Fudgy, moist, ooey gooey Brown Butter Blondies with roasted hazelnuts and dark chocolate chunks. These delicious blondies are made with pure white chocolate and have so much rich caramelized flavor.
Immediately pour the browned butter into a clean bowl and let it cool for 2 minutes so it is not boiling hot, then add the chopped white chocolate. Stir until the chocolate is completely melted and the mixture is smooth. Set it aside. It does not need to be completely cooled to use in the recipe.
Make the blondie batter. Combine eggs with both sugars and vanilla in a large mixing bowl and whisk vigorously until pale and thick. It should double in volume. You can also use a hand mixer for this step. Mix in salt and then mix in the melted white chocolate mixture. Sprinkle in the flour and fold it in gently. Add dark chocolate chunks and chopped roasted hazelnuts and fold them in evenly.
Spread batter evenly into your prepared pan. Sprinkle a few extra chocolate chunks and hazelnuts over top and then bake for 23-26 minutes until the top is shiny, golden and crackly and the center is still soft. Do not over bake these. Transfer pan to a wire rack and let the blondies cool completely before slicing. Enjoy with a glass of cold milk!
