In a large bowl using a hand mixer or in the bowl of a stand mixer, beat the softened butter and 1/2 cup of powdered sugar on medium speed until light and fluffy, about 3-4 minutes. Scrape down the sides of the bowl as needed.

Add the 2 tablespoons of Meyer lemon zest and the vanilla extract to the butter mixture. Mix on low speed until just combined.

In a separate medium bowl, whisk together the all-purpose flour and cornstarch. With the mixer on its lowest speed, gradually add the dry ingredients to the wet ingredients, mixing until just combined and a soft dough forms.

Shape the dough into a flat disc, wrap it tightly in plastic wrap, and refrigerate for at least 1 hour, or until firm.

Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper. Scoop tablespoon-sized portions of the chilled dough and roll them into 1-inch balls. Place them about 1 inch apart on the prepared baking sheet. Bake for 12-15 minutes, or until the bottoms are lightly golden. The tops will remain pale.

While the cookies are baking, prepare the coating. In a small, shallow bowl, whisk together the 1 cup of powdered sugar and 1 tablespoon of Meyer lemon zest. Let the cookies cool on the baking sheet for just 2-3 minutes, then, while still warm, gently roll each cookie in the lemon sugar mixture until fully coated. Transfer to a wire rack to cool completely.
