Keto Fudge Recipe

Experience the indulgence of fudge without worrying about your blood sugar levels. This keto-friendly fudge recipe offers the richness and creamy texture of traditional fudge, enhanced with a zero sugar caramel swirl, ensuring you can enjoy a guilt-free treat anytime.

Fudge has always represented a luxurious treat reserved for special moments. After discovering the variety of fudge options available, the desire for a healthier, keto-compatible version grew. The result is a sugar-free delight that doesn’t compromise on taste or texture.

Sugar Free Fudge Recipe

This recipe utilizes unsweetened creamy almond butter as its foundation, crucial for achieving the iconic fudge consistency. The choice of almond butter will influence the final taste of the fudge, so select one that you enjoy.

Perfect Fudge Texture

For the best texture, enjoy this fudge straight from the freezer. Not only does it taste fantastic, but freezing also extends its shelf life. However, it’s so delicious, it’s unlikely to last very long!

Clean Keto Ingredients Needed:

  • 1/2 cup Butter (we use salted Kerrygold)
  • 1/3 – 1/2 cup Lakanto Brown Sugar
  • 1 cup Premium Almond Butter
  • 1 tsp Vanilla Extract
  • 2 Tbsp High-Fat Cocoa Powder, sifted
  • 1/4 cup Zero Sugar or Keto Caramel Sauce
  • Sea Salt Flakes, optional

Tell me more about Allulose & Erythritol:

In this recipe, you’ll be consuming a few alternative sweeteners that do not raise blood sugar. In fact, Allulose is a ZERO on the glycemic index while Eyrthritol is only a 1. If you’re trying to manage your blood sugar, these sweeteners will NOT raise your blood sugar.

Here are a few blog posts on this site that will help clear up confusion about alternative sweetners:

What is Keto Caramel Sauce?

This recipe incorporates alternative sweeteners that do not impact blood sugar levels, making it perfect for those managing their intake. Both Allulose and Erythritol are used due to their minimal effect on blood sugar, with Allulose being a ZERO on the glycemic index and Erythritol only a 1.

Keto Fudge Recipe

Salted Caramel Swirl Fudge {sugar-free}

Yield: 18 pieces
Prep Time: 10 minutes
Cook Time: 5 minutes
Chill Time: 45 minutes
Total Time: 1 hour


  • 1/2 cup Butter (we use salted Kerrygold)
  • 1/3 - 1/2 cup Lakanto Brown Sugar, see notes
  • 1 cup cardnl Premium Almond Butter
  • 1 tsp Vanilla Extract
  • 2 Tbsp cardnl High-Fat Cocoa Powder, sifted
  • 1/4 cup cardnl Salted Caramel Sauce
  • Sea Salt Flakes, optional


    1. Line a 1lb loaf pan with parchment paper, leaving some flaps overlapping. Set aside. 
    2. Bring butter and Lakanto to a boil over medium-low heat. Stir constantly with a silicone spatula, scraping the sides to keep it from burning. Let it bubble and foam up, and continue stirring until the foaming starts to recede and the mixture thickens. Remove from heat. 
    3. Stir in the almond butter and vanilla. Remove 1/2 cup and place it in a heat safe bowl or glass measuring cup. Set aside. 
    4. Add the cocoa powder to the rest of the fudge and stir it in completely until smooth. I prefer using a silicone spatula for this part. 
    5. Add the caramel sauce to the 1/2 cup fudge you set aside. Stir until completely combined and smooth. 
    6. In the prepared loaf pan, pour the chocolate fudge in the bottom, spreading to fill all sides and corners. 
    7. Gently pour the caramel fudge over the top. Use a butter knife to swirl the two together without completely mixing them. Sprinkle salt flakes on top, if desired. 
    8. Place in the freezer for at least 30-45 minutes, or longer if needed, until completely firm. 
    9. Holding the parchment paper flaps, lift the fudge out of the pan and cut into even 1.5" squares with a sharp, hot knife. Run the knife under hot water every few slices, if needed, to keep edges clean and crisp. 
    10. Store fudge in a tightly sealed container in the fridge (up to 2 weeks) or freezer (up to 6 months). We prefer eating this straight out of the freezer for best texture/firmness.


  • If you use the full 1/2 cup of Lakanto brown Sugar, this will be a pretty sweet fudge. Use 1/3 cup to tone it down a little.
  • I don't recommend subbing with Lakanto Golden, it doesn't yield the same creamy results.
  • Adding salt flakes will help cut the sweetness a little and enhance the flavor. Taste the fudge first to see if you want the added salt.
