This easy strawberry champagne cake recipe is perfect for those who want to impress their guests without spending hours in the kitchen. Start by mixing together a box of white cake mix, champagne, and oil. Add in eggs one at a time, then fold in chopped strawberries. Pour the batter into a greased cake pan and bake for 30-35 minutes, or until a toothpick inserted into the center of the cake comes out clean. Let the cake cool completely before frosting with a simple buttercream frosting made with powdered sugar, butter, and champagne. Garnish with fresh strawberries and serve!
