You will need:
1- 3 oz. box of Jello (flavor is your choice)
1/2 cup water
1 cup mini marshmallows
In a glass 8x8 dish, spray lightly with cooking spray and then use a paper towel to spread it around and thin it out. Set aside.
In a bowl add in jello powder and 1/2 water. Microwave for 30 seconds and then whisk. Make sure all jello powder is dissolved. Micro another 20 seconds if you need to, but you should be OK with 30. Now add in your marshmallows and stir them around until they are coated. Microwave another 30 seconds. Stir marshmallows (or whisk) until they are all combined. If they aren't all melted microwave in 20 second increments to get them all melted and combined with the jello. Pour mixture into your greased dish and refrigerate at least 1 hour. You will see the marshmallows in an act of extreme magic, separate from the jello to form 2 layers. When your mixture is set, run a knife around the perimeter and picking up one small corner and working your way across, start rolling the jello. You an easily lift it out and place on a serving tray. I cut these with a thread, get it underneath the roll and cross your threads and pull to cut. You could also use a very sharp knife.
These are fun and could be made to fit color themes or holidays!
