The recipe for Keto Chocolate Fudge

This recipe may be low in carbs and sugar-free, but you would never know it. This fudge turns out  rich and creamy–just like fudge should be! 


I stirred in some walnuts at the end to add a but of crunch and to balance out the sweetness of the chocolate with some nutty goodness. The result is an old-fashioned homemade fudge that’s just as tasty as the sugar-laden variety.


Best of all, this recipe is so easy to make! Some low-carb fudge recipes require you to make condensed milk before you ever get started on the recipe.  Of course, this takes time. On the other hand, my recipe only takes about 10 minutes of hands-on time.


There are a few things that do take some time with this recipe, but they are hands-off. For example, you do need to cool the chocolate and cream mixture for a while before adding it to the cream cheese mixture, but you can do other things while it cools. Of course, the hardest part of making this fudge is waiting for it to set. 


This fudge makes a great treat for the holiday season. Eat it yourself, or give it to your favorite person who loves chocolate, but eats a low-carb diet. It’s also perfect for a keto Valentine’s day treat.

The inspiration

As the holidays approach, I started thinking about recipes I like to make for the holiday season. I used to always make fudge. One of my favorite fudge recipes was chocolate fudge with walnuts. It was lovely for nibbling and made a great give. 


Now that I eat keto, I wanted to recreate this fudge in a version that I could eat. I used Harper’s recipe for Low-Carb Homemade Nutella Fudge as a guide and reworked it a bit to make a chocolate and walnut version.

How to store fudge

This fudge should be stored in an airtight container in the refrigerator. If you stack pieces on top of each other, be sure to put a piece of parchment paper in between so they don’t stick together.


Before covering fudge, make sure it is completely cooled. This will prevent condensation from developing on the lid of the container and dripping down on the fudge.

Can fudge be frozen?

If you will not be eating this fudge right away, you can freeze it. Simply put it in a freezer-safe container. Be sure to cut the fudge first.


Lining the container with parchment paper and putting parchment between layers will help you remove small amounts of fudge at a time. 


You will want to defrost each piece of fudge at room temperature for 10-15 minutes before enjoying to restore it to its creamy glory.

Tips and tricks

While I love the smoothness and boost of protein that the collagen adds to this recipe, it is not necessary for the fudge to turn out. 


The nuts in this recipe are optional. You can leave them out, or you may substitute the walnuts with your favorite nut. Pecans makes a wonderful substitute.


I used powdered Pyure baking blend in this recipe. You could substitute granulated Pyure, but be careful about substituting other erythritol sweetener as you may have trouble with the sweetener giving the fudge a granular texture if you need to use a larger quantity to achieve the same level of sweetness.


Pyure is twice as sweet as sugar. If your sweetener measures cup for cup like sugar, you would have to double the amount to get the same sweetness level. Erythritol won’t stay in solution at this level and is likely to crystallize out as the fudge cools. 


Other, more soluble sweeteners may work in this recipe, but I haven’t tested them. 


Final words

If you’re a chocolate lover, this keto chocolate  fudge will make a special holiday treat, Valentine’s day gift, or simply a delicious treat. Enjoy!
