Creating Meyer Lemon Meltaways is a straightforward process when you follow these simple steps:

1. Prepare Your Baking Sheet: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, cornstarch, and salt. Set aside.
3. Cream Butter and Sugars: In a large mixing bowl, beat the softened butter, powdered sugar, and granulated sugar until creamy and light.
4. Add Lemon Zest and Juice: Stir in the zest of the Meyer lemons, fresh lemon juice, and vanilla extract until well combined.
5. Combine Mixtures: Gradually add the dry ingredient mixture to the wet mixture and mix until just combined. The dough will be soft and slightly sticky.
6. Chill the Dough: Wrap the dough in plastic wrap and refrigerate for about 30 minutes to firm it up.
7. Form Cookies: Using a small cookie scoop or your hands, form the dough into small balls, about 1 inch in diameter, and place them on the prepared baking sheet.
8. Bake: Bake in the preheated oven for 10-15 minutes or until the edges are set, but the tops are still pale.
9. Cool Cookies: Remove the baking sheet from the oven and allow the cookies to cool for about 5 minutes. Then transfer them to a wire rack to cool completely.
10. Dust with Powdered Sugar: Once the cookies are cool, dust them generously with powdered sugar before serving.

Following these steps carefully will ensure your Meyer Lemon Meltaways come out perfectly every time!
