Equipment

8x8 inch metal pan lined with parchment paper
Skillet
Mixing bowls
Measuring spoons
Scale/measuring cups
Whisk
Spatula

Ingredients

10 tablespoons (140 g) unsalted butter
¾ cup (150 g) light brown sugar packed (dark brown sugar works too)
1 large egg room temperature
1½ teaspoons vanilla extract
1⅓ cups (166.67 g) all-purpose flour weighed in grams or spooned and leveled
½ teaspoon baking powder
½ teaspoon salt
flaky sea salt optional, for topping

Instructions

Preheat oven to 350°F and line an 8-inch square metal pan with parchment paper (hanging over the sides for easy removal).
In a skillet over medium/low heat, cook the butter while stirring constantly until brown bits form on the bottom and it gives off a nutty scent.
Transfer to a heat-proof bowl and let cool to room temperature.
In a medium/large bowl, mix together the cooled brown butter and brown sugar really well. Stir in the egg and vanilla extract.
Mix the flour, baking powder, and salt into the wet ingredients until combined.
Press the blondie batter into the prepared pan and bake on the middle rack until the edges are light tan and center is barely set (about 18-21 minutes). Top with flaky sea salt (optional).
Transfer to a wire rack to cool completely once they're firm enough to lift out of the pan.

Notes

Storage: Store cooled blondies in an airtight container at room temperature for up to 5 days or in the freezer for 2 months.
