Basically, you’re going to be making a 9×11 inch cake (9×13 would work too), covering it with white icing and then garnishing it with blueberries and raspberries so it looks like a flag. Or you could make a star filled in with red, blueberries on the outside…or???

White cake mix (chocolate cake mix works too for all you chocolate lovers)
Vanilla Frosting
1 Pint of Blueberries
1 Pint of Raspberries
2 Pints of Strawberries

Grease & lightly flour bottom of pan. Prepare cake according to package directions. Decorate as you see fit!
