This Strawberry Champagne Layer Cake is a showstopper dessert that is surprisingly easy to make. To make the cake layers, mix together a box of white cake mix, champagne, and oil. Divide the batter between three 9-inch cake pans and bake until golden brown. Once the cakes are cooled, stack them with layers of whipped cream frosting and fresh strawberries. This cake is perfect for a special occasion or as a centerpiece dessert for a dinner party.
