Peanut Butter Play Dough
Mix to desired taste. Powdered milk is a bit gritty right after mixing but it smoothes out after an hour or so. Ideal consistency is not sticky, mouldable. Shape into people, animals, battle scenes, etc. Then eat. I prefer to bite the heads off first, my son likes to start with legs.
Our son is often very finicky but if he's hungry he will scarf this down. I had presumed that it was very high in protein, but doing a little figuring I find it's only about 20% protein.
Using estimated proportions by mass= 5 Peanut Butter: 3 Powdered Milk: 2 Honey I get 140 calories/ounce with 20% protein, 50% fat, 30% carbs.
