Equipment
- Mixing bowl
- Hand mixer or stand mixer
- Measuring cups and spoons
- Baking sheet
- Parchment paper
- Knife (for slicing dough)
- Plastic wrap (for chilling dough)
- wire cooling rack
Ingredients
- 1 cup unsalted butter softened
- 2/3 cup granulated sugar
- 1 tablespoon lemon zest packed
- 2 teaspoons fresh lemon juice
- 1 teaspoon vanilla extract
- 2 cups all-purpose flour
- 1/4 teaspoon salt
Optional
- 1 tablespoon cornstarch replace 1 tablespoon of flour
- 2 tablespoons coarse sugar for topping
Instructions
- Preheat oven to 325°F (163°C) and line a baking sheet with parchment paper.
- In a mixing bowl, rub the lemon zest into the granulated sugar using your fingers until fragrant.
- Add the softened butter and beat with a mixer for 1–2 minutes until smooth. Do not overmix or whip air into the mixture.
- Mix in the lemon juice and vanilla extract until fully combined.
- Add the flour and salt (and cornstarch if using). Mix until a soft dough forms. The dough should be slightly crumbly but hold together when pressed.
- Shape the dough into a log about 2 inches thick. Wrap and chill in the refrigerator for 30–45 minutes.
- Slice the dough into 1/4-inch thick rounds and place on the prepared baking sheet, spacing slightly apart. Sprinkle with coarse sugar if desired.
- Bake for 15–18 minutes, until the edges are lightly golden and the tops look dry and set.
- For extra crispness, turn off the oven and leave the cookies inside for an additional 5 minutes.
- Allow cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. Cookies will crisp up fully as they cool.
Notes
- For the best crispy lemon shortbread cookies, use granulated sugar instead of powdered sugar. This helps create a firm, crunchy texture rather than a soft, melt-in-your-mouth cookie.
- Do not skip chilling the dough. Chilling for at least 30–45 minutes prevents spreading and keeps the cookies thin and crisp while baking.
- The key to strong lemon flavor without losing crispness is using fresh lemon zest. Avoid adding extra lemon juice, as too much liquid can make the cookies soft instead of crunchy.
- If your dough feels sticky, add 1–2 tablespoons of flour. If it feels too crumbly, gently knead it until it comes together. The dough should hold its shape when pressed.
- Slice the dough thin (about 1/4 inch or slightly thinner) for the crispiest results. Thicker cookies will be more tender and less crunchy.
- Bake until the cookies look dry on top and lightly golden on the edges. Underbaking will result in soft cookies instead of crispy shortbread.
- For extra crisp texture, turn off the oven and let the cookies sit inside for 5–10 additional minutes after baking.
- Cookies will continue to firm up as they cool. Allow them to cool completely on a wire rack to achieve the perfect crisp snap.
- Store in an airtight container at room temperature for up to 1 week. If cookies lose crispness, reheat in a 300°F oven for 3–5 minutes to restore texture.
- This easy lemon shortbread recipe is perfect for making ahead. You can freeze the dough log for up to 2 months and slice and bake when ready.
