Moist and light, the way good cake should be, and perfect for a child’s birthday party. If the whipped cream frosting doesn’t appeal, try making your favorite cream cheese frosting, substituting root beer extract for the vanilla.
Preheat the oven to 350 degrees F. Grease and flour two 9-inch round cake pans.
In a large mixing bowl, cream together the sugar and shortening until light. Sift together the dry ingredients and add to the creamed mixture, along with the root beer and extract. Beat well. In a separate bowl, beat the egg whites until stiff but not dry. Fold into the cake batter. Pour into the cake pans.
Bake for about 35 minutes or until a tester inserted near the center comes out clean. Cool in the pans for 10 minutes before turning out onto wire racks to cool. When the cake is completely cool, frost.
To make the frosting, beat the cream with the sugar and extract until stiff. Spread between the layers and on top of the cooled cake.
