The combination of chewy rolled oats, creamy peanut butter, and chocolate chip nuggets is a perfect balance of flavors and textures for a chewy peanut butter oatmeal cookie.
This recipe is super easy to make, and can be whipped up in a jiffy after dinner. You can use any size scooper, but I used a regular sized ice cream scooper to make these giant cookies.

Do you have foods that bring up a long ago memory that's even more delicious than the food? This cookie is one of them for me.
The day I first had these was a rainy day in Portland, Oregon. My oldest granddaughter was around 6 years old at the time, and we made a pasta dinner with her mom, including making homemade pasta. (A fabulous way to spend a rainy afternoon, IMO.)
My stepdaughter and I made a game out of it to keep little Natalie engaged, attention spans of a 6-year-old being what they are. It was such fun. And then she surprised us with these cookies afterwards, for us all to enjoy together. Both this memory and these cookies were delicious.
🧅 Ingredient Notes
For the all of the ingredients, measurements, and directions, go to the Recipe Card at the bottom of this post.
- All-purpose flour - I like King Arthur flour for it's consistency.
- Brown sugar - If you don't have any on hand, it's easy to make your own brown sugar.
- Peanut butter - A cheaper brand of peanut butter, such as Skippy, is better in this recipe than with the healthier, natural, peanut butters.
- Rolled oats - Don't use instant oats in this recipe.
- Chocolate chips - Semi-sweet chocolate and milk chocolate chips both work great in this recipe.
📝 Instructions Overview

🎯 Preparation Tips
- Don't over-stir the cookie dough, as this can make the cookie dough tougher. I recommend adding the flour, oats, and chocolate chips by hand using a silicone spatula.
- Chill the dough before scooping little mounds onto a cookie sheet. Otherwise they'll spread too much. Also, be sure to space them 2-inches apart on the cookie sheet to allow some spread.
- Do not over-bake these cookies if you want them soft and chewy! I pull them from the oven once the outside edges look firm, and then cool on a cooling rack to allow them to set up.
- If making these cookies in batches, run cool water over the cookie sheet from the first batch to cool it down before add scoops of dough onto it for the second batch.
👩🍳 FAQ
The most important piece of equipment in baking cookies is a cookie sheet. This may seem obvious, but many folks think a baking sheet is the same thing.
Check out this post for the important differences between baking sheets and cookie sheets.
Additionally, I prefer cookie sheets that are insulated. This means hot air circulates between two layers of whatever the cookie sheet is made out of. This promotes an even baking, and makes it almost impossible to bake cookies with burned bottoms.

Peanut Butter Oatmeal Cookies with Chocolate Chips
Equipment
- Cookie scoop I used the large size for large cookies
Ingredients
- ¾ cup (3.375 ounces) all-purpose flour
- ½ teaspoon baking soda
- ½ teaspoon kosher salt
- ½ teaspoon baking powder
- ½ cup unsalted butter room temperature
- ½ cup granulated sugar
- ¼ cup packed brown sugar
- ½ cup peanut butter (See the Recipe Notes)
- 1 large egg
- 1 teaspoon vanilla extract
- 1 cup rolled oats
- ½ cup chocolate chips
Instructions
- Preheat the oven to 350° F and line a cookie sheet with parchment paper.
- Whisk together the flour, baking soda, salt, and baking powder in a medium bowl to thoroughly distribute the baking soda and powder through the flour. Set aside.
- In a large bowl, use a hand mixer to beat the butter and sugar together until fluffy, about 3 minutes. Beat in the brown sugar. Add the peanut butter to the bowl along with the egg and vanilla extract. Beat on a low speed until they're incorporated into the dough.
- Add the dry ingredients to the bowl, and mix into the dough using a silicone spatula. Fold in the oats and chocolate chips.
- Transfer the dough to a medium bowl, and chill in the freezer for a quick 15-minute chill. Using an cookie scoop, scoop the dough onto the prepared cookie sheet. 2 inches apart. These cookies will spread.
- Slide the cookie sheet into the oven and bake for 12 - 14 minutes. When the cookies are done, they'll be golden brown with their edges firming up. They will be fall-apart soft, so let them cool on a wire rack for 10 minutes before eating them. You will need to bake these cookies in batches. Be sure to cool the cookie sheet down before scooping more cookie dough onto it. And put the leftover cookie dough in the freezer between batches.
Notes
Ingredient Notes
- You will have better baking results with a cheaper brand of peanut butter, such as Skippy, than with the healthier, natural, peanut butters.
Instruction Notes
- Sometimes I like a thin crispy cookie, for example to go with ice cream. For that, I beat the butter and sugars together for a couple of minutes in a standing mixer, fitted with a paddle attachment. The butter should turn a slightly lighter, and will become fluffy. I add the egg, and continue beating for another minute or two, before folding in the dry ingredients.

EA Stewart
These sound so incredibly yummy, and I love your idea to freeze the dough in balls to bake later. I'd love to try making a gluten-free version which should be easy since there is very little flour. So happy you joined #cookie love !!
The Wimpy Vegetarian
I just saw your comment here, EA Stewart! I thought I replied to it already - my apologies. Yes, a gluten-free version shouldn't be difficult to do at all. As you say - there's very little flour in them to begin with!
The Wimpy Vegetarian
Thanks EA Stewart! Going gluten-free with these should definitely be easy :-). I have really enjoyed doing #cookie love with you guys!! I've got a ton of really great cookie recipes now!!
