Ingredients & Supplies You'll Need

When it comes to making delicious lemon poppy seed cookies, there are some key ingredients and supplies you'll need to have on hand. Here's a rundown of everything you'll need to get started:

Ingredients

First and foremost, you'll need the right ingredients to make your cookies. Here's what you'll need:

• Flour - Basic all-purpose flour works just fine here.
• Baking soda
• Salt
• Unsalted Butter - Softened at room temperature.
• Granulated Sugar
• Eggs - It's best if you start with room temperature eggs.
• Lemon zest
• Fresh Lemon Juice
• Vanilla extract
• Poppy seeds
• Powdered sugar

In addition, you'll need some basic supplies including mixing bowls, a stand mixer, baking sheets, and parchment paper. It's also helpful to have a zester!

How to Make Lemon Poppy Seed Cookies

To get started, preheat your oven to 350 F and line a cookie sheet with parchment paper. In a medium bowl, whisk together the flour, baking soda, and salt, and set it aside.

Next, in the bowl of a stand mixer fitted with the paddle attachment, beat the butter and sugar until light and fluffy. Then, add the eggs, lemon zest, lemon juice, and vanilla, and beat again until everything is well combined.

In 2-3 smaller additions, add the flour mixture to the bowl, mixing well after each addition. Then, stir in the poppy seeds until they are evenly distributed throughout the dough.

Using a tablespoon, drop the cookies onto the prepared baking sheet about 2 inches apart. Bake in the preheated oven for 8-10 minutes or until slightly golden brown around the edges.

While the cookies are baking, prepare the glaze by mixing the powdered sugar and lemon juice together until smooth. Use more or less juice depending on the desired consistency.

Once the cookies are done, allow them to cool completely before drizzling or piping the glaze over the top. And that's it! You now have delicious lemon poppy seed cookies to enjoy.

Helpful Tips & Tricks

Use fresh lemon! 

It might be tempting to use bottled lemon juice or skip the zest, but trust me, the fresh lemon flavor is worth it. It only takes a minute to zest a lemon - just do it.

Don't overmix. 

When adding the dry ingredients, mix them in slowly and just until the dough comes together. Overmixing can lead to tough cookies. And if you're having trouble with the dough sticking to your hands, try dusting them with a little flour.

Storing the Cookies

If you plan on eating your cookies within five days, simply store them in an airtight container at room temperature. This will keep them fresh and prevent them from getting stale.

If you want to keep your cookies for longer than five days, you can freeze them. First, let the cookies cool completely to room temperature. Then, store them in a freezer-safe container for up to three months. When you're ready to enjoy them, simply thaw them at room temperature for a few hours.

Alternatively, you can freeze the cookie dough for baking later. Roll the dough into balls and freeze in a single layer on a baking sheet. Then transfer to freezer bags or another airtight container for storage.

If you're storing multiple layers of cookies in the same container, make sure to separate them with a layer of parchment paper. This will prevent them from sticking together and getting damaged.

Variations & Substitutions

Add mix-ins. 

These cookies are delicious as is, but you can also try adding in some chopped nuts, dried cranberries, or even chocolate chips.

Try it with orange zest. 

Substitute the lemon juice and zest for orange juice and zest for a new citrusy twist.

Add almond flavor. 

Try adding 1 tsp of almond extract and chopped almonds for an Almond Poppy Seed Cookie.

Make it gluten free. 

If you're gluten intolerant or just prefer to avoid gluten, you can easily make these cookies gluten-free by using a 1:1 gluten-free flour blend instead of all-purpose flour. 

Make it dairy-free. 

To make these cookies dairy-free, simply replace the butter with a vegan butter substitute or coconut oil. You can also use non-dairy milk, such as almond or soy milk, instead of regular milk.
