Rich Hot Fudge Sauce

I've made this scrumptious topping since the early 1980s. It always turns out smooth and yummy. The dark chocolate flavor, with a hint of rum extract, is not overly sweet but will still satisfy a chocoholic's cravings. —Carol Hanihan, Ann Arbor, Michigan

    Had no Karo so I used molasses, had no rum extract so I omitted it, and added espresso powder....maybe a Tablespoon......delicious, rich, thickened perfectly and great on my Perry’s French Vanilla Ice Cream. Yum Yum.....make some!

    I made half of this recipe exactly as written, and it was DELICIOUS! I will only use this recipe going forward. It's super chocolaty and the consistency is perfect!

    Love it. I didn't have any heavy cream so I just used equal amount of evaporated milk. It turned out wonderful. I also used 3 oz milk chocolate chips and didn't add the rum. Wisked the while time and was done in like 10 min total.

    OMG, this was excellent. Did not have any rum extract so substituted raspberry extract. My daughter is throwing a party later this summer and says I have to make a batch of this sauce for that.

    This hot fudge sauce is the deepest, richest, most chocolatey sauce ever. Great on banana splits or plain vanilla ice cream.

    This is absolutely, without any doubt, the best hot fudge recipe I have ever tasted in my life. DO NOT search for another recipe. I make practically everything from scratch, including fudge and I have tried many hot chocolate sauce recipes before and none come close to even matching this. The texture is amazing, just thick enough to slightly harden on ice cream, yet still stays very fudgy. Not runny or thin at all, stays nice on top of the ice cream, and the flavor is to die for! So rich, fudgy and totally out of this world. It is not grainy at all. Just perfect the way it is. The only thing I did different is omit the rum extract. Im sure it would be just as stunning with it in it. Perfectly WONDERFUL!
