How to make Oatmeal Chocolate Chip Peanut Butter Cookies:

Cream. To the bowl of a standup mixer (or a large bowl with an electric mixer), add the butter, sugars, and peanut butter. Beat on medium-high speed until fluffy and significantly lightened in color.

Add the eggs and vanilla. Add the eggs and the egg yolk one at a time, mixing until incorporated after each addition. Scrape down the sides of the mixing bowl and add the vanilla. Mix to incorporate.

Add the dry ingredients. Right on top of the wet ingredients, add the flour, baking powder, baking soda, salt, and cinnamon. Mix on low speed just until the flour mixture is incorporated. Scrape down the sides of the bowl.

Add the mix-ins. Add the oats and mix until just incorporated. Add the chocolate chips and mix until just incorporated.

Chill. Transfer the cookie dough to a large Ziplock bag and chill in the refrigerator for at least 1 hour or up to 3 days.

Prepare to bake. Preheat the oven to 350 ℉ and line 2 cookie sheets (you might need more depending on the size of the cookie sheet) with parchment paper.

Bake. Remove the cookie dough from the refrigerator. Use your hands or a large cookie scoop to form the dough into 2.5-inch balls. Arrange the dough balls on the prepared cookie sheets 2 inches apart. Bake cookies for 14 minutes. When they are done, let them cook on a wire rack.

Cool. Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to wire racks to cool completely.

Storage Suggestions

If you manage to not eat the whole tray of cookies immediately, these Oatmeal Chocolate Chip Peanut Butter Cookies store well. Once cookies have completely cooled, here is how you can store them:

Counter: Store in an airtight container in a single layer for up to 4 days at room temperature. If you want to try and get the cookies to last even longer without becoming crumbly cookies, add a slice of bread into the container of cookies. The bread will give the cookies something to draw moisture from.

Refrigerator: Store in an airtight container in a single layer for up to 7 days in a refrigerator.

Freezer: You can freeze precooked cookie dough for cookies later. Just roll out and freeze for 30 minutes, and then transfer to an airtight, freezer safe bag for up to 3 months. To store cooked cookies, let them cool completely before you put them in a freezer-safe bag for up to 3 months.

Best tips for making this peanut butter oatmeal chocolate chip cookie recipe:

If you can, stick with using old-fashioned rolled oats for this recipe. However, in a pinch, the quick oats can substitute.

For frozen cookie dough, scoop the giant cookies into balls and then freeze them on a sheet. Once frozen transfer them to a freezer bag and pull one or more of the cookie dough balls out when you want a cookie.

Mix up the flavors with either peanut butter chips or even butterscotch chips, or make a triple-chip cookie!

Always chill the cookie dough when making cookies. However, if you want to skip that step, press the cookies into a 9×13 inch pan to make cookie bars and bake them at 350 ℉ for 25-30 minutes until they are cooked through to your liking.
