Ingredients

Scale
  • 2 ½ cups (312 g) all-purpose flour, sifted
  • 2 ½ teaspoons baking powder
  • ½ teaspoon salt
  • 1 cup (227 g) unsalted butter, softened
  • 1 ¾ cups (350 g) granulated sugar
  • 4 large eggs, room temperature
  • 1 cup (240 ml) whole milk
  • 2 teaspoons pure vanilla extract
  • ½ cup (about 85 g) pastel rainbow sprinkles
  • For the Lavender Frosting:
  • 1 cup (227 g) unsalted butter, softened
  • 4 cups (480 g) powdered sugar, sifted
  • 23 tablespoons (3045 ml) heavy cream
  • 1 teaspoon pure vanilla extract
  • ½ teaspoon lavender extract
  • Optional: a few drops of purple gel food coloring

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour two 8-inch (20 cm) round cake pans or line with parchment paper.
  2. In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
  3. In a large bowl, beat softened butter and granulated sugar on medium speed until light and fluffy, about 3-5 minutes.
  4. Beat in eggs one at a time, fully incorporating each before adding the next. Scrape down sides as needed.
  5. Alternate adding flour mixture and milk to butter mixture, starting and ending with flour. Mix gently on low speed just until combined.
  6. Fold in pastel sprinkles gently using a rubber spatula to avoid color bleeding.
  7. Divide batter evenly between prepared pans and smooth tops with a spatula.
  8. Bake for 28-32 minutes or until a toothpick inserted in the center comes out clean.
  9. Cool cakes in pans for 10 minutes, then turn out onto cooling racks until completely cool.
  10. For frosting, beat softened butter on medium speed until smooth and creamy, about 2 minutes.
  11. Gradually add powdered sugar, one cup at a time, beating well after each addition.
  12. Add heavy cream, vanilla extract, and lavender extract. Beat on high for 3-4 minutes until light and fluffy.
  13. Add purple gel food coloring if using and mix until evenly tinted.
  14. Place one cake layer on serving plate and spread a generous layer of lavender frosting on top.
  15. Place second cake layer over and spread frosting evenly over top and sides using an offset spatula.
  16. If frosting is too soft, chill cake in fridge for 15 minutes before serving.

Notes

Do not overmix the batter to keep the cake tender. Fold sprinkles in gently to prevent color bleeding. Use room temperature ingredients for best texture. Cool cakes completely before frosting to avoid melting. For stronger lavender flavor, add extract gradually. The cake can be made gluten-free by using a gluten-free flour blend and dairy-free by substituting milk and butter accordingly.
