Ingredients

  • 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
  • 2/3 cup toasted hazelnuts, chopped

Instructions

  1. Step 1: Line an 8×8 inch square pan with parchment or waxed paper. Lightly grease the paper to prevent sticking.
  2. Step 2: Pour the sugar-free condensed milk into a medium saucepan and heat over medium-low heat. Stir occasionally until it just begins to simmer, then remove from heat.
  3. Step 3: Add the sugar-free chocolate chips and homemade sugar-free Nutella to the warm condensed milk. Let it sit for a few minutes to allow the chocolate to melt, then whisk until smooth.
  4. Step 4: Stir in the allulose sweetener, collagen protein powder, and hazelnut extract until fully combined. Then fold in about two-thirds of the chopped toasted hazelnuts.
  5. Step 5: Spread the mixture evenly into the prepared pan. Sprinkle the remaining chopped hazelnuts on top for added crunch.
  6. Step 6: Refrigerate the fudge for 3 to 4 hours, or until firm. Once set, lift the fudge out using the edges of the parchment paper and place on a cutting board.
  7. Step 7: Use a large sharp knife to cut the fudge into 16 bars. Serve chilled and enjoy!

Tips & Variations

  • For extra richness, use high-quality sugar-free dark chocolate chips.
  • Substitute hazelnut extract with vanilla extract if you prefer a milder nutty flavor.
  • Try adding a pinch of sea salt on top before refrigerating for a salted caramel twist.
  • Make it nut-free by omitting the chopped hazelnuts and using almond extract instead of hazelnut extract.

Storage

Store the fudge bars in an airtight container in the refrigerator for up to two weeks. For longer storage, freeze them for up to three months. To serve, let thaw in the fridge or at room temperature for a few minutes.

FAQs

Can I use regular sweetened condensed milk instead?

Regular sweetened condensed milk will add sugars and affect the keto-friendly nature of the fudge. Using sugar-free condensed milk keeps it low-carb and suitable for sugar-restricted diets.

How do I toast hazelnuts at home?

Spread hazelnuts on a baking sheet and toast in a 350°F (175°C) oven for about 10 minutes, stirring halfway through, until golden and fragrant. Let them cool 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.
