them out and let the sit and cool well before eating.

  6. I just came across this recipe on Pinterest!! They look & sound amazing!! I would love to try these today but noticed I only have quick cooking oats … I’m sure they are different or recipes would just call for oats but do you think these would work? I hope so!

    • I haven’t tested it with quick oats (which behave more like flour than they do oats) so if you do try them, you’ll want to start with less than the amount called for in the recipe since they’ll dry out and bulk up your dough faster, more like flour.

  7. ok thanks so much for responding … guess I need to go shopping first :) can’t wait to try them though!!

  8. I found these on Pinterest. Your recipes are always awesome and these cookies did not disappoint. Thanks for sharing your amazing skills and recipes :)

  11. Spectacular cookie! The texture is wonderful. When they first come out of the oven they look too puffy to be the chewy goodness that they become when they cool. They are good as is, but we opted to use all PB chips for the second batch and we liked those even more. My kids want to try with chocolate chips – we’ll see – I’m worried it will overpower the pb goodness. My husband says they taste like chewy nutter butters.

    The only thing I did differently is dark brown sugar because I don’t have light brown. So feel free to make that substitution if you need to. You won’t be disappointed!

  15. These were DELICIOUS! I don’t have peanut butter chips, so I just left them out rather than replace them with anything because I didn’t want anything complicating/overpowering the flavors you’ve already got going in these cookies. And I loved them! Yum! They were pretty sweet, though. Maybe next time I’ll use less sugar. Or maybe not. :D

  16. Just made these and let me tell you they are more than delicious! I used both semi sweet chocolate chips and white chocolate chips and I couldn’t stop eating them! I followed the recipe step by step and will definitely be making these again soon. Thanks for the recipe :)

  17. I just made these and they were amazing.

    I followed most of the recipe, but used chunky peanut butter, and added a 1/2 cup of toasted almond slivers and flax seeds instead of the peanut butter chips.

  18. Loved reading this! I’m new to baking so very excited to make these, question, what would happen if you used salted butter instead of unsalted? Thanks

    • Nothing other that they’ll be saltier and I wouldn’t add any additional salt to the recipe. Brands of butter, and even from stick to stick, vary widely in how salty they are which is why I always use unsalted to control the salt in my sweets.

  19. Can natural peanut butter be used in lieu of what’s in the recipe? These look so good!

  20. Hey, these cookies look amazing and I really want to try baking some but not sure how to go about the measurements as I’m from the UK and am used to the metric system. Any idea what the measurements are in grams? I have no idea how to weigh out cups… Thanks!

  21. These rock! I skimmed the recipe before I went to the store, to make sure I had all the ingredients, but somehow I missed the peanut butter chips… I used semi sweet instead and loved it! I made a couple other changes… the only oats I had were quick oats, so I used them, and also added 1/2 t salt, as my husband is a huge fan of anything sweet-n-salty. Thanks for such a killer recipe!

  22. Best of three worlds! I sprinkled the tops with a tiny bit of flaky salt to contrast with the sweet. A keeper for sure, thank you! Finally a cookie me and the hubs both love.

  23. I love reading your blog and this was the first recipe I made from your site because well, I love oatmeal cookies, white chocolate chip cookies and peanut butter cookies! I made it as followed except I lowered the brown sugar to 3/4 cup and white sugar to 1/4 cup… still found it overpoweringly sweet. These cookies have amazing texture though! I would say it’s more like a peanut butter cookie than an oatmeal cookie.
