Prepare an 8-9 inch loaf pan by lining with foil and spraying lightly with cooking spray.
Divide the Peeps by 10s of the same color.
In a deep, microwavable dish, microwave 10 of the same colored peeps with 1 tablespoon of Grassland butter on high for 45- 60seconds. The Peeps should be puffy when removing the bowl from the microwave.
Mix the melted Peeps until smooth, then add 1 ½ cups of Crispy Rice. Mix together. (it will get sticky)
Add the mixture to the loaf pan, and pat down.Follow steps with remaining Peeps, and press each individual color into the loaf pan one on top of each other.
Transfer the loaf pan to the fridge to cool completely before slicing.
