1 (18.25 ounce) package white cake mix1 1/4 cups water1/3 cup vegetable oil3 egg whites8 drops red food coloring2 drops raspberry candy oil

Instructions:
Preheat an oven to 350 degrees F (175 degrees C). Line a standard muffin tin with paper cupcake liners. Beat the cake mix, water, vegetable oil, and egg whites together on low speed for 30 seconds, then on medium for 2 minutes, until smooth. Fill cupcake liners 1/3 full with white batter; set aside. Stir 4 drops of red food coloring into the remaining bowl of batter to make the batter pink, stir in the raspberry oil. Pour 1/3 of pink batter into a resealable plastic bag and set aside. Mix more food coloring into the remaining bowl of pink batter until it is an orange/red color and pour the batter into a resealable plastic bag. Cut a corner off the bag, stick the open tip into the center of each cup of white batter and squeeze in about two tablespoons of red batter. Cut the corner off the bag with the pink batter, stick the open tip into the center of the red batter and squeeze about 1 tablespoon pink batter into each cup. Bake the layered cupcakes in the preheated oven until a toothpick inserted into the center comes out clean, 15 to 20 minutes. Cool completely before frosting.
