White Chocolate Lemon Blueberry Blondies (Print)

Chewy blondies studded with blueberries, lemon zest and white chocolate—buttery bars perfect for sharing.

# Ingredients:

→ Blondie Base

01 - 1/2 cup unsalted butter, melted and cooled
02 - 3/4 cup packed light brown sugar
03 - 1/4 cup granulated sugar
04 - 1 large egg, room temperature
05 - 1 1/2 tsp pure vanilla extract
06 - Zest of 1 lemon
07 - 2 tbsp fresh lemon juice
08 - 1 1/2 cups all-purpose flour
09 - 1/2 tsp baking powder
10 - 1/4 tsp fine sea salt

→ Mix-ins

11 - 1/2 cup white chocolate chips or chopped white chocolate
12 - 3/4 cup fresh blueberries (plus a few extra for topping)

# Directions:

01 - Preheat oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving an overhang on two sides for easy removal.
02 - In a large bowl, whisk the melted, slightly cooled butter with the packed brown sugar and granulated sugar until the mixture is smooth and homogenous.
03 - Whisk in the egg, vanilla extract, lemon zest and lemon juice until fully incorporated and the batter is glossy.
04 - Sift the all-purpose flour, baking powder and fine sea salt into a separate bowl. Fold the dry ingredients into the wet mixture just until combined; avoid overmixing to maintain chewiness.
05 - Gently fold the white chocolate and fresh blueberries into the batter, taking care not to crush the berries.
06 - Evenly transfer the batter to the prepared pan and smooth the surface. Dot the top with the reserved blueberries and a few extra white chocolate chips if desired.
07 - Bake for 28–32 minutes, or until the center is just set and the edges are lightly golden. The center should still be slightly soft to the touch — it will firm as it cools.
08 - Allow the bars to cool completely in the pan. Use the parchment overhang to lift them out, then slice into 12 even blondies.

# Expert Tips:

01 -
  • This blondie boasts chewy edges and a gooey, tangy center thanks to fresh lemon and pockets of melting white chocolate.
  • It comes together in just one bowl, so cleanup is as breezy as a summer picnic.
02 -
  • If you don’t let them cool before cutting, you’ll end up with a delicious but messy heap instead of neat bars.
  • Adding extra blueberries on top after spreading the batter ensures every bite gets a burst of tangy fruit.
03 -
  • Always grease your baking pan even if you use parchment—it prevents sticky corners.
  • If you’re feeling adventurous, swap in raspberries for a stronger tart note or double the lemon for zing.
