Flag Cake

Make Flag Cake: top a white cake with whipped cream, blueberries, and strawberries for a bright, patriotic dessert.

Ingredients

• 1 White Box Cake Mix (prepared according to the package)
• 1 16-Ounce Container Whipped Topping (thawed)
• 2 Half-Pints Fresh Blueberries
• 2 Cups Fresh Strawberries (hulled and sliced)
• Powdered Sugar (for dusting)

Instructions

Step 1: Bake and Cool the Cake

Preheat and bake the white cake according to the box instructions in a 9x13 metal pan; once baked, remove and allow it to cool completely in the pan until the crumb is set and the top feels room temperature and springy. Take a moment to admire the even, pale golden surface and the fine, tender crumb that will hold the flag decoration — this cooling phase is what keeps your topping from sliding and gives the finished cake a clean, flat canvas.

Step 2: Spread the First Layer of Whipped Topping

Spoon half of the thawed whipped topping onto the cooled cake and spread it into a smooth, even white layer using an offset spatula or the back of a spoon so the surface is silky and matte; keep the edges neat so the stripes later will read crisp against the white field. Refrigerate briefly if the topping softens, keeping the texture glossy-but-stable for decoration.

Step 3: Place the Blueberry Star Field

In the upper left-hand corner of the frosted cake, arrange the fresh blueberries into a tight rectangular star field: a neat, compact cluster, evenly spaced so the deep indigo berries pop against the whipped cream. Press each berry slightly to sink it into the topping so they read as a cohesive blue square rather than loose scattered dots.

Step 4: Lay the Strawberry Red Stripes

Use the hulled, sliced strawberries to create five bold red stripes across the remaining surface of the cake, starting at the top edge and finishing at the bottom. Place the slices in slightly overlapping rows so each stripe reads as a continuous band of vibrant red — the glossy flesh and seeded texture should contrast sharply with the smooth white cream.

Step 5: Pipe the White Whipped Cream Stripes

Fit a piping bag or use a small spoon to pipe the remaining whipped topping into four white stripes in the gaps between the strawberry bands, forming clean, slightly peaked ribbons of cream that alternate with the red. Aim for consistent thickness and soft, cloud-like peaks that hold their shape and create an iconic striped rhythm.

Step 6: Dust, Garnish, and Serve

Lightly dust a whisper of powdered sugar over any exposed berry edges if desired, arrange a few whole strawberries beside the cake for serving, then present immediately so the whipped cream stays pristine and the berries remain glossy and fresh.

Notes

• Chill the cake completely before frosting to prevent slipping
• Pat berries dry to avoid excess moisture on the topping
• Use an offset spatula or the back of a spoon for a smooth finish
• If whipped topping softens, refrigerate the cake briefly before continuing
• For a richer flavor, use stabilized homemade whipped cream instead of store-bought topping
