Cake
- 2 cups (260g) flour
- 2 cups (414g) sugar
- 3/4 cup (85g) natural unsweetened cocoa powder
- 2 tsp baking soda
- 1 tsp salt
- 2 large eggs
- 1 cup (240ml) milk
- 1 cup (240ml) vegetable oil
- 1 1/2 tsp vanilla extract
- 1 cup (240ml) hot water
Hot Chocolate Frosting
- 4 tbsp (60ml) hot water or milk
- 2.92 oz hot chocolate powder mix
- 1 1/2 cups (336g) unsalted butter, room temperature
- 1 1/4 cup (237g) shortening
- 10 cups (1150g) powdered sugar
- 2 tbsp (14g) natural unsweetened cocoa powder
- 1–2 tbsp water or milk (for consistency)
Marshmallow Filling
- 1/2 cup (112g) unsalted butter, room temperature
- 1 cup (115g) powdered sugar
- 10 oz marshmallow creme
- 6 oz (1 cup) white chocolate chips
- 3 tbsp (45ml) heavy whipping cream
- Mini marshmallows (optional, for decoration)
- Marshmallow bits (optional, for decoration)
Additional Frosting for Assembly
- 1/2 cup (112g) unsalted butter, room temperature
- 2 cups (230g) powdered sugar
- 1/2 tsp vanilla extract
- 1–2 tbsp water or milk (for consistency)
- Prepare Pans and Preheat Oven: Line two 8-inch cake pans with parchment paper circles on the bottom and grease the sides. Preheat the oven to 300°F (148°C) to ensure an even baking environment.
- Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, natural unsweetened cocoa powder, baking soda, and salt until evenly combined to create a uniform base for your batter.
- Add Wet Ingredients: To the dry ingredients, add eggs, milk, vegetable oil, and vanilla extract. Mix thoroughly until the batter is smooth and well combined, ensuring even texture throughout.
- Incorporate Hot Water: Slowly pour in the hot water and mix continuously to fully integrate it, which helps produce a moist and tender crumb in the cake.
- Divide and Bake: Evenly divide the batter between the prepared pans. Bake in the preheated oven for 45-50 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs attached.
- Cool Cakes: Remove the cakes from the oven and let them cool in the pans for 2-3 minutes, then transfer to cooling racks to cool completely, preventing overcooking and allowing easier handling.
- Prepare Hot Chocolate Mixture: Dissolve the hot chocolate powder mix into 4 tablespoons of hot water or milk until fairly thick. Set aside to incorporate into the frosting.
- Make Hot Chocolate Frosting – Cream Fats: In a large mixing bowl, beat the unsalted butter and shortening until smooth and creamy to form the base of the frosting.
- Add Powdered Sugar – First Portion: Mix in about half of the powdered sugar gradually, beating until the mixture is smooth and well combined.
- Add Chocolate Mixture and Cocoa Powder: Pour in the prepared hot chocolate mixture and add the 2 tablespoons of cocoa powder. Beat the mixture well until completely blended and smooth.
- Add Remaining Powdered Sugar: Incorporate the remaining powdered sugar, mixing thoroughly to achieve a consistent and thick frosting mixture.
- Adjust Frosting Consistency: Add 1 to 2 tablespoons of water or milk as needed to reach the desired spreading consistency for the frosting.
- Prepare Marshmallow Filling – Cream Butter: In a separate bowl, beat 1/2 cup of unsalted butter until smooth and creamy to start the filling base.
- Add Powdered Sugar: Beat in 1 cup of powdered sugar until well combined and smooth.
- Incorporate Marshmallow Creme: Stir the 10 oz marshmallow creme into the butter and sugar mixture until evenly blended, creating a fluffy filling.
- Optional: Add White Chocolate Chips and Cream: Gently fold in 6 oz white chocolate chips and 3 tablespoons heavy whipping cream for added richness; this step enhances texture and flavor but can be omitted if desired.
- Trim Cakes and Layer: If needed, use a large serrated knife to remove the domes from the top of each cake. Slice each cake horizontally into two layers to yield four layers total for stacking.
- Assemble Cake Layer 1: Place the first cake layer onto your cake plate or cardboard cake circle. Spread half a cup of the hot chocolate frosting evenly over the layer.
- Pipe Dam and Add Marshmallow Filling: Pipe a frosting dam around the outer edge of the first layer to contain the filling. Fill the center with about 3/4 cup of marshmallow filling and spread evenly.
Notes
- Use natural cocoa powder for a more authentic and deep chocolate flavor.
- Make sure the butter and shortening are at room temperature for smoother frosting and filling.
- To check cake doneness, a toothpick should come out with a few moist crumbs, not completely clean, for best texture.
- Optional white chocolate chips in the marshmallow filling add texture and richness but can be omitted.
- Keep cakes well cooled before frosting to prevent melting the frosting.
- Adjust water or milk in frosting to achieve your preferred consistency for easier spreading or piping.
- Decorate the cake with mini marshmallows or marshmallow bits for a festive touch.
