Use a big bowl to beat the soft butter and confectioner's sugar until it's fluffy. Stir in the grated lemon, lemon juice, and vanilla till everything's combined. In another bow, mix salt, plain flour, and cornstarch together. Slowly add this to the buttery mixture and mix until it turns into pliable dough.

Set your oven to 350°F (175°C) and lay out parchment paper on the trays. Take the chilled dough, remove the wrap, and cut it into thin slices about 1/4 inch thick. Arrange the slices 1 inch apart on the trays. Bake them for 10-12 minutes until the edges start going golden. Let them cool off a bit on the tray.

While they’re warm, softly toss them in the powdered sugar. Want extra lemony oomph? Mix some lemon zest into the sugar beforehand. Move them to a cooling rack till completely cooled. You can coat them again to pile on more powdered sugar if you wanna go extra sweet.
