Chocolate Ganache Mousse Cake

This is one of my favorite cakes, It is rich and decadent and super easy to make. For the crust you can substitute with a cake layer instead by using :1/2 cup all-purpose flour 1/2 cup sugar 1/4 cup cocoa powder 1/2 teaspoon baking powder pinch of salt 1/2 cup yogurt 2 Tbs vegetable oil 1 egg *Tip: To easily cut cake, leave cake in springform pan; use hot dry knife to cut through top layer.
