Woo! That’s fantastic! Protein powder bakes so well!
Here is a link to some of Jamie Eason’s protein powder recipe’s.
But you’ll be amazed at what you can find with a simple Google search. You can probably add it to breads (imagine using it in cornbread… mmm nice and sweet! Probably just as effective as adding the sugar and vanilla extract like I normally do) Just be creative and think about the flavors you are cooking with.
