Ingredients

Scale

Fudge Base

  • 1 cup sugar-free condensed milk
  • 5 ounces sugar-free chocolate chips
  • 1/3 cup homemade sugar-free Nutella
  • 1/3 cup allulose sweetener (or erythritol, or a mix)
  • 1/3 cup collagen protein powder
  • 1 tsp hazelnut extract

Mix-ins and Topping

  • 2/3 cup toasted hazelnuts, chopped

Instructions

  1. Prepare Pan: Line an 8×8 inch square pan with parchment or waxed paper and lightly grease it to prevent sticking.
  2. Heat Condensed Milk: Pour the sugar-free condensed milk into a medium saucepan over medium-low heat. Stir continuously until it just begins to simmer. Remove the saucepan from the heat to avoid burning.
  3. Melt Chocolate and Nutella: Add the sugar-free chocolate chips and homemade sugar-free Nutella to the warm condensed milk. Let the mixture sit for a few minutes to allow the chocolate to melt, then whisk thoroughly until smooth and combined.
  4. Add Sweetener and Flavorings: Stir in the allulose sweetener (or preferred sweetener), collagen protein powder, and hazelnut extract until the mixture is fully smooth. Fold in about two-thirds of the chopped toasted hazelnuts evenly.
  5. Set in Pan: Pour and spread the fudge mixture evenly into the prepared pan. Sprinkle the remaining chopped hazelnuts evenly over the top for added texture and presentation.
  6. Refrigerate to Firm: Place the pan in the refrigerator for 3 to 4 hours to allow the fudge to firm up completely.
  7. Cut and Serve: Use the parchment paper edges to lift the fudge out of the pan. Transfer to a cutting board and slice into 16 bars using a large sharp knife. Enjoy chilled!

Notes

  • Ensure toasting hazelnuts enhances their flavor; toast them in a dry skillet or oven until golden and fragrant before chopping.
  • Use a sharp knife warmed slightly under hot water for cleaner cuts.
  • Store fudge bars in an airtight container in the refrigerator for up to one week.
  • You can customize sweetness by adjusting the amount or type of sweetener.
  • If homemade sugar-free Nutella is unavailable, you can substitute with any sugar-free hazelnut spread.
