These cake mix peanut butter cookies are soft, chewy, and full of classic flavor. An easy peanut butter cookies recipe made with just 4 simple ingredients.
Preheat oven to 350°F. Line 3 cookie sheets with parchment paper, and set them aside.
In a large bowl, combine the cake mix, peanut butter, oil, and eggs. Mix with an electric mixer until the dough is crumbly but moist.
13.25 ounce box yellow cake mix, 1 cup creamy peanut butter, ½ cup oil, 2 large eggs
Use a medium cookie scoop (1 ½ tablespoons) to scoop out balls of cookie dough and roll them between your palms until smooth. Place the cookie dough balls on the parchment-lined cookie sheets about 2 inches apart, and gently press a fork on top of the balls to form a crisscross pattern.
Bake the cookies, one cookie sheet at a time, for 10-12 minutes or until they start to brown around the edges, but they are still soft in the center.
Let the cookies rest on the cookie sheets for about 15 minutes before serving. Store in an airtight container on the counter for up to 4 days.
Notes
Storage :
Store: Keep cookies in an airtight container at room temperature for up to 4 days.
Refrigerator: Store in the fridge for up to 7 days; bring to room temp before serving.
Freeze: Freeze in a gallon bag for up to 3 months. Thaw overnight in the fridge, then bring to room temp.
Make ahead: Prepare dough balls and freeze them. Bake straight from frozen, adding 1-2 minutes to the bake time.
Tips:
Use yellow cake mix for a sweeter cookie, or white cake mix for a lighter taste.
Stick with creamy peanut butter for the best texture.
Chill dough for 20 minutes if it feels sticky.
Use a 1 ½ tablespoon scoop for evenly sized cookies.
For very soft cookies, pull them out at 10 minutes - they will firm up as they cool.
