6-Ingredient Chocolate Keto Fudge (Sugar-Free, Low Carb)

By Bree

Today I’m going to be sharing a chocolate keto fudge recipe that incredibly satisfying and decadent, low carb and sugar-free! It fulfills all the deep chocolate fudge cravings that you’re use to, but in a keto-friendly way.

Easy 6-ingredient keto fudge.

How to Make Chocolate Keto Fudge

  • Prepare your baking pan. I recommend an 8×4 loaf pan for this. Line it with some parchment paper for easy transferring.
  • Simmer the butter mixture. Add the butter, sweetener, and heavy cream to a saucepan. Simmer for about 15 minutes over medium heat, stirring occasionally, until the mixture has thickened. Make sure not to burn the butter.
  • Add the chocolate. Stir slowly and gently until the chocolate melts.
  • Finish it all off. Pour the chocolate mixture into the prepared loaf pan and sprinkle the top of it with either chopped walnuts or pecans.
  • Refrigerate. Refrigerate the fudge overnight, or for a minimum of 6 hours.
  • Serve. Cut into squares and serve!

Can I Use Milk Chocolate Chips Instead for Keto Fudge?

While there’s nothing stopping you from using milk chocolate chips instead when making this recipe, if you do so, you’re going to end up with fudge that isn’t exactly keto friendly.

The reason why this recipe uses dark chocolate chips is because they contain way less sugar than milk chocolate chips–and for more nutrients as well… They also provide some great benefits for your heart health thanks to their fiber and monounsaturated fat content. (1)

So yes, you can use milk chocolate chips and end up making some pretty good fudge bars. But if you want to keep the recipe as keto as possible, then just stick with dark chocolate chips.

Here are some of my favorite keto friendly toppings to add to this fudge:

  • Chopped nuts (walnuts, pecans, almonds)
  • Cream cheese frosting
  • Shredded coconut flakes
  • All-natural peanut butter
  • Chia seeds

Why Is My Sugar-Free Fudge Grainy?

Homemade sugar-free fudge turning out kind of grainy is actually a rather common problem. It could be caused by not properly dissolving all of your granulated sweetener before melting down the fudge mixture. Other possible causes include the fudge not being beaten long enough, or it could be something as simple as the fudge mixture not having enough fluid or fat to properly dissolve the sweetener.

If I Make a Mistake, Can I Melt the Same Fudge Again and Remake It?

Continuing on from the point about grainy fudge from above leads us directly into another one of the most commonly asked questions that I get in regards to making homemade fudge: can you melt the fudge again and remake it if you’ve made a mistake?

Luckily, this is absolutely possible, and is in fact the quickest way to solve the issue of grainy fudge. Simply put your grainy fudge back into the pot with a bit of extra heavy cream and water, and then melt it back down to a liquid state.

Once you start to reheat it, ensure that you go slowly to begin with, making sure that the fudge mixture goes completely smooth before you bring it to a boil again.

My Keto Fudge Isn’t Setting Properly – What Do I Do?

The most common reason why homemade keto fudge doesn’t properly set is because you’ve made a fudge mixture that’s too thick. Now, this isn’t necessarily a huge issue, as thick fudge makes for a great sauce to use with ice cream. On the other hand, if you would prefer to thin your mixture out a bit, you can simply add a bit more heavy cream and reheat the fudge until it reaches your desired consistency.

Can I Make a Dairy-Free Version of Keto Chocolate Fudge?

The reason why this particular keto fudge recipe comes together so well is that all of the ingredients have been carefully chosen in order to make fudge that doesn’t just taste great, but it’s also a fantastic low carb treat option as well.

You can use coconut cream instead of heavy cream and ghee instead of regular butter.

The Best Way to Store Keto Fudge

To store your fudge, you’ll first want to cut it into squares. Then arrange all of the squares over top of wax paper, making sure to wrap the edges so that they’re covered.

Next, cover the wrapped keto fudge in aluminum foil and then place in an airtight container. The fudge will keep like this for up to 2-3 weeks.

You can also freeze the chocolate fudge by wrapping it like this and storing it in a freezer-safe container. You can simply thaw it out in the fridge overnight when you’re ready to eat it.

    • Definitely! It will be a little less rich, but should still taste really good 🙂

  1. Easy to prepare and ooh soo good 😋 Everyone from my keto to non-keto friends loved it!! Already made several batches and on one I forgot to add the sweetener and still was delicious lol. Plus another batch added peanut butter & once again did not fail. Thanks for an amazing recipe just love it

  2. Hi Bree,
    I just got done making your fudge. We can’t wait to TASTE it…😋
    I used the “Lakanto, Monkfruit sweetener” I put it in a coffee grinder so it would not be so grainy. It was all so easy to make. The only problem I had I chopped up the choc. so it would melt in the cream once I took it off the stove after the 15 min. of stirring. It was grainy
    😔 so I put the whole pot choc. & all on very low heat. Stirred
    all until the choc. finally became smooth. I was very pleased/happy & can’t wait to try it out 😋😋😋.
    I truly have NO doubt that it’s going to be DELICI😋S…
    Thank you so much for sharing
    your great talents in the kitchen. I was looking at some of your other recipes. 😋H!
    Wow! I can’t wait to dig into them. I will give you the HONEST verdict tomorrow.
    You & your family take care & be SAFE! 😷🇺🇸🎉💥🎆👍😁
