FLOURLESS CHOCOLATE HAZELNUT CAKE: National Hazelnut Cake Day

Today is Hazelnut Cake Day! Hazelnuts are a staple in European baked goods. Did you know that hazelnuts are also known as filberts?

I'm always looking for a good flourless chocolate cake recipe, and this one for Flourless Chocolate-Hazelnut Cake adapted slightly from Epicurious is fabulous. Both Hazelnuts and Chocolate are heart-healthy. One caveat, hazelnuts are high in calories, but you're making a chocolate cake, so...what the hey! Don't have time to make this today?

Flourless Chocolate Hazelnut Cake

Ingredients 
12 ounces 60% cacao bittersweet chocolate, chopped
3/4 cup unsalted butter, cut into chunks
6 large eggs
1 cup (packed) golden brown sugar
1/2 cup Frangelico or other hazelnut liqueur, divided
1 cup (about 5 ounces) finely ground hazelnuts (ground in food processor)
1/2 tsp coarse kosher salt
1 cup chilled heavy whipping cream
Chopped toasted hazelnuts

Directions:
Put rack in center of oven and preheat to 350°F.
Butter 9-inch springform pan. Line bottom of pan with parchment paper round. Wrap outside of pan tightly with 3 layers of heavy-duty foil.
Combine chocolate and butter in medium metal bowl; set bowl over saucepan of simmering water. Whisk until mixture is melted and smooth. Remove bowl from over water.
Whisk eggs, golden brown sugar, and 1/4 cup Frangelico in large bowl to blend. Add chocolate mixture and whisk until smooth. Stir in ground hazelnuts and 1 teaspoon coarse kosher salt. Transfer batter to prepared pan.
Place springform pan in large roasting pan. Pour enough hot water into roasting pan to come halfway up sides of springform pan. Place in oven and tent springform pan loosely with foil.
Bake until cake is set in center and top is dry to touch, about 1 1/2 hours (top of cake will remain shiny).
Remove cake from roasting pan; remove foil from top and outside of pan.
Cool cake in pan on rack.
Chill cake until cold, about 3 hours. DO AHEAD: Can be made 3 days ahead. Cover and keep chilled.

Whipping Cream:
Using electric mixer, beat whipping cream and remaining 1/4 cup Frangelico in medium bowl until soft peaks form. Run knife around pan sides to loosen cake. Release pan sides.

Cut cake into wedges. Transfer to plates. Top with whipped cream; sprinkle with chopped toasted hazelnuts.
