Grease a bread pan (8-9 inches) with nonstick spray and set aside.
Melt 1 tablespoon butter (not included in the Mason Jar gift) in a small pot over low heat. Once melted, add in all of the different peeps.
Stir constantly until the peeps are completely melted.
Stir in the crisp rice cereal until all the ingredients are well mixed.
Lightly press (don't push too hard or it will make these treats harder and less chewy!), the mixture into the bread pan.
Top with desired amount of sprinkles.
Cut into 6 small squares and enjoy within the same day.
(These treats are best enjoyed the first day and don't store very well.)
