Ingredients
This recipe makes approximately 16 delicious dessert squares.
-
For the Hazelnut Crust:
- 1 ½ cups (about 150g) graham cracker crumbs (from about 10-12 full sheets)
- ¼ cup (50g) granulated sugar
- ½ cup (113g) unsalted butter, melted
-
For the Dark Chocolate Hazelnut Filling:
- 1 (14-ounce) can (397g) sweetened condensed milk
- 1 ½ cups (255g) dark chocolate chips (60-70% cacao recommended)
- ¼ cup (56g) unsalted butter
- 1 teaspoon vanilla extract
- ½ teaspoon salt
- 1 ½ cups (about 180g) chopped toasted hazelnuts, divided
-
For Garnish (Optional):
- 2 tablespoons extra chopped toasted hazelnuts
- 1 ounce dark chocolate, shaved or finely chopped
Step-by-Step Instructions
-
Step 1: Prepare Your Pan and Oven
Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides. This makes it much easier to lift the squares out later. Small tip: Crinkle the parchment paper slightly before pressing it into the pan; it helps it fit better.
-
Step 2: Make the Hazelnut Crust
In a medium bowl, combine the graham cracker crumbs and granulated sugar. Pour in the melted butter and stir until the crumbs are evenly moistened. Press this mixture firmly and evenly into the bottom of your prepared baking pan. Set aside.
-
Step 3: Prepare the Dark Chocolate Mixture
In a medium saucepan or microwave-safe bowl, combine the sweetened condensed milk, dark chocolate chips, and ¼ cup unsalted butter. Heat over low heat, stirring constantly, until the chocolate and butter are fully melted and the mixture is smooth and glossy. If using a microwave, heat in 30-second intervals, stirring well after each, until smooth.
-
Step 4: Flavor the Filling
Remove the chocolate mixture from the heat. Stir in the vanilla extract and salt. Then, fold in 1 cup of the chopped toasted hazelnuts. Save the remaining ½ cup of hazelnuts for later.
-
Step 5: Assemble the Squares
Pour the warm dark chocolate hazelnut filling evenly over the prepared graham cracker crust. Gently spread it to the edges of the pan using a spatula. Make sure the layer is consistent for even baking.
-
Step 6: Bake to Perfection
Place the baking pan in the preheated oven. Bake for 25-30 minutes, or until the edges are set and the center is just slightly jiggly. Be careful not to overbake, as this can make the squares dry. Small tip: The squares will continue to set as they cool.
-
Step 7: Cool and Chill
Once baked, remove the pan from the oven and place it on a wire rack to cool completely at room temperature. This will take at least 1-2 hours. For the best texture and clean cuts, transfer the pan to the refrigerator and chill for at least 2 hours, or preferably overnight.
-
Step 8: Cut and Serve
Once thoroughly chilled, use the parchment paper overhang to lift the entire slab of squares out of the pan. Place it on a cutting board. Using a sharp knife, cut into 16 even squares. Garnish with the remaining 2 tablespoons of chopped toasted hazelnuts and dark chocolate shavings, if desired. Serve and enjoy!
Tips & Variations
- Gluten-Free Option: Easily make these squares gluten-free by using gluten-free graham crackers for the crust. Alternatively, you can make a nut-based crust by finely grinding almonds or pecans and mixing them with melted butter and a touch of sugar.
- Vegan/Vegetarian Option: To make these squares vegan, use dairy-free dark chocolate chips, a plant-based sweetened condensed milk (often made from coconut or oat milk), and vegan butter. Ensure your graham crackers are also vegan-friendly. The recipe is naturally vegetarian.
- Added Nutrients: While a dessert, you can boost the nutritional profile slightly. Stir a tablespoon of chia seeds or ground flaxseeds into the chocolate filling along with the hazelnuts for extra fiber and omega-3s. Remember, hazelnuts themselves offer healthy fats and protein!
- Spicy Kick: For an intriguing flavor twist, add ¼ to ½ teaspoon of cayenne pepper or chili powder to the dark chocolate mixture. The subtle heat beautifully complements the rich chocolate and nutty hazelnuts.
- Flavor Variations: Experiment with different flavors! Add 1 teaspoon of orange zest to the filling for a chocolate-orange delight, or a teaspoon of instant espresso powder to deepen the chocolate flavor. You can also use a mix of milk and dark chocolate chips for a milder taste.

Health Benefits
While these are dessert squares, the main ingredients offer some lovely benefits!
- Dark Chocolate: High-quality dark chocolate (especially 70% cacao or higher) is packed with powerful antioxidants called flavonoids. These compounds can help protect your cells from damage, support heart health, and may even improve brain function. It can also be a mood booster, thanks to compounds that stimulate endorphin production.
- Hazelnuts: Hazelnuts are a nutritional powerhouse! They are an excellent source of healthy monounsaturated fats, which are good for heart health. They also provide a good amount of dietary fiber, promoting digestive health and satiety.
- Vitamins and Minerals: Hazelnuts are rich in Vitamin E, a potent antioxidant, and essential minerals like manganese, copper, and magnesium. These nutrients play crucial roles in bone health, energy production, and nerve function.
- Balanced Indulgence: Enjoying a treat like this in moderation can be part of a balanced lifestyle. The natural fats in hazelnuts and the antioxidants in dark chocolate contribute to a more satisfying and beneficial indulgence compared to highly processed sweets.
Serving Suggestions
- Serve these decadent squares with a hot cup of coffee, espresso, or a soothing herbal tea for a perfect afternoon treat.
- Elevate the experience by serving a square alongside a scoop of vanilla bean ice cream or a dollop of freshly whipped cream.
- For a touch of freshness, pair them with a small bowl of fresh raspberries or sliced strawberries; the tartness beautifully complements the rich chocolate.
Storage Tips
These Dark Chocolate Hazelnut Dessert Squares keep wonderfully! Store them in an airtight container in the refrigerator for up to 5 days.

Thaw frozen squares in the refrigerator overnight or at room temperature for about an hour before enjoying.
