I’ve been making this creamy keto fudge for what feels like forever now. When the chocolate cravings strike and nothing but fudge will do, this is my go-to recipe. And I’ve made both the dairy and dairy-free versions for friends and family.

This recipe has been on my blog since 2013, but I recently found a way to make it even creamier and lower in carbs. And with added nutrition benefits too! How’s that for full service keto recipes?

Of course, there are no shortage of keto fudge recipes here on All Day I Dream About Food. How about some some delicious Keto Rocky Road Fudge made with my sugar-free marshmallows!

Why you must try this recipe

When I was a kid, the easiest way to make fudge was to melt sweetened condensed milk with chocolate chips together. It was a simple as that. Once I created my sugar free condensed milk, I realized I might be able to enjoy keto fudge again.

And things have gotten easier, with so many great keto-friendly products becoming readily available. Using some BochaSweet or allulose in this helps keep the fudge softer, without any residual grittiness.

I started experimenting with adding collagen to recipes, in an effort to improve the texture. It worked so well in my Keto Peanut Butter Fudge that I decided to try it in this recipe too.

I was amazed and delighted with the results. It gives the keto fudge a chewier texture while lowering the carb count. It also helps firm up the mixture so it can stay out at room temperature. This isn’t freezer fudge, my friends. This is the real deal here.

And I’ve provided options to make it entirely dairy-free as well!

Ingredients you need

Top down image of the ingredients for keto fudge, with labels.

Heavy cream OR Coconut milk: You can make this recipe with dairy or without. They both taste spectacular! If you make it dairy-free, be sure to use full fat coconut milk. I love the Native Forest brand because the milk is organic, non-GMO, and sustainably farmed, and because the cans are BPA free.
Two sweeteners: I know it would be simpler if there was just one go-to sweetener that worked in every application. But that is simply not the case with alternative ingredients. I recommend powdered Swerve to help set the keto fudge properly, and some BochaSweet or allulose to help it stay softer and not recrystallize.
Butter OR Coconut oil: This helps the fudge thicken and set properly, and also adds creaminess, so don’t skip it.
Unsweetened chocolate: Make sure to choose chocolate that is 100% cacao, with no sweeteners at all. It is lower in carbs and also helps the fudge thicken and set properly.
Collagen peptides: This is optional, but it does help thicken the fudge and give it a wonderfully chewy quality. And it’s incredibly good for your joints, skin, and hair so I recommend it. You can use unflavored, vanilla, or chocolate collagen in this recipe.
Cocoa powder: I recommend Dutched cocoa powder for a deeper chocolate flavor. Raw cacao powder does not dissolve well for keto fudge.
Pantry staples: Vanilla extract, salt.

Step-by-step directions

1. Thicken the cream: In a medium saucepan over medium heat, bring the heavy cream, sweeteners, and butter to a low boil. Reduce the heat and simmer 20 to 30 minutes, or until the mixture is thickened and reduced by about one third.

2. Add the chocolate: Remove from heat and add the chopped chocolate. Let stand 5 minutes, until melted, then whisk until well combined and mixture is smooth.

3. Whisk until smooth: Whisk in the collagen, if using, the cocoa powder, vanilla extract, and salt until smooth.

4. Chill the fudge: Spread the mixture in a 9×5 inch loaf pan lined with waxed paper or parchment paper. Chill 6 hours until firm and cut into squares.

Recipe tips

Like most keto fudge recipes, this does get a bit soft at room temperature, so it’s best stored in the fridge. However, it can sit out on the counter for several hours if you are serving it to guests.

Unsweetened chocolate is temperamental and can seize when subjected to too much heat. Be sure to remove the hot cream mixture from the heat BEFORE adding the chopped chocolate.

To cut keto fudge into perfect squares, heat up a sharp knife. I like to hold mine over the flame of my gas stove for 5 seconds. You can also run some boiling water from a kettle over the blade.
