    The Ingredients

    To embark on this culinary adventure, gather the following ingredients:

    For the Blondies:

    • 1 cup unsalted butter
    • 2 cups all-purpose flour
    • 1 teaspoon baking powder
    • 1/2 teaspoon salt
    • 1 cup dark brown sugar
    • 1/2 cup granulated sugar
    • 2 large eggs, at room temperature
    • 2 teaspoons pure vanilla extract
    • 1 cup dark chocolate chunks
    • 1/2 cup chopped hazelnuts

    For the Brown Butter:

    • 1/2 cup unsalted butter

    Let’s Get Baking

    Preparing the Brown Butter

    Begin by preheating your oven to 350°F (175°C). In a small saucepan over medium heat, melt the 1/2 cup of unsalted butter for the brown butter. Swirl the pan occasionally and continue cooking until the butter turns golden brown and emits a nutty aroma. Be vigilant as brown butter can quickly turn from golden to burnt. Once achieved, remove the butter from heat and allow it to cool slightly.

    Mixing the Blondie Batter

    In a large mixing bowl, whisk together the all-purpose flour, baking powder, and salt. Set aside. In another bowl, combine the dark brown sugar, granulated sugar, and the cooled brown butter. Mix until well combined and the sugar has dissolved into the butter.

    Next, beat in the eggs, one at a time, followed by the pure vanilla extract. Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix as it can result in tough blondies.

    Adding the Chocolate and Hazelnuts

    Now comes the best part – the mix-ins! Gently fold in the dark chocolate chunks and chopped hazelnuts until evenly distributed throughout the batter. The combination of the rich chocolate and crunchy hazelnuts adds a delightful texture to the blondies.

    Baking the Blondies

    Pour the batter into a greased 9×13 inch baking dish, spreading it out evenly with a spatula. Place the dish in the preheated oven and bake for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with a few moist crumbs.

    Letting Them Cool (If You Can Resist)

    Once baked to perfection, remove the blondies from the oven and allow them to cool in the pan for at least 15 minutes before slicing. This waiting period allows the blondies to set and ensures that each bite is filled with gooey goodness.

    Serving and Enjoying

    Now comes the moment you’ve been waiting for – indulging in your freshly baked Dark Chocolate Hazelnut Brown Butter Blondies! Cut them into squares of your desired size and serve them alongside a glass of cold milk or a scoop of vanilla ice cream for the ultimate indulgence.


    In conclusion, these Dark Chocolate Hazelnut Brown Butter Blondies are a heavenly treat that combines the richness of dark chocolate, the nuttiness of hazelnuts, and the irresistible flavor of brown butter. Whether you’re treating yourself to a solo indulgence or sharing them with friends and family, these blondies are sure to impress. So, roll up your sleeves, preheat your oven, and get ready to embark on a culinary adventure that will leave you craving for more.


    1. Can I use milk chocolate instead of dark chocolate for this recipe? Absolutely! Feel free to customize the recipe according to your preference. Milk chocolate will impart a sweeter flavor profile to the blondies.

    2. Can I substitute the hazelnuts with another type of nut? Certainly! You can swap the hazelnuts for almonds, pecans, or walnuts, depending on your taste preferences or any allergies.

    3. How should I store the leftover blondies? To keep your blondies fresh, store them in an airtight container at room temperature for up to 3 days. For longer storage, you can freeze them for up to 1 month.

    4. Can I double the recipe to make a larger batch? Absolutely! Simply double the ingredients to make a larger batch of blondies. Just be sure to adjust the baking time accordingly and use a larger baking dish if necessary.

    5. Can I omit the brown butter if I don’t have it on hand? While brown butter adds a unique flavor to the blondies, you can certainly omit it if you don’t have it on hand. Simply substitute it with an equal amount of melted unsalted butter for a delicious alternative.
