Rainbow Cupcakes

14 ingredients
4 steps

Ingredients

  • 2 1/2 cups all-purpose flour
  • 2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup milk
  • 1/2 cup vegetable oil
  • 1 teaspoon vanilla extract
  • 1/2 cup butter
  • 1 cup white sugar
  • 3 eggs, room temperature
  • red food coloring
  • blue food coloring
  • green food coloring
  • yellow food coloring

Directions

  1. 1
    Preheat an oven to 350 degrees F (175 degrees C). Line two 12 cup muffin pans with paper baking cups. Stir together the flour, baking powder, baking soda, and salt in a large bowl. Whisk together the milk, vegetable oil, and vanilla extract in a separate bowl until evenly blended; set aside.
  2. 2
    Beat the butter and sugar with an electric mixer in a large bowl until light and fluffy. The mixture should be noticeably lighter in color. Add the room-temperature eggs one at a time, allowing each egg to blend into the butter mixture before adding the next. Pour in the flour mixture alternately with the milk mixture, mixing until just incorporated.
  3. 3
    Divide the cake batter into four separate bowls. Add a few drops of food coloring into one bowl of batter and stir; add more food coloring, if necessary, to reach the desired shade. Repeat with the remaining colors and bowls of batter.
  4. 4
    Using a different spoon for each color batter, spoon a small spoonful of each color into the cupcake liners, until 1/2 to 3/4 full. Do not mix the batter once it is in the cupcake liner. Bake in the preheated oven until a toothpick inserted into the cake comes clean, about 15 to 20 minutes.
