Prep and Cook time
- Planning: 20 minutes
- Cooking: 30 minutes
- Cooling: 15 minutes
- Total Time: 1 hour 5 minutes
Yield
12 generous square servings
Difficulty Level
Medium – Ideal for bakers familiar with chocolate tempering and folding techniques but approachable for passionate home cooks.
Ingredients
- 1 cup unsalted butter, cut into cubes
- 8 oz (225g) high-quality dark chocolate (70% cocoa), chopped
- 1 ½ cups granulated sugar
- 3 large eggs, at room temperature
- 2 tsp pure vanilla extract
- ¼ cup Frangelico hazelnut liqueur
- 1 cup all-purpose flour, sifted
- ½ tsp fine sea salt
- 1 cup toasted hazelnuts, roughly chopped
- ½ cup Dutch-processed cocoa powder
Instructions
- Preheat your oven to 350°F (175°C). Line an 8-inch square baking pan with parchment paper,allowing excess to hang over the sides for easy removal.
- Melt the butter and dark chocolate together in a heatproof bowl over simmering water (double boiler method), stirring gently until smooth and glossy. Avoid overheating to maintain a silky consistency.
- Remove from heat and whisk in the granulated sugar until fully incorporated to create a luscious, shiny batter.
- Beat eggs into the mixture one at a time, ensuring full integration before adding the next. Stir in vanilla extract and the ¼ cup of Frangelico liqueur to infuse that signature nutty depth.
- In a separate bowl, sift together the flour, cocoa powder, and sea salt.
- Gently fold the dry ingredients into the wet chocolate mixture using a spatula. do not overmix-just combine until no flour streaks remain. This keeps the brownies tender and moist.
- Fold in the toasted hazelnuts, reserving a small handful for topping.
- Pour the batter evenly into the prepared pan and sprinkle the reserved hazelnuts over the top for a toasted crunch.
- Bake for 28-32 minutes. Check doneness by inserting a toothpick-it should come out with moist crumbs but not wet batter.
- Cool completely in the pan before lifting out using the parchment paper. Cut into 12 squares for ideal portions.
Tips for Success
- Nutty variations: Substitute half the hazelnuts with toasted almonds or walnuts for a unique flavor twist without losing that crunch.
- Frangelico balance: If preferred, reduce liqueur to 2 tablespoons for a subtler profile, or for a boozy boost, gently fold in an extra tablespoon after baking.
- Moisture Mastery: Avoid overbaking to keep the brownies fudgy inside; ovens vary, so start checking 3 minutes before the minimum time.
- Make-ahead: store in an airtight container at room temperature for up to 3 days, or freeze cut brownies wrapped tightly for up to 1 month.
- Chocolate quality: Use the best-quality dark chocolate you can find; it hugely influences the depth and richness.
