Rainbow cupcakes are a colorful and fun option for a kids' birthday party. To make these vibrant treats, prepare a basic vanilla cupcake batter and divide it into separate bowls. Add food coloring to each bowl to create different colors of batter. Layer the colored batter in cupcake liners and bake until a toothpick inserted into the center comes out clean. Once the cupcakes have cooled, frost them with vanilla buttercream and top with rainbow sprinkles. These cupcakes are sure to be a hit with kids of all ages.
