Spray an 8x8 pan with nonstick cooking spray. Set aside.

Place the jello powder in a medium mixing bowl and add the boiling water.

Whisk lightly until dissolved or close to it.

Add the marshmallows to the bowl and microwave on high for 1 minute and 30 seconds.

Remove and whisk again until there are no marshmallow lumps.

Pour into the prepared pan and place in the fridge for 2 hours or until set.

Remove by gently pulling up one corner and slowly peeling it out of the pan.

Roll into a tight tube like you would cinnamon rolls. Place back in the pan and back in the fridge for about 10 minutes.

Remove and slice into ½ inch pieces using a sharp knife. Do not saw back and forth, one cut, straight down.

Serve and enjoy!
