• 1¾ cups granulated sugar
• 4 large eggs
• 2 teaspoons vanilla extract
• 1 cup buttermilk

Cream Cheese Frosting

• 8 ounces cream cheese, softened
• ½ cup unsalted butter, softened
• 4 cups powdered sugar
• 2 teaspoons vanilla extract
• 2–3 tablespoons heavy cream or milk

Flag Decoration

• 1½ cups fresh blueberries
• 3 cups fresh strawberries, hulled and sliced
• Fresh raspberries (optional)
• Fresh mint leaves (optional, for garnish)

Equipment Needed

• 9×13-inch baking pan
• Mixing bowls
• Electric mixer
• Offset spatula
• Cooling rack

Instructions

Step 1: Prepare the Oven

Preheat the oven to 350°F (175°C).

Grease and line a 9×13-inch baking pan with parchment paper.

Step 2: Mix the Dry Ingredients

In a bowl whisk together:

• Flour
• Baking powder
• Baking soda
• Salt

Set aside.

Step 3: Make the Batter

Beat the butter and sugar until light and fluffy, about 3–4 minutes.

Add the eggs one at a time, mixing well after each addition.

Mix in the vanilla extract.

Alternately add the dry ingredients and buttermilk, beginning and ending with the dry ingredients.

Mix until just combined.

Step 4: Bake

Pour the batter into the prepared pan and smooth the top.

Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.

Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.

Step 5: Prepare the Frosting

Beat together:

• Cream cheese
• Butter

until smooth and creamy.

Gradually beat in the powdered sugar.

Mix in:

• Vanilla extract
• Heavy cream

Continue beating until light and fluffy.

Step 6: Frost the Cake

Spread the frosting evenly over the cooled cake using an offset spatula.

Step 7: Create the Flag Design

Blue Field

Arrange the blueberries in the upper left corner of the cake to create the “stars” section.

Red Stripes

Create horizontal rows of sliced strawberries across the remaining cake, leaving equal-width white frosting stripes between each row.

Step 8: Chill

Refrigerate the cake for 20–30 minutes before slicing to help the frosting set.

Step 9: Serve

Slice into squares and serve chilled or at cool room temperature.

Tips for the Perfect Flag Cake

Dry the Fruit

Pat the blueberries and strawberries dry with paper towels so they don’t release excess moisture onto the frosting.

Cool Completely

Never frost a warm cake, or the frosting will melt.

Use Fresh Fruit

Fresh berries provide the brightest color and best texture.

Decorate Just Before Serving

This keeps the fruit looking fresh and vibrant.

Coconut Flag Cake
