DS age 10 does a strenuous activity 3 times a week and coach has said he needs to refuel his body within the hour with high protein bars, drinks etc.
OK all the bars, flapjacky, oakmealy things that are high protein eg. 21gs per bar in the shops he doesn't like.
So I thought I make myself, does anyone already do this and could share a recipe. He likes chocolate chip rather than nuts
