Brown butter blondies are loaded with chocolate chips, pecans, and a sprinkle of coarse salt. The batter bakes in a 9 × 13 pan and yields two dozen bars with crisp edges and fudgy centers, perfect for potlucks, bake sales, or a midnight snack.

Ingredients

  • 1 cup Butter
  • 1 cup Brown Sugar
  • ½ cup Granulated Sugar
  • 2 Eggs
  • 1 ½ teaspoons Vanilla Extract
  • ½ tablespoon Milk
  • 2 ½ cups All-Purpose Flour
  • ½ teaspoon Salt
  • 1 teaspoon Baking Soda
  • 1 cup Semisweet Chocolate Chips
  • 1 cup Chopped Pecans
  • 1 teaspoon Course Salt for topping

Instructions

  • Preheat the oven to 350°F and line a 9x13 baking pan with parchment paper.
  • In a medium saucepan, melt the butter over medium heat. Continue cooking, stirring frequently, until the butter foams and turns golden brown with a nutty aroma (about 5–7 minutes). Remove from heat and let it cool for about 10 minutes.
    1 cup Butter
  • In a large mixing bowl, beat the browned butter with brown sugar and granulated sugar until well combined. Add the eggs, vanilla, and milk, and mix until smooth.
    1 cup Brown Sugar, ½ cup Granulated Sugar, 2 Eggs, 1 ½ teaspoons Vanilla Extract, ½ tablespoon Milk
  • In a separate bowl, whisk together the flour, salt, and baking soda. Gradually stir the dry mixture into the wet ingredients until a thick batter forms.
    2 ½ cups All-Purpose Flour, ½ teaspoon Salt, 1 teaspoon Baking Soda
  • Gently fold in the semisweet chocolate chips and chopped pecans.
    1 cup Semisweet Chocolate Chips, 1 cup Chopped Pecans
  • Spread the batter evenly into the prepared pan. Sprinkle coarse salt evenly over the top.
    1 teaspoon Course Salt
  • Bake for 18–22 minutes, or until the edges are golden and a toothpick inserted in the center comes out clean or with a few moist crumbs.
  • Let the blondies cool completely in the pan before slicing into squares.

Notes

For the Brown Butter:
  • Cook until the milk solids turn deep golden and smell nutty.
  • Cool for about 10 minutes before adding to the bowl so you do not scramble the eggs.
  • Scrape every browned bit into the batter. That is pure flavor!
The Pan:
  • A metal 9 x 13 pan bakes faster and more evenly than glass. If using glass, add 3 to 5 minutes.
  • Line with a parchment sling for easy lifting and clean cuts.
Baking:
  • Start checking at 18 minutes. You want set edges and a slightly soft center.
  • A toothpick should come out with a few moist crumbs, not wet batter.
Storage
  • After the blondies cool, store them in an airtight container. They should be good for about 4 days on the counter.
  • To freeze, wrap the blondies in plastic wrap and then put them in an airtight container for up to 3 months.
