Can I make the cake from scratch instead of using a mix?

Absolutely! My favorite homemade version uses 2 cups flour, 1 1/2 cups sugar, 1/2 cup butter, 3 eggs, and 1 cup buttermilk. Just bake at 350°F until golden—about 30-35 minutes. The box mix is my go-to for speed, but scratch cakes have that special homemade taste.

How do I stop the berries from bleeding into the whipped cream?

The secret is in the prep: Pat those berries bone-dry with paper towels before arranging them. I also chill the frosted cake for 15 minutes before adding berries—it creates a firmer surface. If you're really worried, a thin layer of piping gel under the berries acts as a moisture barrier.

Can I make this flag cake ahead of time?

You can bake the cake 1 day ahead—just wrap it tightly once cooled. Wait to frost and decorate until 3-4 hours before serving. The berries stay freshest this way. Leftovers keep covered in the fridge for 2 days max.

What if I can't find fresh blueberries?

No panic! Blackberries work in a pinch (though they're darker), or get creative with star-shaped cookie cutters on sliced bananas. One year I used star sprinkles when blueberries were scarce—still got rave reviews!

Is there a way to make this cake less sweet?

Try reducing the powdered sugar in the whipped cream to 2 tablespoons, or use slightly tart berries like raspberries for the stripes. The natural fruit acidity balances the sweetness beautifully.
