Old-Fashioned Homemade Vegan Fudge ❤️ Enjoy a bite of pure bliss with this traditional melt-in-your-mouth chocolate fudge - smooth, creamy, and deeply chocolatey. Just like Grandma's, but completely plant-based.
There's something irresistible about homemade chocolate fudge - rich, velvety, and unapologetically decadent. This vegan version delivers everything you expect from classic old-fashioned fudge, without dairy or shortcuts. Made with simple pantry ingredients and a little patience, it's a timeless treat that's perfect for holidays, gifting, or savoring slowly with a cozy cup of coffee or tea.
I've always loved chocolate, but fudge has a special place in my heart. From hot fudge sundaes to my favorite vegan devil's food cake with fudge frosting, that deep, silky chocolate flavor never gets old. For years, my mother-in-law's holiday fudge felt irreplaceable - until my daughter Madison helped crack the code.
The result is a truly old-school vegan fudge that rivals the original, much like our recipes for creamy homemade vegan chocolate pudding, and perfectly chewy chocolate chip cookies. Everything you want in a rich chocolatey treat - but without animal products.

Why this vegan fudge recipe works
Sometimes you really can't fudge a fudge recipe. To get this one just right, I enlisted the culinary creativity of my daughter to veganize her grandmother's beloved holiday fudge. The result is a truly old-school, candy-shop-style vegan fudge made with homemade aquafaba marshmallow fluff - no dairy, no added fat, and absolutely no compromise on texture or flavor.
This is not a quick, shortcut, 5-minute fudge recipe - and that's exactly why it works.
Traditional fudge relies on precise temperature control and sugar chemistry to achieve its signature creamy set. In this vegan version, aquafaba marshmallow fluff replaces dairy and egg whites, providing structure, stability, and that classic melt-in-your-mouth texture. When made correctly, this fudge slices cleanly, holds its shape, and tastes every bit as rich and indulgent as the original.
Why aquafaba marshmallow fluff is important
Aquafaba is the backbone of this recipe.
- It mimics whipped egg whites, creating structure and body
- It helps prevent graininess by stabilizing sugar crystals
- It contributes to a soft, creamy set instead of a brittle or gooey texture
Without aquafaba marshmallow fluff, this fudge would lack the stability needed to set properly while staying smooth and luscious.
You might be wondering - what is aquafaba?
Aquafaba (bean water) is the viscous water or liquid in which legume seeds such as chickpeas have been cooked. It is often used to replace egg whites in vegan cooking, and as a key ingredient in making plant-based desserts, such as meringue, icing, marshmallows, ice cream, nougats, and fudge. Learn more here.
How to make homemade vegan fudge
I'll be upfront - there are plenty of quick, "healthy," three-ingredient fudge recipes online. This is not one of them. If you're looking for true old-fashioned, candy-shop-style fudge with a rich, creamy finish, this method delivers. Best of all, it does so without harming animals. How sweet is that?
❤️ Ingredients
- Vegan chocolate chips or squares
- Oat milk (or plant based milk of your choice)
- Sugar (granulated)
- Vanilla
- Salt
- Cornstarch
- Vegan marshmallow fluff - aquafaba, vanilla, cream of tartar, sugar (recipe included)
❤️ Instructions
See the printable recipe card below for quantities & details.
This recipe is prepared in 3 steps
1. Combine chocolate, vanilla, and nuts
In a large mixing bowl - combine chocolate chips, vanilla and walnuts (optional). Set aside.
2. Make the vegan marshmallow fluff
Pour aquafaba, vanilla and cream of tartar into a deep mixing bowl. Using an electric mixer, whisk on medium speed until frothy. Increase speed to high. Gradually add sugar, one spoonful at a time until stiff.
Measure marshmallow fluff and combine with chocolate chips/vanilla/nuts. (You might have some leftover marshmallow fluff, which would be scrumptious on top of a mug of hot chocolate!)
3. Prepare the syrup
This step requires timing. You'll be moving quickly and non-stop so be sure to have everything pre-measured and ready in place. It's not absolutely essential, but having a candy thermometer will help to ensure that your fudge sets firmly.
Combine sugar, cornstarch and salt in a 4 quart or larger saucepan (deeper is better). Attach candy thermometer to pan if you have one.
Pour in oat milk and place over high heat, stirring continuously, without stopping.
The syrup will start to thicken slightly as it rises in temperature. Keep stirring and keep an eye on the temperature on your candy thermometer.
Continue stirring (about 7 minutes) until syrup reaches a rolling boil at 234° F or 122° C on a candy thermometer. Remove from heat right away (be careful not to let syrup boil over - it can happen very quickly).
Immediately pour syrup over chocolate chips & vanilla mixture.
Stir until fully melted and combined.
The soft fudge will likely have bubbles, which is perfectly fine. They will disappear while the fudge is setting.
Pour fudge into prepared/lined baking dish or pan. Cover with foil and refrigerate for at least 8 hours or overnight.
When firm, use a sharp pointed knife and cut into squares. This recipe yields approximately 36 - 42 fudge squares or more, depending on how large or small you slice them. I like to cut mine into about 1-½" squares.
❤️ Pro Tips
- Prep and measure all ingredients before heating the syrup - timing moves fast.
- Use a heavy-bottomed saucepan to prevent scorching.
- Avoid scraping the sides of the pan when pouring syrup, which can introduce unwanted sugar crystals.
Variations & add-ins
Have fun adding other ingredients if you like - such as:
- Chopped walnuts, pecans, hazelnuts, almonds or peanuts
- Mini vegan marshmallows (add with nuts for Rocky Road fudge!)
- Crushed peppermint candies or candy canes sprinkled on top
- Orange zest
- Flaked coconut
❤️ Equipment
- Electric hand mixer or stand mixer with a whisk attachment
- 2 large mixing bowls
- 4 qt or larger stovetop saucepan
- Hand whisk
- Silicone spatula
- Measuring cup
- Measuring spoons
- Food scale (optional but very helpful)
- Candy thermometer (recommended)
- 8" x 8" baking dish or pan
- Parchment paper or wax paper
❤️ Fudge FAQ's
How can I achieve the right consistency for vegan fudge?
The key to achieving the right consistency is to accurately measure your ingredients and follow the cooking instructions carefully. Use a candy thermometer to ensure your syrup reaches the right temperature.
Is vegan fudge as creamy and delicious as traditional fudge?
Absolutely! With the right ingredients and techniques, vegan fudge can be just as creamy and delicious as its non-vegan counterpart. We have compared our vegan version to traditional fudge recipes (containing dairy) and even non-vegans agree that ours tastes as good if not better than the others!
Why won't my fudge set?
If your fudge doesn't firm up, one of these is usually the culprit:
- The syrup didn't reach 234°F (soft-ball stage)
- The mixture wasn't stirred continuously
- Ingredients weren't measured accurately
- The syrup was over- or under-cooked
Candy making is precise by nature. Small temperature differences can have a big impact on the final texture.
Can I make vegan fudge without a candy thermometer?
Yes, you can make the fudge without a candy thermometer, but it requires a bit more attention. Follow the time guidelines in the recipe while cooking the syrup and use the "soft ball" test: using a spoon, drop a small amount of the hot mixture into cold water, and if it forms a soft ball, it's ready. Be very careful when testing the syrup, as it will be extremely hot.
Why Use a Candy Thermometer?
While it's possible to make fudge without one, a candy thermometer removes the guesswork.
- 234°F is the critical temperature for proper sugar crystallization
- Even a few degrees off can result in fudge that's too soft or too firm
- It ensures consistent results, especially for first-time candy makers
If you plan to make fudge more than once, this small tool is well worth it.
Storage, Shelf Life & Freezing
How long does vegan fudge last?
Stored in an airtight container in the refrigerator, this fudge keeps well for up to 5 days.
Does vegan fudge need refrigeration?
Yes. Refrigeration helps it maintain its structure and freshness.
Can vegan fudge be frozen?
Absolutely. Wrap tightly and freeze for up to 2 months. Thaw overnight in the refrigerator. The texture remains smooth and creamy when thawed properly.

jenifer Christensen says
This is such a weird recipe to me but it works. I used Coconut milk for my milk of choice and my non vegan friends keep asking me to make more. It's DELICIOUS.
Austin says
It tastes good, but it never set up. It's too soft to even cut into slices. I used soy milk instead of oat milk, but other than that I followed the recipe to a T.
Connie Edwards McGaughy says
Hi Austin, I don't think using soy milk would cause the fudge to stay soft. The one time it happened to me, it was because I didn't let the syrup heat to exactly 234℉, the temperature required for candy to form into a soft ball (like fudge). Lower than that and it will not set. Allowing the fudge to refrigerate for about 8 hours will also help the fudge to set.
Suzanne Gannon says
I made this and it tasted as I would expect something with so much chocolate and sugar in it to taste, which was nice and fudgy. I was wondering at the time of making it and now that it's finished what was the point of fluffing the aquafaba foam? The foam deflated as soon as the hot syrup was added and I can't detect what it actually added to the recipe. Did I do it wrong and the aquafaba was supposed to be an integral part that I inadvertently killed off?
Connie Edwards McGaughy says
Hi Suzanne, When we veganized my mother-in-law's original recipe (which included marshmallow fluff) we wanted to make sure we duplicated it as closely as possible, which resulted in a fabulous fudge that is as scrumptious as hers. The aquafaba needs to be beaten long enough turn into a light billowy fluff (like the image in the recipe post). It shouldn't be foamy or have noticeable bubbles. The fluff will become thinner once the hot syrup is stirred into it and the chocolate, adding a creamy, marshmallowy texture and flavor. I hope I helped answer your questions.
S.W. says
Any idea if it works with sugar substitutes? I have one vegan and one who doesn’t eat sugar!
Connie Edwards McGaughy says
Gosh, I haven't ever tried making this fudge without sugar since the recipe requires making a sugar-based candy syrup.
Julie says
How many ounces does the fluff recipe yield? Thank you!
Connie Edwards McGaughy says
Hi Julie, the recipe yields at least 3.5 oz. of marshmallow fluff, but I don't know exactly how much more than that may be left over.
Brittany B Lehman says
Due to peanut and tree nut allergies I can't use the bean water. Is there something else I can use instead? I can't have dairy either for the same reasons as the peanuts and tree nuts. Please let me know if there is a substitute ingredient that I can use instead. Thanks for your time.
Connie Edwards McGaughy says
Hi Brittany! I've tried to find other ways to create marshmallow fluff without using aquafaba and haven't succeeded . . . yet. I've seen vegan marshmallow recipes using pea protein, but I assume that might be an allergy concern as well? In the meantime, I plan to work on another vegan fudge recipe without marshmallow fluff. I'll keep you posted if I come up with a good one!
Nicole Connolly says
Can this be frozen to eat at later date? Thanks!!
Connie Edwards McGaughy says
Hi Nicole! I have refrigerated it up to a week (it gets firmer and a bit drier but still yummy). I haven’t tried freezing it though. Love to hear if you give it a try!
