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.


  • 1 box vanilla cake mix (plus eggs, water, and oil or butter, as called for on the box)

  • 1 (8-ounce) package cream cheese, softened

  • 1 (8-ounce) container whipped topping, frozen, slightly thawed

  • 3 tablespoons confectioners' sugar

  • 1 pint blueberries

  • 1 to 2 pints raspberries

  5. Place cake in the freezer while you prepare frosting (this makes the flag cake easier to frost).
