For best results let the hot fudge actually cool down a little from off the stove. Traditionally served warm in old fashioned ice cream shops so it would not melt the ice cream too quickly. This sauce can be used on Bundt cakes, cupcakes and with brownies. It has a more limited use than most other recipes I've published, but I thought it would be good to get a baseline for hot fudge sauce. While this sauce is very delicious, I will publish more modern versions in the future.
