How to Make Buttercream Flag Cake (Simple 4th of July Party Dessert)

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan thoroughly to prevent sticking.

Step 2: Mix the Cake Batter

In a large mixing bowl:
1. Combine the vanilla cake mix, sour cream, whole milk, melted butter, and room temperature eggs.
2. Beat on high speed for about 4 minutes until smooth.

Step 3: Prepare for Baking

Pour the batter into the prepared pan:
1. Spread it evenly across the bottom.
2. Add drops of blue food coloring across the top.
3. Swirl gently with a spoon to create a marbled effect without overmixing.
4. Repeat this process with red food coloring.

Step 4: Bake the Cake

Bake in the preheated oven for 25–28 minutes:
– Check if done by inserting a toothpick into the center; it should come out clean.
– Allow cooling completely before frosting.

Step 5: Make Buttercream Frosting

While waiting for the cake to cool:
1. Beat together the room-temperature butter and vegetable shortening on medium-high speed until fluffy.
2. Gradually add confectioners’ sugar while mixing on low speed until fully incorporated.
3. Add water and vanilla extract; then beat on high speed for about 4–6 minutes until smooth.

Step 6: Color Your Frosting

Divide your frosting into three bowls:
– Tint one bowl red, one blue, and leave one white.
– Transfer each colored frosting into separate piping bags fitted with a large star tip.

Step 7: Decorate Your Cake

Once cooled:
1. Flip the cake onto a tray or leave it in the pan.
2. Pipe a blue rectangle in the top left corner using frosting stars—four rows about 5 inches long and 3 inches tall.
