🥜🍪 My Oatmeal Peanut Butter Chocolate Chip Cookies are lightly crisp around the edges, soft, chewy, and LOADED with nutty flavor and rich chocolate chips in every bite! Why choose between oatmeal chocolate chip cookies, peanut butter cookies, or soft chocolate chip cookies when you can have them all?

Why You’ll Love These Chocolate Chip Peanut Butter Oatmeal Cookies
A personal favorite of mine, these cookies combine elements from all my favorite cookies. The recipe is adapted from and very similar to the Peanut Butter Oatmeal White Chocolate Cookie recipe, making it virtually foolproof.
- All you need is one bowl and a spoon, and these cookies are ready to eat in about 30 minutes.
- The higher ratio of brown to white sugar and egg yolk to egg white results in a super soft centers and a chewy texture.
- There’s no chilling required, and one batch makes 13 large cookies, making it the perfect treat for all your cookie cravings. I’d go ahead and make an extra batch before you find yourself snacking. They’re seriously addicting!


Ingredients You’ll Need
There’s a LOT of flavor packed into every bite of these cookies, all thanks to just a handful of simple ingredients. Here’s what you’ll need for this chocolate chip peanut butter oatmeal cookie recipe:
- Butter – I recommend using unsalted butter and letting it come to room temperature for easy mixing. Feel free to use margarine or a vegan butter for dairy-free cookies
- Sugar – The combination of brown sugar (light or dark) and granulated sugar sweetens the dough, adds a touch of molasses flavor, and contributes to the chewy texture
- Peanut Butter – Use creamy peanut butter. I recommend a brand like Jif or Skippy. Natural peanut butter tends to separate and cause greasy cookies. I also don’t recommend crunchy peanut butter, because it won’t incorporat into the dough evenly. Have leftover peanut butter? Check out my peanut butter cookbook to put it to good use!
- Eggs – For vegan cookies, substitute a flax egg
- Vanilla Extract
- Flour – I use all-purpose flour. If you need gluten-free cookies, substitute a 1:1 all-purpose gluten-free flour. Then, make sure to double-check the nutrition label on the rest of the ingredients
- Oats – Make sure to use old-fashioned oats. Quick oats and steel-cut oats will NOT work for this recipe! For gluten-free cookies, make sure to use certified gluten-free oats
- Baking Soda
- Mix-Ins – I use semi-sweet chocolate chips, but you can use milk chocolate chips or dark chocolate chips. Or, experiment with mix-ins like peanut butter chips, butterscotch chips, white chocolate chips, toffee bits, raisins, nuts, seeds, etc. I don’t recommend adding more than 1/2 cup, or your cookies will just be way too packed

How to Make Oatmeal Peanut Butter Chocolate Chip Cookies
- Melt the peanut butter and butter in the microwave in a large mixing bowl. Then, stir in the remaining wet ingredients. Wait a few minutes before combining ingredients to avoid scrambling the eggs! There’s no need for an electric mixer or stand mixer!
- Add the oats, followed by the remaining dry ingredients. Fold in the chocolate chips or mix-ins of choice.
- Portion the dough, and chill it in the fridge.
- Arrange the cookie dough balls on a silpat mat or parchment paper lined baking sheet, leaving space between each cookie. Bake until the edges and tops are just set. (I like very underdone and soft cookies, so I baked mine for 10 minutes) The cookies will look pretty raw even at 12 minutes, and that’s ok. Take them out and let them sit and cool well before eating.
- Cool on the pan. There’s no need for a wire rack!



Soft and Chewy Peanut Butter Oatmeal Chocolate Chip Cookies
Equipment
- 1 Large, Microwave-Safe Bowl
- 1 Cookie Sheet
Ingredients
- ½ cup unsalted butter, melted
- ⅓ cup creamy peanut butter
- 1 large egg + 1 egg yolk, discard extra white or save for another use
- ¾ cup light brown sugar, packed
- ½ cup granulated sugar
- 2 teaspoons vanilla extract
- 1 cup old-fashioned whole rolled oats, not instant or quick cook
- 1 ¼ cups all-purpose flour
- ½ teaspoon baking soda
- ½ teaspoon salt, or to taste
- ¾ cup semi-sweet chocolate chips
- ½ cup peanut butter chips, white chocolate or butterscotch chips may be substituted
Instructions
- To a large, microwave-safe bowl add the butter, peanut butter, and heat on high power to melt, about 1 minute. Stop to check and stir. Heat in 15-second increments until mixture can be stirred smooth.
- Wait momentarily before adding the egg and yolk so you don’t scramble them. Add the egg, sugars, vanilla, and whisk until combined. It’s okay if mixture is slightly granular.
- Add the oats and stir to combine.
- Add the flour, baking soda, salt, and stir to combine; don’t overmix. Dough is fairly thick.
- Add the chocolate chips, peanut butter chips, and stir to incorporate.
- Using a large cookie scoop, 1/4-cup measure, or your hands, form approximately 13 equal-sized mounds of dough, roll into balls, and flatten slightly. Tip – Strategically place a few chocolate chips on top of each mound of dough by taking chips from the underside and adding them on top.
- Place mounds on a large plate or tray, cover with plasticwrap, and refrigerate for at least 2 hours, up to 5 days. Do not bake with unchilled dough because cookies will bake thinner, flatter, and be more prone to spreading. Dough is a bit on the oily side before chilling and becomes less oily as it chills.
- Preheat oven to 350F, line a baking sheet with a Silpat or spray with cooking spray. Place dough mounds on baking sheet, spaced at least 2 inches apart (I bake 8 cookies per sheet).
- Bake for about 11 to 12 minutes (for very soft cookies, longer for more well-done cookies), or until edges have set and tops are just set, even if slightly undercooked, pale, and glossy in the center; don’t overbake. Cookies firm up as they cool.
- Allow cookies to cool on baking sheet for about 10 minutes before serving. I let them cool on the baking sheet and don’t use a rack.
Notes
- Cookies will keep airtight at room temperature for up to 1 week or in the freezer for up to 6 months.
- Alternatively, unbaked cookie dough can be stored in an airtight container in the refrigerator for up to 5 days, or in the freezer for up to 4 months, so consider baking only as many cookies as desired and save the remaining dough to be baked in the future when desired.

Chocolate Chip and Chunk Cookies – This is my new favorite chocolate chip cookie recipe for straight up chocolate chip cookies, without oats or peanut butter added. They are soft, chewy, tender, moist, a snap to make, and have two kinds of chocolate in every bite. They are my new go-to chocolate chip cookie recipe

New York Times Chocolate Chip Cookies (from Jacques Torres) – I learned many valuable lessons when making these cookies, from loving bread flour in cookies to detesting cake flour in them; to baking cookies bigger to stuffing in extra chocolate. The cookies are very good, and I loved them on the first day, and I wrote extensively about my thoughts overall on them.

Chocolate Chip Peanut Butter Oatmeal Skillet Cookie – This cookie combines three of my favorite cookies into one – chocolate chip, peanut butter, and oatmeal. The edges bake up crispy and chewy, and sweetened condensed milk is baked into the cookie, keeping the interior a literal hot, sweet, and gooey mess.



I made these tonight and they were far too sugary, and I love sugar, I definitely agree that they could do with less.
Thanks for trying them. We really like them but to each their own!
I made these yesterday and they came out great. I thought the total amount of sugar in this recipe seemed a tad high, so I reduced the brown sugar to 3/4 cup and left everything else the same. They tasted great and you’d never know I reduced the sugar! (I imagine maybe they spread more with more sugar?) The peanut butter keeps them moist and soft, but the peanut butter flavor is very subtle.
Good to know that a 1/2 cup reduction in brown sugar still works out okay! I don’t have problems with them spreading with the sugar I use as you can see in the photos. And in reality, 1/2 cup isn’t ‘all’ that much different for a whole batch of cookies; but in baking sometimes it is and would ruin things! So I never recommend people to just start ad-libbing and modifying recipes because sometimes that works out, and other times, not really. Glad you had success!
We are getting a blizzard today so I went through my Pinterest dessert board to find something to bake up with my daughter. We made these this morning (well, she watched from her high chair). :)
They are seriously amazing! I can’t stop eating them…I was planning to send some with my husband to work tomorrow, but I don’t know if they’ll last that long! The only changes I made were using milk chocolate instead of semi sweet chocolate chips, and using 1 cup brown sugar (I ran out!) and 3/4 cup granulated sugar. I baked them for 13 minutes and they are perfect! Thank you!
I’m so glad that you loved them and that you and your daughter were baking together…and if they don’t make it to tomorrow, there’s always more to be made, right! Glad that you were able to use the 1 c of brown sugar and they baked up perfectly for you!
I love this combination. Actually, I pretty much love all of your cookie recipes!
I also use a higher ratio of brown sugar, but I tend to brown my butter with nearly every recipe as I love the caramel flavor it brings out. These look incredible!
I am in love with ALL of your cookies. Every single one looks better than the next!
Do you use “salted” or “unsalted” butter for your cookies recipes? Also, Do you use the Kerrygold butter?
Your recipes look wonderful. I am going to make a couple of them for a cookie exchange.
Thanks for the gorgeous pictures, too.
Unsalted butter so I can control the salt rather than ‘wonder’ just how salty that salted butter was. I love Kerrygold but don’t buy it tons simply based on price. I bake far too much to be buying KG for every recipe!
these look amazing… must make them tomorrow! if i had the ingredients tonight i would make them now! have a wonderful week… thanks for sharing… x pam/red ticking
The cookies sound amazing and are on my BakeMeNow list. Whar I really want to know is: Where did you get the cookie scoop? I have had one for three years and I love it, but I have not been able to find another like it.
Bed Bath & Beyond – $3.99! They have them by the baking supplies in a big container, at least at my BB&B. Good luck!
These should be renamed “Sent From Heaven Cookies”. Because that is where they transport you. Ah-mazing! I used chunky peanut butter because that is what we had. The little peanut crunchers throughout the cookie made it even better! Pardon me while I go into my cookie coma now…
Naomi thank you for such a sweet comment! (These should be renamed “Sent From Heaven Cookies”)!
Glad you loved them and thanks for making them and coming back to LMK me know about it. And chunky PB could totally work with the little crunchy bits, ahhh, yes!
