Instructions

  • Start with your smallest purple layer as that will be in the inner core of your rainbow. Have either a piece of parchment paper, wax paper, or a silicon mat ready as a work station so you can shape your rainbow on a surface it won't stick to.
  • Put your purple layer butter amount into a saucepan, and warm until the butter has melted over low heat.
  • Add your marshmallows into the warm butter and stir with a spatula or spoon until the marshmallows have melted into the butter.
  • Add your food coloring to get the desired hue, stirring until color is even.
  • Add your Rice Krispies to the pan and stir to coat quickly and evenly.
  • Add butter or cooking oil to your hands, and roll out a purple log shape that's about 12" long on your work station. Press down gently to flatten out the bottom of the log just a bit. You can use a spoon or silicon spatula to shape if it's too hot to handle, and then switch to your hands once it's cooled down a bit.
  • Repeat the process of making your next color, blue, (washing out the pan or using a new one as needed) but instead of a log, shape a 12" long rectangle so you can drape the blue over the purple.
  • Keep repeating with green, yellow, orange, and red (or pink), making a 12" long rectangle each time to cover the previous color. Your rectangle will get a little wider as the colors continue because you'll have a wider area to cover. Use a spatula if you need help moving the last few wider colors up and onto the rainbow!
  • Once all your colors are added, allow your treat to cool completely and slice into rainbow slices!
  • Optionally, you can add some "clouds" at the bottom of your rainbows with some melted white chocolate by dipping or spooning some melted white chocolate onto the bottom edge of your rainbow slices. Just add three connecting dollops with a spoon on one side and add some white sprinkles if desired before the chocolate cools. Allow chocolate to set before serving or stacking to store your treats.

Notes

  • Going overboard on the food coloring can make your treat taste like...well, food coloring! So use as little as you need to get the hue you want.
  • Make sure you have your work station ready to go so the treat doesn't harden in the saucepan before you get your shaping station set up.
  • For your "clouds", try marshmallow slices, white cotton candy puffs, or white melting chocolate and white sprinkles!
  • Try adding a small dash of vanilla to your butter for a hint of warm vanilla notes.
