  • Customizable: Choose your favorite colors or add extra decorations like sprinkles.

Ingredients

  • 6 cups crispy rice cereal
  • 10 oz (1 bag) mini marshmallows
  • 3 tbsp unsalted butter
  • Food coloring (red, orange, yellow, green, blue, purple)
  • Nonstick cooking spray or parchment paper

Optional Add-Ins:

  • Sprinkles or edible glitter for extra pizzazz
  • Vanilla extract for added flavor (1 tsp)

Step-by-Step Instructions

1. Prep Your Workspace

Line a 9×13-inch baking dish with parchment paper or grease it with nonstick cooking spray. Gather all your ingredients and food coloring to streamline the process.

2. Divide and Conquer

Divide the marshmallows and butter into six equal portions. Each portion will correspond to a different color layer. For reference, you’ll need about 1 2/3 cups of marshmallows and 1/2 tbsp of butter per layer.

3. Make the First Layer

In a large microwave-safe bowl, melt the first portion of butter (about 30 seconds). Add the first portion of marshmallows and microwave in 15-second intervals, stirring until melted and smooth. Add a few drops of red food coloring and mix until the color is even.

Quickly stir in 1 cup of rice cereal until fully coated. Press the mixture evenly into the prepared baking dish using a greased spatula or clean hands.

4. Repeat for Each Color

Repeat the process for orange, yellow, green, blue, and purple layers. Press each new layer gently on top of the previous one, ensuring even distribution but without pressing too hard (to maintain the light, airy texture).

5. Let It Set

Once all the layers are complete, let the treats cool at room temperature for about 1 hour. This helps them firm up for easy slicing.

6. Slice and Serve

Lift the entire block of treats out of the pan using the parchment paper. Slice into squares or rectangles with a sharp knife. Serve and watch them disappear!


Tips for Perfect Rainbow Rice Crispy Treats

  • Work Quickly: Marshmallow mixtures set fast, so have everything prepped and ready to go before you start.
  • Use Gel Food Coloring: Gel colors are more vibrant and won’t thin out your marshmallow mixture.
  • Grease Everything: Grease your spatula, hands, and any tools to prevent sticking.
  • Add Fun Toppings: Sprinkles or drizzle melted white chocolate over the top for extra flair.
