Ingredients:
- 2 ½ cups (300g) all-purpose flour, plus more for dusting
- 1 tablespoon (15g) baking powder
- ½ teaspoon (3g) salt
- 1 cup (226g) unsalted butter, softened, plus more for greasing
- 1 ¾ cups (350g) granulated sugar
- 2 large eggs
- 1 teaspoon (5ml) vanilla extract
- 1 ¼ cups (300ml) whole milk
- Red gel food coloring
- Blue gel food coloring
- 1 cup (226g) unsalted butter, softened
- 4 cups (480g) powdered sugar, sifted
- ¼ cup (60ml) heavy cream
- 1 teaspoon (5ml) vanilla extract
- Pinch of salt
- 1 pint fresh strawberries, hulled and halved
- 1 pint fresh blueberries
- Edible glitter (optional)
Instructions:
- Grease and flour three 8-inch round cake pans. Line the bottoms with parchment paper rounds.
- Whisk together flour, baking powder, and salt in a medium bowl.
- In a separate bowl, cream together softened butter and sugar until light and fluffy.
- Beat in eggs one at a time, then stir in vanilla extract.
- Gradually add the dry ingredients to the wet ingredients, alternating with the milk, beginning and ending with the dry ingredients. Mix until just combined.
- Divide the batter evenly into three bowls. Tint one bowl red, one bowl blue, and leave one bowl plain.
- Pour each batter into a prepared cake pan. Bake at 350°F (175°C) for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cakes cool in the pans for 10 minutes, then invert them onto a wire rack to cool completely.
- In a large bowl, beat softened butter until smooth and creamy. Gradually add sifted powdered sugar, beating on low speed until combined. Add heavy cream, vanilla extract, and salt. Beat on medium-high speed until light and fluffy.
- Place one cake layer on a serving plate or cake stand. Spread with a layer of buttercream frosting. Repeat with the second and third cake layers.
- Frost the entire cake with buttercream frosting. Use an offset spatula to create a smooth finish.
- Arrange strawberries and blueberries on top of the cake in a patriotic pattern. Sprinkle with edible glitter (optional).
- Chill the cake for at least 30 minutes before serving.
