  • 1 box (18.25 oz.) devil’s food cake mix
  • 2 large eggs
  • 2 Tbsp. water
  • 2 Tbsp. oil
  • 1⁄2 cup cocoa powder
  • 1 envelope (0.25 oz.) unflavored gelatin
  • 1⁄4 cup cold water
  • 1 cup vegetable shortening
  • 1 tsp. vanilla extract
  • 1 lb. plus 1 cup confectioners’ sugar


  • Preheat oven to 400°F. Grease a large baking sheet.
  • Combine cake mix, eggs, water, oil, and cocoa powder. Mix well using electric mixer on medium speed.
  • Butter your hands, form dough into balls, and place on the cookie sheet. Flatten each ball with the palm of your hand or a fork. Bake for 9 minutes.
  • Remove cookies to a paper towel. Flatten each cookie with the bottom of a clean mug. Let cool for 20 minutes.
  • In a small, microwave-safe bowl, mix gelatin powder and cold water. Heat in microwave until gelatin is transparent, about 15 seconds. Set gelatin mixture aside to cool completely.
  • Meanwhile, in a separate bowl beat the shortening until fluffy. Gently fold in vanilla and confectioners’ sugar. Mix cooled gelatin into shortening mixture.
  • Sandwich the filling between two cookies, rounded sides facing out.
