I've re-tested this recipe countless times in order to achieve Chewy Peanut Butter Cookies that are chewy, rich, and genuinely delicious. These are the perfect one-bowl peanut butter cookies and the only one you'll need.
Preheat oven to 375F with rack on lower middle position.
In the bowl of a stand-mixer, beat together the brown sugar, peanut butter, butter, and egg on medium speed until creamy.
Add flour, baking soda, baking powder, and salt; mix on low speed just until combined. Do not over-mix.
Shape dough into 1 ½ inch dough balls and place 3 inches apart on a parchment-lined cookie sheet. If desired, use fork to slightly flatten each dough ball just enough to create criss-cross design.
Bake 10-11 minutes or until lightly golden brown. Let cool on baking sheet 5 minutes before transferring to cool completely on wire rack before serving.
Notes
Use creamy peanut butter that’s already fully mixed and doesn’t have oil separation, for best flavor and texture.
Customize your cookies with fun mix-ins like peanut butter chips, chocolate chips, chopped Reese’s peanut butter cups, M&M’s, or toasted chopped peanuts for extra texture and flavor.
The criss-cross pattern is totally optional - these cookies bake up beautifully even without it, so feel free to skip that step if you're in a hurry.
You can freeze the cookie dough in an airtight container for up to 2 months. Just scoop, freeze, and bake straight from frozen - add a minute or two to the bake time.
Baked cookies also freeze well. Store them airtight for up to 1 month and enjoy soft, chewy peanut butter cookies anytime.
