Ingredients

Scale
  • Champagne Cake
    • 2 & 2/3 cup cake flour (420 g)
    • 1 & 1/2 cup granulated sugar
    • 1 tsp salt
    • 1 tsp baking powder
    • 3/4 tsp baking soda
    • 1 cup neutral oil (vegetable oil)
    • 3 large eggs + 2 egg whites (room temperature)
    • 1 tsp vanilla extract
    • 1 & 1/2 cup dry champagne
  • Elderflower Simple Syrup
    • 1/4 cup water
    • 1/4 cup sugar
    • 2 Tbsp elderflower liqueur (St. Germain)
  • Elderflower Frosting
    • 1/2 cup + 3 Tbsp unsalted butter (room temperature)
    • 5 cups powdered sugar, sifted
    • 1/3 cup elderflower liqueur (St. Germain)
    • 3 Tbsp heavy whipping cream
    • 1/4 tsp salt
    • 1/2 cup strawberry preserves

Instructions

  1. Preheat oven to 350°F. Spray and line three 8-inch cake pans with parchment.
  2. Sift together flour, sugar, salt, baking powder, and baking soda.
  3. Whisk together champagne, oil, eggs, and vanilla in a separate bowl.
  4. Fold wet ingredients into dry ingredients until just combined; divide batter evenly among pans.
  5. Bake 22 minutes or until a toothpick comes out clean; cool completely in pans.
  6. Meanwhile, make simple syrup: heat water and sugar until dissolved, remove from heat, stir in elderflower liqueur; set aside.
  7. Make frosting: beat butter until creamy, add powdered sugar, elderflower liqueur, and salt on low speed; add cream one tablespoon at a time until desired consistency, then beat on high 2 minutes.
  8. Level cake domes with a serrated knife; brush each layer with simple syrup.
  9. Assemble: pipe a frosting dam around edge of first layer, fill with half the strawberry preserves; repeat with second layer; top with third.
  10. Apply a thin crumb coat, chill 1 hour; finish frosting top and sides, serve at room temperature; refrigerate leftovers up to 3 days.

Notes

  • If you don’t have cake flour, use a substitute of all-purpose flour and cornstarch.
  • For crumb-coating technique, watch a video tutorial (e.g., mWItHfoJe_A on YouTube).
