Keto/Low-Carb Fudge

Ever you walk past a fudge stand and it becomes all you can think about? It consumes your every thought to the point where you don’t even remember your own name? Well, if you’re on a low-carb or keto diet, this keto/low-carb fudge is the answer. Not only is it simple to make, it’s incredibly delicious – and you’ll remember your name.

For some reason, I think we all believe that fudge is really difficult to make when in actuality, it isn’t. The toughest part is getting the correct ingredients, getting good ingredients, and waiting for the fudge to cool after cooking. The latter, being the most difficult piece of the puzzle.

What Cocoa powder to use?

You want to use 100% cocoa powder. Cocoa powder is basically chocolate that has had the fat removed, leaving behind a chalky dry powder – that’s what we want. As long as your cocoa powder is pure, you should be good. There are tons of varieties depending on where they’re sourced from, how they’re processed, if it is organic or not, FairTrade etc. Overall, the most important aspect is that the label says 100% cocoa powder.

Is this fudge Keto friendly?

Yes! The carbs that are in this recipe mostly come from residual carbs from the heavy cream, minimal residual carbs from the cocoa, and the rest are sugar alcohols from the chocolate chips. Just be careful not to overindulge – I know this fudge is really good. It’s best to eat it with friends so that there’s none left over that you can scour as a snack later on.

Can I add Peanut Butter?

Sure! However, that’s a different recipe – and one that I’m currently working on. Adding peanut butter to this recipe, it would have to be a substitution, otherwise it would be too wet of a fudge and resemble more of a pudding.

What if I really want pudding instead of fudge?

If you have some overripe avocados, you can make chocolate pudding with them! Check out the recipe for my Low-Carb Chocolate Pudding

Keto/Low-Carb Fudge

Yield: 9
Prep Time: 5 minutes
Cook Time: 15 minutes
Additional Time: 2 hours
Total Time: 2 hours 20 minutes

This fudge is creamy, soft, and just the right amount of sweet and chocolate richness!


  • 1 cup heavy cream
  • 2 tbsp unsalted butter
  • 1 tbsp vanilla extract
  • ⅓ cup erythitrol
  • 1 cup sugar free chocolate chips or bars
  • splash of whiskey (optional)
  • walnuts or pecans (optional)
  • flaky sea salt (optional, but highly recommended)


  1. Set a pan to medium heat. Add your heavy cream, butter, vanilla, and sugar. Once the sugar has dissolved, add a splash of whiskey if you choose to.
  2. Stir for 15 minutes or until the mixture turns a golden brown and the sauce thickens (it will thicken more as it cools).
  3. Remove from heat and let cool for about 10 minutes.
  4. In the meantime, line a small dish with parchment paper on all sides, with enough overhang that you will be able to use it to lift the fudge out from the container. You can get fancy with the geometry and the folding, but it's not necessary.
  5. Pour the mixture in and spread out evenly.
  6. Optional: top with your nuts of choice and the flaky sea salt.
  7. Place into the refrigerator for at least 2 hours.
  8. Remove from the fridge. Using the parchment paper, lift the fudge from the container.
  9. Cut the fudge into smaller serving size pieces and enjoy!


TIP: if you let the fudge warm up a bit, they will be creamier and smoother!
