Equipment

  • 8-inch square baking pan

Ingredients

  • 4 ounces (1 stick) unsalted butter melted
  • 1 cup brown sugar
  • zest of 1 lemon
  • 1 egg
  • 1 teaspoon vanilla
  • 1 ¼ cups all purpose flour
  • 1 teaspoon baking soda
  • ¾ teaspoon salt
  • 1 cup blueberries fresh or frozen

Instructions

  • Butter an 8x8-inch baking pan. Preheat the oven to 350° F.
  • Melt butter over medium heat. Allow to cool for a few minutes.
  • Whisk melted butter with brown sugar and lemon zest, stirring vigorously until thick and shiny and butter no longer separates, 2-3 minutes.
  • Add egg and vanilla, whisk thoroughly until fully combined.
  • Whisk together flour, baking soda, and salt. Fold into butter mixture using a silicone spatula until a few streaks of flour remain.
  • Add blueberries and fold in gently.
  • Spread batter into prepared pan and smooth top. Bake until golden on top and blondies are mostly set in the middle, 25-30 minutes.
  • Remove from oven and cool on a cooling rack for at least 30 minutes before slicing.
