Ingredients

For the almond sponge:
• 150 g almond flour
• 100 g sugar
• 4 large eggs
• 50 g melted butter

For the coffee syrup:
• 200 ml strong brewed coffee
• 50 g sugar

For the coffee buttercream:
• 100 g softened butter
• 50 g sugar
• 2 tablespoons strong coffee

For the chocolate ganache:
• 200 g dark chocolate, chopped
• 200 ml heavy cream

For the glaze:
• 100 g dark chocolate
• 2 tablespoons cream

Directions

Preheat the oven to 180°C. Line a baking tray with parchment paper.

In a bowl, whisk the eggs and sugar until pale and fluffy. Gently fold in the almond flour, then add the melted butter. Spread the batter thinly and evenly on the tray. Bake for 10 to 12 minutes, then cool completely.

Cut the sponge into equal rectangles. Mix the hot coffee with sugar to make the syrup, then let it cool.

For the ganache, heat the cream until steaming, pour it over the chopped chocolate, and stir until smooth.

For the buttercream, beat the softened butter with sugar until creamy, then mix in the coffee.

Place one sponge layer on a tray. Brush with coffee syrup. Spread a thin layer of coffee buttercream, then add ganache. Repeat the layers evenly.

Chill the cake for at least 3 hours. Pour the chocolate glaze over the top, smooth it, then chill again before slicing.
