I've never made them with cannabutter, but I like to make rice crispy treats. I make them all different ways... if you like Peanut Butter, put a little in with the melted marshmellows and let it melt too, then mix in the crispies, and drizzle with melted choclate chips after it cools a little. I also make them frequently with cocoa crispies. Do you see a theme here. I really like chocolate.
