Lemon poppy seed cookies with frosting.

These are one of the BEST cookies that I have ever made.

With a delicious and bright lemon flavor in every bite, you won’t want to stop eating them.

However, the lemon flavor is perfectly contrasted with the smooth and silky vanilla bean buttercream frosting on top.

Trust me, each bite is better than the last!

Main Ingredients

Ingredients measured out in bowls to make poppy seed cookies.

The flavor. Each bite is bursting with an incredible lemon flavor.

By adding both lemon zest AND juice to the cookie, the lemon flavor is strong but not overpowering.

And when paired with the vanilla frosting, it has a flawless balance of flavors.

Perfect texture. The cookie is soft and tender in every bite.

It is perfectly crumbly while still being moist. The cookie melts in your mouth and pairs well with the smooth vanilla buttercream frosting on top.

Simple. Both the cookie batter and frosting are incredibly easy to make.

The cookie batter requires just one bowl and an electric hand mixer to bring it all together.

How to Make Lemon Poppy Seed Cookies

  1. Preheat the oven to 350 degrees F
  2. To a large mixing bowl, add the granulated sugar and lemon zest
  3. Rub the zest into the sugar using your fingers to release the oils
  4. Add the softened butter and mix until smooth and creamy using an electric hand mixer
  5. Next, add in the lemon juice, egg, and vanilla extract
  6. Mix until fully combined
  7. Add the poppy seeds and mix into the wet ingredients
  8. Now, add in the flour, baking powder and baking soda
  9. Mix using the electric hand mixer until combined
  10. Use a 2 tbsp cookie scoop to portion out the dough on a cookie sheet lined with parchment paper
  11. Bake for about 15 minutes until the cookies rise with golden edges/bottom

  20. Serve and enjoy!

Frequently Asked Questions

Can these cookies be made gluten-free friendly?

Yes! Swap the flour for Gluten Free All Purpose Flour at a 1:1 ratio.

(Note: I haven’t tested this swap in this specific recipe but has typically worked in other cookie recipes. To be safe, start by adding only 1 1/4 cup of flour then slowly add in the rest until it reaches the desired texture).

What is the difference between vanilla extract and vanilla paste?

Both vanilla extract and paste have similar vanilla flavor profiles, however, they differ in consistency and flavor intensity. 

Vanilla paste is a thicker, more concentrated blend, often including ground vanilla beans, and has a more intense vanilla flavor than vanilla extract. 

Vanilla extract, on the other hand, is a liquid infusion of vanilla bean flavor. 

Can I omit the poppy seeds?

Of course, if you prefer to not add them into the batter, it will not impact the final result of the cookie. They will still be delicious!

What is the best way to store the leftover cookies?

Store in a sealed, airtight container at room temperature for up to 4 days or in the fridge for 7 days.

Can I freeze the cookies?

You can wrap each cookie individually in plastic wrap before placing them in an airtight container to store in the freezer (up to 1 month for ultimate freshness).
