Flag Cake

Make Flag Cake now: decorate a baked cake with whipped topping, blueberries and strawberries to create a patriotic Flag Cake.

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 the Cake

Preheat imagination: bake the white box cake exactly according to the package directions in a 9x13 rectangular pan, then remove and let it cool completely on the painted pine wood surface. The focus here is on getting an even, lightly golden crumb and a flat top — if the top domes a little, trim gently so the decoration will sit level. Cool fully until the sponge is room temperature and the crumb feels springy but settled; a warm cake will make the whipped topping slide, so patience here yields the cleanest final stripes.

Step 2: Apply the First Layer of Whipped Topping

Scoop half of the thawed 16-ounce whipped topping and spread it evenly over the completely cooled cake using a wide offset spatula, working in smooth strokes left-to-right to create a satin, cloud-like surface. The goal is a uniform, thin white canvas: soft peaks smoothed down into an even layer with subtle ridges from the spatula. Keep the offset spatula nearby — it will be the active tool for the next step.

Step 3: Arrange the Fruit Flag Elements

Using fresh blueberries for the blue canton, cluster them tightly in the upper-left corner to form a dense, textured rectangle; press lightly so they nestle into the whipped topping. Slice hulled strawberries and, for a festive touch, shape many slices into small heart-like ovals. Arrange those slices into five bold red stripes running horizontally across the remaining cake, starting at the top edge and finishing at the bottom edge, leaving even spaces between stripes for the white piped separators. Hold back the remaining whipped topping for piping.

Step 4: Pipe the White Stripes and Serve

Fill a pastry bag or zip-top with the reserved whipped topping and pipe four clean, ruffled white stripes between the strawberry rows, creating crisp contrast and light volume against the red. Dust very lightly with powdered sugar for a soft, celebratory sheen. Transfer the rectangular cake to a sleek white rectangular serving dish if desired, keep the dish rectangular and geometrically consistent with the original 9x13 shape, and present immediately so the berries remain glossy and the whipped peaks hold their texture.

Notes

• Chill the cake completely before applying whipped topping to prevent sliding.
• Thaw and drain frozen berries before using to avoid excess moisture.
• Trim any dome from the cake top for a flat surface and neater decoration.
• Use an offset spatula for smooth topping and a pastry bag or zip-top for clean white stripes.
• Assemble the fruit stripes just before serving for the freshest look.
