Common Questions
Can I use a different protein powder?
Whey protein works best for the texture of these blondies. Plant-based powders may make them a bit drier. If you use plant protein, add an extra tablespoon of milk.
How do I know when they are done?
The edges should be slightly golden and firm. A toothpick should come out mostly clean from the center. They will firm up more as they cool down.
Will my kids actually eat these?
Yes, they taste just like a classic peanut butter treat. The chocolate chips make them feel like a real dessert. They won’t even know they are eating protein.
