Lemon Zucchini Cookies Ingredients
For the Cookies
- All-Purpose Flour – Provides structure; you can substitute with gluten-free flour for a gluten-free option.
- Baking Powder – Acts as a leavening agent for lightness; avoid substitutions for the best texture.
- Salt – Enhances flavor; use sea salt or kosher salt interchangeably.
- Unsalted Butter – Adds richness and moisture; margarine or a dairy-free alternative works in a pinch.
- Granulated Sugar – This sweetener contributes to the cookie’s texture; consider brown sugar for a deeper flavor.
- Egg – Binds ingredients and adds moisture; a flax egg (1 tbsp ground flaxseed + 2.5 tbsp water) can be used for a vegan option.
- Lemon Zest – Imparts bright flavor; fresh zest is preferred for the best results.
- Grated Zucchini – Adds moisture and nutrition; medium-sized zucchini is ideal without substitutions.
For the Glaze
- Powdered Sugar – Used for glazing; cornstarch can help achieve a similar consistency if necessary.
- Lemon Juice – Provides tartness; freshly squeezed lemon juice is best, so avoid the bottled version.
These Lemon Zucchini Cookies not only make good use of that extra zucchini lurking in your kitchen but also showcase the delightful marriage of flavors that will brighten your day!
Step‑by‑Step Instructions for Lemon Zucchini Cookies
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). While the oven heats up, prepare your cookie sheet by greasing it or lining it with parchment paper to prevent sticking. The aroma of the warming oven will set the mood for baking these delightful Lemon Zucchini Cookies.
Step 2: Mix Dry Ingredients
In a medium-sized mixing bowl, whisk together the all-purpose flour, baking powder, and salt until well blended. This dry mixture lays the groundwork for the cookies, ensuring an even distribution of leavening agents. Set the bowl aside to focus on the wet ingredients.
Step 3: Cream Butter and Sugar
In a large bowl, beat the softened unsalted butter and granulated sugar together using a hand mixer or stand mixer. Continue mixing for about 2-3 minutes until the mixture turns light and fluffy, which indicates that the sugar is well incorporated into the butter, adding that rich texture to your Lemon Zucchini Cookies.
Step 4: Add Egg and Lemon Zest
Now, add in one egg and the fragrant lemon zest to the creamed butter and sugar mixture. Mix on medium speed for another 2-3 minutes until everything is smoothly combined, and you’ll see a beautiful, bright mixture that captures the zestiness that makes these cookies so special.
Step 5: Combine Mixtures
Gradually introduce the dry ingredient mixture to the wet ingredients. Stir gently until just incorporated; be careful not to overmix, as this can lead to dense cookies. A few flour streaks remaining is perfectly fine for these Lemon Zucchini Cookies, as they will finish mixing in the next steps.
Step 6: Fold in Zucchini
Using a spatula, carefully fold in the grated zucchini into the cookie dough. Ensure the zucchini is evenly distributed throughout the mixture without crushing it too much; this moisture will be key to achieving that soft and tender texture you want from your Lemon Zucchini Cookies.
Step 7: Shape Cookies
Using a tablespoon or cookie scoop, drop rounded tablespoonfuls of dough onto the prepared cookie sheet. Leave enough space between them (about 2 inches apart) as they will spread while baking. This step ensures your Lemon Zucchini Cookies have space to bloom into delightful nuggets.
Step 8: Bake
Slide the cookie sheet into the preheated oven and bake for 10-12 minutes. Keep an eye on them; you’re looking for a lightly browned edge with a slightly soft center. Remember, pulling them out when slightly underbaked will give you that sought-after soft texture in each cookie.
Step 9: Cool and Glaze
After baking, allow the cookies to cool on the baking sheet for a few minutes, then transfer them to a wire rack for complete cooling. Once they are just warm, drizzle your lemon glaze made from powdered sugar and lemon juice over them, adding that zesty finish to your refreshing Lemon Zucchini Cookies.
Make Ahead Options
These Lemon Zucchini Cookies are perfect for meal prep enthusiasts! You can grate the zucchini and mix your dry ingredients up to 24 hours in advance, storing them separately in airtight containers in the refrigerator. This prep helps save time on busy days. Additionally, shape the cookie dough and place it on the baking sheet, then cover and refrigerate for up to 3 days before baking. When you’re ready to enjoy, simply bake as directed, adding a few extra minutes if baking straight from the fridge to ensure they are just as delicious and soft as fresh-baked cookies. The preparation makes your cookie baking effortless, letting you savor the delightful flavors whenever you desire!

Lemon Zucchini Cookies Recipe FAQs
How do I choose the best zucchini for cookies?
When selecting zucchini, look for medium-sized ones without dark spots all over. These will have a better texture and less seediness, making them perfect for baking. I often pick ones that feel firm and heavy for their size, which indicates they are fresh and full of moisture.
What’s the best way to store leftover Lemon Zucchini Cookies?
Absolutely! You can store your cookies in an airtight container at room temperature for up to 3 days. If you’re in a warmer climate, I recommend refrigerating them for up to 5 days to keep them fresh and prevent spoilage. Always ensure they’re completely cooled before storage to maintain their soft texture.
Can I freeze Lemon Zucchini Cookies? If so, how?
Yes, you can freeze these cookies! Individually freeze the cookies (without glaze) on a baking sheet for about an hour until firm. Then, transfer them to a freezer-safe bag or container. They’ll keep well for up to 3 months. When you’re ready to enjoy them, simply thaw at room temperature or warm them in the microwave for just a few seconds to bring back that delightful softness.
What if my cookies come out too dry or dense?
No worries! If you find your cookies dry, it could be due to overmixing the dough after adding the flour—this can lead to tough cookies. To avoid this, mix just until you see no more flour streaks. Also, ensure you didn’t squeeze excess moisture from the zucchini; it’s key for keeping the cookies moist and cake-like.
Are Lemon Zucchini Cookies safe for people with allergies?
Great question! These cookies do contain common allergens such as wheat and eggs. For those with dietary restrictions, you can substitute the flour with a gluten-free blend and replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water) for a vegan option. Always double-check ingredients you choose to ensure they’re allergy-friendly for all your guests!
