GOOEY BROWN BUTTER BLONDIES WITH PECANS

Steps:

• Brown butter mixture:
• Cook butter in a medium saucepan over medium heat, stirring often, until butter foams,
• then browns, 5-8 minutes. Transfer brown butter to a medium bowl; let cool slightly. Add egg, brown sugar, vanilla, and salt and beat until mixture is light and falls back onto itself in a slowly dissolving ribbon, about 3 minutes. Fold in flour.
• Blondie:
• Preheat oven to 350°. Butter a 13x9" baking dish and dust with flour. Toast pecans on a rimmed baking sheet, tossing once, until slightly darkened and fragrant, 8-10 minutes. Let cool.
• Whisk baking powder, salt, and 2 1/4 cups flour in a medium bowl. Using an electric mixer on medium-high speed, beat brown sugar and 1 cup butter in a large bowl until light and fluffy, about 5 minutes. Add eggs one at a time, beating between additions; mix until pale and fluffy, about 2 minutes. Mix in vanilla.
• Reduce speed to low and mix in dry ingredients. Fold in half of pecans. Scrape two-thirds of batter into prepared baking dish; smooth top, pushing batter to edges. Alternating, dollop brown butter mixture and remaining batter on top. Smooth and sprinkle remaining pecans over.
• Bake until blondie is golden brown and firm (a tester will not come out clean), 30-35 minutes. Let cool before slicing. Serve with ice cream.
• Do ahead: Blondies can be made 1 day ahead. Store tightly wrapped at room temperature.
