Ingredients

For the Joconde Sponge:

  • 6 large eggs
  • 6 egg whites
  • ¾ cup almond flour
  • ¾ cup powdered sugar
  • ½ cup all-purpose flour
  • 3 tablespoons unsalted butter, melted

For the Coffee Syrup:

  • ½ cup water
  • ¼ cup granulated sugar
  • 1 tablespoon instant coffee (no alcohol)

For the Coffee Buttercream:

  • ½ cup unsalted butter, softened
  • 2 egg yolks
  • ½ cup powdered sugar
  • 1 tablespoon instant coffee dissolved in 1 tablespoon hot water

For the Chocolate Ganache:

  • ½ cup heavy cream
  • ½ cup semi-sweet chocolate chips

For the Chocolate Glaze:

  • ⅓ cup semi-sweet chocolate chips
  • 2 tablespoons unsalted butter

Instructions

1. Prepare the Joconde Sponge

  • Preheat oven to 425°F (220°C). Line a large baking sheet with parchment.
  • In a large bowl, beat the eggs, almond flour, powdered sugar, and all-purpose flour until light and fluffy.
  • In another bowl, beat egg whites until soft peaks form. Gently fold into the almond mixture with the melted butter.
  • Spread evenly onto the pan and bake for 8–10 minutes, or until lightly golden.
  • Cool completely and cut into three even layers.

2. Make the Coffee Syrup

  • In a saucepan, bring water, sugar, and instant coffee to a boil.
  • Let cool completely before using.

3. Make the Coffee Buttercream

  • Beat egg yolks and powdered sugar until pale and thick.
  • Add softened butter and dissolved coffee. Beat until light, creamy, and fluffy.

4. Make the Ganache

  • Heat heavy cream in a saucepan until steaming, then pour over chocolate chips.
  • Let sit for 2 minutes, then stir until smooth.

5. Assemble the Cake

  • Place first sponge layer on a board. Brush with coffee syrup. Spread with half of the coffee buttercream.
  • Add second sponge. Brush with syrup. Spread with ganache.
  • Add third sponge. Brush with syrup. Spread remaining buttercream.
  • Chill the cake for at least 30 minutes to firm up before glazing.

6. Finish with Chocolate Glaze

  • Melt chocolate chips with butter until smooth. Spread evenly over the top of the chilled cake.
  • Chill again until the glaze is set. Slice carefully using a sharp knife for clean layers.

Tips for Success

  • Use a ruler to trim the edges for perfect presentation.
  • Don’t oversoak the sponge—just enough syrup to add flavor without sogginess.
  • Chill between layers to keep the structure neat and defined.
  • Serve slices at room temperature for the best flavor and texture.

Make-Ahead & Storage

  • This cake actually tastes better the next day!
  • Store covered in the refrigerator for up to 4 days.
  • Freeze individual slices (un-glazed) wrapped tightly for up to 1 month.
