HI! I believe these are just standard rice crispy treats (marshmallow with melted butter….a drop of purple food coloring to get that lavender color….pour over rice crispies…..stir….looks like she then placed spoonfuls into little cupcake trays (be careful though because that mixture can get hot!) and before it cools, give it a dusting of edible glitter/sparkles. You could probably also just put it in a pan, add the colorful edible glitter/sparkles and then once it’s all cool, pull it apart to create the little balls. GOOD LUCK!
