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.

  1. tollhouse oatmeal scotches have always been my favorite…until now!! OH MY GOSH how amazing!! And you don’t need a mixer -what! Is this real life?!   I used butterscotch chips since I had some leftover from making your oatmeal cookie (chilling in the fridge now, along with your chocolate chip cookies). Can’t wait to try more of your recipes ! 

    • Thanks for trying the recipe and I’m glad you’re on a cookie-making streak! Thanks for trying lots of my cookie recipes and great to hear you’re happy! And amen to no mixer recipes :)

  2. I just finish baking this recipe. Its AMAZINGLY delicious~ but then I made a change to the flour. I used
    self-raising flour and custard flour . thanks for sharing. love Pinterest. 

  3. Have you tried making the dough ahead of time? We will be visiting family for Thanksgiving and thought it would be awesome to make a big batch of dough ahead of time and bring it up with us so we could make cookies whenever we wanted at their house. Normally refrigerating the dough helps it keep from spreading during baking and makes them chewier but I’ve never tried it on a cookie recipe that didn’t call for refrigerating the dough on purpose. Can’t wait to try these!

  5. Currently snowed in and bored out of my mind. Had everything on hand except for peanut butter chips, so I did 1 cup of white chocolate chips and didn’t substitute for anything else. They are perfect and delicious. Thank you!

  6. I’m a little excited about these. I have a husband and five kids (first three are boys!) and we play hard and eat cookies like it’s our job. I did add 1/2 tsp. Salt and all chocolate chips because that’s how we roll. Big fan of cooks illustrated and of your site! Thank you!

  7. Averie, I LOVE this recipe. I’ve made it once as written, and once using 1 cup sugar + 1 tbsp molasses as a substitute for brown sugar. Both times came out perfect. Your recipes are always so well done. Sprinkle a bit of sea salt before baking and these cookies are my new favourite, too. Thanks for the consistently good recipes. 

  8. These cookies are really great. I love the combo of oats, white chocolate and peanut butter. I knew that egg whites causes dryness, but I didn’t know this about creaming butter and brown sugar and white sugar ratio. Good to know! I love all cookies – crispy ones and chewy ones, but when I want chewy – I’d like to achieve chewy one :) Now I know the clue.

  9. Do you think you could use cookie butter in place of peanut butter for these?? yum!

  10. I realized about an hour ago that I needed to bring something to a cookie swap tonight, and I remembered that I’d bookmarked this recipe (via a post on another blog). 30 minutes start to finish with ingredients I already had in the house, and so yummy! Thanks so much Averie!

  11. I agree this would have to be one of my very favorites. I made a double batch. I love all your recipes! I also made a double batch of your oatmeal chocolate chip cookies for my brother. It’s what he requested for his birthday. He’s going to love them. Thank you for all the wonderful recipes!
