Overcome by a cookie craving, I baked up something light and summery to suit the season. These cookies are perfect for hot months when chocolate-laden desserts are too heavy. Flavored with lots of lime, these scrumptious cookies are sweet yet sour with a light, crumbly texture. The bite-sized treats are the ideal finish to a picnic or BBQ.
The recipe is simple, but be sure to bake the cookies to a light golden perfection, otherwise, the zesty lime flavor is lost to the buttery shortbread. To learn how to make these shortbread cookies with a refreshing lime twist read more!
Modified from Martha Stewart
Ingredients
12 tablespoons (1 1/2 sticks) unsalted butter, room temperature
1 cup confectioners' sugar
Grated zest of 4 limes
3 tablespoons freshly squeezed lime juice
1 tablespoon pure vanilla extract
1 3/4 cups, plus 2 tablespoons all-purpose flour
2 tablespoons cornstarch
1/4 teaspoon salt
Directions
- In the bowl of an electric mixer fitted with the whisk attachment, cream butter and 1/3 cup sugar until fluffy. Add lime zest, juice, and vanilla; beat until fluffy.

- In a medium bowl, whisk together flour, cornstarch, and salt. Add to butter mixture, and beat on low speed until combined.

- Between two 8-by-12-inch pieces of parchment paper, roll dough into two 1 1/4-inch-diameter logs. Chill at least 1 hour.

- Heat oven to 350 degrees. Line two baking sheets with parchment. Remove parchment from logs; slice dough into 1/8-inch-thick rounds. Place rounds on baking sheets, spaced 1 inch apart.

- Bake cookies until barely golden on the edges, about 8-10 minutes. Transfer cookies to a wire rack to cool slightly, 8 to 10 minutes. Place remaining 2/3 cup sugar in a resealable plastic bag. While still warm, place cookies in the sugar-filled bag; toss to coat. Bake or freeze remaining dough. Store baked cookies in an airtight container for up to 2 weeks.

8Actually ladies it was a total coincidence that Yum and Smitten Kitchen made these cookies on the exact same day! The recipe was recently featured as Martha Stewart's cookie of the day and ended up in my inbox as well. It's such a fabulous recipe and obviously great minds think alike!
9Yummmmmy!! Looks great. I love limes and shortbread. Mmm. That's pretty crazy that both Yum and Smitten Kitchen independently posted the same recipe on the same day. Anyway, I appreciate both bringing me this fab recipe!
