Chocolate Hazelnut Fudge – Sugar-Free Dream
Ingredients
Method
- Line an 8×8 square pan with parchment or waxed paper, then lightly grease the paper.
- Pour the condensed milk into a medium saucepan over medium-low heat, stirring until it just begins to simmer, then remove from heat.
- Add the chocolate chips and keto Nutella, let sit for a few minutes to melt, then whisk to combine until smooth.
- Add the sweetener and hazelnut extract, stir until smooth, then stir in about two-thirds of the chopped hazelnuts.
- Spread the mixture evenly in the prepared baking pan and sprinkle with the remaining chopped hazelnuts.
- Refrigerate for 3 to 4 hours to allow the fudge to firm up completely.
- Remove the fudge from the pan by lifting the edges of the paper and set it on a cutting board.
- Use a large sharp knife to cut the fudge into 16 uniform bars.
Notes
– If your fudge mixture seems too thick to spread easily, gently warm it over very low heat for a minute or two, stirring constantly, until it’s more pliable. Be careful not to overheat, as this can affect the texture.
– Storage: Store the fudge in an airtight container in the refrigerator for up to 2 weeks, or freeze for up to 2 months. Thaw in the refrigerator before serving. If you notice any oil separation, it’s normal for keto treats; just dab it gently with a paper towel. Nutrition information is an estimate, calculated automatically.

Pro tips
- For the cleanest cuts, ensure your fudge is thoroughly chilled (3-4 hours minimum or even overnight) before slicing. Dip your knife in hot water and wipe clean between each cut for perfectly smooth edges.
