This is a really easy recipe that I found online. It uses Jello, marshmallows, and water..THATS IT!
These remind me of "fruit by the foot" or fruit snacks. I have used all different types of jello. I love orange jello with this recipe because the mix with the marshmallows reminds me of a Orange Creamsicle.
QUICK TIP: Trying to cut the pinwheel once it's rolled can be difficult with a knife. You can use dental floss to cut these and they turn out perfect every time.
Lightly spray an 8 or 9 inch square pan with cooking spray. If you do not have cooking spray you can also line the pan with plastic wrap so that it comes up the sides.
Mix the gelatin and water in a medium sized bowl until gelatin is dissolved.
Add the marshmallows until they are dissolved into the jello. If the marshmallows do not melt, place in the microwave for 10 second intervals until melted.
Gently pour the jello/marshmallow mixture into the pan.
Chill for 1 hour (The marshmallow and jello will separate forming two distinctive layers).
Remove the chilled jello from the refrigerator and remove from the pan or peel away from the plastic wrap.
TIPS FOR REMOVING THE JELLO: You may want to dip a butter knife in hot water and run in around the sides of the pan to loosen it. Also after loosening up the sides you can also roll the jello into a roll in the pan if you are having trouble getting it out.
With the jello side down (marshmallow side up) roll the square into a roll (pinwheel).
Use dental floss to cut the Jello into 1/2 inch slices. You should get about 10 to 12 pinwheels.
Serve immediately or chill in the refrigerator until needed.
