Why you'll love this recipe

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 decadent and just one square will curve any cravings you have for sweets.

The thing that I love most about this low-carb 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.

Key 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 recipe, 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 Cream - adds 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 holiday season to make a keto peppermint fudge.

Storage instructions

This recipe 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.

We love to freeze this fudge. We recommend cutting it into pieces before you freeze it, that way you can pull them out one at a time.

Make sure to store, up to 6 months in the freezer, in an airtight container to prevent freezer burn. The fudge is very firm, but still delicious frozen.

Best Chocolate Chips to use

When choosing your chocolate chips, always read the nutrition label and check the ingredients. The darker the chocolate the better, always aim for 70% and up.

Lily’s makes a low carb keto chocolate chip.

Explorado Market – Sugar-free 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 keto chocolate fudge.

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 in the refrigerator or freezer otherwise it will melt.

Expert Tips

Mix by hand - This recipe is so simple there is no need to use a hand or stand mixer. Using those appliances will add air bubbles to your fudge, changing the consistency.

Parchment paper is a must - If not used, your fudge will be truly stuck to your pan. Save yourself the hassle and line the pan.

Powdered sweetener - We mentioned it earlier but its worth saying again. If you use granulated sweetener your fudge will not be smooth and creamy.

Hot knife - When you go to cut your homemade fudge, run your knife under hot water and it will give beautiful clean slices.
