Ingredients:

  • 1/2 cup (113g) unsalted butter
  • 3/4 cup (150g) packed light brown sugar
  • 1 large egg (50g)
  • 1 tbsp (15ml) pure vanilla extract
  • 1 cup (125g) all-purpose flour
  • 1/2 tsp (3g) fine sea salt
  • 1/4 tsp (1g) baking powder
  • 3/4 cup (130g) dark chocolate chips
  • 1/2 cup (60g) toasted walnuts or pecans

Instructions:

  1. Place the butter in a saucepan over medium heat. Melt and continue cooking, whisking constantly until the butter foams, clears, and develops small brown specks. Remove from heat immediately once it smells nutty and looks golden brown.
  2. Whisk the brown sugar into the hot browned butter until combined. Add the egg and vanilla extract, stirring vigorously for about 1 minute to create an emulsion.
  3. Sift in the flour, salt, and baking powder. Use a spatula to gently fold the dry ingredients into the wet until just a few streaks of flour remain. Fold in the dark chocolate chips and toasted nuts.
  4. Spread the batter evenly into a parchment-lined 8x8 inch metal baking pan. Bake at 350°F (175°C) for 22-25 minutes until edges are golden brown and the center remains slightly soft.
  5. Allow the blondies to cool completely in the pan for at least 1 hour before slicing.
