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.

NOTES:

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.
Best,

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

How many carbs, w/0 nuts per piece
Chrystal
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?
Chrystal
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.
Chrystal
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.
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.
Chrystal
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?
Chrystal
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.
Chrystal
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.
