Make & bake cupcakes
Preheat the oven to 350ºF. Line the cupcake pan with liners.
In a large bowl, combine cake mix, Champagne, egg whites and oil. Beat with an electric mixer on low speed 30 seconds, scraping bowl frequently. Beat at medium speed for 2 minutes.
Fill baking cups 2/3 full with batter.
Bake for 18-20 minutes or until a toothpick inserted in a cupcake’s center comes out clean. Cool cupcakes in the pan on a cooling rack for 5 minutes. Remove from the pan and cool completely on the rack.
