Unwrap Peeps and place them in separate microwave-safe bowls by color. Microwave each for 30 seconds, stirring every 10 seconds until melted.

Add Rice Krispies to the melted Peeps and fold gently until fully coated.

Grease a 9x13-inch pan and press the first colored mixture into the bottom evenly, then repeat with each color.

Allow the pan to rest at room temperature for 30 minutes to set.

Use a greased knife to cut the treats into squares and place them on a serving platter.

Serve immediately or store properly to enjoy later.
