Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 1/3 cups (315.45 ml) heavy whipping cream (or canned coconut cream)
1/3 cup (78.86 ml) almond or hemp milk, unflavored
1/3 cup (63.33 g) powdered sweetener
3 tablespoons granular allulose (or xylitol)
2 tablespoons butter (or coconut oil)
5 oz (141.75 g) unsweetened chocolate, chopped
1/3 cup (78.86 g) collagen peptides
2 tablespoons cocoa powder
1/2 teaspoon vanilla extract
1/4 teaspoon salt

Directions

Line a 9×5-inch loaf pan with parchment or waxed paper and set aside.
In a medium saucepan over medium heat, combine the heavy cream, almond or hemp milk, powdered sweetener, allulose, and butter.
Bring the mixture to a low boil, then reduce heat and simmer for 20–30 minutes, stirring occasionally. The mixture should thicken and reduce by about one-third.
Remove from heat and add the chopped unsweetened chocolate. Let sit for 5 minutes to melt.
Whisk the mixture until smooth and glossy.
Stir in collagen peptides, cocoa powder, vanilla extract, and salt until fully combined.
Pour the mixture into the prepared loaf pan and smooth the top.
Optional: Sprinkle with sea salt or chopped nuts.
Refrigerate for at least 6 hours, or until fully firm.
Slice into 12 squares and serve chilled.

Variations

Dairy-Free Version: Use canned coconut cream and coconut oil instead of heavy cream and butter.
Nut-Free: Choose hemp milk instead of almond milk and omit any nut toppings.
Flavor Twist: Add a drop of peppermint extract or orange zest for seasonal flavor.
Extra Rich: Mix in chopped sugar-free chocolate chips or swirl in almond butter before chilling.
Textured Fudge: Fold in chopped pecans, walnuts, or shredded coconut before pouring into the pan.
Protein Boost: Increase collagen peptides slightly for extra protein without changing the texture.

Storage/Reheating

Store your keto fudge in an airtight container in the refrigerator for up to 10 days.

For longer storage, freeze pieces individually wrapped in parchment and sealed in a freezer-safe bag for up to 2 months. Thaw in the refrigerator before serving.

Do not reheat; serve chilled or at room temperature for best texture.

FAQs

Can I use only one type of sweetener?

Yes, but using a mix of powdered sweetener and allulose (or xylitol) gives a smoother texture and balanced sweetness.

What’s the purpose of collagen peptides?

They add structure and a smooth, creamy consistency while providing protein and health benefits.

Can I use cocoa powder instead of chocolate?

No, cocoa powder alone won’t provide the fat and consistency needed for traditional fudge texture.

Is this fudge suitable for diabetics?

It’s low in carbs and sugar-free, but always consult a medical professional based on individual needs.

Why did my fudge not set?

It may need more time to chill or wasn’t reduced enough during simmering. Make sure the mixture thickens before adding chocolate.

Can I use erythritol instead of allulose?

You can, but erythritol may lead to a slightly gritty texture unless finely powdered.

How long should I chill the fudge?

At least 6 hours in the fridge is recommended for proper firmness, or overnight for best results.

Can I make this recipe without collagen?

Yes, but the texture will be softer and less firm. Consider reducing the cream slightly to compensate.

What type of chocolate is best?

Use high-quality unsweetened chocolate for the richest flavor without added sugars.

Can I double the recipe?

Yes, just use a larger pan or adjust chill time if the layer is thicker.

Conclusion

Keto Fudge is a creamy, chocolate-lover’s dream that fits right into a low-carb lifestyle. With a silky smooth texture, rich flavor, and nourishing ingredients, it’s the perfect way to enjoy a classic treat without the sugar.
