Lemon Zucchini Cookies Recipe delivers bright lemon zest, soft cake-like centers, crisp edges, and a tangy glaze. You will love it if you crave soft lemon cookies with a fresh twist, and you can bake a batch in about 1 hour total.

Ingredients You’ll Need
- 1 cup finely grated zucchini, well squeezed dry, about 1 medium zucchini, 150 g after squeezing; thawed frozen shredded zucchini works too
- 1/2 cup unsalted butter, softened, 113 g; high-fat European butter adds extra richness
- 3/4 cup granulated sugar, 150 g
- 1/4 cup light brown sugar, packed, 50 g, optional for extra chew
- 1 large egg, room temperature
- 1 tablespoon finely grated lemon zest, from about 2 lemons
- 2 tablespoons fresh lemon juice; pantry shortcut: 1 tablespoon bottled 100 percent lemon juice plus 1/2 teaspoon lemon extract
- 1 teaspoon vanilla extract, use pure for best flavor
- 2 cups all-purpose flour, 240 g; I like King Arthur or Gold Medal for consistent results
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon fine sea salt
- 1 tablespoon cornstarch, optional for ultra-soft centers
- Optional mix-ins: 1/2 cup white chocolate chips or chopped toasted almonds, or 1 teaspoon poppy seeds
Lemon glaze
- 1 cup powdered sugar, 120 g
- 2 to 3 tablespoons lemon juice
- 1 teaspoon lemon zest
- 1 teaspoon milk or water to adjust texture, as needed
- Pinch fine sea salt
Equipment
- Box grater and clean kitchen towel
- Microplane zester
- Mixing bowls, hand mixer or stand mixer
- Rubber spatula
- 1.5 tablespoon cookie scoop or tablespoon measure
- Rimmed baking sheets lined with parchment or silicone mats
- Wire rack and an oven thermometer for accuracy
How to Make Lemon Zucchini Cookies
- Prep: 20 minutes
- Cook: 10 to 12 minutes per batch
- Total: about 1 hour including cooling and glazing
- Heat the oven to 350°F. Line two baking sheets with parchment. Pull the butter and egg to room temperature if you have not already.
- Grate the zucchini on the small holes of a box grater. Wrap it in a clean towel and squeeze hard until you remove most of the liquid; aim for about 150 g of squeezed zucchini.
- Beat the butter, granulated sugar, and brown sugar in a bowl for 2 to 3 minutes until light and fluffy. Scrape the bowl.
- Add the egg, lemon zest, lemon juice, and vanilla. Mix until smooth and creamy.
- Whisk the flour, baking powder, baking soda, salt, and cornstarch in a separate bowl. Keep the whisk handy for lumps.
- Add the dry ingredients to the wet on low speed until a few flour streaks remain. Fold in the squeezed zucchini and any mix-ins until the dough looks even.
- Chill the dough for 15 to 20 minutes while the oven finishes heating. This quick chill keeps the cookies thick and tender.
- Scoop 1.5 tablespoon mounds onto the sheets, spacing 2 inches apart. You get about 24 cookies.
- Bake one sheet at a time for 10 to 12 minutes until edges set and tops look matte with pale golden bottoms. Rotate the sheet at the 7-minute mark for even baking.
- Cool the cookies on the sheet for 5 minutes, then move them to a wire rack. Let them cool fully before glazing.
- Whisk the powdered sugar, lemon juice, zest, and a pinch of salt until the glaze runs in slow ribbons. Adjust with a splash of milk or extra sugar to hit a thick drizzle.
- Spoon or drizzle glaze over the cooled cookies. Let the glaze set for 15 to 20 minutes before serving.
Tips & Tricks
- Squeeze the zucchini very well; excess water makes flat, greasy cookies.
- Zest the lemons right over the bowl to catch the flavorful oils.
- Use room temperature butter and egg so the dough emulsifies and bakes evenly.
- Add cornstarch for plush, soft centers.
- Chill the dough if your kitchen runs warm or if the first batch spreads too much.
- Want sharper lemon flavor without extra juice? Add 1/4 teaspoon lemon extract or a tiny pinch of citric acid.
- Bake a test cookie to check spread and timing, then adjust the rest.
- For gluten-free, use a 1:1 baking blend and rest the dough 20 minutes before baking.
- For dairy-free, use plant butter sticks and thin the glaze with water or dairy-free milk.
- Use a cookie scoop for uniform size, then rotate pans for consistent browning.
What to Serve with Lemon Zucchini Cookies
Serve these lemon zucchini cookies with iced tea, lemonade, or a strong cup of coffee for a bright finish. Pair them with fresh berries and a spoon of yogurt for a breezy dessert plate. You can even sandwich two cookies with vanilla ice cream for a summer treat. They also fit a brunch spread next to frittata and fruit salad.
Make-Ahead and Storage
- Store glazed cookies in an airtight container at room temperature for 3 days; separate layers with parchment to protect the glaze.
- Refrigerate for up to 6 days and let the cookies come to room temperature before serving.
- Freeze unglazed baked cookies for up to 3 months; thaw at room temperature, then glaze.
- Freeze scooped dough balls on a sheet until firm, then bag for up to 3 months; bake from frozen and add 2 to 3 minutes to the time.
- Refresh day-old cookies in a 300°F oven for 4 to 5 minutes, then cool for a few minutes for the best texture.
