Ingredients:

2 and 1/4 cups (281g) all-purpose flour, spooned and leveled
1 Tablespoon (8g) cornstarch
1/4 teaspoon salt
14 Tablespoons (200g) unsalted butter, softened to room temperature (see Note)
3/4 cup (150g) granulated sugar
1 Tablespoon fresh lemon zest
1 Tablespoon fresh lemon juice
1 large egg, at room temperature
1 teaspoon vanilla bean paste (or vanilla extract)
1/2 cup (100g) granulated sugar
1/2 cup (140g) homemade lemon curd or store-bought
1 cup (120g) confectioners’ sugar
2 Tablespoons (30ml) fresh lemon juice

Preparing the Lemon Thumbprint Dough

Let’s start by creating the base for our delightful Lemon Thumbprints. This dough is buttery, slightly crisp, and perfectly balanced to complement the bright lemon filling.

Mixing the Dry Ingredients

In a medium-sized bowl, whisk together the 2 and 1/4 cups of all-purpose flour, 1 tablespoon of cornstarch, and 1/4 teaspoon of salt. Whisking these dry ingredients ensures they are evenly distributed, which is crucial for a consistent cookie texture. Set this bowl aside for now.

Creaming the Butter and Sugar

In a large bowl, using an electric mixer (stand mixer with paddle attachment or a hand mixer), cream together the 14 tablespoons of softened unsalted butter and the 3/4 cup of granulated sugar. It’s important that your butter is truly softened – not melted. It should yield to gentle pressure but still hold its shape. This process of creaming incorporates air into the butter and sugar, which contributes to the cookie’s tender crum extractb and prevents it from being too dense. Beat this mixture on medium-high speed until it becomes light and fluffy, which usually takes about 3 to 5 minutes.

Incorporating Wet Ingredients and Flavorings

Once the butter and sugar are beautifully creamed, it’s time to add the flavorings and the egg. Add the 1 tablespoon of fresh lemon zest and 1 tablespoon of fresh lemon juice to the creamed mixture. The zest provides a wonderful burst of aromatic lemon oil, while the juice adds a touch of tang. Next, add the large egg and the 1 teaspoon of vanilla bean paste (or vanilla extract). If you’re using vanilla bean paste, you’ll get little flecks of vanilla throughout your cookie, which is lovely. Beat everything together on medium speed until just combined and smooth. Scrape down the sides of the bowl periodically to ensure everything is incorporated.

Combining Wet and Dry Ingredients

Now, gradually add the dry ingredients from step 1 to the wet ingredients in the large bowl. Mix on low speed until just combined. Be careful not to overmix at this stage. Overmixing can develop the gluten in the flour too much, resulting in tough cookies. Stop mixing as soon as you no longer see streaks of flour. The dough will be soft and slightly sticky.

Chilling and Shaping the Dough

Turn the dough out onto a lightly floured surface. Gently bring the dough together with your hands to form a cohesive mass. Divide the dough into approximately 1-inch balls. Roll each ball between your palms to create smooth spheres. Place these dough balls onto a parchment-lined baking sheet, spacing them about 2 inches apart. You can use a lightly floured thumb or the end of a wooden spoon to make an indentation in the center of each cookie, creating the “thumbprint.” This indentation is where our luscious lemon curd will reside. Once shaped and indented, cover the baking sheet tightly with plastic wrap and refrigerating the dough for at least 1 hour, or preferably 2 hours. This chilling step is crucial. It firms up the butter, which prevents the cookies from spreading too much during baking and makes them easier to handle. You can also chill the dough for up to 2 days at this point.

Baking the Lemon Thumbprint Cookies

With our dough prepped and chilled, it’s time to bake them to golden perfection.

Baking the Cookies

When you’re ready to bake, preheat your oven to 350°F (175°C). Remove the chilled dough balls from the refrigerator. If the indentations have closed up slightly during chilling, gently press them again with your thumb or the back of a small spoon. Place the baking sheet in the preheated oven and bake for 12 to 15 minutes, or until the edges of the cookies are lightly golden brown and the centers are still slightly soft. The cookies will continue to set as they cool. Do not overbake them.

Preparing the Lemon Glaze and Filling

While the cookies are baking or cooling, let’s prepare the sweet and tangy lemon glaze and gather our lemon curd.

Making the Lemon Glaze

In a small bowl, whisk together the 1 cup of confectioners’ sugar and the 2 tablespoons of fresh lemon juice. Start with 2 tablespoons of lemon juice and add more, a teaspoon at a time, until you reach your desired consistency. You want a glaze that is thick enough to coat the back of a spoon but thin enough to drizzle. If it’s too thick, add a tiny bit more lemon juice. If it’s too thin, add a bit more confectioners’ sugar.

Filling the Thumbprints

Once the cookies have baked and cooled on the baking sheet for about 5 minutes, carefully transfer them to a wire rack to cool completely. It’s important that the cookies are completely cool before filling them with lemon curd, otherwise the curd might melt or become too runny. Once the cookies are fully cooled, gently spoon about 1/2 teaspoon of the 1/2 cup of homemade or store-bought lemon curd into the indentation of each cookie. Don’t overfill, as it can spill out.

Finishing Touches and Serving

The final steps bring all the elements together for a beautiful and delicious cookie.

Glazing and Serving

Once the lemon curd is in place, you can either drizzle the prepared lemon glaze over the top of the cookies, letting it cascade down the sides slightly, or you can dip the tops of the filled cookies into the glaze. Alternatively, if you prefer a simpler approach, you can skip the glaze entirely and simply dust the cooled cookies with a little extra confectioners’ sugar. Allow the glaze to set for about 15-20 minutes before serving. These Lemon Thumbprints are best enjoyed within a few days and stored in an airtight container at room temperature.

Don’t be afraid to get creative and make these Lemon Thumbprints your own!

Frequently Asked Questions:

Q1: My thumbprints sank or cracked during baking. What went wrong?

This can happen for a few reasons. Ensure your dough is well-chilled before forming the cookies, as this helps maintain their shape. When pressing the thumbprint, try not to press too deeply, and use a floured finger or the back of a small spoon to avoid tearing the dough. Overmixing the dough can also contribute to cracking. If the dough becomes too soft, chill it again before proceeding.

Q2: Can I make Lemon Thumbprints ahead of time?

Absolutely! Baked and cooled Lemon Thumbprints can be stored in an airtight container at room temperature for up to 3-4 days. If you’re filling them with jam or frosting, it’s best to do so closer to serving time to prevent the cookies from becoming soggy. The dough can also be made ahead and refrigerated for up to 2 days, or frozen for up to a month.
