Introduction

Lemon Shortbread Cookies are a delightful twist on a classic treat, combining the rich, buttery texture of shortbread with a fresh, zesty lemon flavor. Perfect for teatime or any time you crave a simple, elegant cookie with a citrusy kick.

A stack of six round cookies with scalloped edges is shown close up on a white plate with a white marbled texture underneath. Each cookie has a light golden brown base with a smooth, pale cream icing layer on top. Small bits of yellow zest are scattered on the icing, adding spots of bright color. The cookies are neatly stacked, showing the even thickness and slightly crumbly texture of the edges. A few crumbs and small lemon wedge pieces are also visible near the base of the stack. photo taken with an iphone --ar 4:5 --v 7

Ingredients

2/3 cup (135g) granulated sugar
2 tablespoons fresh lemon zest

1 cup (16 tablespoons; 226g) unsalted butter, softened to room temperature
1 tablespoon (15ml) fresh lemon juice

1/2 teaspoon pure vanilla extract
2 cups (250g) all-purpose flour (spooned & leveled)

1/3 cup (40g) cornstarch
1/8 teaspoon salt
Optional (if not icing cookies): coarse sparkling sugar, for sprinkling

1 cup (120g) confectioners’ sugar, sifted
1 tablespoon (15ml) fresh lemon juice
1 tablespoon (15ml) milk (any kind), heavy cream, or half-and-half

1/4 teaspoon pure vanilla extract
Optional: fresh lemon zest for garnish

Instructions

Step 1: Place the granulated sugar and fresh lemon zest in a small food processor. Pulse about 12–15 times until the sugar is moistened and the lemon zest is finely chopped. This step is essential for even lemon flavor distribution.

Step 2: In a large bowl, beat the lemon sugar and softened butter together on high speed using a handheld or stand mixer with a paddle attachment. Continue until creamy, about 3 minutes, scraping down the bowl as needed.
Step 3: Add the fresh lemon juice and vanilla extract to the butter mixture. Beat until combined, scraping down the bowl again if necessary.
Step 4: On low speed, add the all-purpose flour, cornstarch, and salt. Beat for 1 minute until the mixture starts to combine, then increase to medium speed and beat until the dough clumps together, about 1–3 minutes. The dough should be thick but soft.

Step 5: Dust a piece of parchment paper or a silicone baking mat generously with flour. Roll the dough out with a floured rolling pin to about 1/4 to 1/2 inch thickness. Use more flour if the dough is sticky. Transfer the rolled dough (on the parchment or mat) to a baking sheet. Cover and refrigerate for at least 3 hours or up to 2 days.
Step 6: Preheat the oven to 350°F (177°C). Line baking sheets with parchment paper or silicone mats.
Step 7: Cut shapes from the chilled dough using a cookie cutter. Re-roll the scraps to use all the dough. If the dough softens during this process, refrigerate the shaped cookies for 15 minutes before baking.

Step 8: Optionally, gently poke holes on the tops of the cookies with a fork without pushing through. If not icing, sprinkle coarse sparkling sugar on top; it will adhere as cookies bake.
Step 9: Bake cookies for 14–15 minutes, until edges are set and just turning golden. Smaller cookies may bake quicker, so watch closely after 10 minutes. Cool cookies on the baking sheet for 10 minutes, then transfer to a wire rack to cool completely.
Step 10: For the icing, whisk together confectioners’ sugar, lemon juice, milk or cream, and vanilla extract in a small bowl until smooth. Dip the tops of cooled cookies into the icing, letting any excess drip off. Place cookies on a rack or baking sheet to dry. Garnish with fresh lemon zest while icing is wet if desired.

Step 11: Let the icing set for 1 to 2 hours before storing or stacking cookies. Enjoy immediately or wait for the icing to firm up.

Tips & Variations

Be sure to pulse the sugar and lemon zest thoroughly to release the oils and maximize flavor.
If you prefer a less tangy cookie, reduce the lemon juice slightly in the dough and icing.

Use a variety of cookie cutters to create festive shapes for holidays or special occasions.
Coarse sparkling sugar adds a pretty crunch if you skip the icing.
For a dairy-free version, use a plant-based butter and milk alternative in the icing.

Storage

Store iced cookies at room temperature, covered, for up to 3 days, or refrigerate for up to 5 days. Plain (un-iced) cookies keep well at room temperature for up to 5 days. To re-soften refrigerated iced cookies, allow them to come to room temperature before serving.

How to Serve

The cookies are layered gently over a white marbled surface, with one cookie showing a bitten edge and another topped with a small lemon wedge. The shortbread base is light golden brown with a slightly crumbly texture, and the white icing on some cookies is glossy and thin, evenly covering the top layer. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I make the dough ahead of time?

Yes, you can refrigerate the dough for up to 2 days before rolling and cutting. This helps the flavors meld and makes the dough easier to work with.

Can I freeze these cookies?

Absolutely. Freeze unbaked, shaped cookies in a single layer on a baking sheet, then transfer them to a freezer-safe bag for up to 3 months. Bake from frozen, adding a couple of minutes to the baking time.
