Preheat #oven{} to 165°C.

If @unsalted butter{227%g} is not very soft, melt two tablespoons of it. Place the remainder in a #large bowl{}. Pour the melted butter in and stir with a #wooden spoon{} until the butter is the texture of mayonnaise.

Add @kosher salt{5%g} and stir to combine. Add @granulated sugar{134%g} and @vanilla extract{1.5%tsp} (optional) and stir again. Finally, add @all-purpose flour{256%g} and stir just until the flour is absorbed — the dough will still be lumpy.

Press dough into an ungreased or parchment-lined #20-23cm square baking pan{}. Bake until golden brown, ~{35%minutes} to ~{40%minutes} for a 23cm pan, or ~{45%minutes} to ~{50%minutes} for a 20cm pan.

Transfer to a #wire rack{} to cool. Cut into squares, bars, or wedges while still warm. Sprinkle with @sparkling sugar{} if desired.
