Hi Cheryl,

Soy nut butter is a great substitute to peanut butter! It is made from soy beans that have been soaked in water and then roasted. I haven't personally tried it, but it's completely free of peanuts, and is said to have the same consistency as peanut butter. You might try giving this recipe a peanut-free twist by simply replacing the cup of peanut butter with a cup of soy nut butter. I'm interested to hear how it turns out!

I hope there are several other answers to this one!  What a great question.  On the soy-nut butter, I know that I am not able to have it because I am allergic to both soy and peanuts.  Good luck!  I will keep checking back :)

It sounds like almond butter works, I stumbled upon this recipe: http://www.make-baby-stuff.com/almond-butter-playdough-recipe.html.  Perhaps sunflower seed butter might work, too?
Happy experimenting!

Hello,

Another potential substitute for peanut butter is tahini:

Tahini is made from sesame seeds.

Here's another recipe for edible playdough that doesn't include peanut butter:

Cake Play Dough

Ingredients:
1 package - white cake mix
1 stick - margarine
2-3 tablespoons water
Coloring - Pick your favorite food coloring

Use a mixer to combine most of the cake mix (leave a cup behind in case your mixture becomes to wet) with the margarine then slowly add the tablespoons of water until the consistency feels like Playdoh.

Once the consistency is right, take a chunk of the mixture and add food coloring.

Here's another edible playdough recipe that uses Kool-Aid that smells great:
