I really like this receipe, but did make some changes I got from previous reviewer. I used the Oreo Pie crust. The filling is great (add the extra egg white) but I need more so the next time I will increase the ingredients, as I did for the topping, I doubled the receipe, adding the vanilla and added maple syrup, (don't like instant coffee) so the topping came out great, very tasty. To top if off I used Heath chips. Thanks for the receipe.
