My friend, Betty, gave these cookies the ultimate compliment. She baked up a test batch for me. The next time I saw her she told me they were so good that she "hid them all in the back of her freezer so she wouldn't have to share them with anyone". A girl after my own heart! ❤️

MAKING YOUR OATMEAL PEANUT BUTTER CHOCOLATE CHIP COOKIES

This recipe comes together quickly and only takes a short 45 minutes to an hour of chill time. These oatmeal peanut butter chocolate chip cookies bake up so thick and chewy and are sure to satisfy all the cookie monsters in your life.

I use a #30 cookie scoop to get about 2 tablespoons of cookie dough per cookie. These cookies are definitely large so you'll want to give plenty of room between them on the baking sheet.

They will likely be a little puffy when you pull them out of the oven. I lightly press on the tops (with the palm of my hand) once removed from the oven to give them a less domed appearance.

cookie dough batter in mixer — I love using my SideSwipe blade! It does a great job creating light and airy creaming, but also easily handles all the oatmeal, peanut butter and chocolate chips in this cookie dough.

These chewy and plump oatmeal peanut butter chocolate chip cookies are so irresistible. I dare you to eat just one!

Servings 24 cookies

Author Tasia ~ twosugarbugs

Ingredients

¾ cup all-purpose flour
½ teaspoon baking powder
½ teaspoon baking soda
½ teaspoon salt
½ cup unsalted butter room temperature
½ cup brown sugar firmly packed (I prefer dark brown, but light brown works too)
½ cup granulated sugar
½ cup creamy peanut butter
½ teaspoon pure vanilla extract
1 large egg
2 cups old-fashioned rolled oats
1 cup chocolate chips

Instructions

In a medium size bowl, whisk flour, baking powder, baking soda and salt. Set aside.
Cream butter and both sugars on medium high with a stand mixer fitted with the paddle attachment, or a hand mixer, until combined. Add peanut butter and continue until light and fluffy. Approximately 3-5 minutes.
Scrape down your bowl and add vanilla and the egg. Mix until well combined.
With the mixer on low, add the flour mixture and blend until just combined.
Fold in oats and chocolate chips.
Chill 45 minutes to one hour.
Preheat oven to 350°F.
Prepare baking sheets with a silicone baking mat or parchment paper.
Using a cookie scoop (approximately 2 tablespoons of dough), place cookie dough on prepared baking sheet, spacing about 2 inches apart.
Bake 12-15 minutes, until edges are lightly browned. They will be a little puffy, I lightly press down on the tops once removed from the oven to give them a less domed appearance.
Allow to cool on the pan for 5 minutes and then transfer to a cooling rack to cool completely.

Notes

Cookies stay fresh in an airtight container for up to one week. Baked cookies freeze well for up to three months.

I do not recommend using natural peanut butter for these cookies. A brand like Jif or Skippy works best.

These sound fantastic - I haven’t made cookies in awhile (since I made your funfetti recipe) - I think I’m going to have to make these in the near future! 🙂

  Thank you Jenna! You get the trifecta of oatmeal, peanut butter and chocolate chips in these cookies, they are seriously addicting! You'll have to let me know if you make them.

Hi! I want to make these, but do not have peanut butter. Do you think (runny) tahini will work?

  Thank you for your interest in this recipe Monika! I have not tested this recipe with tahini so I am unsure of how they will turn out. I know that tahini can quite often be successfully used in place of peanut butter. If you are feeling adventurous, give it a try! Since your tahini is on the runny side I would probably chill the cookies a little longer to help them from spreading while baking. Please let me know how it goes!

    Thanks for replying. ONE more question. I can't use eggs...I need to preserve them.
    What can I use in their stead?!

      I've never used egg replacements in baking, but know there are different suggestions out there. I would search the internet for something like, "common egg substitutes in baking" and see if you have the ingredients they recommend. Please let me know if this experiment works out!

Love the combination of oats chocolate and peanut butter. However mine seemed a little dry/heavy on the oats. I used old fashioned oats. Should I have processed them a bit?

  Hi Patty, I use old fashioned oats in this recipe as well. I'm wondering how you measured them? To measure oats, use the same spoon and level method that you use with flour. If you scooped the measuring cup into the oats, you may have ended up with more oats, which could yield a drier cookie.

These were awesome and all that you built them up to be. I followed your advice and flattened them out of the oven and I also think it made them look better. Definitely a keeper and these will be my go to oatmeal cookies from now on. Thank you!
