Strawberry Lemon Blondies

Strawberry lemon blondies combine juicy strawberries, fresh lemon juice, and chewy blondie batter into the best fruity treat! With just 8 ingredients and one bowl, you will love these easy strawberry blondies for any occasion!

Ingredients

  • 1 cup diced fresh strawberries plus extra slices for the top
  • 2 teaspoons lemon juice
  • ½ cup unsalted butter melted and cooled to room temperature
  • ½ cup + 2 tbsp light brown sugar packed
  • 1 large egg room temperature
  • 1 large egg yolk room temperature
  • 1 teaspoon lemon zest about ¼ lemon zested
  • 1 ¼ cup all-purpose flour *See notes below for meauring*
  • ¼ teaspoon baking powder
  • ½ teaspoon fine sea salt

Instructions

  • Prepare a square 8x8 baking pan with parchment paper on all sides, then preheat the oven to 350F/180C.
  • In a small bowl, combine the diced strawberries and lemon juice and set them aside.
  • In a medium bowl, whisk together the room temperature melted butter, lemon zest, and light brown sugar until combined.
  • Whisk in the egg and egg yolk until combined.
  • Use a rubber spatula to fold in the flour, baking powder, salt, and strawberries until just combined. Then evenly spread the blondie batter into the prepared pan, using a spatula to smooth the top. Press a few thinly sliced strawberries on top.
  • Bake the blondies for 20-30 minutes, or until a toothpick inserted into the middle comes out with just a few moist crumbs.
  • Let the pan cool completely on a wire rack, then cut into 20 bars.

Notes

*Measure your dry ingredients properly. This is my #1 baking tip! Do not ever scoop a measuring cup into your flour as this always leads to using too much flour. Instead, use the spoon-level method. This means fluffing the flour first, then spooning it into your measuring cup/spoon. For the BEST results, use a kitchen scale!*
Dark vs. light baking pans: Baking trays conduct heat differently depending on what color the pan is. If yours is dark or black you should decrease the heat to 325 F/163 C.
Can I use frozen strawberries? I recommend using fresh strawberries, as frozen berries may have extra water and will make the batter too wet.
