I never looked into that, but it sounds interesting.
If you have a lot of chocolate chip mix or pumpkin bread or other bread mixes, it’s an easy thing to dump in to add different flavors. Or pancake mix with peanut butter powder, then eat the pancakes with jelly. Can be mixed with fruit and milk to make smoothies and add protein.
In an emergency, mix the peanut butter powder with water for PB sandwiches.
