1 Box Pillsbury Devils Food cake mix
1/2 cup vegetable oil
Preheat oven to 350 degrees. Line two cookie sheets with parchment paper, or spray with non-stick cooking spray.
In a large bowl, add all ingredients and stir until well blended. Form walnut size balls and place on cookie sheets. (Makes about 25 cookies)
Bake for 8 minutes, remove from oven and let sit on cookie sheets for another 5 minutes. Transfer cookies to wire rack to cool completely.
Peanut Butter Filling:
1/4 cup unsalted butter, room temperature
1/2 cup creamy peanut butter
1 tsp pure vanilla extract
1 cup powdered sugar
1-2 T milk, as needed
In a large stand mixer, beat butter and peanut butter until combined. Add the vanilla extract and powdered sugar. Mix and slowly add milk as needed. Mix for 3 minutes.
When the cookies have cooled, you can add the peanut butter filling. Roll 1 T peanut butter filling mixture into a ball and place on smooth side of cookie. Place another cookie on top and press lightly to sandwich. Continue and assemble all cookies. Enjoy!
