I was looking for a version of this pie that I had made some years ago. I couldn't find the exact one but I did find this one that can easily have coffee added to it and some walnuts popped on top. https://southernfoodandfun.com/old-fashioned-fudge-pie/
If I times the amounts by 2 - 3, can I do that with all the ingredients or would I have to make some special adjustments? I hope to make a large one (in a rectangular tin) rather than 2 or three smaller ones. Also, is it a traditional recipe from anywhere in particular in the world?
