Ingredients

Scale
  • 2 ½ cups (315g) all-purpose flour, sifted
  • 2 ½ teaspoons baking powder
  • ½ teaspoon salt
  • ½ cup (115g) unsalted butter, softened
  • 1 ½ cups (300g) granulated sugar
  • 4 large eggs, room temperature
  • ¾ cup (180ml) champagne, chilled (dry or brut recommended)
  • ½ cup (120ml) whole milk, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 cup (230g) unsalted butter, softened (for frosting)
  • 4 cups (480g) powdered sugar, sifted (for frosting)
  • 1 ½ teaspoons vanilla extract (for frosting)
  • 23 tablespoons heavy cream (for frosting)
  • Pinch of salt (for frosting)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans or line them with parchment paper.
  2. In a medium bowl, whisk together sifted all-purpose flour, baking powder, and salt. Set aside.
  3. In a large bowl, beat softened unsalted butter with granulated sugar on medium speed until light and fluffy, about 3 to 5 minutes.
  4. Add eggs one at a time, beating well after each addition.
  5. In a small bowl, combine chilled champagne, whole milk, and vanilla extract.
  6. With mixer on low, alternately add the dry ingredients in three parts and the champagne-milk mixture in two parts, starting and ending with dry ingredients. Mix just until combined.
  7. Divide batter evenly between prepared pans (about 600g batter per pan).
  8. Bake on middle rack for 28-32 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  9. Cool cakes in pans for 10 minutes, then run a knife around edges and transfer to wire racks to cool completely.
  10. For frosting, beat softened butter on medium speed until creamy, about 2 minutes.
  11. Gradually add powdered sugar on low speed until combined.
  12. Add vanilla extract, pinch of salt, and heavy cream; increase speed to medium-high and whip until light and fluffy, about 3-5 minutes. Adjust cream for desired consistency.
  13. Assemble cake by placing one layer on serving plate, spreading a thick layer of buttercream, topping with second layer, and frosting top and sides evenly.
  14. Optional: decorate with edible glitter or fresh berries.

Notes

Use room temperature ingredients for best results. Do not overmix batter to keep cake light and fluffy. Use dry or brut champagne for balanced flavor. Let cakes cool completely before frosting to prevent sliding. Adjust frosting consistency with heavy cream or chilling as needed. For dairy-free or vegan versions, substitute ingredients accordingly.
