Ingredients
- For the Chocolate Cake:
- 1 box Devil’s Food Cake Mix
- 1 cup water (or as directed on the box)
- 3 large eggs (or as directed on the box)
- ½ cup vegetable oil (or as directed on the box)
- For the Marshmallow Filling:
- 2½ cups marshmallow fluff
- 2 tablespoons water
- For the Chocolate Fudge Filling:
- 1¾ cups semi-sweet chocolate chips
- 14 oz (1 can) sweetened condensed milk
- 3 tablespoons heavy whipping cream
- For the Whipped Chocolate Topping:
- 2 cups heavy whipping cream
- 2 envelopes instant hot chocolate mix
- 1 teaspoon vanilla extract
- 3 cups mini marshmallows
- Optional:
- Hot fudge sauce (for drizzling)
Instructions
- Bake the Cake: Mix the Devil’s Food Cake Mix, water, eggs, and oil together, then pour into a sprayed 9×13-inch baking pan. Bake according to the package instructions. Let the cake cool for 20 minutes on a cooling rack.
- Poke the Cake: Using the round handle of a wooden spoon, poke holes in the cake about 1 inch apart, about two-thirds deep into the cake (not all the way to the bottom).
- Make the Marshmallow Filling: Place marshmallow fluff and water in a microwave-safe bowl. Microwave in 20-second bursts, stirring each time, until melted (about 2-3 minutes). Pour the liquefied fluff into a piping bag or a plastic bag with the corner snipped off. Pipe the marshmallow filling into the holes, then spread the remaining fluff over the top. Chill the cake in the fridge.
- Make the Chocolate Fudge Filling: Place the chocolate chips, sweetened condensed milk, and heavy whipping cream in a microwave-safe bowl. Microwave in 20-second bursts, stirring each time, until melted (about 2-3 minutes). Spread the fudge filling over the cake and chill until the chocolate is completely cooled.
- Make the Whipped Topping: Beat the heavy cream, hot chocolate mix, and vanilla extract with an electric mixer until stiff peaks form. Spread the whipped topping over the chilled cake. Garnish with mini marshmallows.
- Serve: Drizzle with melted hot fudge sauce if desired and enjoy!
Notes
- For extra indulgence, top with more mini marshmallows and drizzle with extra hot fudge.
- This cake can be stored in the fridge for up to 3 days, making it great for meal prep or make-ahead parties.
- You can use any chocolate cake mix if you don’t have Devil’s Food Cake Mix.
