Prep time: 10 min  |  Cook time: 15 min  |  Total: 25 min



1 box yellow cake mix

1 cup creamy peanut butter

2 eggs

1/2 cup vegetable oil

Peanut Butter Glaze

1/2 cup butter

2/3 cup creamy peanut butter

6 Tbsp milk

2 1/2 cups powdered sugar

1 tsp pure vanilla extract


  1. Preheat oven to 350 degrees. In a large bowl or a stand mixer, combine all the cookie ingredients together and mix until just combined. Dough will be thick.
  2. On a Silpat or parchment lined cookie sheet, scoop cookie dough onto the cookie sheet. About 1 1/2 Tablespoon size. These don’t spread so you don’t have to space them too far apart.
  3. Bake for 9-10 minutes. Remove from the oven and take the bottom of a small glass and press down the cookies to flatten them. Let cool while preparing the peanut butter glaze.


  1. In a small saucepan over medium heat, add the butter, peanut butter and milk and bring to a boil. Once boiling, turn to low heat and add powdered sugar and vanilla extract. Whisk together until combined and smooth.
  2.  Spoon glaze over cookies making sure to cover the entire tops of the cookie. Let the glaze set and then dive in! Enjoy!


You can make this a Chocolate Peanut Butter Cookie just by switching the yellow cake mix for a chocolate one! Everything else is the same. So good!
