Instructions

Place pink champagne in a small saucepan over medium heat and simmer until reduced to approximately 6 tablespoons; set aside to cool completely for the frosting.
Preheat oven to 350°F (175°C) and prepare two 8-inch round cake pans with parchment paper and grease.
In a large mixing bowl, beat the softened butter until creamy, then add sugar, oil, and vanilla, whipping until light and fluffy.
Whisk together flour, baking powder, and salt in a separate bowl.
Alternate adding the flour mixture and the liquids (buttermilk and 1/2 cup of unreduced champagne) to the butter mixture, beginning and ending with the flour while mixing on low speed.
In a separate grease-free bowl, whip the egg whites until stiff peaks form, then gently fold them into the cake batter using a rubber spatula until just combined.
Divide the batter evenly between the prepared pans and bake for 25–28 minutes or until a tester comes out clean.
Once the cakes are completely cooled, beat the remaining butter with powdered sugar and the cooled champagne reduction to create a smooth buttercream, then frost the layers as desired.

Notes

To ensure the most delicate crumb, avoid over-mixing the batter after adding the flour. For a professional finish, use a rotating cake stand when applying the champagne buttercream to achieve perfectly smooth sides and sharp edges.
