With Easter approaching, pastry chef Nicolas Paciello brings chocolate to center stage in his take on a chocolate-vanilla marble cake. His Instagram post reveals a nostalgic, tender crumb with a hidden milk-chocolate ganache center and a crunchy rocher-style glaze. This is the same loaf sold in his boutique, and the recipe is simple enough to try at home.
Ingredients for the chocolate ganache, marble cake, and rocher glaze
- For the milk-chocolate ganache:
- 110 g milk chocolate
- 65 g cream
- 20 g butter
- For the marble cake batter:
- 155 g butter, softened
- 200 g granulated sugar
- 70 g brown sugar
- 200 g whole eggs
- 275 g all-purpose flour
- 10 g baking powder
- 70 g milk
- 15 g cocoa powder
- For the rocher-style glaze:
- Melted chocolate
- Grapeseed oil
- Chopped almonds
How to make the milk-chocolate ganache
Quick emulsion for a soft, pipeable center
- Warm the cream in a small saucepan until it simmers gently.
- Pour the hot cream over chopped milk chocolate and let sit for 1 minute.
- Stir until the mixture becomes smooth and glossy.
- Add the butter and mix until fully incorporated.
- Chill the ganache in the fridge until it firms enough to pipe.
Preparing the marble cake batter
Build a tender base for the chocolate insert
- Beat butter with both sugars in a stand mixer until pale and even.
- Incorporate the eggs gradually, mixing after each addition.
- Sift together flour and baking powder, then fold into the batter in two additions.
- Pour in the milk and mix until the batter is smooth and shiny.
- Remove about one third of the batter and stir in the cocoa powder to create the dark strand.
Assembly, baking, and creating the ganache insert
Layering technique for a neat marble and hidden center
- Line a loaf pan or use an insert mold to reserve a cavity for the ganache.
- Spoon a layer of plain batter into the pan.
- Add a layer of cocoa batter, then finish with another layer of plain batter.
- Bake at 150°C (300°F) for about 50 minutes, until a skewer comes out mostly clean.
- Let the cake cool slightly, then use a piping bag to fill the central cavity with chilled ganache.
Make the rocher-style chocolate glaze and finish the cake
- Combine melted chocolate with a drizzle of grapeseed oil for shine.
- Stir in chopped almonds for crunch and texture.
- Pour the glaze over the chilled marble cake to coat it evenly.
Chill briefly so the glaze and ganache set firmly before slicing.
Pro tips from the chef for a clean result
- Use a proper insert ring or small mold to preserve the ganache cavity.
- Line the pan with parchment for easier unmolding and cleaner edges.
- Cool the cake slightly before filling, so the ganache does not melt into the crumb.
- Freeze or refrigerate the loaf for a few minutes before glazing for a crisp finish.
- Toast the chopped almonds lightly for extra flavor in the rocher glaze.
