Notes

Texture Control: These blondies are meant to be pulled while slightly underbaked. They firm up as they cool, locking in a fudgy interior.
Protein Choice: A whey/casein blend works best. Pure whey can dry the bars out.
Storage: Store in an airtight container in the fridge for up to 5 days or freeze individually wrapped bars for up to 2 months.
