A festive and easy 4th of July dessert featuring moist yellow cake squares layered with whipped cream and fresh strawberries and blueberries arranged in a patriotic flag pattern.
Use very cold heavy cream for best whipping results. Chill the cake completely before assembling to prevent whipped cream from melting. Use a serrated knife to cut cake squares cleanly. Refrigerate assembled cake for at least 1 hour before serving. For gluten-free option, substitute cake mix with gluten-free mix. For dairy-free, use coconut whipped cream and dairy-free cake mix.
