Ingredients

Scale

Cake

  • 1½ sticks unsalted butter, softened
  • 1½ cups sugar
  • 2 whole eggs
  • 4 egg yolks
  • 2 teaspoons vanilla extract
  • 3 cups flour
  • 4 teaspoons baking powder
  • 1 tablespoon dried lavender (crushed with fingers)
  • ¾ teaspoon salt
  • 1¼ cups buttermilk (or regular milk as substitute)
  • 6 ounces white chocolate

Lavender Simple Syrup

  • ⅓ cup sugar
  • ⅓ cup water
  • 2 tablespoons dried lavender

Buttercream Frosting

  • ½ cup unsalted butter, softened
  • 23 cups powdered sugar
  • 2 tablespoons lavender simple syrup
  • 1 teaspoon vanilla extract

Instructions

  1. Melt the White Chocolate: Using a double boiler, fill the bottom pot with 1-2 inches of water and bring it to a boil. Turn off the heat, place broken white chocolate pieces into the top pot, and let them melt gently while you prepare the rest of the cake.
  2. Make Lavender Simple Syrup: In a small saucepan, combine ⅓ cup sugar and ⅓ cup water. Bring to a boil while whisking constantly until the sugar dissolves completely. Remove from heat, add 2 tablespoons dried lavender, and allow the mixture to steep to infuse the floral flavor as you continue with the cake.
  3. Prepare the Cake Batter: In a medium bowl, whisk together 3 cups flour, 4 teaspoons baking powder, 1 tablespoon crushed dried lavender, and ¾ teaspoon salt to combine evenly. In a large bowl, cream 1-½ sticks softened butter with 1-½ cups sugar until light and fluffy. Beat in 2 whole eggs, 4 egg yolks, 2 teaspoons vanilla extract, and the melted white chocolate thoroughly. Alternately add the dry flour mixture and 1-¼ cups buttermilk to the butter mixture, mixing until just combined.
  4. Bake the Cake: Divide the batter evenly among three prepared 8-inch cake pans. Bake in a preheated oven at 350ºF (175ºC) for about 20 minutes, or until the cakes start to pull away from the pan sides and a toothpick inserted in the center comes out clean. Remove from oven and allow to cool slightly.
  5. Make the Buttercream Frosting: In a mixing bowl, beat ½ cup softened butter with 2-3 cups powdered sugar, 1 teaspoon vanilla extract, and 2 tablespoons lavender simple syrup until the frosting is light and fluffy. Adjust the powdered sugar or syrup amount to reach your desired consistency.
  6. Assemble the Cake: Using a fork, poke holes all over the warm cake layers. Spoon the strained lavender simple syrup evenly over each layer, allowing the syrup to soak in. Once soaked and cooled, frost the cake layers as desired with the lavender buttercream. Serve and enjoy your fragrant, elegant vanilla lavender cake!

Notes

  • You can substitute regular milk for buttermilk if necessary, but buttermilk yields a more tender crumb.
  • Using a double boiler prevents white chocolate from burning or seizing while melting.
  • Crushing the dried lavender with your fingers before adding releases more flavor.
  • Allow the lavender simple syrup to cool and strain out the lavender to prevent a gritty texture in the cake and frosting.
  • Adjust the lavender simple syrup in the frosting to taste; too much can become overpowering.
  • Ensure cakes are slightly warm before adding syrup to help absorb moisture better.
  • If you prefer a stronger floral note, you can infuse the buttermilk with dried lavender beforehand by warming and steeping the lavender, then cooling before use.
