For the Cake

  • ½ cup (120 ml) whole milk
  • ⅓ cup (75 g) butter (melted)
  • 2 large eggs (room temperature)
  • blue food coloring
  • red food coloring

For the Buttercream Frosting

  • 1 cup (227 g) butter (room temperature)
  • 1 cup (190 g) vegetable shortening
  • 2 lbs (907 g) confectioners’ sugar
  • 1½ tbsps. (22 ml) water
  • 1½ tsps (7 ml) vanilla extract
  • red food coloring
  • blue food coloring
  • 1 tbsp red, white and blue sprinkles (optional)

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 ensure the cake releases easily after baking.

Step 2: Prepare the Cake Batter

In a large mixing bowl, combine:
1. The cake mix,
2. Full-fat sour cream,
3. Whole milk,
4. Melted butter,
5. Eggs.

Beat on high speed for about 4 minutes until smooth.

Step 3: Add Color Swirls

Pour the batter into the prepared pan and spread it evenly across the surface.
– Add drops of blue food coloring across the top.
– Use the back of a spoon to swirl gently.
– Repeat with red food coloring without overmixing; aim to keep distinct colors.

Step 4: Bake the Cake

Bake in the preheated oven for 25–28 minutes, or until a toothpick inserted in the center comes out clean. Allow the cake to cool completely before frosting.

Step 5: Make the Buttercream Frosting

While cooling:
1. In another mixing bowl, beat together room temperature butter and vegetable shortening on medium-high until fluffy.
2. Gradually add confectioners’ sugar while reducing mixer speed to low.
3. Once combined, add water and vanilla extract. Beat on high for an additional 4–6 minutes until smooth.

Step 6: Color Your Frosting

Divide the frosting into three bowls:
– Tint one bowl red,
– One bowl blue,
– Leave one bowl white.

Transfer each colored frosting into separate piping bags fitted with a large star tip.

Step 7: Decorate Your Cake

Flip or transfer the cooled cake onto a tray or keep it in the pan. Begin decorating:
1. Pipe a blue rectangle in the top left corner using blue frosting stars—four rows about 5 inches long by 3 inches tall.
2. Alternate piping red and white stars in stripes across the remaining area of the cake, starting from red at the top.
3. Optionally sprinkle red, white, and blue sprinkles over as finishing touches.

Now you’re ready to serve this stunning Buttercream Flag Cake at your next gathering! Enjoy this festive dessert that captures both flavor and fun!

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

To achieve the best results with your Buttercream Flag Cake, consider these helpful tips. They will guide you in perfecting both the taste and appearance of this festive dessert.

  • Use Room Temperature Ingredients: Ensure that your butter, eggs, and milk are at room temperature before mixing. This helps create a smoother batter and fluffier cake.

  • Avoid Overmixing: When combining ingredients, mix just until incorporated. Overmixing can lead to a dense texture instead of light and fluffy.

  • Cool Completely: Allow the cake to cool completely before frosting. This prevents melting the buttercream and ensures clean layers.

  • Piping Technique: Practice piping stars on parchment paper before decorating the cake. This will help you get comfortable with the technique for more consistent results on the actual cake.

  3. Potato Salad: Creamy potato salad with herbs provides comfort food vibes that balance well with lighter desserts like your Buttercream Flag Cake.

  4. Fresh Fruit Salad: A medley of seasonal fruits not only looks beautiful but also brings freshness to each bite alongside your rich dessert.

  5. Corn on the Cob: Grilled or boiled corn on the cob is a summer staple that pairs wonderfully with sweet treats, making it an ideal side dish for outdoor gatherings.

  6. Deviled Eggs: Simple yet flavorful deviled eggs offer savory bites that contrast nicely with the sweetness of your cake, appealing to varied tastes at your party.

Common Mistakes to Avoid

Making a Buttercream Flag Cake can be simple, but there are some common pitfalls that can affect your results. Here are some mistakes to watch out for:

  • Neglecting Room Temperature Ingredients: Using cold eggs or butter can lead to a lumpy batter. Always ensure your butter and eggs are at room temperature for better mixing.

  • Overmixing the Batter: Mixing the batter too long can result in a dense cake. Mix just until ingredients are combined to keep it light and fluffy.

  • Ignoring Oven Calibration: Every oven is different, and yours may not be at the right temperature. Use an oven thermometer to make sure it’s accurate before baking.

  • Not Cooling the Cake Completely: Frosting a warm cake can lead to melting frosting. Allow the cake to cool completely on a wire rack before decorating.

  • Using Too Much Food Coloring: Overdoing the food coloring can alter the taste and texture of your cake. Use just enough for vibrant colors without affecting the flavor.
