Turn your oven on to 350°F (175°C) and line two baking sheets with parchment paper.

Use a mixer on medium speed to whip the softened butter with powdered sugar until it's fluffy and smooth. This usually takes 2-3 minutes.
03 -
Mix in the grated zest and lemon juice until everything blends nicely into a uniform dough.

In another bowl, mix the flour, cornstarch, and a bit of salt. Slowly add the dry mix to your butter-sugar mixture, stirring gently. You’ll end up with a soft dough that holds its shape.

Scoop out a tablespoon of dough, roll it into a ball, and place it on the baking sheet. Leave about 2 inches between each one. You can gently press them down with your hand or the bottom of a glass.

Pop the sheets in the oven for 10-12 minutes until the edges just slightly start to turn golden. Make sure the tops stay pale.

Let the cookies sit on the baking sheet for 5 minutes once baked. Then move them to a cooling rack to let them cool fully.

In a medium bowl, stir together powdered sugar, lemon juice, and zest until smooth. The glaze should flow but still be thick. Adjust with more powdered sugar or lemon juice to get the texture right.

Once completely cool, use a spoon to drizzle glaze on top of the cookies, letting it run over the sides lightly.

Before the glaze hardens, sprinkle some grated lemon zest on top for that extra pop of flavor.
