Skittles Rainbow Cake with a Pouring Candy Illusion

Honestly who doesn’t love Skittles (if you hate Skittles I’m sorry and I feel sad for you!)?! Today, I’m teaming up with Jenn from Cupcakes and Cardio to bring you an OUTRAGEOUS Skittles recipe that takes this candy to new heights. This is my Skittles Rainbow Cake with a Pouring Candy Illusion! You’re going to have to go over to Jenn’s video for the cake recipe. Here, we’re going to just be decorating! YAY!

For this recipe, you’re going to need my Skittles sanding sugar. You can find that recipe here. You’ll also want some sugar cookies. You can find my recipe here. You’re going to want to save a packet of skittles for this pouring candy illusion! Make sure you save one of those Skittles wrappers for later, and tear it neatly.


  1. Preheat a moderate oven (175C/350F)
  2. Sprinkle sugar onto your bench and roll out your cookie dough into a long rectangle shape.
  3. Use your pizza cutter to cut out an arc to form the shape of a rainbow.dough-skittles
  4. Transfer to a baking tray lined with parchment paper.
  5. Bake in a moderate oven for 7-10 minutes, and once the edges begin to turn golden brown.
  6. Size up the rainbow to your cake. Trim the cookie if necessary.
  7. Paint melted white chocolate to the bottom 3 inches of the cookie on the front, and paint the entire back of the cookie with white chocolate, as well.
  8. Use your edible marker to draw 7 evenly spaced lines on the front of the cookie.
  9. Transfer your white chocolate into a snap seal bag. Pipe a line of white chocolate. Add sanding sugar directly onto the white chocolate. Do this for every color of the rainbow.rainbow-skittles
  10. Use a sharp knife to cut your Kit Kat bars into 2 pieces each.
  11. Place your Kit Kat pieces on 2 at a time around the entire cake. If the Kit Kats aren’t setting well, add frosting to the back of the Kit Kats.kitkat-skittles
  12. Use a knife to create a long slit in the top of the cake.
  13. Place your Rainbow Cookie through the slit.
  14. Place a corresponding Skittle color with the color on the rainbow. You can assemble them in a spiral like I did (this will take some time…it took me about 40 minutes), or you can pour them all into the cake with no particular design.candy-skittles
  15. Tie a red ribbon around the cake, and give it a nice big bow!
  16. With one of your old Skittles wrappers, pipe melted white chocolate along the inside of the top of the wrapper. Then, place it on top of the Skittles rainbow cookie.bag-skittles
