Ingredients
(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)
All-purpose flour provides the structure needed for the cake layers, ensuring a stable base for the rich ganache.
Cocoa powder deepens the chocolate flavor and contributes to the cake’s dark, luscious color.
Granulated sugar balances the bitterness of cocoa and sweetens the cake perfectly.
Eggs add structure and richness while helping keep the cake moist and fluffy.
Butter enhances the overall flavor and provides tenderness to the crumb.
Baking powder ensures the cake layers rise evenly with a soft texture.
Milk adds moisture and keeps the cake from becoming too dense.
Heavy cream is key for creating the silky chocolate ganache that fills and coats the cake.
Dark chocolate serves as the base of the ganache, providing a rich, velvety finish reminiscent of truffles.
A splash of vanilla extract enhances the overall flavor and rounds out the richness.
Directions
Begin by preheating your oven and greasing cake pans. In a bowl, whisk together flour, cocoa powder, sugar, baking powder, and a pinch of salt. In a separate bowl, beat together butter, eggs, milk, and vanilla until smooth. Gradually add the dry mixture into the wet mixture, stirring until just combined. Divide the batter between the prepared pans and bake until a toothpick inserted in the center comes out clean.
While the cakes cool, prepare the ganache. Heat heavy cream in a saucepan until just simmering, then pour over chopped dark chocolate. Let sit for a minute before stirring until smooth and glossy. Allow the ganache to cool slightly so it thickens enough for spreading.
Once the cake layers are cooled, spread ganache between each layer, stacking them carefully. Use the remaining ganache to coat the outside of the cake, smoothing with a spatula for a polished finish. For added elegance, decorate with chocolate shavings, cocoa powder dusting, or fresh berries.
Chill slightly before serving to allow the ganache to set, then slice and enjoy the indulgence.
Servings and timing
This recipe makes about 10–12 servings, ideal for gatherings or celebrations. Preparation and baking take around 1 hour, while cooling and decorating require an additional 45 minutes. Altogether, the cake is ready in just under 2 hours.
Storage/reheating
Store the chocolate truffle cake in an airtight container at room temperature for up to 2 days, or refrigerate it for up to 5 days.
