Moho I think you should make rice crispy treats. all you need is something to heat the butter to melt it like warm or boiling water. Put a bowl of hot water with a cup in it with your cannabutter. Once its melted all you need is a warm enough device to melt/soften the marshmallows. Adding the melted butter, just after you start to soften the marshmallows, will help the marshmallows melt faster/better.
