Prepare the Soft & Gooey Rice Cereal Treats per instructions in addition to adding the green gel color and sanding sugar/sprinkles when the rice cereal is added to the marshmallows. Mix thoroughly until entire mixture is green. You may reserve the sprinkles until the treats are cut and add them to just the surface if you prefer.
Once the treats have cooled in the pan, use the cookie cutter to cut the shapes out.
You can seal an entire plate of treats or seal them individually and hand them out as gifts. Either way, make sure to seal them tightly to keep them fresh!
