If you have the free recipe book from tryveg.com, this is in it.
I never follow the recipe directly.
Package of firm tofu
Package of vegan chocolate chips
Small jar of peanut butter
Soy milk to desired consistancy
Vegan pie crust, I used graham
Mix tofu, half of chocolate chips (melted), peanut butter, and soy milk in a blender or food processor until smooth. Spread in pie crust. I topped with the other half of whole chocolate chips ( I haven't eatten dessert since I became vegan, I went all out), but you can also add a topping of melted chocolate that will harden.
Chill for 2 hours. If adding melted chocolate on top: wait two hours, add melted chocolate, and chill another 2 hours.
