Ingredients

Here’s what you’ll need to make a batch of these fresh and zesty cookies:
For the Cookies:
• 3/4 cup butter, softened
• 3/4 cup granulated sugar
• 1 large egg
• 1 teaspoon lemon zest
• 2 cups all-purpose flour

For the Lemon Glaze:
• 1 cup confectioners sugar
• 1 1/2 tablespoons lemon juice

Step-by-Step

Instructions

1. Preheat the Oven: Set your oven to 350°F (175°C). Lightly grease a baking sheet or line with parchment paper.
2. Cream Butter and Sugar: In the bowl of a stand mixer (or using a hand mixer), beat the butter and granulated sugar until light and fluffy. This step helps give the cookies their soft texture.
3. Add Egg and Lemon Zest: Beat in the egg and lemon zest until fully incorporated, filling your kitchen with a fresh citrus aroma.
4. Mix Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, and salt.
5. Combine Wet and Dry: Gradually stir the dry mixture into the wet ingredients until well blended.
6. Fold in Zucchini: Gently mix in the shredded zucchini and any optional nuts, taking care not to overmix.
7. Drop and Bake: Scoop tablespoon-sized portions of dough onto the prepared baking sheet, spacing them about 2 inches apart. Bake for 15–20 minutes or until lightly golden at the edges.
8. Prepare the Glaze: While the cookies bake, stir together confectioners sugar and lemon juice in a small bowl until smooth.
9. Cool and Glaze: Let the cookies cool completely on a wire rack before drizzling with the lemon glaze.

How to Serve

These cookies are versatile enough to enjoy in a variety of ways:
With Afternoon Tea: Perfect alongside a hot cup of tea or coffee.

Tips & Variations

Make Them Extra Lemony: Add an extra teaspoon of lemon zest to the dough or a few drops of lemon extract for a stronger citrus punch.
Nut-Free Version: Skip the nuts for a softer, more cake-like cookie.
Add a Spice Twist: A pinch of cinnamon or nutmeg pairs surprisingly well with the lemon flavor.
Double the Glaze: If you like your cookies sweeter, make extra glaze and give them a second drizzle after the first layer sets.
Mini Cookies: Use a smaller scoop for bite-sized treats—perfect for parties.

Storing & Freezing

Room Temperature: Store in an airtight container for up to 4 days. Place a piece of parchment paper between layers to keep the glaze from sticking.
Freezing the Dough: Drop the dough onto a baking sheet, freeze until solid, then store in a freezer-safe bag for up to 3 months. Bake from frozen, adding an extra minute or two to the bake time.
Freezing Baked Cookies: You can also freeze fully baked and glazed cookies. Wrap individually and store for up to 2 months. Thaw at room temperature.

Why Zucchini Works in Cookies

Zucchini is one of baking’s best-kept secrets. While it doesn’t add a strong flavor, it provides moisture and a delicate texture, resulting in cookies that stay soft for days. The vegetable’s mild taste allows the lemon to shine while adding subtle flecks of color for visual appeal. Plus, it’s a clever way to use up extra zucchini during the summer harvest.

Pairing Ideas

With Beverages: These cookies pair beautifully with iced tea, herbal infusions, or a sparkling lemonade. For something cozier, try chamomile or Earl Grey tea.
With Other Desserts: Serve alongside lemon bars or shortbread for a citrus-themed dessert platter.
With Savory Snacks: Believe it or not, these cookies also make a fun contrast to salty snacks like popcorn or roasted nuts.

Troubleshooting

Why are my cookies flat? Your butter may have been too soft, or you may have skipped chilling the dough if your kitchen is warm. Try refrigerating the dough for 15 minutes before baking.
Can I use yellow zucchini? Absolutely—it will taste the same but look slightly different.
Do I need to peel the zucchini? No, the peel is tender and adds lovely green flecks to the cookies. Just wash it well.
Can I make these vegan? Yes—use a plant-based butter substitute and a flax egg (1 tbsp ground flaxseed + 3 tbsp water).
Why is my glaze too runny? Add more confectioners sugar until you reach the desired consistency.

Frequently Asked Questions (FAQ)

Why are my cookies flat?
Flat cookies usually happen when the butter is too soft or the dough has been overmixed. If your kitchen is warm, try chilling the dough for 15–20 minutes before baking.

Can I use yellow zucchini instead of green?
Yes! Yellow zucchini works just as well and will give the cookies a slightly different color but the same flavor and texture.

Do I need to peel the zucchini?
No, peeling isn’t necessary. The skin is tender and adds pretty green flecks to the cookies—just wash it thoroughly before grating.

How do I keep the cookies from turning soggy?
After grating, gently pat the zucchini with a paper towel to remove excess moisture before adding it to the dough.

Can I make these cookies gluten-free?
Yes, you can replace the all-purpose flour with a cup-for-cup gluten-free flour blend. Make sure it includes xanthan gum for best results.

Is the lemon glaze necessary?
The glaze adds a bright, sweet-tart finish that elevates the cookies, but you can skip it if you prefer. A dusting of powdered sugar is a nice alternative.

Can I freeze the cookies?
Yes. Freeze baked cookies in an airtight container for up to 2 months, or freeze unbaked dough balls and bake them later with just a minute or two added to the bake time.

Do they actually taste like vegetables?
Not at all. The zucchini is mild in flavor—it simply keeps the cookies moist while allowing the lemon to shine.

Can I double the recipe?
Absolutely. Just bake in batches so the cookies have enough space to spread properly in the oven.
