Step-by-Step Instructions
Step 1 – Prepare the Cake Layers
- Preheat oven to 180°C (350°F) and grease three 8-inch round cake pans.
- In a large bowl, sift together flour, cocoa powder, sugar, baking powder, baking soda, and salt.
- In a separate bowl, mix eggs, buttermilk, oil, and vanilla extract until smooth.
- Gradually combine the wet ingredients with the dry mixture.
- Slowly add hot coffee and stir until the batter is glossy and well combined.
- Divide evenly among the prepared pans and bake 25–30 minutes, or until a toothpick comes out clean.
- Let cakes cool completely before assembling.
Step 2 – Make the Fudgy Chocolate Filling
- Heat heavy cream until just simmering.
- Pour over dark chocolate chips and butter.
- Let sit for 2 minutes, then stir until smooth and thick.
Step 3 – Make the Chocolate Buttercream Frosting
- Beat softened butter until creamy.
- Gradually add powdered sugar and cocoa powder.
- Mix in milk, vanilla, and a pinch of salt until fluffy.
Step 4 – Assemble the Cake
- Place one cake layer on a stand.
- Spread a thick layer of fudgy filling over it.
- Repeat with the second layer and filling.
- Top with the final cake layer.
- Frost the entire cake with chocolate buttercream, smoothing the sides.
Step 5 – Prepare the Chocolate Glaze
- Heat cream and pour over chopped dark chocolate.
- Stir until silky smooth and drizzle over the cake, letting it gently drip down the sides.
- Optional: Pipe frosting decorations along the edges for a polished finish.
Pro Tips for Success
- Room Temperature Ingredients: Eggs and butter at room temp create smoother batter and frosting.
- Do Not Overmix: Stir gently to prevent dense cake layers.
- Coffee Boosts Chocolate: Hot coffee enhances the chocolate flavor without tasting like coffee.
- Cool Completely Before Frosting: Warm cakes can melt buttercream or filling.
- Use an Offset Spatula: For a smooth, professional-looking frosting finish.
- Chill Before Cutting: Let the cake set in the fridge for cleaner slices.
Flavor Variations
- Mocha Twist: Add 1 tsp instant espresso to the batter for coffee lovers.
- Nutty Crunch: Fold in chopped toasted hazelnuts or almonds between layers.
- Berry Delight: Add fresh raspberries to the filling for a fruity contrast.
- Salted Caramel: Drizzle caramel sauce over the top before glaze.
- Peanut Butter: Swap part of the filling with creamy peanut butter for a chocolate-peanut combo.
