These lemon thumbprint cookies are a lemon lovers’ dream cookie! Enjoy sweet, soft lemon sugar cookies filled with lemon curd and drizzled with lemon icing. I like to make the lemon curd from scratch because the flavor is superior (honestly, it’s just so good!), but feel free to use store-bought. Instead of lemon curd, you can substitute raspberry, strawberry, or apricot preserves/jam.
A sunny burst of citrus is just the thing to brighten up a gray winter day and add a pop of unexpected flavor to a holiday cookie tray. Among the deep dark flavors of chocolate and spice, like gingerbread cookies, Andes mint chocolate cookies, or chocolate ginger sparkle cookies, these lemon thumbprints shine like twinkly lights in the night. 😉
Loads of Lemon
These lemon thumbprints are flavored with real lemon all the way through, from the cookie dough to the lemon curd filling to the icing on top. Fresh lemon juice and zest are key to all that flavor.
Make the Homemade Lemon Curd First
Have you made lemon curd before? It’s delicious on so many dessert recipes, like atop this lemon cheesecake or pavlova. You can use store-bought lemon curd in these cookies in a pinch, but I encourage you to try making it from scratch—it’s surprisingly easy, takes just 10 minutes on the stove, and tastes so much better!
You could also play around with flavors and try filling the lemon thumbprints with fruit jam, like I use in these peanut butter & jam thumbprint cookies.
Here’s What You Need for These Lemon Thumbprint Cookies:
Make the Lemon Cookie Dough & Chill
The dough comes together quickly with an electric mixer, which is required for creaming the butter and sugar together.
This creamy dough needs to chill for at least 3 hours before it’s ready to be rolled and shaped.
How to Shape & Fill Lemon Thumbprints
Once the dough has chilled, you can shape the cookies. Scoop the dough with a Tablespoon and then roll the dough into balls. Roll the cookie dough balls in granulated sugar before placing on a baking sheet.
Use your thumb to make an indentation in the center of each cookie dough ball, then spoon about 1/2 teaspoon of lemon curd into each. Bake the cookies for about 12–13 minutes.
Optional Lemon Icing Is the Icing on the… Cookies
While it’s entirely optional, I love these cookies with a drizzle of icing on top. It’s just that little something extra that makes them look like you bought them from a fancy bakery. Plus, it tastes fantastic!
You need just 2 ingredients: confectioners’ sugar and fresh lemon juice. Whisk it together until smooth, and drizzle it on the cooled cookies. I used a squeeze bottle to apply this sweet finishing touch, but you can simply use a spoon or fork.
The icing sets in about 30 minutes or so, and then you can stack and store the cookies.
Lemon Thumbprint Cookies Recipe
Ingredients You’ll Need
Instructions
- In a medium bowl, whisk together the flour, cornstarch, and salt until combined. Set aside.
- In a large bowl using a handheld or a stand mixer fitted with a paddle attachment, beat the butter and 3/4 cup (150g) granulated sugar together on medium-high speed until creamed, about 1 minute. Add the lemon zest, lemon juice, egg, and vanilla bean paste and beat on high speed until combined, about 1 minute. The wet ingredients will look curdled, but will smooth out when you add the dry ingredients. Scrape down the sides and up the bottom of the bowl and beat again as needed to combine.
- Add the dry ingredients to the wet ingredients and mix on low speed until combined. Dough will be very creamy. Cover and refrigerate for at least 3 hours, and up to 3 days. Chilling is imperative for this soft dough.
- Line large baking sheets with parchment paper or silicone baking mats. Make room in the refrigerator for baking sheets, so the shape cookies can chill as the oven preheats in step 7.
- Place granulated sugar in a small bowl. Scoop cold dough (about 1 Tablespoon (18g) of dough each) and roll into balls. Roll each dough ball in granulated sugar and place 2 inches apart on lined baking sheets.
- Use your thumb to make an indentation in the center of each cookie dough ball. Fill each with 1/2 teaspoon of lemon curd.
- . Place baking sheets with unbaked cookies in the refrigerator while the oven preheats. (Or transfer all cookies to 1 baking sheet, or a few plates, if your refrigerator doesn’t have room. I recommend chilling the shaped cookies for a few minutes, to prevent over-spreading.)
- Once oven preheats, bake shaped cookies for 12–13 minutes, or until edges appear set and are very lightly beginning to brown. Remove from the oven and allow cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
- In a small bowl, whisk together confectioners’ sugar and lemon juice. Drizzle over cooled cookies. (You can use a spoon or fork for this, or a squeeze bottle.) Icing will set at room temperature after about 30 minutes, and then you can stack, store, transport, and gift the cookies.
- Cookies stay fresh covered at room temperature for up to 1 week.
Frequently Asked Questions
Yes, you can absolutely skip the lemon curd. Instead, try raspberry, apricot, or strawberry preserves/jam. Keep in mind that the lemon flavor won't be as strong without the lemon curd, so I recommend keeping the lemon icing on top. (For that pop of lemon flavor!)
If you want even more lemon flavor in your cookies, feel free to add 1/2 teaspoon of lemon extract to the cookie dough when you add the vanilla bean paste.
