Preheat oven to 350°F and prepare two baking sheets with nonstick silicon mats or parchment paper. Set aside.
In a medium bowl, whisk to combine flour, baking soda, baking powder and salt. Set aside.
In the large bowl of a stand mixer, add butter and sugar and beat on high speed until creamed together.
Add egg, tequila, lime juice, Triple Sec and lime zest and beat until just combined.
With the mixer running on low speed, add flour a little at a time until just combined and no streaks of flour remain.
Using a medium cookie scoop (about 1 ½ to 2 tablespoons), portion out balls of dough onto prepared cookie sheets with no more than 6 to each sheet. Roll them between the palms of your hands to form balls.
Optional before baking, but encouraged:
- Add a little more fresh lime zest to the top- Roll in coarse sparkling sugar- Top with a sprinkle with coarse sparkling sugar- Top with a sprinkle of margarita salt or maldon flake salt- Top with a sprinkle of sugar and salt combined!
Bake for 12 minutes. You want them to be set and crinkled, but not yet golden. Let cool on baking sheet for a couple minutes, then transfer to wire racks to cool completely.
