This Flourless Chocolate Cake is a dense and decadent treat with a chocolate ganache on top. Made with simple ingredients, this flourless cake is impressive enough for dinner parties or Valentine's Day. It has a rich chocolate flavor.
Preheat the oven to 375°F and Lightly grease a metal 8" round cake pan; cut a piece of parchment to fit, grease it, and lay it in the bottom of the pan.
FOR THE CAKE: Place chocolate and butter in a microwave-safe bowl, and heat until the butter is melted and the chips are soft. Stir intermittently and heat more as needed. Transfer chocolate mixture to a mixing bowl.
Stir in the sugar, salt, and vanilla. Add the eggs, beating briefly until smooth. Add the cocoa powder, and mix just to combine.
Spoon the batter into the prepared pan. Bake the cake for 25-28 minutes; the top will have formed a thin crust, and it should register at least 200°F on an instant-read thermometer inserted into its center.
Remove it from the oven, and cool it in the pan for 5 minutes.
Loosen the sides of the pan with a table knife and turn it out onto a serving plate. The top will now be on the bottom; that's fine. Allow the cake to cool completely before glazing.
To make the glaze: Place the chocolate in a heatproof bowl. Heat the cream until it's not quite at a simmer, but showing fine bubbles around the edge. Pour the cream over the chocolate, stir very briefly to combine, and let rest for 5 minutes. Stir again — at first slowly, then more vigorously — until the chocolate is completely melted and the glaze is smooth. If any bits of chocolate remain, reheat briefly in the microwave or over a burner, then stir until smooth.
Spoon the glaze over the cake, spreading it to drip over the sides a bit. Allow the glaze to set for several hours before serving the cake. Cut with a sharp knife. Serve with fresh raspberries, a scoop of ice cream, or whipped cream.
