  • Total Time: 40 minutes
  • Yield: 15 servings

Ingredients

Wet Ingredients

  • 1 cup unsalted butter (melted)
  • 1 ¼ cup brown sugar (firmly packed)
  • ½ cup granulated sugar
  • 2 large eggs + 1 egg yolk (room temperature preferred)
  • 2 teaspoons vanilla bean paste

Dry Ingredients

  • 2 ¼ cups all-purpose flour
  • 2 teaspoons cornstarch
  • ½ teaspoon baking powder
  • 1 teaspoon salt

Add-ins

  • ⅔ cup white chocolate chips
  • 1 cup chopped walnuts (optional)

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) and prepare a 13×9 inch metal baking pan by lining it with parchment paper or lightly greasing and flouring the pan to prevent sticking.
  2. Mix Wet Ingredients: In a large bowl, combine the melted butter with both the brown and granulated sugars. Stir thoroughly to mix the sugars into the butter.
  3. Add Eggs and Vanilla: Add the two whole eggs, the extra egg yolk, and the vanilla bean paste to the butter and sugar mixture. Stir until the mixture is fully combined and smooth. Set this mixture aside.
  4. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, cornstarch, baking powder, and salt to ensure even distribution of the leavening agents and salt.
  5. Incorporate Dry into Wet: Gradually add the dry ingredients to the wet ingredients, stirring gently until just combined. Avoid overmixing to maintain a tender texture.
  6. Fold in Add-ins: Carefully fold in the white chocolate chips and chopped walnuts (if using), distributing them evenly throughout the batter.
  7. Prepare for Baking: Spread the blondie batter evenly into the prepared baking pan, smoothing the surface with a spatula for uniform thickness.
  8. Bake: Place the pan in the preheated oven and bake for 25 to 30 minutes. Test doneness by inserting a toothpick into the center; it should come out clean or with a few moist crumbs, indicating fudgy blondies.
  9. Cool and Serve: Allow the blondies to cool completely in the pan before cutting into squares to ensure clean slices and enhanced flavor.

Notes

  • Firmly pack the brown sugar to avoid air pockets and ensure accurate sweetness and moisture.
  • Walnuts are optional and can be omitted or substituted with other nuts or mix-ins like pecans or chocolate chunks.
  • Room temperature eggs help the batter blend more smoothly.
  • Use parchment paper for easy removal and cleaner slicing.
  • Do not overbake to keep the blondies moist and fudgy rather than dry and cakey.
