Step 1
Beat the
Unsalted Butter (225 g)
on high speed with a handheld or stand mixer until creamy, about 1 minute.
Step 2
Switch mixer to medium speed and add the
Granulated Sugar (135 g)
,
Vanilla Extract (5 mL)
and
Almond Extract (2 mL)
, scraping down the sides and the bottom of the bowl as needed.
Step 3
Turn the mixer off and add 1 cup of the
All-Purpose Flour (250 g)
(plus 2 Tbsp), then turn the mixer on low and slowly beat just until combined. Add the remaining 1 cup of flour and again mix slowly just until a very soft dough is formed.
Step 4
Press the dough down into bowl, tightly cover with plastic wrap to chill overnight.
Step 5
The next day, remove the cookie dough from the refrigerator an hour before you intend to start baking.
Step 6
Preheat oven to 350 degrees F (175 degrees C). Line baking sheets with parchment paper (parchment paper seems to work better than silicone mats for these shortbread cookies).
Step 7
Roll the cookie dough into 1-inch balls, making sure they're nice and smooth. Make an indentation with your thumb into each ball. The dough may crack slightly when you press your thumb into it, but you can pinch the dough back together gently.
Step 8
Fill each impression with a scant 1/2 teaspoon of
Key Lime Curd (125 g)
. Place prepared cookies in the refrigerator for 30 minutes or freeze for 10 minutes – this step is MANDATORY!
Step 9
Bake the shortbread thumbprint cookies for 12 to 14 minutes, or until very lightly browned on the edges. The cookies will puff up and spread slightly. Do not overbake!
Step 10
Remove from oven and immediately spoon an additional 1/2 teaspoon of
Key Lime Curd (125 g)
into each cookie, smoothing it around to fill the indentation evenly. Allow the cookies to cool on the baking sheet. Cool to room temperature before glazing.
Step 11
To make the glaze, whisk together the
Powdered Confectioners Sugar (110 g)
, juice from
Limes (1 1/2)
,
Vanilla Extract (5 mL)
and
Light Corn Syrup (5 mL)
until smooth. Add more lime juice to thin out or add more powdered sugar to thicken to your desired consistency.
Step 12
Carefully drizzle over cooled cookies and allow the glaze to set (you can refrigerate to speed this process up). You can sprinkle drizzled glaze with Lime Zest for a pop of color and flavor!
Step 13
Store cookies covered at room temperature for 3 days or in the refrigerator for 5 days.  Baked cookies can be frozen up to 30 days – thaw overnight in the refrigerator.
