Instructions
- Prepare Pans and Preheat Oven: Line two 8-inch cake pans with parchment paper circles on the bottom and grease the sides. Preheat your oven to 300°F (148°C) to create an even baking temperature.
- Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, natural unsweetened cocoa powder, baking soda, and salt until well combined for a uniform base.
- Add Wet Ingredients: Add eggs, milk, vegetable oil, and vanilla extract to the dry mixture. Mix thoroughly until the batter is smooth and evenly blended.
- Incorporate Hot Water: Slowly pour the hot water into the batter while mixing continuously to create a moist, tender cake crumb.
- Divide and Bake: Evenly distribute the batter between the prepared pans. Bake for 45-50 minutes or until a toothpick inserted in the center comes out with a few moist crumbs.
- Cool Cakes: Let the cakes cool in the pans for 2-3 minutes before transferring them to cooling racks to cool completely.
- Prepare Hot Chocolate Mixture: Dissolve the hot chocolate powder mix into 4 tablespoons of hot water or milk until thick and set aside for incorporation into frosting.
- Make Hot Chocolate Frosting – Cream Fats: Beat the unsalted butter and shortening in a large bowl until smooth and creamy.
- Add Powdered Sugar – First Portion: Gradually beat in half of the powdered sugar until smooth and well combined.
- Add Chocolate Mixture and Cocoa Powder: Mix in the prepared hot chocolate mixture and cocoa powder. Beat until completely blended and smooth.
- Add Remaining Powdered Sugar: Incorporate the rest of the powdered sugar and mix well for a thick frosting.
- Adjust Frosting Consistency: Add 1 to 2 tablespoons of water or milk to reach a spreadable consistency.
- Prepare Marshmallow Filling – Cream Butter: Beat 1/2 cup unsalted butter until creamy.
- Add Powdered Sugar: Beat in 1 cup powdered sugar until smooth.
- Incorporate Marshmallow Creme: Stir the marshmallow creme into the butter and sugar mixture until fluffy.
- Optional – Add White Chocolate Chips and Cream: Fold in white chocolate chips and heavy whipping cream to add richness and texture.
- Trim Cakes and Layer: Level cake domes with a serrated knife if needed and slice each cake horizontally into two layers, making four layers total.
- Assemble Cake Layer 1: Place the first cake layer on a plate and spread half a cup of hot chocolate frosting evenly over it.
- Pipe Dam and Add Marshmallow Filling: Pipe a frosting dam around the edge of the layer, fill the center with about 3/4 cup marshmallow filling, and spread evenly.
Notes
- Preheating the oven to a lower temperature (300°F) ensures even baking for this dense, moist chocolate cake.
- Slowly adding hot water to the batter helps create a tender crumb and enhances moisture.
- Using a frosting dam keeps the fluffy marshmallow filling neatly contained between the cake layers.
- White chocolate chips and heavy cream in the marshmallow filling are optional but add a nice richness and texture contrast.
- Allow cakes to cool completely before layering to avoid melting the frosting and filling.
- Decorate with mini marshmallows or marshmallow bits for a fun, festive look.
