If you’re looking to take your shortbread to the next level, look no further! These delicate, melt-in-your-mouth lemon cookies are a lighter twist on classic shortbread. Confectioners’ sugar lends them their namesake “whipped” texture, while the addition of masa harina provides a touch of corn flavor that pairs nicely with lemon.
Preheat the oven to 325°F. Lightly grease (or line with parchment) two baking sheets.
Weigh your flours; or measure by gently spooning into a cup, then sweeping off any excess.
In a small bowl, whisk together the masa harina and flour. Set aside.
In a medium bowl, beat together the butter, confectioners’ sugar, salt, and lemon zest at medium-high speed until very smooth and creamy, about 5 minutes. Stop to scrape down the sides of the bowl as needed.
Stir in the vanilla and lemon paste.
Add the dry ingredients, mixing on low speed until the dough comes together.
Portion the dough into 1 1/2" balls; a level tablespoon cookie scoop works well here.
Gently roll the dough balls in granulated sugar to coat before placing onto the prepared baking sheets, leaving about 2” between them.
Use a fork to lightly flatten the top of each cookie once.
Bake the cookies for 12 to 16 minutes, or until they’re set and the edges are starting to brown slightly.
Remove the cookies from the oven and allow them to cool right on the baking sheet; they’re quite fragile when warm. Cool completely before serving.
Store cookies, well wrapped, at room temperature for several days; freeze for longer storage.
Masa harina (translation: dough flour) is flour made from corn that’s been soaked in a solution of slaked lime (nixtamalized) to loosen its hull and soften it, which improves its texture and helps release its nutrients. The soaked corn is ground into a paste (masa), dried, and then ground again, this time into a fine flour. Due to the corn’s special treatment, neither cornmeal nor corn flour are good substitutes for masa harina.
