Start with taking the ice cream out of the freezer to soften a little bit. This will help to easily spread it on the rice Krispy sheet.
Add the butter and marshmallows to a sauce pan and turn the stove on medium heat.
While the marshmallow is melting add the dried cereal in a large bowl.
Once the marshmallow is completely melted add it to the dried cereal. Mix all ingredients until combined. Now you may have to use a little muscle to make sure all the cereal is coated with the yummy marshmallow sauce.
Spread the mixture on a silicone mat or baking pan lined with parchment or wax paper and press lightly. Form a rectangle. I found the silicone mat worked so much better. The mixture did not stick at all.
Spread the ice cream all over the top of the mixture. Take the short end of the mixture and mat and start rolling like you would a cinnamon roll.
Place the rolled mixture in the freezer for about 30 minutes. Longer if you can.
Cut the mixture into about 1 inch pieces and enjoy!
