Ingredients
  

  • 3 tbsp butter Salted or unsalted
  • 10 oz mini marshmallows Standard bag size

Method
 

  1. Melt the butter in a large pot over low heat until fully liquid.
  2. Add the mini marshmallows and stir continuously until they are 90% melted. Do not allow the mixture to boil.

Protein Fruity Pebbles Rice Crispy Treats Tips & Expert Strategy

TEXTURE/MOUTHFEEL DISCLAIMER: These bars are engineered to be tender and gooey. If they feel extremely dense or hard, it means you either packed them too tightly into the pan or you overheated the marshmallows during the melting phase.
INGREDIENT SUBSTITUTION WARNING: Swapping the whey/casein blend for 100% whey isolate will fundamentally change the chemistry. Isolate dries out rapidly when mixed with sugar, leaving you with a rubbery, unpleasant texture. Use a blend for best results.
THE BETTER LATER RULE: While delicious immediately, the texture normalizes and becomes much better after resting at room temperature for an hour. This allows the milk and protein to fully hydrate within the marshmallow matrix.
PROFESSIONAL FINISHING TOUCH: To ensure you get perfectly square, bakery-style cuts without tearing the cereal, lightly spray your knife blade with nonstick cooking spray before slicing.
