Step-by-Step Instructions for Ruler Rice Krispies

  • Prepare the baking dish by lining it with parchment paper and spraying with non-stick cooking spray.

  • Layer the colored mixtures in the prepared dish, starting with red at the bottom, yellow in the middle, and plain on top.
  • Allow the layered Rice Krispies to cool completely at room temperature for about 30 minutes.
