These fun cupcakes are so easy to make. Just mix 1 box of cake batter evenly into 4 different Ziploc® containers. Add food coloring to each bowl to make red, blue, yellow and green. Spoon the different colors of cake batter right inside of a Ziploc® bag. Pipe and layer each color into muffin tins. They’re the perfect dessert for birthday or end-of-school parties. Just finish with frosting, sprinkles, and our Angry Birds cupcake toppers. See The Angry Birds Movie in theaters May 20th.
