This easy Peanut Butter Oatmeal Cookies recipe yields crisp edges, tender and chewy centers packed with peanut butter flavor and oats! My favorite oatmeal & peanut butter cookies can be customized with your favorite add-ins!
Preheat oven to 350°F. Line a baking sheet with parchment paper.
Add peanut butter, granulated sugar, brown sugar, and butter to the bowl of a stand mixer with the paddle attachment. Beat until creamed together.
Beat eggs in one at a time until well mixed. Beat in maple syrup and vanilla.
Stir in flour, rolled oats, quick oats, baking soda and salt until you get a cohesive dough. If using, fold in add-ins.
Using a medium cookie scoop, scoop and drop balls of cookie dough onto the prepared baking sheet, evenly spaced apart. Optionally, press Toppings into each ball. Using a fork, flatten cookies about halfway to medium thickness—they’ll spread a bit during baking. Press together any loose bits.
Bake cookies for 10-14 minutes. Mine took 12 minutes.
Cool cookies on sheet for 5 minutes. Transfer to a cooling rack to cool completely. Enjoy!
