Ingredients
  

For the Cake
  • 2 cups all-purpose flour This forms the base of your cake.
  • 1.5 cups granulated sugar For that perfect sweetness.
  • 0.5 cup unsalted butter Adds richness to the cake.
  • 1 cup whole milk For moisture and tenderness.
  • 3.5 teaspoons baking powder Helps the cake rise beautifully.
  • 1 teaspoon vanilla extract A must for flavor!
  • 0.5 teaspoon salt Balances the sweetness.
  • 4 large eggs For structure and richness.
For the Frosting
  • 1 cup unsalted butter For a creamy frosting.
  • 4 cups powdered sugar Sweet and fluffy frosting.
  • 1 teaspoon vanilla extract More flavor!
  • 2-4 tbsp heavy cream or milk For the right consistency.
  • 1 cup blueberries For the blue section of the flag.
  • 3 cups strawberries sliced for the red stripes.
  • 1 cup raspberries optional for extra decoration.

Equipment

  • 9×13 inch baking pan
  • Large Mixing Bowl
  • Wire rack

Method
 

  1. Step 1: Preheat your oven to 350°F (175°C). Grease and flour a 9x13-inch baking pan. In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract. In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, alternating with the milk. Mix until just combined. Pour the batter into the prepared baking pan and smooth the top. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely in the pan on a wire rack.
  2. Step 2: In a large mixing bowl, beat the softened butter until creamy. Gradually add the powdered sugar and mix until combined. Add the vanilla extract and 2 tablespoons of heavy cream or milk. Beat until smooth and fluffy. Add more cream if needed for desired consistency.
  3. Step 3: Once the cake is completely cool, spread a generous layer of frosting over the top. Arrange the blueberries in the top left corner to create the blue section of the flag. Create stripes with the sliced strawberries across the top, leaving space for the blueberries. If using raspberries, fill in any gaps or decorate around the edges.
  4. Step 4: Slice into squares and serve at your celebration. Enjoy your delicious flag cake!
