Can I use bottled lemon juice instead of fresh?

Fresh lemon juice provides the brightest flavor, but in a pinch, bottled will work. The difference is subtle, especially with the lemon curd and zest still providing plenty of lemon flavor. If using bottled, reduce the amount slightly as it can be more concentrated.

Why did my cookies spread too much?

The most common reason is that the dough wasn't chilled long enough. These cookies have a high butter content, which makes them delicious but also prone to spreading if not properly chilled. Another possibility is that your butter was too warm when making the dough. Always make sure to chill the shaped cookies again while the oven preheats.

Can I make these gluten-free?

Yes! You can substitute a cup-for-cup gluten-free flour blend. The texture might be slightly different, but many bakers report great results. You may need to add an extra tablespoon of flour to prevent spreading, as gluten-free flours sometimes behave differently.

The lemon curd bubbled and spread during baking. How can I prevent this?

Make sure your thumbprint indentations are deep enough and wide enough to hold the curd. Also, don't overfill them - 1/2 teaspoon is the perfect amount. If you're still having trouble, try freezing the filled cookies for 10 minutes before baking.

Why You’ll Love This Recipe

Make-Ahead Friendly: The dough can be prepared up to 3 days in advance and kept in the refrigerator, perfect for planning ahead for parties or when you know you’ll be short on time.
Impressive Yet Simple: These cookies look like they came from a fancy bakery, but they’re actually quite straightforward to make. The thumbprint technique is fun and foolproof!
Versatile: While lemon curd is the star filling, you can easily swap in your favorite fruit preserves for a different flavor profile whenever you want.

Ingredients You’ll Need

All-purpose flour: The foundation of our cookies, providing structure and that perfect tender crumb.
Cornstarch: The secret to achieving that melt-in-your-mouth texture that makes these cookies irresistible.
Butter: Use unsalted butter so you can control the salt content. It creates richness and helps the cookies spread just the right amount.
Granulated sugar: For sweetness in the dough and for rolling the cookies before baking, giving them a subtle sparkle and crunch.
Fresh lemon: Both the zest and juice are essential for infusing the cookies with authentic lemon flavor.
Egg: Acts as a binder for the dough and adds richness to the texture.
Vanilla bean paste: Adds depth of flavor with those beautiful specks of vanilla bean. Regular extract works too, but the paste takes these cookies to the next level.
Lemon curd: The star of the show! This tangy, smooth filling creates a perfect contrast to the sweet cookie. Homemade is amazing, but store-bought works well for convenience.
Confectioners’ sugar: The base for our simple glaze that adds one more layer of lemon flavor and a beautiful finishing touch.

How to Make Lemon Thumbprints

Step 1: Prepare the Dough

Whisk together your dry ingredients (flour, cornstarch, and salt) in a medium bowl and set aside. In a larger bowl, beat butter and sugar until creamy and light. Add lemon zest, juice, egg, and vanilla, beating until combined. Don’t worry if the mixture looks curdled at this point! Gradually mix in your dry ingredients until you have a soft, creamy dough.

Step 2: Chill the Dough

Cover the dough and refrigerate for at least 3 hours. This step is absolutely crucial! The chilling firms up the butter and prevents the cookies from spreading too much during baking. It also develops the flavors and makes the dough easier to handle.

Step 3: Shape and Fill

Roll the chilled dough into tablespoon-sized balls, then coat each ball in granulated sugar for a subtle crunch and sparkle. Arrange them on lined baking sheets, then make an indentation in the center of each cookie with your thumb. Fill each indentation with about 1/2 teaspoon of that gorgeous lemon curd.

Step 4: Final Chill and Bake

Chill the shaped cookies while your oven preheats to 350°F. This prevents them from spreading too much in the oven. Bake for 12-13 minutes until the edges are just set and barely beginning to turn golden. Let them cool on the baking sheet for 5 minutes before transferring to a wire rack.

Step 5: Glaze

Once the cookies are completely cool, whisk together confectioners’ sugar and lemon juice to make a smooth glaze. Drizzle this over the cookies for an extra hit of lemon flavor and a beautiful finish. Let the glaze set for about 30 minutes before stacking or storing.

Pro Tips for Making the Recipe

Cold Butter Chunks: If your dough seems too soft after mixing, cut in a few small pieces of cold butter and fold through the dough before chilling.
Perfect Indentations: If the indentations start to lose their shape during baking, press them down again gently with the back of a teaspoon right when they come out of the oven.
Even Sizing: Use a small cookie scoop for uniform cookies that will bake evenly.
Filling Technique: A small teaspoon or plastic bag with the corner snipped off works perfectly for adding the lemon curd neatly.
Don’t Overfill: Keep the curd below the rim of the indentation to prevent it from bubbling over during baking.
