  • 1/3 cup powdered erythritol (or your preferred keto sweetener)
  • 1/4 cup unsweetened cocoa powder
  • 1/2 tsp vanilla extract
  • Pinch of sea salt

Optional Add-Ins:

  • 1/4 cup chopped nuts (e.g., pecans, almonds, or walnuts)
  • 1 tbsp sugar-free chocolate chips
  • 1/2 tsp almond extract

Instructions

Step 1: Prepare the Pan

  1. Line a small square baking dish (6×6 inches or similar) with parchment paper, leaving some overhang for easy removal.

Step 2: Melt the Butter

  1. In a medium saucepan over medium heat, melt the unsalted butter.
  2. Once melted, reduce the heat to low.

Step 3: Combine Ingredients

  1. Add the heavy cream, powdered erythritol, unsweetened cocoa powder, and sea salt to the saucepan.
  2. Stir continuously with a whisk until the mixture is smooth and well combined.

Step 4: Simmer and Thicken

  1. Allow the mixture to simmer gently for 3–5 minutes, stirring constantly, until it begins to thicken.
  2. Be careful not to let it boil, as this can cause separation.

Step 5: Add Vanilla and Optional Ingredients

  1. Remove the saucepan from heat and stir in the vanilla extract.
  2. If desired, fold in the chopped nuts, sugar-free chocolate chips, or almond extract.

Step 6: Pour and Set

  1. Pour the fudge mixture into the prepared pan, spreading it evenly with a spatula.
  2. Chill in the refrigerator for at least 2 hours, or until the fudge is firm and set.

Step 7: Cut and Serve

  1. Lift the fudge out of the pan using the parchment paper overhang.
  2. Cut into 16 squares and serve chilled or at room temperature.
