Cupcakes

Ingredients

  • 1 box high-quality white cake mix (look for one without pudding already included)
  • ¾ cup dry champagne or prosecco (room temperature)
  • ¼ cup whole milk
  • 4 large egg whites
  • ½ cup melted unsalted butter (instead of oil)
  • ¼ cup neutral oil
  • ⅓ cup sour cream
  • Seeds from 1 vanilla bean (or 2 tsp pure vanilla)
  • Pinch fine salt

Why this works

  • Champagne gives subtle acidity and lightness
  • Butter + oil gives flavor and moisture
  • Egg whites keep it refined and pale
  • Sour cream keeps crumb velvety
Mix all ingredients into a standing mixer starting with the box cake mix. Beat on medium speed for two minutes. Place in cupcake pan with desired cupcake wrappers, fill 1/4 full. Bake in preheated over of 325 degrees for 19-22 min.

Bake

  • 325°F
  • Fill liners ⅔ full
  • 19–22 minutes
  • Cool completely before frosting

Texture goal: tight, tender crumb with flat tops.

Champagne Mascarpone Buttercream

(Less sweet, silkier than standard American buttercream)

  • 1 cup unsalted butter, very soft
  • 8 oz mascarpone, chilled but smooth
  • 3 cups sifted powdered sugar
  • 2 tbsp champagne
  • 1 tsp vanilla
  • Pinch salt
  1. Beat butter alone 3–4 minutes until pale.
  2. Add mascarpone and mix gently (don’t overbeat).
  3. Add sugar gradually.
  4. Finish with champagne + vanilla.

Result: light, smooth, not cloying.
