Basically, instead of using marshmallow, I substituted with mochi which is surprisingly gelatin-free. It came out really great and I added some vanilla extract and sugar to sweeten it up.
It was kind of an accidental idea. I work at a frozen yogurt shop and we got a bad batch of mochi (it was melted) and the first thing I thought of was rice krispie treats and voila!
So, has anyone else tried this? If not, I hope someone else will experience the greatness I have found.
Basic recipe is as follows:
3/4 cups vegan margarine
1 case of mochi
vanilla extract (optional, to taste)
sugar (optional, to taste)
4 cups of rice krispies
heat and melt margarine with mochi, vanilla extract, and sugar. Then simply mix in with the krispies and use a "buttered" spatula to spread on to a pan. I let mine sit in the fridge for a bit so it wouldnt be too chewy.
