Introduction

Blueberry blondies offer a delightful twist on traditional blondies, combining sweet white chocolate and fresh blueberries for a fruity, buttery treat. These bars are perfect for dessert or a special snack, bringing a fresh burst of flavor in every bite.

Three square pieces of blueberry blondies are stacked on a white plate, each piece showing a golden brown, slightly crispy top layer with a soft, moist middle layer dotted with deep purple blueberries, and a light yellow crumbly bottom layer. The blueberries are spread within the blondies, creating dark purple spots contrasting against the pale yellow batter. The plate is on a white marbled background, with a silver fork with intricate designs lying beside the stack, and a few white chocolate chips scattered near the plate. In the blurred background, more blueberry blondies sit on a white plate. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

½ cup unsalted butter
½ cup white chocolate chips
1 cup granulated sugar
½ teaspoon vanilla extract
2 eggs
1 cup all-purpose flour
½ teaspoon salt
½ cup blueberries, fresh, washed and dried

Instructions

Step 1: Melt the unsalted butter in a saucepan over medium heat. While it melts, place the white chocolate chips in a separate measuring cup or bowl.
Step 2: Once the butter is fully melted, pour it over the white chocolate chips and let the mixture rest for 5 minutes. Whisk until smooth and then allow it to cool for about 30 minutes, or until it starts to thicken.
Step 3: Preheat your oven to 350 °F and position the rack in the center. Line an 8×8 inch baking pan with parchment paper and spray with non-stick cooking spray.
Step 4: In a separate bowl, combine the butter and white chocolate mixture with the granulated sugar. Whisk for a minute or two until fully incorporated and some sugar has dissolved.
Step 5: Add the vanilla extract, then whisk in the eggs until the batter is smooth and combined.
Step 6: Add the flour and salt, and fold them into the batter gently using a silicone spatula until it just comes together.
Step 7: Carefully fold in the fresh blueberries, taking care not to overmix to avoid breaking the berries.
Step 8: Pour the batter into the prepared baking pan and spread it evenly.
Step 9: Bake for 35 to 45 minutes, until the edges and top are golden brown and caramelized. Check doneness by inserting a toothpick into the center; it should come out with just a few moist crumbs.
Step 10: Let the blondies cool to room temperature in the pan. Then remove and cut into 12 or 16 slices before serving.

Tips & Variations

Use fresh, firm blueberries to prevent bleeding into the batter and keep the blondies visually appealing.
For an extra burst of flavor, add a teaspoon of lemon zest to the batter.
Swap white chocolate chips with dark or milk chocolate chips for a different flavor profile.
Gently fold ingredients to avoid breaking the blueberries and keep the batter light and fluffy.

Storage

Store blueberry blondies in an airtight container at room temperature for up to 5 days. For longer storage, keep them refrigerated for up to 10 days or freeze wrapped tightly in plastic wrap inside an airtight container for up to 3 months. To reheat, warm gently in the microwave or oven to enjoy a soft, fresh taste.

FAQs

Can I use frozen blueberries instead of fresh?

Using frozen blueberries is possible but they may release extra moisture and make the batter more watery, which can affect texture. If using frozen, toss them lightly in flour before folding in and consider reducing other liquids slightly.

How can I tell when the blondies are done baking?

The blondies are ready when the edges and top are golden brown and caramelized. Insert a toothpick in the center—it should come out with just a few moist crumbs, not raw batter.
