# What You’ll Need:

→ Dry Ingredients

01 - 1 1/2 cups all-purpose flour
02 - 1/2 teaspoon baking powder
03 - 1/2 teaspoon salt

→ Wet Ingredients

04 - 1/2 cup unsalted butter, melted and cooled
05 - 1 cup light brown sugar, packed
06 - 1 large egg
07 - 2 teaspoons vanilla extract

→ Add-Ins

08 - 1 cup fresh or frozen blueberries
09 - 1/2 cup white chocolate chips

# How-To Steps:

01 - Preheat the oven to 350°F. Line an 8x8-inch baking pan with parchment paper and lightly grease with butter or cooking spray.
02 - In a medium bowl, whisk together flour, baking powder, and salt until evenly distributed.
03 - In a large bowl, stir melted butter and brown sugar until smooth and no lumps remain. Whisk in the egg and vanilla extract until fully incorporated.
04 - Gradually add the dry ingredients to the wet ingredients, mixing with a spatula until just combined. Do not overmix.
05 - Gently fold in the blueberries and white chocolate chips if using, taking care not to crush the berries.
06 - Spread the batter evenly in the prepared pan, using an offset spatula or the back of a spoon to smooth the top.
07 - Bake for 28-32 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with a few moist crumbs.
08 - Cool completely in the pan before lifting out using the parchment paper overhang and cutting into 12 bars.

# Expert Advice:

01 -
  • The blueberries burst while baking creating little pockets of jammy sweetness throughout
  • These blondies stay incredibly moist for days unlike traditional brownies that can dry out
02 -
  • Overmixing the batter will make your blondies tough and develop too much gluten
  • Frozen blueberries will bleed purple into your batter more than fresh ones, but the flavor is just as good
03 -
  • Use light colored aluminum pans for even bining, dark pans can make the edges too crisp before the center is done
  • Room temperature ingredients prevent the melted butter from seizing and creating lumps
