Easy Lemon Zucchini Cookies

Finding dessert recipes that combine fresh vegetables with sweet flavors can be tricky, especially when you’re trying to sneak more produce into your family’s diet. Let’s face it – most of us struggle to use up all those garden zucchini during the summer months, and there are only so many loaves of zucchini bread one family can eat.

That’s why these lemon zucchini cookies have become such a favorite in our house. They’re soft and sweet with a bright citrus twist, easy to whip up in under an hour, and best of all – they’re a clever way to use up that extra summer squash while satisfying your cookie cravings.

What Kind of Zucchini Should I Use?

For baking cookies, medium-sized zucchini are your best bet since they tend to have fewer seeds and more flesh than their larger counterparts. The smaller ones work great too, but try to avoid the giant zucchini you might find at the end of summer – they can be watery and have lots of large seeds that could affect your cookie texture. When you’re grating the zucchini, there’s no need to squeeze out the moisture like you would for bread or muffins, since that extra moisture actually helps keep these cookies soft. Just make sure to peel the zucchini first (as the recipe suggests) to keep the green bits from showing up in your finished cookies, unless you don’t mind the speckled look!

Options for Substitutions

Need to make some swaps? Here are some helpful substitutions for these zucchini cookies:

• All-purpose flour: You can use whole wheat pastry flour for a nuttier taste, or for gluten-free needs, try a 1:1 gluten-free flour blend. Just note that the texture might be slightly different.
• Butter: For dairy-free options, use coconut oil or dairy-free butter alternatives in equal amounts. Just make sure they’re at room temperature too.
• Zucchini: Yellow summer squash works perfectly as a 1:1 replacement. Just be sure to peel and grate it the same way. Remember to squeeze out excess moisture regardless of which you use.
• Egg: For a vegan version, try using a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) or ¼ cup of mashed banana.
• Lemon zest and juice: While fresh lemon gives the best flavor and is recommended, you can use lime for a different citrus twist. For the glaze, you can thin the powdered sugar with milk if you’re out of lemon juice.

Watch Out for These Mistakes While Baking

The biggest challenge when making zucchini cookies is dealing with excess moisture – be sure to squeeze out as much liquid as possible from your grated zucchini using a clean kitchen towel or several layers of cheesecloth, otherwise your cookies might spread too much and become cake-like. Another common mistake is overmixing the dough once you’ve added the flour, which can lead to tough cookies – mix just until the ingredients are combined and no dry flour remains visible. For the perfect lemon flavor, don’t skip zesting your lemons before juicing them, and avoid using bottled lemon juice which lacks the bright, fresh taste of real citrus. When making the glaze, add the lemon juice gradually to the powdered sugar until you reach the right consistency – it should be thick enough to stay on top of the cookies without running off completely.

What to Serve With Lemon Zucchini Cookies?

These light and fresh cookies are perfect for afternoon tea or as a sweet snack with your favorite hot beverage. A cup of Earl Grey tea makes an especially nice pairing since its bergamot notes complement the lemon in the cookies really well. If you’re serving these at a party or gathering, try setting them out alongside some fresh berries or a scoop of vanilla ice cream – the combination of flavors is just right for a summer dessert. For a fun breakfast treat, these cookies taste great with a cold glass of milk or a hot cup of coffee with a splash of cream.

Storage Instructions

Keep Fresh: These zucchini cookies stay nice and soft when kept in an airtight container at room temperature for up to 3 days. If you live in a warm climate, you might want to pop them in the fridge instead, where they’ll keep for about 5 days. Just place a piece of bread in the container to help maintain their moisture!

Freeze: Good news – these cookies freeze really well! Once they’re completely cooled and the glaze has hardened, layer them between pieces of wax paper in a freezer container. They’ll stay fresh for up to 3 months. Just remember to freeze them before adding the glaze for best results.

Thaw: When you’re ready to enjoy your frozen cookies, just take out what you need and let them thaw at room temperature for about 30 minutes. If you froze them without glaze, you can add it once they’re completely thawed. They’ll taste just as good as the day you made them!

Ingredients

For the cookies:

• 3/4 cup unsalted butter (softened at room temperature)
• 3/4 cup granulated sugar
• 1/2 tsp salt
• 1 large egg
• 2 cups all-purpose flour (I use King Arthur all-purpose flour)
• 1 cup shredded zucchini
• 1 tsp grated lemon zest (freshly grated for best flavor)
• 1 tsp baking powder

For the glaze:

• 1/2 tsp lemon zest
• 1 1/2 tbsp fresh lemon juice
• 1 cup confectioners’ sugar (sifted to prevent lumps)

Step 1: Preheat the Oven and Prepare Baking Sheet

Preheat your oven to 375°F (190°C).

Prepare a cookie sheet by greasing it lightly, or line it with parchment paper if you prefer easy cleanup.

Step 2: Mix Dry Ingredients

• 2 cups all-purpose flour
• 1 tsp baking powder
• 1/2 tsp salt

In a medium mixing bowl, combine the all-purpose flour, baking powder, and salt.

Whisk these together well to ensure the leavening agents are evenly distributed, then set the bowl aside for later use.

Step 3: Cream Butter, Sugar, and Incorporate Wet Ingredients

• 3/4 cup unsalted butter, softened
• 3/4 cup granulated sugar
• 1 large egg
• 1 tsp grated lemon zest

In a large bowl, cream the softened unsalted butter and granulated sugar together until the mixture is light and fluffy, about 2-3 minutes using an electric mixer or a sturdy spoon.

Add the egg and grated lemon zest and continue beating for another 2-3 minutes until everything is well blended.

I like to zest the lemon directly over the bowl to capture all the fragrant oils.

Step 4: Combine Wet and Dry Ingredients, Stir in Zucchini

• dry ingredients from Step 2
• wet mixture from Step 3
• 1 cup peeled, shredded zucchini

Gradually add the flour mixture from Step 2 into the butter mixture from Step 3, stirring just until combined.

Be careful not to overmix, which can make the cookies tough.

Next, fold in the peeled, shredded zucchini with a spatula until it is evenly distributed throughout the dough.

Step 5: Portion and Bake the Cookies

• cookie dough from Step 4

Drop the dough by rounded tablespoonfuls onto the prepared cookie sheet, spacing the cookies a couple of inches apart.

Bake in the preheated oven for 10-12 minutes, or until the tops and edges are lightly browned.

Remove from the oven and let them cool on the baking sheet for a few minutes before transferring to a wire rack.

I like to slightly underbake them for extra softness.

Step 6: Glaze and Finish the Cookies

While the cookies are partially cooled on the rack, drizzle your prepared glaze over them.

Allow the glaze to set before serving.

(The recipe description mentions a glaze but doesn’t list ingredients.

Consider making a simple glaze with powdered sugar and a bit of lemon juice for a citrusy touch.)
