Pro Tips
- Toast your hazelnuts in a 350°F oven for 8-10 minutes until fragrant, then rub in a kitchen towel to remove skins — this deepens the nutty flavor exponentially
- Line your pan with parchment paper extending over the edges to create “handles” for lifting the entire fudge block out for perfectly even cutting
- Let the fudge come to room temperature for 10 minutes before slicing, and wipe your knife clean between cuts for those professional-looking edges
- For an extra luxurious finish, drizzle melted dark chocolate over the top and sprinkle with flaky sea salt just before the final chill

Creamy Chocolate Hazelnut Fudge Squares
Ingredients
Method
- Line an 8×8-inch square baking pan with parchment paper, leaving a 2-inch overhang on two sides for easy removal. Lightly grease the parchment with butter or cooking spray.
- In a large microwave-safe bowl, combine the chocolate chips, sweetened condensed milk, chocolate hazelnut spread, and butter. Microwave in 30-second intervals, stirring between each, until completely smooth and glossy, about 2-3 minutes total.
- Stir in the vanilla extract and sea salt until fully incorporated. The mixture should be thick and velvety.
- Fold in the toasted chopped hazelnuts, reserving about 2 tablespoons for topping if desired. Mix until the nuts are evenly distributed throughout.
- Pour the fudge mixture into the prepared pan and spread into an even layer using an offset spatula or the back of a spoon. Tap the pan gently on the counter to release any air bubbles.
- Sprinkle the reserved hazelnuts on top and press them gently into the surface. Dust lightly with cocoa powder using a fine-mesh sieve.
- Cover with plastic wrap and refrigerate for at least 4 hours or overnight until completely firm and set.
- Lift the fudge out using the parchment overhang and place on a cutting board. Using a sharp knife wiped clean between cuts, slice into 25 small squares or 16 larger squares.
- Let the squares sit at room temperature for 5-10 minutes before serving for the best texture and flavor.

Frequently Asked Questions
Can I use a different nut butter instead of Nutella?
Yes, you can substitute with another chocolate hazelnut spread or even smooth almond butter for a different flavor profile, though you’ll lose some of that signature hazelnut intensity. Add an extra tablespoon of cocoa powder if using plain nut butter to maintain the chocolate depth.
How should I store these fudge squares?
Store in an airtight container in the refrigerator for up to 2 weeks, with parchment paper between layers to prevent sticking. They also freeze beautifully for up to 3 months — thaw in the fridge overnight before serving.
Why is my fudge too soft or won’t set properly?
This usually means the mixture wasn’t chilled long enough or the ratios were off. Make sure to refrigerate for at least 4 hours, preferably overnight. If it’s still too soft, pop it in the freezer for 30 minutes before cutting.
Can I make these dairy-free?
Absolutely — swap the sweetened condensed milk for coconut condensed milk and use dairy-free chocolate chips. The texture will be nearly identical, though slightly less creamy.
Storage & Serving
Keep these squares refrigerated in an airtight container for up to 2 weeks, or freeze for up to 3 months with parchment between layers. Serve them straight from the fridge for a firm, fudgy texture, or let them sit at room temperature for 10 minutes for a softer, truffle-like consistency. They’re stunning on a dessert platter alongside fresh berries, make elegant gifts when packaged in small boxes, or serve as a decadent finish to dinner parties with espresso or dessert wine.
These creamy squares prove that the best desserts don’t need to be complicated — just let quality ingredients and a little patience work their magic.
