    Step 1

    Hello! Thank you for viewing my Snapguide. I'll be showing you how to make rainbow-layered cupcakes. This should produce 24 cupcakes, requiring approximately 45 minutes prep time, 15 bake time.

    Step 2

    Here we have the supplies and ingredients required (not including the water and optional icing bag + sprinkles).

    Step 3

    First, start with a basic white cake mix to produce the best colors. We'll be mixing together the basic ingredients shown on the box.

    Step 4

    I start by cracking my three eggs and whisking them with a fork in the mixing bowl or small bowl (it will need washed out before use again). You'll want to use a quick, circular motion to add air.

    Step 5

    When you're done whisking the eggs to where they're fully broken down with air bubbles, you'll be combining the cake mix, eggs, 1 1/4 cup water, and 1/3 cup vegetable oil into the large mixing bowl.

    Step 6

    Next, I recommend putting in all the wet ingredients first. This keeps the dry mix from getting caked/stuck to the side. Then, mix with a whisk manually or with an electric mixer until complete.

    Step 7

    Now, you'll separate the batter into your six small bowls as evenly as possible. I have about 5/8 cup in each bowl.

    Step 8

    In this step, you'll add about ten drops of food dye in each bowl. One should be red, orange, yellow, green, blue, and purple, or a combo of certain colors to make ones you don't have the dye for.

    Step 9

    Use your whisk to mix the dye throughout the batter, making sure to rinse it off between colors to prevent mixing them incorrectly.

    Step 10

    After laying the cupcake liners into the pan, use your scoop or spoon to pour a thin layer of the red or purple batter into each cup. Pour it into the center of the cup.

    Step 11

    You'll want to divide it as evenly as possible among them all so use small scoops, going back to divvy more needed. Repeat this step with each proceeding colors, pouring into the middle of the last.

    Step 12

    There's no need to bake or really wait between layers. You can see here that the layers will spread from the center when poured. You may want to move the cup a little to help the batter spread evenly.

    Step 13

    After you get the hang of the layers, preheat your oven so it's ready when you are. Look at your cake mix for instructions. I'm going with 15 minutes on 350 degrees. They should come out fluffy.

    Step 14

    After letting them cool (where I used a cooling rack for best ventilation), you have the choice to frost and sprinkle them. You can use a knife or frosting bag and tip, like I have here.

    Step 15

    I used a basic white icing and just did swirls and ish. You do whatever you want. Then, I went kinda insane with the rainbow sprinkles. It's all up to your preference.

    Step 16

    Here I have a batch (and part of another) I made and as you can see, they look pretty cool iced, or not.

    Step 17

    I say they're pretty hecka dope. Thanks again for viewing my Snapguide and I hope you enjoy your own!
