Ingredients
Wet Ingredients
- 1 cup unsalted butter (226 grams), melted and cooled
- 2 large eggs
- 2 teaspoons vanilla bean paste
Sugars
- 1 cup light brown sugar (210 grams)
- 3/4 cup granulated sugar (150 grams)
Dry Ingredients
- 2 cups + 2 tablespoons all-purpose flour (266 grams)
- 1 tablespoon cornstarch
- 1/2 teaspoon salt
Add-ins
- 1 1/2 cups chocolate chips (270 grams) or your preferred mix-ins
Instructions
- Preheat and Prepare Pan: Preheat the oven to 350°F (175°C). Line a 9×13 inch (23×33 cm) baking pan with parchment paper or aluminum foil with overhangs for easy removal, or alternatively lightly grease the pan.
- Mix Butter and Sugars: In a large bowl, whisk together the melted and cooled butter with the light brown sugar and granulated sugar until the mixture is smooth and combined.
- Add Eggs and Vanilla: Whisk in the eggs and vanilla bean paste carefully so that the butter does not separate or melt out of the batter.
- Incorporate Dry Ingredients: Stir in the all-purpose flour, cornstarch, and salt until the batter is smooth and free of flour clumps.
- Fold in Chocolate Chips: Gently fold in the chocolate chips or any mix-ins you prefer to distribute them evenly without overmixing.
- Transfer to Pan: Spoon the blondie batter into the prepared pan and smooth the top with a spatula to create an even layer.
- Bake: Bake in the preheated oven for 24-28 minutes or until the top is set and shiny, and a toothpick inserted in the center comes out clean or with a few moist crumbs.
- Cool and Slice: When done, lift the blondies out of the pan using the parchment or foil overhang and place on a cutting board. Peel back the lining and slice into bars with a sharp knife. If the pan was greased, slice directly in the pan. For clean slices, let the blondies cool completely for about 2 hours.
Notes
- Make sure the melted butter is cooled before mixing with eggs to prevent curdling.
- Cornstarch helps create a tender, soft texture in the blondies.
- You can substitute chocolate chips with nuts, dried fruits, or other mix-ins as preferred.
- Allow blondies to cool fully before slicing to achieve clean edges; if sliced warm, they may be gooey or crumbly.
- Store blondies in an airtight container at room temperature for up to 4 days or freeze for longer storage.
