👨🍳 Preparation
Step 1: Make the Cake Layers
- Preheat oven to 350°F (175°C). Grease and flour two 8-inch or 9-inch round cake pans.
- In a large bowl, whisk together flour, cocoa, baking powder, baking soda, and salt.
- In another bowl, beat sugar, brown sugar, and oil. Add eggs one at a time, then mix in buttermilk and vanilla.
- Gradually mix in the dry ingredients. Slowly stir in hot water or coffee.
- Divide batter between pans and bake for 25–30 minutes, or until a toothpick comes out clean.
- Cool in pans for 10 minutes, then turn onto a wire rack to cool completely.
Step 2: Make the Chocolate Custard
- In a medium saucepan, whisk together sugar, cocoa, cornstarch, flour, and salt.
- Whisk in egg yolks and milk until smooth. Cook over medium heat, stirring constantly.
- Once mixture thickens and starts to bubble, cook for 1 more minute.
- Remove from heat. Stir in butter, vanilla, and optional chopped chocolate. Cool to room temperature.
Step 3: Assemble the Cake
- Slice cake layers in half horizontally for four layers, or keep two thick layers.
- Place one cake layer on a serving plate. Spread a generous layer of custard on top.
- Repeat with remaining layers, ending with a cake layer on top.
- Chill the cake in the refrigerator for at least 1 hour to firm up.
Step 4: Optional Ganache Topping
- Heat cream in a small saucepan until just simmering. Pour over chopped chocolate.
- Let sit for 2 minutes, then stir until smooth.
- Pour ganache over chilled cake, letting it drip down the sides. Chill again until set.
💡 Tips for Success
- Use room-temperature ingredients for a smoother cake batter and custard.
- Don’t overbake the cake, as it will dry out. Start checking at the 25-minute mark.
- Cool the custard completely before layering to prevent melting the cake.
- For clean slicing, refrigerate the cake for at least 4 hours or overnight.
- Add parchment rounds to the bottom of the pans to prevent sticking.
🍫 Recipe Variations

Gluten-Free:

- Check that your chocolate and cocoa are certified gluten-free.
❓ FAQs
Q: Can I make this cake in advance?
A: Absolutely. You can make the cake layers and custard a day ahead and assemble it when ready. It actually tastes better after chilling overnight.
Q: How do I store leftovers?
A: Cover and refrigerate for up to 4 days. The custard keeps the cake moist and delicious.
Q: Can I freeze the cake?
A: You can freeze the cake layers separately. Wrap tightly and store up to 2 months. Custard doesn’t freeze well, so assemble fresh.
Q: Can I use a cake mix?
A: Yes! Use a chocolate cake mix to save time, then focus on making homemade custard for that rich, authentic flavor.
Q: My custard is too thin. What do I do?
A: Keep cooking while stirring—it thickens as it simmers. If it still doesn’t thicken, add a slurry of 1 tbsp cornstarch + 2 tbsp milk and return to heat.
