Ingredients
  

Whoopie Pie Cookie-Cakes with Cake Mix

  • 15 oz Devil's Food cake mix
  • ¾ cup Water
  • ½ cup Vegetable oil
  • 3 Eggs
  • 3.9 oz Instant pudding mix chocolate

Whoopie Pie Filling

  • 6 tbsp Unsalted butter softened
  • 2⅔ cups Powdered sugar
  • ⅓ cup Milk up to ½ cup milk, as needed
  • 1 tsp Vanilla
  • Food coloring drops Green

Decoration

  • Mini marshmallows
  • Edible icing pen

Instructions
 

Make Whoopie Pie Cookie-Cakes

  • Preheat oven to 350℉.
  • In a large mixing bowl, add the devil's food cake mix, water, vegetable oil, eggs, and instant pudding mix. Mix until smooth.
  • Grease whoopie pan molds.
  • Add batter about ⅔ full in each mold.
  • Bake for 10-12 minutes at 350℉ until whoopie cookie-cakes appear set and slightly pulled in from the edges of the mold.
  • Cool for 1-2 minutes before carefully turning out onto wire racks to cool completely.

Make Whoopie Pie Filling

  • In a mixing bowl, beat softened butter.
  • To the butter, add powdered sugar alternately with a little milk, beating after each addition until mixture seems consistent.*
  • Add vanilla and mix for another 10 seconds.
  • Add a few drops of food coloring and mix again until you have the desired green.

Decorate Whoopie Pies

  • Take one cooled whoopie pie cookie-cake. Spread a layer of filling before adding a second cookie-cake on top.
  • Decorate mini marshmallows with a single dot from an edible marker pen. Place 5-6 marshmallows all around each whoopie pie with the dot facing out - for a Frankenstein effect.

Notes

  • If frosting looks dry, add a bit of milk until the frosting comes to the right consistency. Or if not firm enough, add a bit more powdered sugar until frosting is thick enough for spreading.
