- 1 cup (170 g) mini semi-sweet chocolate chips (optional, for extra pockets of chocolate)
Chocolate Soak (optional but recommended)
- ½ cup (120 ml) chocolate syrup or melted chocolate thinned with 2 Tbsp cream
Chocolate Ganache Frosting / Drip
- 12 oz (340 g) semi-sweet or bittersweet chocolate, chopped
- 1½ cups (360 ml) heavy cream
- 2 Tbsp unsalted butter
Chocolate Buttercream (for filling & crumb coat)
- 1½ cups (340 g) unsalted butter, softened
- 4–5 cups (480–600 g) powdered sugar
- ¾ cup (65 g) unsweetened cocoa powder
- ½ cup (120 ml) heavy cream or milk
- 2 tsp vanilla extract
- Pinch of salt

Step-by-Step Instructions
Bake the Cake Layers
- Preheat oven to 350°F (175°C). Grease and line three 8-inch or 9-inch round cake pans with parchment.
- Whisk flour, cocoa, baking soda, baking powder, and salt.
- In a large bowl, beat sugars, buttermilk, oil, eggs, vanilla until smooth.
- Alternate adding dry ingredients and hot coffee to wet mixture, mixing until just combined. Fold in chocolate chips if using.
- Divide batter evenly among pans. Bake 28–35 minutes (toothpick comes out with moist crumbs). Cool in pans 10 min, then turn out onto racks to cool completely.
Make the Ganache
- Heat cream until simmering, pour over chopped chocolate. Let sit 2 min, then stir until smooth. Add butter, stir until glossy. Cool to spreadable consistency (about 30–60 min) or chill briefly for thicker texture.
Make Chocolate Buttercream
- Beat butter until creamy. Gradually add powdered sugar, cocoa, salt, then cream and vanilla. Beat on high 3–5 min until light and fluffy. Adjust with more cream/powdered sugar for desired consistency.
Assemble the Cake
- Level cake layers if needed. Place first layer on a cake board. Brush lightly with chocolate soak.
- Spread a generous layer of chocolate buttercream, then a thin layer of ganache. Repeat with second layer.
- Top with third layer, crumb coat entire cake with thin buttercream layer, chill 20–30 min.
- Frost smoothly with remaining buttercream. Chill again.
Add the Ganache Drip & Ice Cream Topping
- Warm remaining ganache slightly until pourable but not hot. Pour over top edge, letting it drip naturally down sides (use a spoon to guide drips).
- Chill 15–30 min to set ganache.
- Just before serving: pile scoops of ice cream high in the center, scatter generously with chocolate chips and chunks. Drizzle extra ganache over ice cream if desired.
Pro Tips for Perfect Results
- Use room temperature ingredients for even mixing and better texture.
- Don’t overmix the batter to avoid a dense cake.
- Let the ganache cool to the right consistency for easy dripping.
- Chill the cake between frosting layers to prevent crumbs in the final coat.
- Use a serrated knife to level cake layers for a professional look.
Variations and Substitutions
- Gluten-Free: Substitute all-purpose flour with a gluten-free blend.
- Dairy-Free: Use coconut milk instead of buttermilk and dairy-free chocolate.
- Healthier Option: Reduce sugar by ¼ cup and use Greek yogurt instead of buttermilk.
- Flavor Twist: Add a teaspoon of espresso powder to enhance the chocolate flavor.
Storage and Reheating Tips
- Store the cake in an airtight container at room temperature for up to 3 days or refrigerate for up to 5 days.
- To freeze, wrap individual slices in plastic wrap and store in a freezer-safe bag for up to 3 months.
- Reheat slices in the microwave for 10-15 seconds for a warm, gooey treat.
FAQ
Can I make this cake without coffee?

How do I prevent my ganache from splitting?
Ensure the cream is hot but not boiling, and stir gently until smooth.
Can I make the cake layers ahead of time?
Yes, bake and freeze the layers for up to a month. Thaw before assembling.
