How to Make White Chocolate Blondies
Step One: Prep the Pan and Oven
Preheat the oven to 350°F. Lightly grease an 8-inch-by-8-inch square baking pan and set aside.
Step Two: Mix the Dry Ingredients
In a medium bowl, stir together the flour, baking powder, baking soda, and salt until evenly combined. Set aside.
Step Three: Cream the Butter and Sugar
In a large bowl, beat the softened butter with an electric mixer on medium speed until smooth. Add the brown sugar and beat for about 2 minutes, until light and fluffy. Beat in the egg and egg yolk until fully incorporated. Add the vanilla extract and mix until blended.
Step Four: Finish the Batter
Add the flour mixture to the butter mixture and beat on medium speed just until blended. Using a spoon or spatula, gently stir in the white chocolate chips.
Step Five: Bake the Blondies
Spread the batter evenly into the prepared pan. Bake for 25 to 30 minutes, or until the edges are light golden brown and the center is set. Cool completely before cutting into bars.
