What are Lemon Thumbprint Cookies?

Lemon thumbprint cookies are a type of shortbread cookie that is shaped by pressing a small indent (often with your thumb) into the center of the dough, which is then filled with lemon curd. The cookie itself is rich and buttery, with a crisp but tender texture that perfectly complements the bright, zesty lemon curd. These cookies are a wonderful mix of textures and flavors, combining the sweetness of the cookie with the tartness of the lemon filling. Whether you make your own lemon curd or use store-bought, these cookies are always a hit at parties or alongside an afternoon cup of tea.

Ingredients List for Lemon Thumbprint Cookies

Before you begin, gather all the necessary ingredients for the shortbread cookies and the lemon curd filling:

For the Shortbread Cookies:

• 2 cups all-purpose flour
• ½ teaspoon salt
• 1 cup (2 sticks) unsalted butter, softened
• ½ cup granulated sugar
• 1 teaspoon vanilla extract
• 1 tablespoon lemon zest (optional, for extra lemon flavor)

For the Lemon Curd (Homemade or Store-bought):

• ½ cup fresh lemon juice (about 2-3 lemons)

• ½ cup granulated sugar
• 4 large egg yolks
• 6 tablespoons unsalted butter, cut into small pieces

Alternatively, you can use store-bought lemon curd to save time.

Ingredients List for Lemon Thumbprint Cookies (Double Check)

Here’s a quick double-check to make sure you have everything:

For the Shortbread Cookies:

• Make sure your butter is softened for easy mixing.
• Lemon zest adds extra citrusy brightness to the cookies, but you can omit it if you prefer a more classic shortbread flavor.

For the Lemon Curd:

• Fresh lemon juice works best for a vibrant, fresh flavor, but bottled lemon juice can be used in a pinch.
• If you’re short on time, you can always use a jar of high-quality store-bought lemon curd.

Substitutions and Variations

Lemon thumbprint cookies are versatile, and you can easily make substitutions or variations to suit your taste or dietary preferences. Here are some ideas:

1. Flavored Variations:

• Orange Thumbprint Cookies: Swap out the lemon juice and zest for orange juice and zest to make orange curd and create a different citrus flavor.
• Lime Thumbprint Cookies: Use lime juice and zest for a tropical twist, or a combination of lemon and lime for a unique citrus blend.
• Jam-Filled Thumbprints: Instead of lemon curd, fill the cookies with your favorite jam—raspberry, apricot, or strawberry all work wonderfully.

1. Crumb Topping Variations:

• Coconut: Add shredded coconut to the cookie dough or sprinkle it on top before baking for added texture and a tropical flavor.
• Nuts: Roll the cookie dough in chopped nuts, like almonds or pecans, for a nutty flavor and crunchy texture.

1. Dietary Modifications:

• Gluten-Free: Use a gluten-free flour blend instead of all-purpose flour to make the cookies gluten-free.
• Vegan Version: Substitute the butter with a plant-based alternative and use a vegan lemon curd made with cornstarch or agar-agar as a thickener instead of egg yolks.

1. Texture Modifications:

• Powdered Sugar Coating: For an extra sweet finish, dust the cookies with powdered sugar after baking.
• Iced Thumbprint Cookies: Drizzle a simple lemon glaze made from powdered sugar and lemon juice over the cookies after they’ve cooled for added sweetness and decoration.

Step-by-Step Cooking Instructions

Follow these detailed instructions to make perfect lemon thumbprint cookies from scratch, with homemade lemon curd for the ultimate citrusy treat.

1. Make the Lemon Curd

• Whisk the ingredients: In a medium saucepan, whisk together the egg yolks, sugar, lemon juice, and lemon zest until combined.
• Cook the lemon curd: Place the saucepan over medium heat and cook the mixture, stirring constantly, for about 7-10 minutes, or until it thickens enough to coat the back of a spoon. Do not let it boil.
• Add the butter: Remove the curd from the heat and stir in the butter, one piece at a time, until fully melted and smooth.
• Strain the curd: For an extra-smooth curd, strain it through a fine-mesh sieve to remove any bits of egg.
• Chill: Transfer the lemon curd to a bowl, cover it with plastic wrap (pressed directly onto the surface to prevent a skin from forming), and refrigerate for at least 1 hour.

2. Make the Shortbread Dough

• Mix the dry ingredients: In a medium bowl, whisk together the flour and salt. Set aside.
• Cream the butter and sugar: In a large bowl, using an electric mixer, beat the softened butter and sugar together until light and fluffy, about 2-3 minutes.
• Add the flavorings: Beat in the vanilla extract and lemon zest (if using) until combined.
• Add the dry ingredients: Gradually add the flour mixture to the butter mixture, mixing on low speed until just combined. The dough will be soft but should come together.
• Chill the dough: Cover the dough with plastic wrap and refrigerate for at least 30 minutes to firm up, making it easier to shape.

3. Shape and Bake the Cookies

• Preheat the oven: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper.
• Form the dough balls: Roll the chilled dough into 1-inch balls (about 1 tablespoon of dough per cookie) and place them on the prepared baking sheets, spaced about 2 inches apart.
• Create the thumbprint: Using your thumb or the back of a small spoon, gently press an indent into the center of each dough ball.
• Bake the cookies: Bake the cookies for 10-12 minutes, or until the edges are lightly golden. The centers may puff up slightly during baking, so carefully re-press the indent while the cookies are still warm.
• Cool: Let the cookies cool on the baking sheets for a few minutes, then transfer them to a wire rack to cool completely.

4. Fill the Thumbprints with Lemon Curd

• Add the lemon curd: Once the cookies have cooled, spoon about ½ teaspoon of chilled lemon curd into the center of each cookie.
• Chill: Let the filled cookies chill in the refrigerator for 30 minutes to help the lemon curd set.

How to Cook Lemon Thumbprint Cookies: A Step-by-Step Guide

Here’s a quick summary of how to make these delicious lemon thumbprint cookies:

1. Lemon Curd: Whisk together lemon juice, zest, egg yolks, and sugar, cook until thickened, and stir in butter. Chill until firm.
2. Shortbread Dough: Cream butter and sugar, then mix in flour and flavorings to form the dough. Chill the dough to make it easier to shape.
3. Shape Cookies: Roll the dough into small balls, press a thumbprint into the center of each, and bake until lightly golden.
4. Fill Cookies: Spoon chilled lemon curd into the center of each cooled cookie and refrigerate until the filling sets.

Common Mistakes to Avoid

• Not Chilling the Dough: Chilling the dough is important to prevent the cookies from spreading too much during baking. Don’t skip this step!
• Overcooking the Lemon Curd: Be sure not to let the lemon curd come to a boil while cooking, as it can curdle and become grainy. Cook it gently over medium heat while stirring constantly.
• Skipping the Thumbprint: Re-press the thumbprints after baking if the indents puff up. This ensures the lemon curd has enough space to sit in the center of the cookie.

Serving and Presentation Tips

Here are some ideas to serve and present your lemon thumbprint cookies beautifully:

How to Serve Lemon Thumbprint Cookies

• Serve Chilled or Room Temperature: These cookies are delicious chilled or at room temperature. The lemon curd will be slightly firmer when served cold and softer at room temperature.

Presentation Ideas for Lemon Thumbprint Cookies

• Powdered Sugar Dusting: Dust the cookies with powdered sugar for an elegant look before serving.

• Lemon Slices: Garnish the serving plate with thin slices of fresh lemon to highlight the lemon flavor in the cookies.

Lemon Thumbprint Cookies Recipe Tips

• Chill the Lemon Curd: Be sure to chill the lemon curd before spooning it into the cookies. This ensures that the curd is thick and won’t run out of the thumbprints.
• Make Ahead: You can make the lemon curd and cookie dough a day ahead of time and store them in the refrigerator until you’re ready to bake and assemble the cookies.
• Store Properly: Store the cookies in an airtight container in the refrigerator to keep the lemon curd fresh.
