Ingredients
  

For the Cake:
  • 1 box chocolate fudge cake mix 15.25-ounce
  • 1 box instant chocolate fudge pudding mix 3.9-ounce
  • ¾ cup water
  • ¾ cup vegetable or canola oil
  • 4 large eggs
  • 1 cup sour cream or Greek yogurt
  • 1 teaspoon vanilla extract
For the Filling:
  • 10 tablespoons unsalted butter room temperature
  • 1 jar marshmallow creme 7-ounce
  • a pinch salt
  • 1 teaspoon vanilla extract
  • 2 cups powdered sugar divided
  • ½ cup chocolate chips
  • 3 tablespoons whipping cream

Equipment

  • Mixing bowls
  • Electric mixer
  • Measuring cups and spoons
  • Baking Pans
  • Offset spatula
  • Cooling rack

Method
 

Step-by-Step Instructions:
  1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans to ensure easy release once baked.
  2. In a large mixing bowl, combine the chocolate fudge cake mix, chocolate fudge pudding mix, water, vegetable oil, eggs, sour cream (or Greek yogurt), and vanilla extract. Using an electric mixer, beat on medium speed until the batter is smooth and well combined, about 2 minutes.
  3. Divide the batter evenly between the prepared cake pans. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Allow the cakes to cool in the pans for 10 minutes, then transfer to a cooling rack to cool completely.
  4. In a mixing bowl, beat the room temperature butter until creamy. Add the marshmallow creme, a pinch of salt, and vanilla extract, mixing until smooth. Gradually add the powdered sugar, starting with 1 cup, and mix until combined. If the filling is too thick, add the whipping cream a tablespoon at a time until you reach your desired consistency.
  5. Once the cakes are completely cool, place one layer on a serving plate. Spread a generous amount of the marshmallow filling over the top. Sprinkle chocolate chips evenly over the filling. Place the second cake layer on top and spread the remaining filling over the top and sides of the cake.
  6. For an extra touch, you can sprinkle additional chocolate chips on top of the cake or drizzle melted chocolate over it. Slice, serve, and enjoy the decadence of your Chocolate Whoopie Pie Cake!

Notes

  • Ensure butter is at room temperature for the filling to achieve the right consistency.
  • Allow cakes to cool completely before frosting to prevent melting and slipping.
  • Use an offset spatula to spread the filling evenly and avoid tearing the cake layers.
