  • Total Time: 1 hour 15 minutes
  • Yield: 8 servings

Ingredients

  • Vanilla Cake Base:
    • 230 grams (1 cup or 2 sticks) unsalted butter, room temperature
    • 200 grams (1 cup) caster sugar or granulated sugar
    • 2 teaspoons vanilla extract
    • 3 large eggs, room temperature
    • 315 grams (2 and 1/4 cups) plain flour or all purpose flour  
    • 3 teaspoons baking powder
    • 1/4 teaspoon salt
    • 240 ml (1 cup) full fat or whole milk
    • 2 tablespoons full fat sour cream
  • Strawberry Layer:
    • 1 teaspoon strawberry extract
    • Pink food gel or food coloring
  • Chocolate Layer:
    • 1 tablespoon cocoa powder, sifted
    • 1 tablespoon milk
  • Vanilla Buttercream:
    • 230 grams (1 cup or 2 sticks) butter, room temperature
    • 2 teaspoons vanilla extract or vanilla bean paste
    • 625 grams (5 cups) icing sugar or powdered sugar
    • 3–4 tablespoons full fat or whole milk, room temperature
  • To Decorate (Optional):
    • Assorted candy and chocolate*

Instructions

  • Prepare for Baking: Preheat your oven to 180°C (350°F) standard / 160°C (320°F) fan-forced. Grease and line three 6-inch round baking pans.
  • Cream Butter and Sugar: In a large mixing bowl, beat together the room temperature butter, sugar, and vanilla extract with an electric mixer until the mixture is light, smooth, and creamy.
  • Add Eggs: Incorporate the eggs one at a time, beating well after each addition.
  • Combine Dry and Wet Ingredients: Sift in the flour, baking powder, and salt. Add the milk and sour cream. Beat on a low speed just until the ingredients are combined. Don’t overmix.
  • Divide the Batter: Carefully divide the cake batter evenly into three separate bowls. For best accuracy, use a kitchen scale to weigh the batter.
  • Flavor the Layers: To one bowl, add the strawberry extract and a few drops of pink food gel and stir. To another, add the sifted cocoa powder and the extra milk and stir until smooth. Leave the final batter as is (vanilla).
  • Pour and Bake: Pour each flavored batter into your three prepared baking pans. Bake for approximately 30 minutes or until a skewer inserted in the middle comes out clean.
  • Cool the Cakes: Carefully remove the cakes and set on a wire rack to cool completely.
  • Make the Buttercream: In a clean bowl, beat the room temperature butter with an electric mixer until smooth and creamy. Add the vanilla. Gradually add the icing sugar, one cup at a time, adding a tablespoon of milk as needed, until the frosting is smooth and creamy.
  • Assemble the Cake: Once the cakes are completely cool, level the tops if necessary. Place one cake layer on a cake board. Cover the top with buttercream. Place the second cake on top and cover with buttercream. Add the third cake on top.
  • Frost the Cake: Cover the entire cake, top and sides, with the remaining buttercream. Use a cake scraper to smooth the sides, if desired.
  • Decorate! Cover the top of the cake with your favorite candy and chocolates.

Notes

  • I used pieces of milk chocolate, white chocolate, Smarties, mini M&M’s and Freckles. Use your preferred candy or chocolate.
  • Ensure butter is at room temperature for both the cake batter and buttercream for best results.
  • Avoid overmixing the cake batter once dry and wet ingredients are added.
  • Weighing the batter helps ensure even cake layers.
  • Cool cakes completely before frosting.
