Introduction

Lemon Shortbread Cookies bring a refreshing twist to a classic buttery treat. Infused with bright lemon zest and a delicate lemon glaze, these cookies are perfect for teatime or any occasion that calls for a light, citrusy indulgence.

A stack of six round cookies with scalloped edges is shown, each cookie having a light golden brown color. The top of each cookie is covered with a smooth white icing layer that appears slightly glossy and thin, with small pieces of yellow zest scattered on top and some dripping slightly on the sides. The cookies are stacked vertically, resting on a white plate with a subtle raised edge. The background is a clean white marbled texture. A few small cookie crumbs and lemon wedges are faintly 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 Tbsp; 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: coarse sparkling sugar, for sprinkling (if not icing cookies)
1 cup (120g) confectioners’ sugar, sifted
1 Tablespoon (15ml) fresh lemon juice (for icing)
1 Tablespoon (15ml) milk, heavy cream, or half-and-half (for icing)
1/4 teaspoon pure vanilla extract (for icing)
Optional: fresh lemon zest for garnish (icing)

Instructions

Step 1: Place the granulated sugar and lemon zest in a small food processor. Pulse about 12–15 times until the sugar is moistened and the zest is finely chopped. This step is important for a fragrant cookie.
Step 2: In a large bowl, use a handheld or stand mixer with a paddle attachment to beat the lemon sugar and softened butter on high speed until creamy, about 3 minutes. Scrape the sides and bottom of the bowl as needed.
Step 3: Add the lemon juice and vanilla extract to the bowl. Beat until combined, scraping down the sides again.
Step 4: Add the all-purpose flour, cornstarch, and salt. Beat on low speed for 1 minute as 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 yet soft.
Step 5: Lightly flour a piece of parchment paper or a silicone baking mat. Roll the dough out with a floured rolling pin to about 1/4 to 1/2 inch thick. Adjust flour as needed if dough is sticky. Transfer the parchment or mat with dough onto a baking sheet, cover, and refrigerate for at least 3 hours or up to 2 days.
Step 6: When ready, preheat your oven to 350°F (177°C). Line baking sheets with parchment paper or silicone mats.
Step 7: Use a cookie cutter to cut the dough into desired shapes. Re-roll scraps and continue cutting. Work quickly — if the dough softens, refrigerate shaped cookies for 15 minutes before baking.
Step 8: Optionally, gently poke holes on the top of the cookies with a fork without piercing all the way through. If you prefer no icing, sprinkle coarse sparkling sugar on top before baking; it will stick as the cookies bake.
Step 9: Bake for 14–15 minutes until edges are set and just starting to turn golden. Smaller cookies may need less time; larger ones may require more. Let cookies cool on the baking sheet for 10 minutes, then transfer to a wire rack to cool completely.
Step 10: For the icing, whisk confectioners’ sugar, lemon juice, milk or cream, and vanilla in a small bowl until smooth. Dip the cooled cookie tops in the icing and let excess drip back into the bowl. Place cookies on a rack or baking sheet to dry. Garnish with fresh lemon zest if desired. Allow icing to set for 1 to 2 hours.
Step 11: Enjoy immediately or wait for icing to fully set. Once dry, store as desired.

Tips & Variations

Using a food processor to blend sugar and lemon zest intensifies the lemon flavor—don’t skip this step.
For a dairy-free version, substitute the butter with a plant-based alternative and use almond or oat milk for the icing.
If you prefer a crunchier cookie, bake a few extra minutes but watch carefully to avoid over-browning.
Try adding finely chopped fresh thyme or rosemary to the dough for an herbal twist that pairs beautifully with lemon.

Storage

Store iced cookies at room temperature in an airtight container for up to 3 days or refrigerate for up to 5 days. Plain cookies without icing will keep at room temperature for up to 5 days. If refrigerated, allow iced cookies to come to room temperature before serving for best flavor. These cookies also freeze well when wrapped tightly; thaw completely before icing.

How to Serve

The image shows many round cookies with scalloped edges scattered on a white marbled surface. Each cookie has two layers: the bottom layer is a pale golden cookie base with a slightly grainy texture, and the top layer is a smooth white icing that covers the entire surface of the cookie. Small yellow lemon zest bits are sprinkled across the icing, adding color contrast. One cookie is plain without icing, topped with a small lemon wedge slice. Another cookie shows a bite taken out of it, revealing the cookie's thickness and texture. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I make these cookies ahead of time?

Yes, you can prepare the dough and refrigerate it for up to 2 days before baking. After baking, iced cookies keep well for several days as described in storage instructions.

What if I don’t have fresh lemons for zest or juice?

Fresh lemon zest and juice are key for the best flavor. If unavailable, use high-quality bottled lemon juice sparingly and consider adding a tiny amount of lemon extract as a backup. Avoid using dried lemon zest as it lacks brightness.
