Preheat the oven to 350°F (175°C). Line a 9-inch square baking pan with parchment paper, leaving long edges for easy lifting.

Cream the butter and sugar together until fluffy. Beat in the egg until fully incorporated, then mix in the lemon juice. The lemon juice may not fully incorporate, which is normal.
03 -
Whisk together the flour, baking powder, and salt. Gradually add the dry mixture to the wet ingredients, mixing until no dry flour remains.

Gently fold in the diced strawberries. Spread the batter evenly into the prepared pan. The dough will be thick, so take your time.
05 -
Bake for 30-35 minutes, or until the edges begin to turn golden and the center is set. A toothpick inserted into the center should come out moist but not wet. Let the blondies cool completely on a rack.
06 -
Puree trimmed strawberries in a small food processor. Strain the puree through a small strainer to extract 1 tablespoon of puree.
07 -
Whisk together the powdered sugar, strawberry puree, and lemon juice until smooth. Adjust consistency by adding more sugar if too thin or more lemon juice if too thick.

Spread the glaze evenly over the cooled blondies. Allow it to set before slicing into bars.
