Camouflage cupcake sandwiches from Life is Sweets pays tribute to the United States military. French vanilla cake batter is divided into four separate bowls, colored black, army green, beige, and brown. To get the camouflage effect, carefully spoon each color into a whoopie pie pan. A whoopie pie pan is more shallow compared to a cupcake tin, creating thin layers of cake ideal for making sandwiches. While the cakes are cooling, make the buttercream frosting (you can dye it army cream or choose to leave it plain). Camouflage cupcake sandwiches are perfect to bake for anyone in the military or any army themed event.
