I made these for my younger cousin Kaity, who is in love with all things rainbow. I made them for her 15th birthday on January 30th. I used the simple white cake recipe from my last post, and the same frosting recipe, but with powdered sugar this time.
Pictures first, explanation after:
So you're probably wondering how I made these normal-tasting cupcakes so psychadelic! Well first I made up the batter (you can use any white cake for this) and divided it into six bowls.
Then, I added food coloring to each bowl to make red, orange, yellow, green, blue, and purple batter.
Next I layered the colors into lined muffin tins. Purple, blue, green, yellow, orange, red, so that the rainbow pattern will be right side up. I smoothed each layer with a spoon to avoid waviness.
Then of course I baked them! To get the rainbow frosting, I did kind of the same thing. I made the frosting (of course you could use any white frosting) and divided it into six bowls. I colored each bowl with gel food coloring to avoid watery frosting, and layered them into my piping bag. Make sure to squeeze some of the frosting out of the piping bag back into a frosting bowl before piping onto the cupcakes as the bottom color (in my case pink) will be predominant until the rest of the frosting works down to the bottom of the bag. I didn't know this, so that's why the first three or so of my cupcakes were mostly pink. No matter, still awesome. To finish them off, I topped them with rainbow non-pareils! Kaity loved them, and so has everyone else that's seen them so far. They were super tasty, too!
