Instructions

Prepare the Marbled Cake:

  1. Preheat Oven: Set your oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment paper.

  2. Mix Dry Ingredients: In a bowl, whisk together flour, baking powder, and salt. Set aside.

  3. Cream Butter and Sugar: In a large mixing bowl, beat the butter and sugar until light and fluffy.

  4. Add Eggs and Vanilla: Add eggs one at a time, mixing well after each addition. Stir in vanilla extract.

  5. Alternate Dry and Wet Ingredients: Gradually mix in the dry ingredients, alternating with milk until combined.

  6. Prepare Cocoa Swirl: In a separate bowl, mix cocoa powder with hot water to form a smooth paste. Take one-third of the batter and mix it with the cocoa paste.

  7. Create the Marble Effect: Pour the vanilla and chocolate batters into the pans in alternating dollops, then swirl gently with a skewer for a marbled effect.

  8. Bake: Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Let cakes cool completely.

Prepare the Milk Chocolate Ganache:

  1. Heat the Cream: In a saucepan, heat heavy cream until just simmering.

  2. Melt the Chocolate: Pour the warm cream over the chopped milk chocolate and let sit for a minute. Stir until smooth. Add butter and mix.

  3. Cool Slightly: Allow the ganache to cool until thick but pourable.

Prepare the Rocher Glaze:

  1. Mix Ingredients: Stir together melted chocolate, chopped hazelnuts, and vegetable oil until combined.

Prepare the Cocoa Whipped Cream:

  1. Whip the Cream: In a mixing bowl, whip the heavy cream with cocoa powder, powdered sugar, and vanilla extract until soft peaks form.

Assemble the Cake:

  1. Layer with Ganache: Place one cake layer on a serving plate, spread a generous layer of ganache, then place the second cake layer on top.

  2. Coat with Rocher Glaze: Pour the Rocher glaze over the top, allowing it to drip slightly over the edges.

  3. Decorate: Pipe cocoa whipped cream on top and garnish with extra chocolate shavings or hazelnuts.

Baking Pro Tips

  • Use room-temperature ingredients: This ensures a smooth batter and even baking.

  • Don’t overmix the batter: Overmixing can make the cake dense instead of light and fluffy.

  • Swirl the batter lightly: Too much swirling can blend the layers instead of creating a marbled effect.

  • Chill before slicing: Cooling the cake makes it easier to slice cleanly and layer with ganache.

  • Use high-quality chocolate: Better chocolate results in a richer ganache and glaze.
