Your friends will be impressed by this patriotic dessert recipe for Memorial Day or the Fourth of July. This flag cake starts with a cake mix, so it's easy to make, but of course, you can always substitute your favorite homemade cake recipe. It is then topped with a simple whipped cream frosting and decorated with berries. It's best to use fresh blueberries and raspberries; otherwise, the juice from frozen berries will create a red and blue mess.

If using a cake mix, make sure to have the necessary ingredients on hand. Most brands call for three eggs and water, as well as either butter (1/3 to 1/2 cup) or 1/2 cup vegetable oil. Don't worry about making a flag with exactly the right number of stripes; just create as many red stripes as will fit—it's the look you're going after.

“This cake recipe is perfect for July 4th or any patriotic themed cookout. It’s simple to make and can turn anyone into a confident baker. Customize the cake however you want, and even use different berries for a new design if you prefer. Make sure the cake is fully cooled before you begin frosting” —Tracy Wilk

Recipe Variations

  • Virtually any kind of cake mix or sheet cake recipe will work for this recipe. Try a chocolate cake for a chocolate and berries combo, a yellow butter cake for a richer flavor, or a sprinkles cake for a fun, fireworks-like surprise.
  • You can swap the raspberries for capped, sliced strawberries. Overlap them in a line to make the stripes.
  • For a thicker, richer icing, try using this cream cheese buttercream.
