Peanut Butter Clay

4 Tbsp peanut butter

1 Tbsp honey

1Tbsp wheat germ

2 1/2 Tbsp powdered milk

Eat. Sculp. Mix!

Just want to say that this is a big hit with my kids, they ask for it all the time.  Oliver has a milk allergy, and I never have milk powder anyhow, so I use flour and it turned out just fine.  It's really easy to play with the ingredients to get the consistency you want - sometimes I add oatmeal for a bit different texture.
