  • 1 cake mix box (I used yellow cake)
  • 1 cup Peanut Butter
  • 1/2 cup unsalted butter, softened (1 stick)


  • Mix with an electric mixer on medium speed all ingredients until everything is well incorporated, about 3-4 minutes.
  • Form a disk and place the dough between two pieces of parchment paper. Roll out dough to 1/2 inch thick. Refrigerate for 15 minutes.
  • Remove dough from refrigerator. Cut into desired shapes with cookie cutters. Place the cut cookies on a baking sheet lined with parchment paper and refrigerate for 15 more minutes.
  • Preheat oven to 350º F.
  • Bake the cookies for 8-10 minutes or until edges are lightly brown. Remove from oven and let them cool on the baking sheet for 10 minutes. Then place on a wire rack to cool completely.
  • When cookies are completely cool decorate to your taste. I decorated them as a ghost. I used white and black cookie icing and edibles little eyes.


The number of cookies depends on the size of your cookie cutter.
