Ingredients

Scale
  • 2 ½ cups (312g) all-purpose flour, sifted
  • 2 ½ tsp baking powder
  • ½ tsp baking soda
  • ½ tsp fine sea salt
  • 1 cup (226g) unsalted butter, softened
  • 1 ¾ cups (350g) granulated sugar
  • 4 large eggs, room temperature
  • 1 tbsp culinary dried lavender buds (food-grade)
  • 1 tbsp lemon zest (from about 2 large lemons)
  • 1 cup (240ml) buttermilk, room temperature
  • ¼ cup (60ml) fresh lemon juice
  • 1 ½ cups (340g) mascarpone cheese, chilled
  • ½ cup (120ml) heavy cream, cold
  • ¼ cup (85g) honey
  • 1 tsp vanilla extract
  • Optional: a pinch of salt

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour two 8-inch cake pans or line with parchment paper.
  2. In a medium bowl, sift together flour, baking powder, baking soda, salt, and dried lavender buds. Set aside.
  3. In a large bowl, beat softened butter and sugar on medium-high speed until light and fluffy, about 3-4 minutes.
  4. Beat in eggs one at a time, fully incorporating each before adding the next. Scrape down bowl sides as needed.
  5. Stir lemon zest and lemon juice into buttermilk. Add this mixture alternately with dry ingredients to the batter, beginning and ending with flour mixture. Mix on low speed until just combined.
  6. Divide batter evenly between prepared pans and smooth tops. Tap pans gently to release air bubbles.
  7. Bake for 28-33 minutes or until a toothpick inserted in the center comes out clean and cakes spring back when pressed.
  8. Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely.
  9. In a chilled bowl, whip mascarpone cheese with heavy cream, honey, vanilla extract, and a pinch of salt until soft peaks form. Avoid overwhipping.
  10. Place one cake layer on a serving plate. Spread a generous layer of frosting over the top. Repeat with second layer and frost the outside smoothly or with rustic swirls.
  11. Refrigerate cake for at least 30 minutes before serving to let flavors meld and frosting set.
