Beat the butter and sugar together until light and fluffy, then mix in the egg until well combined. Add the lemon juice - don't worry if it looks a bit curdled at this point!

Whisk together the flour, baking powder, and salt, then gently mix into your wet ingredients until just combined. Carefully fold in your diced strawberries.

Puree fresh strawberries and strain to get 1 tablespoon of puree. Mix with sifted powdered sugar and enough lemon juice to make a spreadable glaze. Pour over cooled blondies and let set before cutting.
