Soft Peanut Butter Oatmeal Cookies
Does anyone else struggle with cookie cravings when you want two different kinds? I love peanut butter cookies and oatmeal cookies, so I decided why not just combine them into one amazing cookie? That’s how I came up with these cookies – they are the best of both worlds!
Why you’ll love this recipe
With these two-in-one cookies, you get the peanut butter flavor but in a soft and chewy oatmeal cookie. It is a match made in cookie heaven, and the even better news is you can easily customize them with your favorite add-ins. So, leave them plain or dress them up – either way, you are going to love them.
Ingredients You Need
- Creamy peanut butter – just use regular peanut butter not natural or homemade. You can use a product like Skippy or Jif Naturals (as long as it’s a no-stir peanut butter). Creamy or Crunchy will work.
- Milk – remember this is my peanut butter cookie secret ingredient for soft cookies!
- Cinnamon – a must in any oatmeal cookies
- Quick-cooking oats – not old-fashioned or steel-cut. You can make your own quick oats if you only have the other kind!
- All-purpose flour – use the spoon and level method to measure
How to Make Peanut Butter Oatmeal Cookies
- Mix the softened butter and peanut butter in a large bowl with a mixer.
- Add granulated sugar and packed brown sugar and cream them with the butter mixture until light and fluffy.
- Add the egg, milk, vanilla extract, baking soda, cinnamon, and salt and mix until smooth.
- Add the oatmeal and flour and mix until combined.
- Scoop two tablespoons of the cookie dough to form each dough ball. Place them two inches apart on prepared baking sheets. Use a fork to make a hash mark on the top of each ball, lightly pressing them down. If the dough sticks to the fork, you can dip it in the granulated sugar.
- Bake cookies at 350°F for 11 to 14 minutes. The cookies are done when they are no longer glossy on top. Cool them on the baking sheets for five minutes before moving them.
Variations
These cookies are pretty fantastic all on their own – soft, chewy, with the perfect amount of peanut butter. But I love to dress them up, too! My favorite way is to make peanut butter oatmeal chocolate chip cookies, but there are other options, too.
You can add 1 ½ cup of add-ins – here are some ideas:
- Chocolate chips – milk, dark, semisweet, and white chocolate are great!
- Peanut butter chips or butterscotch chips
- Add Toffee Bits or chopped candy (like peanut butter cups)
- Chopped nuts like peanuts, walnuts, or almonds
Or, do a combination of add-ins – just be sure to keep the total amount to a cup and a half.
FAQs
For this recipe, you do. Quick oats cook faster than steel-cut oats and old-fashioned oats, so for this recipe, there’s not a substitute. Make your own quick oats by pulsing old fashioned in a blender or food processor for a few pulses!
Yes, for a different texture, you can sub creamy peanut butter for the chunky style.
I find that regular creamy peanut butter works best in cookies, and I haven’t tested this recipe with the natural kind (the type that you need to stir before using).
Yes, you can freeze oatmeal peanut butter cookies for up to a month. Keep them in a freezer-safe container and let them sit out at room temperature to thaw.
This depends on the type of cookie you’re making! For peanut butter oatmeal cookies they’re chewy because of the oats.

Nowhere in the recipe does it call for adding cream. It mentions “creaming” the butter and sugar, which is a mixing technique.
Really good! Would be great as part of a Christmas cookie mix!
I just made these with Natural Peanut Butter and mini chocolate chips. I will definitely make them again.
These cookies are SOOOO good!! I just made them this morning….when my “cookie monsters” get ahold of them there probably won’t be any left tonight! These are going into my favorites file. 🙂
Can you double this recipe successfully? Twenty two cookies would be gone in a flash around here!
Yes you can double it for sure!
The Quaker Oats recipe for Oatmeal cookies states you can use old fashioned oatmeal or the quick cook oatmeal in their recipes. Why does yours require the quick cook oatmeal?
It’s what I prefer to old fashioned 🙂
