Why This is the Ultimate Patriotic Party Cake

This isn’t just a cake; it’s a tradition waiting to happen. Here’s why this recipe is a guaranteed hit for any summer celebration.

• The Perfect Sheet Cake Base: This cake is incredible. It’s dense in the best way possible—moist, rich, and sturdy enough to hold up to a generous layer of frosting and fruit without ever being dry. The sour cream in the batter is the secret to its tender texture.
• The Most Luscious Cream Cheese Frosting: This is not your average frosting. It’s a perfect balance of tangy cream cheese and rich butter, and it’s not overly sweet. It’s the ideal creamy complement to the sweet cake and fresh berries.
• A True Showstopper: There is simply no denying the “wow” factor of a beautifully decorated flag cake. It’s an edible centerpiece that looks so impressive and festive on any dessert table.
• Feeds a Crowd: This recipe is made in a large sheet pan, so it’s specifically designed for parties, potlucks, and big family gatherings. (And yes, I’ve included a note on how to halve it if needed!)
• Surprisingly Simple to Decorate: You don’t need to be a professional cake decorator! With a pastry bag and a star tip, creating the neat stripes and starry dollops is fun and incredibly straightforward.

Gather Your Classic Ingredients: What You’ll Need

Let’s gather the simple, high-quality ingredients for this spectacular cake.

For the Cake:

• 18 Tbsp. (2 1/4 sticks) Unsalted Butter, at room temperature
• 3 cups Sugar
• 6 Extra-Large Eggs, at room temperature
• 1 cup Sour Cream (not low-fat), at room temperature
• 1 1/2 tsp. Pure Vanilla Extract
• 3 cups All-Purpose Flour
• 1/3 cup Cornstarch: Helps create a softer, more tender crumb.
• 1 tsp. Kosher Salt
• 1 tsp. Baking Soda

For the Icing & Decoration:

• 1 1/2 lb. (3 (8-oz.) packages) Cream Cheese (not low-fat), at room temperature
• 1 lb. (4 sticks) Unsalted Butter, at room temperature

Crafting Your Flag Cake: Step-by-Step Guide

Let’s break this down into simple, manageable stages: the cake, the frosting, and the fun decoration!

1. Make the Cake Batter: First, preheat your oven to 350°F. Grease and flour a large 17×12.5-inch sheet cake pan. In the bowl of a stand mixer (or a large bowl with a hand mixer), beat the room-temperature butter and sugar together on high speed until light and fluffy, about a minute or two. Add the eggs, two at a time, mixing well after each addition. Mix in the sour cream and vanilla.
2. Combine and Bake: In a separate bowl, sift together the flour, cornstarch, kosher salt, and baking soda. With the mixer on low speed, gradually add the flour mixture to the wet ingredients, mixing until it’s just combined. Don’t overmix! The batter will be very thick. Pour the batter into your prepared pan and use an offset spatula or knife to spread it evenly. Bake for 20 to 30 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool completely in the pan.
3. Whip Up the Cream Cheese Icing: While the cake cools, make the frosting. In the clean bowl of your mixer, whip the room-temperature cream cheese and butter together until combined and smooth. Add the sifted powdered sugar and vanilla and mix until everything is thoroughly combined, scraping down the sides of the bowl once or twice.

1. Decorate Your Flag: Spread about half of the frosting in a smooth, even layer over the cooled cake. Now, let’s create our flag! With a toothpick, gently mark off the square for the stars in the top left corner. Prepare a pastry bag fitted with a large star tip and fill it with some of the remaining icing.
2. Create the Stripes: Starting at the bottom of the cake, pipe two long, straight lines of frosting. Carefully place two neat rows of raspberries right next to each other on the cake. Pipe another two lines of frosting above the raspberries, and repeat the process—frosting stripes, raspberry stripes—until you reach the top.
3. Add the Stars and Stripes: Fill in the square you marked off in the corner with a nice layer of fresh blueberries, placing them close together. Using your pastry bag with the star tip, pipe small, star-like dollops of frosting onto the blueberries. Your beautiful flag is complete!

Wise Tips for the Perfect Cake

• Room Temperature Ingredients are Key: For both the cake and the frosting, having your butter, eggs, sour cream, and cream cheese at room temperature is crucial. It allows the ingredients to emulsify properly, creating a smooth batter and a non-lumpy frosting.
• Don’t Overmix the Batter: Once you add the dry ingredients, mix only until they are just incorporated. Overmixing develops the gluten in the flour and can result in a tough, dry cake.
• Sift Your Powdered Sugar: This is a non-negotiable for smooth cream cheese frosting! Sifting removes any little clumps and guarantees a perfectly silky texture.

Frequently Asked Questions (FAQ) – 4th of July Cake Recipe

1. This recipe seems huge! Can I halve it?
   Yes, absolutely! As the recipe notes, this feeds an army. You can easily halve all the ingredients and bake it in a standard 9×13 inch pan. Just keep an eye on the baking time, as it might be slightly different.
2. Can I use other berries?
   Of course! For the red stripes, you could use sliced strawberries instead of raspberries. Just be sure to pat them dry before placing them on the frosting.
3. Can I make this cake ahead of time?
   Yes! You can bake the cake a day in advance, let it cool completely, and keep it tightly covered at room temperature. You can also make the frosting ahead and store it in an airtight container in the fridge. Just let it soften a bit at room temperature before frosting the cake. For best results, decorate with the fresh berries closer to serving time.
4. I don’t have a pastry bag. How can I decorate it?
   No problem! You can spread the frosting on the cake and use the back of a spoon to create rustic-looking white stripes. Or, you can fill a sturdy zip-top bag with the frosting, snip off a small corner, and use that to pipe your lines and stars.
