When chocolate cravings strike, nothing hits the spot like rich, smooth fudge. 

This keto version delivers all the indulgence you want, without the sugar and carbs. Easy to make, melts in your mouth, and works with both dairy and dairy-free options.

Why You’ll Love This Recipe

  • Quick & easy: Just a few steps and minimal ingredients.

  • Rich chocolate flavor: Made with unsweetened chocolate and cocoa for depth.

  • Smooth texture: Creamy and smooth with every bite.

  • Low-carb: No sugar, keto-friendly, and satisfying.

  • Versatile: Can be made with cream or coconut cream.

Ingredients (What You’ll Need)

  • Vanilla & salt: simple, but they round out the flavor and make the chocolate shine.

  • Sweeteners: a mix of powdered erythritol (for structure) and allulose (for smoothness). Together, they keep the fudge firm yet creamy.

  • Cocoa powder:  Dutch-processed works best for a darker, smoother taste.

  • Collagen peptides:  optional, but they add chew and a little nutrition boost.

  • Butter:  gives richness and helps the fudge set. Coconut oil can be swapped in.

  • Unsweetened chocolate: stick to 100% cacao; it thickens the mixture and brings bold flavor.

  • Almond milk:  keeps the base from being too heavy. Hemp or other nut milks work too.

  • Heavy cream: the foundation of the recipe. Coconut cream is the dairy-free alternative.

Step-By-Step Instructions

1. Set the fudge

Line a pan with parchment paper so it’s ready to go. This makes the later steps easier and keeps cleanup simple.

2. Thicken the cream

Now make the base: add cream, almond milk, butter, and sweeteners to the saucepan. Simmer gently until it reduces by about a third. This creates a condensed foundation.

3. Mix in the flavor

In a saucepan, once the base is ready, whisk in cocoa powder, collagen, vanilla, and salt. You’re looking for a glossy, thick mixture.

4. Melt the chocolate

Remove from heat and stir in the chopped unsweetened chocolate. Whisk slowly until it’s melted and silky smooth.

5. Slice & enjoy

After chilling at least 6 hours (overnight is even better), lift the fudge out of the pan. Warm your knife under hot water for clean cuts, then slice into squares.

 

Tips for Perfect Fudge

  • Storage: Best kept chilled in the fridge. Softens if left at room temp for too long.

  • Use quality chocolate: Brands like Guittard or Ghirardelli melt smoothly and give better flavor.

  • Rescue trick:If the mixture seizes, beat with a hand mixer on low until it comes back together.

  • Clean slices: Heat your knife before cutting.

  • No collagen? Add 1 tbsp cocoa powder + 1 tbsp powdered sweetener instead.
