Keto Fudge
If you're following the keto lifestyle and you have a sweet tooth you're going to want to make a batch of this keto fudge to keep in the refrigerator or freezer.
It's super sweet and just one square of this keto chocolate fudge will curve any cravings you have for sweets.
The thing that I love most about this keto fudge recipe is that it's super simple and you don't need any fancy equipment or a candy thermometer to make it.
This recipe can easily be made using a microwave but if you don't have a microwave you can heat up the butter and keto chocolate chips on the stove.
Keto Fudge Ingredients
Butter - The butter adds flavor and fat, while creating a smooth and creamy keto fudge.
Sugar Free Chocolate Chips - You can use whichever sugar free chocolate chips you like to make this keto fudge, but we like Lily's.
Powdered Sweetener - We like to use Lakanto powdered sweetener and Swerve powdered sweetener. It's not recommended to use granulated sweetener, it doesn't work the same way.
Heavy Whipping Cream - Helps add flavor, and fat, while working with the butter to keep this low carb fudge smooth and creamy. Like melt in your mouth creamy.
Vanilla Extract - For a touch of flavor. You can also switch the vanilla out with peppermint extract during the holidays to make a keto peppermint fudge.
If you have any questions about the ingredients in this low carb fudge recipe, please leave them in the comments below.

The base keto fudge recipe is amazing as is but sometimes you want something a little extra. Any of the options above are delicious add-ins.
How to make keto fudge
- Melt butter and sugar free chocolate chips in the microwave for one minute. If you don't have a microwave, you can melt them together on the stove.
- Stir until all chocolate chips are melted. Heat for an additional 30 seconds if needed.
- Add in powdered sugar-free sweetener, heavy whipping cream, and vanilla extract.
- Stir until combined. If desired, add your add-ins (listed above) and stir.
- Spoon keto fudge into a parchment paper lined 4X4 square dish. Refrigerate for 1 hour, or until firm.
- Remove the parchment paper from the dish and using a sharp knife, cut into 25 squares.
NOTES:
You will need to wait until the fudge is completely solid before cutting it.
You can cut this keto chocolate fudge into smaller or larger pieces depending on your preference. Just make sure to divide the total macros and carbs by the number of pieces you cut.
These numbered steps match the numbered photos above and are for illustration purposes. For the complete list of ingredients and instructions, please see the recipe below.
How to store keto fudge
This keto chocolate fudge is basically a refrigerator fudge. It melts easily and needs to be stored in the refrigerator or freezer.
It can last up to 2 weeks in the refrigerator or up to 6 months in the freezer.
Make sure to store this keto fudge in an airtight container to prevent freezer burn.
Freezing Keto Fudge
We love to freeze this keto fudge. We recommend cutting it into pieces before you freeze it, that way you can pull them out one at a time.
The fudge is very firm, but still delicious frozen.
Store this keto fudge in the freezer for up to six months.
Low Carb Chocolate Chips
Lily’s makes a low carb keto chocolate chip.
Explorado Market – Keto Chocolate Chips.
Lakanto Sugar Free Chocolate Bars.
90% dark chocolate, chopped.
We have a recipe for homemade sugar free chocolate chips. They use similar ingredients and can be used to make fudge. (coming soon, hang tight).
Any sugar free chocolate sweetened with Stevia and/or Erythritol (both sweeteners are a zero carb sugar sweetener) work in this keto fudge recipe.
Dairy Free Keto Fudge
If you need a dairy-free keto fudge recipe make sure to use dairy-free keto friendly chocolate chips or chocolate and coconut oil.
You can melt the coconut oil and chocolate chips together the same as you would the butter.
You can also use a dairy-free butter. Because this is a refrigerator fudge, it will solidify when you chill it.
Make sure to store this keto chocolate fudge in the refrigerator or freezer otherwise it will melt.

This fudge is SO VERY GOOD, that is does NOT TASTE LIKE IT DOESNT CONTAIN SUGAR !! My Diabetic customers ask me if it is REALLY SUGAR FREE !! I've added pecans, walnuts, chopped fresh cherries,and peanut butter.v
Djenifer
Delicious and so easy. I added walnuts. The possibilities are endless. Next time I will add a little sea salt to the top. Also I’m thinking about changing the vanilla to a teaspoon of coffee or a different extract. Or some hazelnuts.

I am so glad you like it. Thank you for taking the time to stop back by and let me know.

OMG, this is amazing. It literally is just like regular fudge, super easy and if you are a regular keto cook you already have all these things in your pantry so it's easy to make without really off the wall ingredients or extra trips to the store. I'm going to Disney World soon and I have a massive weakness for the fudge... not a problem now. Just make and bring a few recipes of this and problem solved.

I am so glad you like it. Have a great time at DW!

How many carbs, w/0 nuts per piece
Four Score Living
It depends on what sugar free chocolate chips you use, but it's about 1 net carb per piece.
Sue
How much coconut oil would I use if substituting for the heavy cream?
Four Score Living
Hi Sue, I'm not sure. I haven't tried subbing the cream out with coconut oil.
Nancy Rebehn
How many carbs not net carbs? Diabetics don’t count net carbs.
Four Score Living
The carbs are listed right before the net carbs, 1 gram of carbs per piece. Please double check the carb count based on the sugar free chocolate chips you use, it can vary by brand.
JustMe
Has anyone tried this with allulose or BochaSweet?
shayna
Is this really meant for a 4x4 pan and yields 25 pieces? Are they really small? I made this and used an 8x8 pan. Please advise..thanks! It taste great, just wanted to clarify the pan size.
Four Score Living
It depends on how thick you like the fudge. I used a 4x4 when I developed it, but I like the fudge a little thicker. You can certainly use any size pan that you like. I hope that helps.
Rona Shacham
Since i dont have bought chocolate chips and i need to use a bar (chopped) how much of the chocolate bar should i use? If i cut it in different sizes a cup measurement cant really help me.. can you give me a hint on the weigh?
Four Score Living
You can use the same amount called for in the recipe, 8 oz.
Candi Carey
I was shocked at how simple this amazing recipe was. It is really tasty, I didn't try any add ins the first time, and it was still delicious. I did use an electric mixer after adding the swerve vanilla and heavy whipping cream to make sure it had a smooth consistency, and it is amazing!
Lee Ann
This fudge is so very good, I’m not a diabetic I am living the keto lifestyle. I was wondering what is a serving size of this recipe.
Four Score Living
You can cut the fudge into how many servings you like, just divide the calories and macros by that number. We like to make 1" pieces, which is about 25 servings.
Theresa W
Made as directed. I made it with a cup of chocolate chips. And used an old fashioned metal ice cube tray to cool in. Tasty. Also tossed in a handful of walnuts at the end. Thanks for the recipe.
Loreen Broderick
This was very easy, surprisingly tasty and the texture was just like traditional fudge. It had the very slightest artificial sweetener aftertaste, barely noticeable but next time I will use a little extra vanilla extract or the peanut butter mix in to counteract. I definitely will make this again.

Fran
Is it really a 4x4 pan? I've never heard of one
Four Score Living
We use a 4 x 4 glass container that comes with a lid. You can use something similar, or double the recipe and use a 8 x 8 pan.

When you say powdered sweetener, do you meen like Monk fruit or do you mean white like white powdered confectionery sugar?
Four Score Living
Powdered sweetener like Swerve, or Lakanto powdered sweetener. We hope that helps.

Sherry
Why did butter settle on top? I doubled recipe and finished. Put into refrigerator and peep on it after 15 mins. Melted butter is now on top. ??
Four Score Living
Hi Sherry,
If you melted everything together and mixed it well, then the main reason butter might settle on top is that the fudge mixture got to hot.

This is Amazing! Works incredibly well in a silicone bites tray of 24 measuring out 18 grams per square with 23 grams left for hubby to enjoy a "big bite". I took pictures of course but don't see where to share since I don't tock, tweet or fb. So easy & sinfully delicious! Thank you for sharing 😀
