I have seen recipes for a rainbow cake floating around and thought I would give it a try with red, white and blue. I mixed up a regular white cake mix, then separated the batter into three bowls, adding blue food coloring to one bowl and red to another.
Using a 13x9 inch pan, I poured in the white batter first, then layered on the red, followed by the blue (in a half-hazard way, as you can see). Then, using a toothpick, I swirled them together a bit. I wasn't sure how this would look after it was baked and cut into, but it was worth a try. I probably should have put the red down first, then the white, followed by the blue. I was too anxious to get it in the oven and see what it would look like!
After the cake has cooled completely, spread one tub of whipped topping on top. Add blueberries and sliced strawberries to make the flag design.
When it was time for dessert, this is what it looked like - pretty cool! Just enough red and blue to not look too scary to eat it. Next time I might swirl it around a little more or try making stripes instead. The blue cake kinda looked a little greenish where the top of the cake turned golden brown. But it tasted delicious!
