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

Make sure to allow the butter and white chocolate mixture to cool for the full 30 minutes; this prevents the eggs from cooking prematurely and helps achieve the right batter consistency. When adding the flour, fold it in gently with a silicone spatula just until no dry streaks remain to maintain a chewy texture.

Varianten und Anpassungen

For extra citrus notes, add a pinch of lemon zest to the batter. If fresh blueberries are unavailable, you can substitute them with frozen berries; do not thaw them before adding to the batter, but note that you may need to extend the baking time slightly.

Serviervorschläge

These blueberry blondies are best served at room temperature to appreciate their fudgy texture. For a more indulgent dessert, serve each bar with a generous scoop of vanilla ice cream.
