Rich Chocolate Cake

Preheat the oven to a moderate temperature (170°C)

Line the bottom of the baking pan with parchment paper

Butter and dust the baking pan with flour

Place a 22-25cm diameter hole in the middle, about 2/3 of the way down

Melt the chocolate over low heat

Remove from the heat

Place the eggs in a large bowl

Reserve 2 tablespoons of sugar and set aside

Add the remaining sugar to the eggs slowly, beating well for about 5 minutes with an electric mixer

Add the melted chocolate, ground cashews, brewed coffee, and rum or whiskey, mixing until fully incorporated

Beat the egg whites until stiff peaks form

Fold in the reserved sugar

Fold one-quarter of the egg whites into the egg yolk mixture to prevent weeping

Pour the batter into the prepared baking pan and smooth the top

Bake for 35-40 minutes, or until the cake is risen, the top is dry, and a toothpick inserted comes out almost clean

Let cool in the pan for 1 hour

Then, invert onto a serving plate

Dust with confectioner's sugar and decorate with grated chocolate and toasted cashews if desired

Serve 10-12 people.
