• 1 cup granulated sugar
• ½ teaspoon vanilla extract

How to Make Blueberry Blondies

1. Melt the butter and white chocolate

Melt the unsalted butter in a saucepan on the stove over medium heat.

While the butter melts, place the white chocolate chips in a measuring cup or bowl.

Once the butter is completely melted, pour it over the white chocolate chips. Let the mixture rest for 5 minutes.

Whisk until the butter and white chocolate are incorporated. Allow the mixture to cool for 30 minutes, or until it starts to thicken back up.

2. Prepare the oven and pan

Preheat the oven to 350°F and place the oven rack in the center.

Line an 8×8-inch baking pan with parchment paper and coat it with non-stick cooking spray.

3. Mix the wet ingredients

Add the cooled butter and white chocolate mixture to a separate bowl along with the granulated sugar.

Whisk for 1 to 2 minutes, until fully incorporated and some of the sugar has absorbed.

Add the vanilla extract, followed by the eggs. Whisk until incorporated.

4. Add the dry ingredients

Add the all-purpose flour and salt.

Using a silicone spatula, fold the mixture a few times until the batter begins to come together.

5. Add the blueberries

Add the fresh blueberries and gently fold them into the batter.

Be careful not to overmix.

Pour the batter into the prepared 8×8-inch baking pan and spread it into an even layer.

6. Bake

Bake for 35 to 45 minutes.

The top and edges should be caramelized and brown. A toothpick inserted into the center should come out with a few crumbs or clean.

7. Cool and slice

Allow the blueberry blondies to cool to room temperature.

Remove them from the pan and cut into 12 or 16 slices before serving.
