Champagne Cupcakes

cooking spray

1 (18.25 ounce) package white cake mix

1 ¼ cups Champagne or other sparkling white wine at room temperature

⅓ cup vegetable oil

3 eggs

½ cup butter, softened

4 cups confectioners sugar

¼ cup Champagne or other sparkling white wine at room temperature

1 teaspoon vanilla extract

Preheat oven to 350 degrees F (175 degrees C).

Spray 24 muffin cups with cooking spray.

Mix cake mix and 1 1/4 cup Champagne in a large mixing bowl; stir in vegetable oil and eggs. Beat batter with an electric mixer on medium speed for 2 minutes.

Pour batter into the prepared muffin cups, filling them 3/4 full.

Bake cupcakes in the preheated oven until a toothpick inserted into the middle of a cupcake comes out clean, about 20 minutes.

Cool cupcakes in pans for 10 minutes before removing to finish cooling, about 30 more minutes.

Mix butter, 1 cup confectioners sugar, 1/4 cup Champagne, and vanilla extract in a bowl. Stir in remaining confectioners sugar, 1 cup at a time, until frosting is smooth and creamy. Spread on cooled cupcakes.
