Best Blondie Recipe

This Best Blondie Recipe yields a rich, buttery bar with a golden crust and a moist, chewy interior. The batter combines melted unsalted butter, both brown and white sugars, eggs, vanilla, and a balanced mix of flour, cornstarch, baking powder, and salt for structure. White chocolate chips and chopped walnuts folded in add sweet pockets and crunchy texture. Baking in a parchment-lined pan ensures easy removal and even cooking. It's a classic dessert that pairs well with coffee or milk and suits sharing at gatherings.

Description

The Best Blondie Recipe brings together melted butter and sugars to create a tender, moist base. Eggs and vanilla extract enrich the batter, while the careful blend of all-purpose flour, cornstarch, baking powder, and salt provides just enough lift and structure. Folding in white chocolate chips and chopped walnuts adds contrasting textures and bursts of sweetness. The result is a dense yet tender blondie with a slightly crisp exterior. Baking in a parchment-lined 13x9 pan at 350°F for 25-30 minutes ensures even cooking without overbaking.

This dessert is well-suited for casual sharing and pairs nicely with beverages like coffee or milk. Cutting into squares after cooling allows clean, tidy servings. The use of both brown and white sugar balances moisture and flavor depth, while the addition of nuts lends crunch.

Using parchment paper for lining the pan helps easy removal and cleanup, though greasing and flouring the pan can substitute if needed. When using a glass pan, baking time may need to be extended for thorough cooking. Mixing half dark and half light brown sugar will yield a richer taste, but all light or all dark sugar can be used depending on preference.

Ingredients

Servings
  • 1 cup butter melted, unsalted
  • 1 ¼ cup brown sugar tightly packed
  • ½ cup sugar
  • 2 egg room temperature preferred, large, plus 1 egg yolk
  • 2 teaspoons vanilla extract
  • 2 ¼ cups all-purpose flour (note that in the video I accidentally said 2 ½ cups flour, that is incorrect, you only need 2 ¼ cups as written here)
  • 2 teaspoons cornstarch
  • ½ teaspoon baking powder
  • 1 teaspoon salt
  • cup white chocolate chips
  • 1 cup walnuts chopped

Instructions

  1. Preheat oven to 350F (175C) and line a 13x9 pan with parchment paper**
  2. Combine melted butter and sugar in a large bowl and stir well.
  3. Add eggs, egg yolk, and vanilla extract and stir until completely combined. Set aside.
  4. In a separate bowl, whisk together flour, cornstarch, baking powder, and salt.
  5. Gradually stir dry ingredients into wet until completely combined.
  6. Fold in white chocolate chips and nuts, if using.
  7. Spread blondie batter into prepared pan and transfer to oven.
  8. Bake on 350F (175C) for 25-30 minutes*** or until a toothpick inserted in the center comes out clean or with a few fudgy crumbs.
  9. Allow to cool before cutting and enjoying

Notes

  • Mixing half dark and half light brown sugar gives a richer, moister blondie, but all dark or all light sugar also works.
  • If parchment paper is unavailable, lightly grease and flour the baking pan to prevent sticking.
  • Glass baking pans may require longer baking times than metal pans for even doneness.
