Step-by-Step Instructions
1. Make the Chocolate Cake Layers:
- Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
- In a large bowl, sift together flour, cocoa powder, sugar, baking powder, baking soda, and salt.
- Add eggs, buttermilk, oil, and vanilla extract. Beat on medium speed until smooth.
- Stir in hot coffee—batter will be thin, but that’s the secret to moist cake.
- Divide batter evenly between pans and bake for 30–35 minutes, or until a toothpick comes out clean.
- Cool in pans for 10 minutes, then turn out onto wire racks to cool completely.
2. Prepare the Chocolate Custard Filling:
- In a saucepan, combine milk, cream, cornstarch, sugar, and salt. Whisk until smooth.
- Cook over medium heat, whisking constantly, until thickened—about 7–10 minutes.
- Remove from heat and stir in chocolate chips and vanilla until smooth and glossy.
- Transfer to a bowl and press plastic wrap directly onto the surface. Chill until set, about 1 hour.
3. Assemble the Cake:
- Level the cake layers if needed.
- Place one cake layer on a serving plate. Spread a thick layer of chilled chocolate custard on top.
- Add the second cake layer and gently press down.
- Chill the cake for 30 minutes to set the filling.
4. Make the Chocolate Ganache:
- Heat cream in a saucepan just to a boil. Remove from heat and pour over chopped chocolate.
- Let sit for 5 minutes, then stir until smooth. Add butter and stir until glossy.
- Cool for 10 minutes before pouring over the cake, letting it drip over the sides for a dreamy finish.

Frequently Asked Questions
1. Can I make Chocolate Dream Cake ahead of time?
Yes, this cake is ideal for making in advance. In fact, it tastes even better the next day as the flavors meld. You can bake the cake layers and prepare the custard up to 2 days ahead. Assemble the cake and add the ganache the day before serving. Store in the refrigerator, covered, and bring to room temperature before serving for best texture.
2. What can I use instead of buttermilk?
If you don’t have buttermilk, you can make a substitute by combining 1 tablespoon of white vinegar or lemon juice with 1 cup of whole milk. Let it sit for 5–10 minutes until slightly curdled. This homemade version mimics the acidity of buttermilk and helps the cake rise while keeping it tender.
3. How do I store Chocolate Dream Cake?
Store the assembled cake in the refrigerator, tightly covered or in a cake dome, for up to 4 days. Because of the custard filling and ganache topping, refrigeration is necessary to keep it safe and fresh. Let the cake sit at room temperature for about 30–45 minutes before slicing and serving for the best flavor and texture.
4. Can I freeze this cake?
Yes, you can freeze the chocolate cake layers and even the assembled cake. To freeze layers: wrap each completely cooled cake layer in plastic wrap and aluminum foil, then freeze for up to 2 months. For the assembled cake: chill until firm, then wrap tightly and freeze. Thaw overnight in the fridge, then bring to room temperature before serving. Note: Ganache may lose some shine after freezing but the taste remains intact.
