Instructions
Step 1: Bake the Cake Layers
- Preheat oven to 350°F (175°C). Grease and line two 8-inch round cake pans.
- In a large bowl, mix flour, cocoa, baking powder, baking soda, and salt.
- In another bowl, whisk eggs, sugars, oil, vanilla, and buttermilk. Mix into dry ingredients.
- Stir in hot water or coffee until smooth. Divide batter between pans.
- Bake for 30–35 minutes or until a toothpick comes out clean. Cool completely.
Step 2: Make the Custard Filling
- In a saucepan, heat milk until steaming.
- In a bowl, whisk egg yolks, sugar, and cornstarch until pale.
- Slowly whisk hot milk into yolk mixture, then return to saucepan.
- Cook over medium heat, stirring constantly, until thickened.
- Remove from heat, stir in butter and vanilla. Chill until firm.
Step 3: Make the Ganache
- Heat cream until just simmering. Pour over chopped chocolate.
- Let sit for 1–2 minutes, then stir until smooth. Stir in butter for shine.
Step 4: Assemble the Cake
- Slice cakes into layers if desired (for 3–4 thinner layers).
- Spread custard between each layer.
- Pour ganache over the top and let it drip down the sides.
- Chill for at least 1 hour before slicing for clean layers.
Tips for Best Results
- Use room-temperature ingredients for a smooth batter
- Chill custard well before assembling to prevent sliding
- For extra stability, add a thin buttercream dam around each layer
- Make 1 day ahead — it tastes even better chilled the next day!
