Blueberry Blondie Bars (Printable Version)

Chewy blondie bars infused with fresh blueberries and white chocolate, perfect for a fruity dessert moment.

# What You'll Need:

→ Wet Ingredients

01 - ½ cup unsalted butter
02 - ½ cup white chocolate chips
03 - 1 cup granulated sugar
04 - 2 large eggs
05 - ½ teaspoon vanilla extract

→ Dry Ingredients

06 - 1 cup all-purpose flour
07 - ½ teaspoon salt

→ Add-ins

08 - ½ cup fresh blueberries, washed and dried

# Steps to Follow:

01 - Melt unsalted butter in a saucepan over medium heat. Place white chocolate chips in a heatproof bowl and pour hot melted butter over them. Let stand for 5 minutes, then whisk until smooth. Allow mixture to cool for about 30 minutes until it thickens slightly.
02 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper and lightly coat with non-stick cooking spray.
03 - In a large mixing bowl, combine cooled butter-chocolate mixture and granulated sugar. Whisk until fully incorporated and slightly lightened in color. Add vanilla extract and eggs, then whisk again until smooth and combined.
04 - Add flour and salt to the wet mixture. Using a silicone spatula, gently fold the mixture just until a batter forms—do not overmix.
05 - Gently fold blueberries into the batter. Pour into prepared pan and spread into an even layer.
06 - 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.
07 - Allow blondies to cool completely in the pan. Remove from pan using parchment paper and cut into 12 or 16 bars. Serve at room temperature.

# Additional Tips::

01 -
  • They strike that impossible balance between fudgy and chewy without any fussy tempering or special equipment.
  • Fresh blueberries burst during baking, creating little flavor pockets that feel like a surprise in every bite.
  • One batch feeds a crowd, and they actually taste better the next day when flavors meld together.
02 -
  • Those blueberries need to be completely dry before folding in, or their moisture will seep into the batter and create an unpleasant soggy spot at the bottom of your pan.
  • The cooling time for the butter-chocolate mixture is non-negotiable—rushing this step by even ten minutes risks cooking your eggs and breaking your batter.
03 -
  • Use parchment paper that hangs over two sides of your pan—it saves you from trying to dig these out with a spatula and destroying their perfect edges.
  • If your white chocolate chips are large, chop them slightly smaller so they melt evenly and distribute more evenly throughout the batter.
