Cream the butter and sugar together until light and fluffy. Beat in the egg until fully incorporated.

Mix in the lemon juice. It may not fully incorporate at this stage, which is fine.

In a separate bowl, 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 fresh strawberries. Transfer the dough to the prepared pan and spread it out evenly. Use a large offset spatula for best results.

Bake for 30-35 minutes, or until the edges are lightly golden and the center is set. A toothpick inserted in the center should come out moist but not wet. Let the blondies cool completely on a rack.

For the glaze, trim and puree the strawberries in a small food processor. Strain through a small strainer to obtain 1 tablespoon of puree.
09 -
Whisk together powdered sugar, strawberry puree, and lemon juice until smooth and lump-free. Adjust thickness by adding more sugar or lemon juice as needed.
