Homemade Flood Mud Microwave Hot Fudge Sauce

This recipe came to me from my sister-in-law Deborah, who has been one of the biggest supporters of this blog since Day 1. She actually shared it with me over 10 years ago and it’s the recipe I have used to make hot fudge for ice cream sundaes ever since.

Deborah has some excellent recipes and I’ve already shared her knotted orange sweet rolls on here and I keep meaning to share her cream puffs as well but just haven’t gotten around to it.

You basically can’t have an ice cream sundae bar without this hot fudge sauce. And nothing, NOTHING from a jar compares to homemade. I promise I’m not typically a snob about stuff like that (well, maybe kinda a little bit but we’re playing things cool, m’kay?) but man, oh man, this blows store-bought hot fudge out of the water.

Pour this decadent hot fudge over a scoop of ice cream, sprinkle it with some nuts, then top with whipped cream and a maraschino cherry for an old-fashioned ice cream sundae.

It’s even more amazing when you pair it with homemade marshmallow sauce, salted caramel sauce, or peanut butter ice cream topping.

What’s the difference between hot fudge and chocolate sauce?

We all agree that chocolate syrup and hot fudge are two totally different things, yes? Just wanted to make sure we are all on the same page. The biggest differences are texture and flavor. Hot fudge is thicker and richer than chocolate sauce. That’s because hot fudge is made with heavier ingredients like butter, cream, or evaporated milk while chocolate syrup is made with water or corn syrup.

If you are looking for a delicious chocolate sauce though, I’ve got one that I use for the chocolate ripple in my caramel oreo fudge ripple ice cream recipe.

How long does homemade hot fudge last?

This flood mud hot fudge sauce will last for 2 to 3 weeks in the refrigerator. This makes it a great hostess or neighbor gift idea.

Just know that when you refrigerate hot fudge, it will firm up. To loosen so the hot fudge is pourable again, just reheat in the microwave for 20 to 30 seconds, giving it a stir partway through.

If you don’t have unsweetened chocolate on hand, don’t sweat or run to the store. Just sub 3 tablespoons of cocoa powder and add 1 additional tablespoon of butter to the recipe and you are good to go!
