Rainbow Cupcakes

Hey! Emlyn present.

It’s a cozy Saturday night. You’re tired of cleaning all day and want to make something sweet before having to continue. What do you make?


(I’m in such a cupcake rut omg help me out)

Nah, in reality these were very easy to make. And they came out ~*gorgeous*~


I modified the recipe to make a smaller amount. My tiny family could never eat the 24 the original recipe calls for :P


  • 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


  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. 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. 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. 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.


If you’d like, you can mix the primary colors together if you wish for a different scale. I just used the basics :)

I added basic Betty Crocker icing (the decorators kind) because 1. it was all we had and 2. we have no more butter so I couldn’t whip up any buttercream :( Add your favorite, though!

When someone eats one (I made these for others) I’ll try to get a picture of the inside for you guys.

EDIT: My mom ate one :3 here’s the photo.
