Editor’s note : Something you likely don’t know about me is that Rice Krispies Treats are, bar none, my all time favorite snack. As a kid I enjoyed making them, and I could eat through an entire pan in no time. Then as a pregnant lady, I craved them even more than usual. And, surprisingly, with my pregnancy sickness, they were the one thing I was able to eat pain free! And eat them I did! Ha. It was practically a daily indulgence for me. 
 
Having said all that, I was thrilled when I discovered Jessica Siskin (@mister_krisp) on Instagram. It’s been so fun to watch her grow while creating these colorful creative concoctions. And now I’m so thrilled for her to be coming out with a book.
 
In honor of “Treat Yourself : How to Make 93 Ridiculously Fun No-Bake Crispy Rice Treats” coming out next Tuesday, we have Jessica here today with step by step instructions on how to make her rainbow cake, which is, of course, the one we immediately gravitated towards, considering we’ve already made our own versions of rainbow cakes (here and here)! No surprise there, right? As well, Jessica is giving away two copies of her book, so keep on reading. 
 
 

Rainbow Cake 

Everyone’s dream birthday cake might not be a cake at all! This impressive-looking layer “cake” can be customized for any celebration by experimenting with different colors and decorations. I’m obsessed with the sprinkle mix on top, which I made by combining every variety of sprinkle I had in my pantry. Sometimes (always) more is more!

Makes 1 cake, 8 inches in diameter and 8 inches tall

Instructions

  1. Coat the inside of the cake ring with cooking spray and place it on the parchment-covered work surface.
  2. Mix the yellow F batch recipe: In a large stockpot, melt the butter over low heat until it’s 80 percent melted (see photo), about 1 minute 20 seconds. Note: If the butter begins to sizzle, lower the heat. It should melt very slowly.
  3. Add the mini marshmallows and stir gently, coating them with melted butter, about 30 seconds.
  4. When the marshmallows are about 80 percent melted (when you can still see the individual marshmallow shapes but they are beginning to run together), add the food coloring. Stir for another 15 seconds and then turn off the heat.
  5. Stir gently until the color is well distributed but the marshmallows are still only about 80 percent melted, about 35 seconds (you should still be able to identify individual pieces within the melted ones). Note: If the marshmallows melt too much, the mixture will be too hot to handle—wait 1–2 minutes and then mold quickly!
  6. Add the cereal and mix well, until the marshmallows and cereal are fully combined, about 40 seconds. Do not overmix! Once done, pour the mixture into the cake ring. Generously coat your hands with cooking spray. Press to flatten until the mixture begins to firm up. Place the treat with the cake ring in the freezer while you repeat steps 2–6 to make the green F batch recipe. (Note: Each layer should stay in the freezer for at least 10 minutes.)
  7. Remove the cake ring from the yellow treat (leave the treat itself in the freezer), and recoat it with cooking spray. Pour the green mixture into the cake ring and press to flatten until the mixture begins to firm up. Place the green treat with the cake ring in the freezer while you repeat steps 2–6 to make the turquoise F batch recipe.
  8. Remove the cake ring from the green treat (leave the treat itself in the freezer), and recoat it with cooking spray. Pour the turquoise mixture into the cake ring and press to flatten until the mixture begins to firm up. Place the turquoise treat with the cake ring in the freezer while you repeat steps 2–6 to make the purple F batch recipe.
  9. Repeat with the remaining purple, pink, and orange F batch recipes until you have six frozen layers.
  10. Determine the order in which you’d like the six treats to be stacked. Using the spatula, spread buttercream frosting over the top of the bottom layer, making sure to reach the edges.
  11. Carefully place a treat on top, for the second layer.
  12. Spread buttercream frosting over the top of the second layer, and place another treat on top.
  13. Continue in this manner until all of the layers have been frosted and placed.
  14. Spread one last layer of frosting over the top layer, making sure to reach the edges.
  15. In a bowl, use your hands to mix together the different varieties of sprinkles, then sprinkle them over the frosting.
