Recipe: Bittersweet Chocolate Mousse Cake with Creme Fraiche Whipped Cream

This chocolate cake was simply amazing! We used the recipe from the Williams Sonoma Christmas cookbook. The cake is both dense and fluffy, and not too sweet. The whipped cream is made with creme fraiche and left slight runny (see recipe below).

Creme Fraiche Whipped Cream
-1 C heavy whipping cream
-1/2 C creme fraiche
-1/2 C powdered sugar
-1 tsp vanilla

Make this when ready to serve the cake. Whip cream and creme fraiche together until it holds its shape, but not too firm. Whip in powdered sugar and vanilla. Scoop onto individual cake slices once plated. Sooo good!
