What makes this the best?
This ice cream sauce is not the best because it has the fewest ingredients. No, that prize goes to good old ganache which makes a fine ice cream topping, clocking in at 2 or maybe 3 ingredients.
If you’re looking for good, old-fashioned hot fudge sauce, though, you need look no further.
Here are the things that make this fudge sauce the best:
- It gets thick and a bit chewy when cold.
- You have to heat up in order to pour it.
- It has a deep, rich flavor that is exactly what is needed to set off a perfect vanilla ice cream. Or coffee ice cream.
- There is enough salt in it to round out the flavors, counteract any bitterness that might be present if you use a really dark chocolate, and to make the sauce sparkle on your tongue.
- You can vary the flavor based on your preferences.
It is truly an old-fashioned fudge sauce with you’re going to want to make again and again.

Ingredients and Substitutions
NOTE: If you don’t need all the step-by-step instructions, feel free to jump straight to the recipe.
The ingredient list is actually relatively long, but the process is pretty straightforward. Here’s what you’ll need:
- butter: the fat helps to carry the flavor and provide body. If you don’t have unsalted butter, use salted, but you may have to dial back amount of additional salt you use
- sugar: provides the sweetness and helps to give the sauce the traditional “chewy” texture of old time soda fountain hot fudge sauce. You can substitute light brown sugar, 1:1, if you would rather
- corn syrup: light or dark. Helps to prevent crystallization and provides more of the chewy texture we’re going for
- heavy cream: provides body and volume as well as additional milk fat. The dairy solids in the cream will brown as you cook the base, adding to flavor complexity
- salt: enhances the flavor and counteracts any bitterness from the cocoa powder
- milk: provides more volume without adding much additional fat. Also adds more dairy solids that will brown as they cook
- cocoa powder: provides the chocolate flavor. Use the best quality you can get, although honestly any will do. I make mine with Hershey’s (or Ghirardelli when I can find it) and it’s fantastic, either way. DO NOT use cacao powder which is not roasted or heated during processing. It is too delicate to provide the punch of chocolate flavor we are looking for
- water (or coffee): gives you something to make the cocoa powder paste with. If you use coffee, it will help to deepen the chocolate flavor just a touch
- light rum: adds enough alcohol to bring out alcohol-soluble flavors without being a prominent flavor itself. You can certainly sub in your favorite liquor or liqueur here, depending on what flavor you’re going for. You can also leave the alcohol out entirely if alcohol is an issue for you. Coffee makes an excellent substitution here, and you will not be able to taste it in the final sauce
- vanilla: chocolate’s complement. Must have! You don’t have to use the top quality stuff, but adding vanilla helps to round out the flavors
- semi-sweet or bittersweet chocolate: adds additional chocolate flavor plus some cocoa butter for body
How to Make Hot Fudge
There are two basic components to this sauce:
- dairy and sugar
- chocolate and flavorings
The goal is to boil the dairy to concentrate the flavors and reduce the liquid and then pour that over the chocolate and whisk to combine.
Here’s a closer look at that procedure.
You have 2 “mixtures” to deal with.
For the dairy portion, mix heavy cream, milk, sugar, corn syrup, and salt together in a medium saucepan.
Bring it to a boil and cook, stirring occasionally, until the mixture caramelizes but isn’t too, too thick.
The magic temperature, if you want to use your instant read thermometer is 224-225F. This is technically the thread stage, and if this was the only component of the sauce, it would stay runny in the fridge.
But since the other part of the sauce contains a lot of chocolate, it sets up very thick, almost like peanut butter.
And that’s what gives you that chew when the warmed up sauce hits cold ice cream. Magic!
All the rest of the ingredients go into a large bowl or pitcher that holds at least 1 quart/1 liter.
- Chocolate, cocoa powder, rum (if using), vanilla, and water go into the bowl.
- Once the dairy is beautifully caramelized, pour it over the chocolate.
- Whisk until smooth.
- For the smoothest texture, strain through a fine-mesh strainer. This is an optional step, but since it doesn’t take much time, I usually strain mine.
Fudge Sauce Variations
This sauce can be flavored in many ways. Here are some ideas to try:
- Add a bit of orange zest and/or cinnamon to the boil
- Switch out the rum for orange liqueur.
- Use your favorite alcohol–a liquor or liqueur.
- Add some peppermint extract.
- Whisk in powdered freeze-dried raspberries or other freeze-dried fruits.
- Add some heat in the form of chipotle pepper or smoked hot paprika
Play with this sauce and make it your own.

When you want to relive your visits to the soda fountain where the fudge sauce was thick and rich and tasted of fudge and not “brown,” then please make it according to the original recipe which calls for light rum and vanilla.
Jenni Says: If you are not averse to having alcohol but don’t happen to have any on hand, use vanilla extract in place of the rum. I’ve done that before, and it’s delicious! If you want to make your sauce alcohol-free, substitute coffee for the rum.
NOTE: Since this hot fudge is dairy-based, it is not recommended to can this.
If you want a non-dairy chocolate syrup that you CAN can, check out my chocolate syrup recipe.
Hot Fudge Sauce Q & A
Since you add the boiled mixture to the alcohol mixture off the heat, none of the alcohol boils away. And even if you do boil it, while most will boil off, not all will. If for any reason you cannot have alcohol, you can substitute 2 Tablespoons of very strong coffee.
If you follow my advice to cook to no more that 225F, you shouldn’t have any issues. The fudge sauce will get chewy but not hard on ice cream. If you overcook and it does get too hard on ice cream, reheat the batch with a bit more cream or milk to loosen it up a bit.
When you pour your fudge sauce on your ice cream and it seems too thin, all running off and into the bottom of your bowl, scrape the rest of the sauce back into a pan, bring it to a boil, and let it boil for a couple of minutes th thicken it up. If using a thermometer, bring the sauce to about 225F.
Do I have to caramelize the dairy mixture?
While it’s optional, Tangela shares this comment:
Caramelizing the sugar/dairy does a couple of things:
- It evaporates out some of the water, concentrating the flavor and allowing for a thicker sauce and that old-fashioned chewy texture that is so incredibly addictive.
- The caramelized sugar and milk solids lend a deep, complex base flavor that you would not get if you don’t take this step.
If you want to use your instant-read thermometer to check doneness rather than just going by color, shoot for 224F/107C.
Here’s another comment in support of taking the time to caramelize the dairy in your hot fudge sauce so it really will be the best:
Pro Tip
The hotter you cook your sauce, the thicker it will be upon cooling. I generally go with the color of the dairy rather than whipping out my instant-read. Take the dairy to a light beige color, and it will still be fairly liquid (although thick) upon cooling. Take it to medium beige, and your fudge sauce will be more solid once chilled.
For me, the magic temperature for cooking the dairy portion is 225F/107C.
Unless you plan on eating it straight from the jar with a spoon, always reheat the sauce before serving.
Other Delicious Dessert Sauces
As much as I will almost always reach for hot fudge sauce to top ice cream, there are times when you may want a different flavor.
Here are some more dessert sauce recipes on the site:
- Try rich butterscotch sauce
- Especially tasty in the fall, pumpkin caramel sauce is great as a dessert topping or stirred into your coffee
- In the springtime, when strawberries are ripe and perfect, try some strawberry syrup over vanilla or strawberry ice cream
- For a decadent take on a chocolate sauce, try my chocolate peanut butter sauce made with peanut butter porter

A Note About Measurements
NOTE: Most of my recipes are written by weight and not volume, even the liquids. Even though I try to provide you with volume measurements as well, I encourage you to buy a kitchen scale for ease of measuring, accuracy, and consistency.
Don't let its small price and small size fool you. The Escali Primo is an accurate and easy-to-use food scale that I have used for years. It's easy to store, easy to use, has a tare function, and easily switches between grams and ounces/pounds for accurate measurements.

Ingredients
- 4 oz unsalted butter (1 stick or 112 grams)
- 8 oz granulated sugar (1 slightly generous cup or 224 grams)
- 11.75 oz by WEIGHT light or dark corn syrup, (1 cup or 329 grams)
- 16 oz heavy cream (1 pint, 2 cups or 448 grams)
- ¾ teaspoon kosher salt
- 5.3 oz whole milk (about 2/3 cup or 149 grams)
- .67 oz cocoa powder (1/4 cup or 19 grams)
- 1.3 oz water (2 Tablespoons plus 1 teaspoon water or 36 grams)
- 1 oz light rum (2 Tablespoons or 28 grams)
- 1 teaspoon vanilla extract or vanilla paste
- 8 oz excellent quality semi-sweet chocolate, chopped or good quality chocolate chips (I used Ghirardelli 60%, 1 1/2 cups or 224 grams)
Instructions
- Place the butter, sugar, corn syrup, heavy cream, salt and milk in a large, heavy-bottomed saucepan. Heat over medium heat until it comes to a boil.
- Meanwhile, whisk together the cocoa powder, water, rum and vanilla into a thin paste.
- Place the cocoa paste in a large bowl.
- Chop the chocolate into small pieces (or use excellent quality chocolate chips or paillettes) and add to the bowl.
- When the dairy comes to a boil, regulate the heat so it maintains a slow boil but doesn't boil up in the pan.
- Stir the dairy frequently and boil until it reaches a light caramel color, about 20-30 minutes (less time if you half the recipe). You don't necessarily want the mixture to be super thick, but you do want it a few shades darker than when you started. If you have an instant-read thermometer, the ideal temperature to shoot for is 224F.
- Once the dairy is a lovely shade of deep beige, pour it into the bowl with the chopped chocolate and cocoa paste. Allow it to sit for a minute or two and then whisk until smooth.
- Optional: Strain it just to make sure it is completely smooth.
- Store in jars in the fridge.
- If you used fresh dairy, the hot fudge sauce will keep for a good 2-3 weeks in the refrigerator. If your dairy was close to the expiration date, use the sauce up within 5-7 days.

Storing
Keep sauce tightly covered in the refrigerator for up to two weeks. It will probably be good for longer than that, but use your best judgment. You can freeze the sauce for longer storage. This sauce is not suitable for canning unless you are well-versed in canning dairy products.Nutrition

This recipe is awesome!! truly never had anything fudge that tasted this smooth! A+, well done! thank you for the recipe.
The only change I made was replacing the corn syrup with organic brown rice syrup. (corn allergy)
This recipe is THE replacement to my previous fudge sauce recipe.
I’m thrilled you love it! And very good sub with the brown rice syrup too. ❤️
If I want to make this without the rum, do I need to adjust any other ingredients?
It calls for 2 Tablespoons of rum, so you won’t have to make many adjustments. If looking for a non-alcoholic version, I generally increase the vanilla by a little and replace the rum with some strong coffee. Enjoy!
Hi!
I have made this before and it is DELICIOUS!
My question is, if I use it in an ice cream cake as a layer, will it freeze hard or stay somewhat pliable?
Hi, Jeanette! So glad you love this sauce–me too! It will definitely get firm but there’s too much sugar in it to get really hard. You should be able to slice it, especially with a serrated knife. Just keep the layer fairly thin since it could easily overpower other layers. Enjoy!
thank you for responding so quickly!
My pleasure! I try never to leave anyone hanging. Let me know how the cake turns out, Jeanette!
Can you use Frys Cocoa in this recipe? Also, you stated you use Hersheys. But what kind of Hershey’s? Is it the Hersheys natural cocoa unsweetened powder or the 100% cacao unsweetened brand? Don’t want to make this and ruin the recipe due to the type of cocoa.
Hey, Corrie! Honestly, any cocoa powder you like will work. You’re right to check though. I would choose cocoa powder over cacao since most health benefits of using a raw cacao are going to be boiled away. I’ve made this with everything from Hershey’s and Nestle 100% cocoa powder to fancy brands like Valrhona when I was at the restaurant. I’ve never had a bad batch. I really hope you enjoy it. Oh, and just to make sure you saw: if you choose to use honey or another liquid sweetener over corn syrup, you may need to increase the cocoa powder and the chopped chocolate by a little bit so the overall flavor is balanced. Enjoy!
So yummy, made great holiday gifts! How much is a serving per your nutritional analysis?
Hey Deb! So glad you like the sauce, and I hope your giftees love it to. I’m pretty sure I based the nutritionals on a 2 Tablespoon serving.
I just made this twice, and am THRILLED to say the least! The first time I followed the recipe using Ghirardelli 48% cacao chocolate chips. It tasted great, even cold, like tootsie rolls. The second time I used 60% cacao Ghirardelli chips and coffee instead of water. WOW! It’s rich and velvety and chewy and decadent! I am so impressed with the results! Both times I weighed everything. (I actually prefer using weight rather than volume, as it’s more exact) and I patiently brought it to 224/225 both times, using an instant reax thermometer. I used light rum and vanilla as listed in the ingredients both times. This is TO DIE FOR fudge sauce! THANK YOU!
Oh, MaryLou, I am so happy!! I love your description–you so accurately capture it: rich and velvety and chewy and decadent! I’m also glad you are comfortable using a kitchen scale. It really is best for getting the most accurate and consistent results. Thank you for taking the time to send some feedback–enjoy every bite!
If you love chocolate you will love this recipe . Definitely lives up it’s title.. This is the best recipe for the best hot fudge sauce ever. It’s the only one I make anymore.
I am so glad you’ve adopted this as your favorite, Pam! And thank you also for the review–I appreciate it!
I usually make a 2-minute blender hot fudge but I wanted to try to get that “chew” that you find in icecream shops. This taste good but I don’t feel a “chew” to it. I have one of those glass top stoves and it is very difficult to just temperature. It would be helpful for me if I knew the temperature to cook the mixture to. I used dark corn syrup in a dark pan so I couldn’t really go by color, just time
The chew doesn’t happen until you chill it, either in the fridge or by pouring it on ice cream. If it doesn’t have it, heat it back up and simmer some more. I’d say take it to 230-232F. Enjoy!
This would be a great treat for the holidays.
Absolutely! It keeps for a good long while in the fridge, too!
