  • Wet Ingredients: ½ cup (113 g) unsalted butter, ½ cup (85 g) white chocolate chips, 1 cup (200 g) granulated sugar, 2 large eggs, ½ teaspoon vanilla extract
  • Dry Ingredients: 1 cup (125 g) all-purpose flour, ½ teaspoon salt
  • Add-ins: ½ cup (75 g) fresh blueberries, washed and dried

Instructions

Step 1
Melt the unsalted butter in a saucepan over medium heat. Place the white chocolate chips in a heatproof bowl.
Step 2
Pour the hot melted butter over the white chocolate chips. Let stand for 5 minutes, then whisk until smooth. Allow the mixture to cool for about 30 minutes, until it thickens slightly.
Step 3
Preheat the oven to 350°F (175°C). Line an 8x8-inch (20x20 cm) baking pan with parchment paper and lightly coat with non-stick cooking spray.
Step 4
In a large mixing bowl, combine the cooled butter-chocolate mixture and granulated sugar. Whisk until fully incorporated and slightly lightened in color.
Step 5
Add the vanilla extract and eggs. Whisk again until smooth and combined.
Step 6
Add the flour and salt. Using a silicone spatula, gently fold the mixture just until a batter forms—do not overmix.
Step 7
Gently fold in the blueberries. Pour the batter into the prepared pan and spread into an even layer.
Step 8
Bake for 35–45 minutes, until the top and edges are golden brown and a toothpick inserted in the center comes out with a few moist crumbs or clean.
Step 9
Allow the blondies to cool completely in the pan. Remove from the pan using the parchment, and cut into 12 or 16 bars. Serve at room temperature.

Zusatztipps für die Zubereitung

To ensure your blondies achieve the perfect fudgy consistency, be sure to let the butter and white chocolate mixture cool for the full 30 minutes. This prevents the eggs from scrambling and ensures a smooth, even batter. When folding in the blueberries, use a gentle touch to avoid breaking the skins and staining the entire batter blue.

Varianten und Anpassungen

For an extra layer of flavor, try adding a pinch of fresh lemon zest to the batter. If fresh blueberries are out of season, you can use frozen berries; just be sure to add them straight from the freezer without thawing and expect to extend the baking time by a few minutes.

Serviervorschläge

These bars are delightful on their own at room temperature, but you can elevate them into a decadent dessert by serving them warm with a scoop of premium vanilla ice cream.

What makes these bars fudgy and chewy?

The combination of melted butter and white chocolate creates a rich, moist base, while careful folding of the flour ensures a dense, chewy texture.
