Ingredients

Scale

Wet Ingredients

  • 6 tablespoons unsalted butter (or salted butter, omit added salt)
  • 4 ounces white chocolate chips
  • 1 cup granulated sugar
  • 1 teaspoon vanilla extract
  • 2 large eggs

Dry Ingredients

  • 1 cup all-purpose flour
  • 1/4 teaspoon salt (omit if using salted butter)

Add-ins

  • 1 cup fresh blueberries, washed and dried

Instructions

  1. Melting the Butter and White Chocolate Base: In a small saucepan, melt the unsalted butter over low heat. Remove from heat and immediately add the white chocolate chips to the warm butter, stirring continuously until the white chocolate has fully melted and the mixture is smooth. Let this butter and chocolate mixture cool completely for about 10 minutes to prevent melting the sugar in the next step.
  2. Mixing up the Blondie Batter: In a large mixing bowl, whisk the cooled butter and white chocolate mixture together with the granulated sugar until well combined. Add the vanilla extract, eggs, and salt (if using) and whisk again until smooth. Carefully fold in the all-purpose flour until just combined—avoid overmixing to keep the blondies tender. Gently fold in the fresh blueberries, coating them evenly in the batter to prevent sinking during baking.
  3. Final Steps: Baking and Serving: Preheat your oven to 350°F (175°C). Line or grease an 8×8 inch baking pan. Pour the batter into the prepared pan and spread it into an even layer. Bake for 30-35 minutes or until the top is golden brown and a toothpick inserted into the center comes out clean or with just a few moist crumbs. Allow the blondies to cool completely in the pan before cutting them into 12 to 16 equal squares. Serve and enjoy!

Notes

  • Always cool the butter and white chocolate mixture before mixing it with sugar to prevent melting the sugar, which can cause dense and wet blondies.
  • Do not add extra blueberries or white chocolate chips beyond the specified amount to avoid a dense or oily texture.
  • Avoid adding toppings on top of the batter before baking as they tend to sink.
  • Use the spoon and level method to measure flour to ensure accuracy and prevent dry, heavy blondies.
