In a medium/large bowl whisk the cooled down melted butter, granulated sugar, and powdered sugar together.
Add in the eggs, lemon zest, lemon juice, vanilla extract, and lemon extract, and mix to combine.
Gently fold in the flour and salt until the flour mixture disappears. Pour the batter into the prepared baking pan, spread the lemon blondie batter evenly, and bake for 16-17 minutes. The blondies won't look golden brown.
