My Mother In-Law taught me how to make this for my daughter who is on a GF/DF diet. She came up with this recipe herself! It was very easy and the pie held up very well. I used the "Silk" brand Chocolate Soy milk and I even had a piece of it and it was so delicious! We doubled the recipe to make two pies, as my Brother In-Law is lactose intolerent as well. We also used the nabisco brand chocolate and shortbread ready to use pie crusts, so it was very easy! *Note* When I wrote out the ingredients, I mistakenly put the instant pudding mix, but this recipe uses the Cook and Serve pudding mix. Also as another note, the chocolate pie filling is Gluten Free, but the pie shell was not, so if you want to keep it gluten free, you'll want to probably make your own from other recipes that you may know of, as I don't know of one right now. *Update* I had this recipe named gluten free and sugar free in the title of the recipe but seeing that chocolate soymilk has sugar and that the pie crust does include gluten flour, I have changed the name to just Dairy Free Chocolate pie. Hope this doesn't confuse anyone! Enjoy!!
