Chocolate Cassis Cake

For the cake:

Baking spray for the springform pan

1 1/2 sticks of butter

10 ounces bittersweet chocolate, chopped

1/2 cup unsweetened cocoa powder

6 tablespoons creme de cassis liqueur

1 tsp pure vanilla extract

5 extra-large eggs, at room temperature

1 cup sugar

1/4 teaspoon kosher salt

For the glaze:

6 ounces bittersweet or semisweet chocolate, chopped

1/4 cup heavy cream

2 to 3 tablespoons creme de cassis liqueur

1/2 teaspoon pure vanilla extract

To serve:

1 pint fresh raspberries

1 pint fresh strawberries, hulled and thickly sliced

1/3 cup sugar

1/3 cup creme de cassis liqueur

Cake

Preheat the oven to 350° F.

Spray a 9-inch springform pan with baking spray.

Line the bottom of the pan with parchment paper and spray it again with baking spray.

Melt the butter and chocolate together in a heat-proof bowl set over a pan of simmering water, stirring occasionally until smooth. Set aside to cool for 5 minutes. Whisk in the cocoa powder, cassis, and vanilla and set aside.

Using a mixer (whisk attachment, if available), beat the eggs, sugar, and salt on high speed for 3 to 5 minutes, until pale yellow and triple in volume. Pour the chocolate mixture into the egg mixture and carefully but thoroughly fold them together with a rubber spatula. Pour the batter into the prepared pan and bake for 35 to 40 minutes, until just barely set in the center. Allow to cool in the pan for 30 minutes and then release the sides of the pan. Invert the cake carefully onto a flat serving plate, remove the parchment paper, and cool completely.

Glaze

Melt the chocolate and cream together in a heat-proof bowl set over a pan of simmering water. Stir until smooth. Off the heat, whisk in the cassis and vanilla. Allow to cool for 10 minutes and spread over just the top of the cake.

Fifteen minutes before serving, toss the berries gently with the sugar and cassis. Cut the cake in wedges and serve with the berries on the side.
