Strawberry Lemon Blondies are soft, chewy dessert bars bursting with fresh strawberries and bright lemon flavor. They’re sweet, tangy, and topped with a simple lemon-strawberry glaze—like a bite of strawberry lemonade in bar form.
Line an 8×8-inch baking pan with parchment paper and lightly grease it. This makes cleanup easier and keeps the blondies from sticking.
Cream the butter and sugar
In a large bowl, beat the softened butter and sugar until it’s light and fluffy. This helps make the texture soft and tender.
Add egg, lemon juice, and zest
Beat in the egg, lemon juice, and lemon zest until well combined.
Mix in dry ingredients
Add the flour and baking soda. Stir until just combined—don’t overmix or the bars can turn out dense.
Fold in strawberries
Gently fold in the diced strawberries. The dough will be thick, and that’s okay!
Spread and bake
Spread the batter into the prepared pan and smooth the top. Bake at 350°F for 28–32 minutes or until the edges are lightly golden and a toothpick comes out clean or with a few crumbs.
Cool completely
Let the blondies cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before glazing.
Make the glaze
Whisk together powdered sugar, lemon juice, and strawberry jam until smooth. If it’s too thick, add a few drops of lemon juice. If it’s too thin, add more powdered sugar.
Glaze and slice
Pour the glaze over cooled blondies, let it set for about 15 minutes, then slice into squares.
