My wife and I have been making lime meltaway cookies for 20 years. They are a small, satisfying cookie that will offer a sweet ending to your holiday meal.
Cream butter and ⅓ cup of the powdered sugar with a hand mixer or a stand mixer fitted with a paddle attachment.
Add lime juice, lime zest, and vanilla. Mix until combined.
In an appropriately sized bowl, sift or whisk together flour, corn starch, and salt.
Add flour mixture to butter mixture and mix on slow speed until combined.
Roll dough to 1/4 inch between 2 pieces of parchment paper and chill for 15 minutes.
When dough is chilled, cut dough into 1 1/2 to 2 inch rounds.
Place rounds on a parchment lined baking sheet one inch apart.
Bake at 350 degrees F for 8-10 minutes or until just lightly golden brown at the edges
After baking, let cookies cool for 15 minutes on a wire rack.
The rest of the powdered sugar can be sprinkled on. The other option is to place the powdered sugar in a plastic bag and add the cookies. Shake carefully not to break the cookies.
