This recipe has two main components: the buttery cookie base and the luscious lemon curd filling. You can use store-bought lemon curd for convenience, but homemade curd is truly special.
For the Cookie Dough
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted butter | 1 cup (2 sticks), softened | |
| Powdered sugar | ¾ cup (95 g) | |
| Vanilla extract | 1 teaspoon | |
| All-purpose flour | 2 cups (250 g) | |
| Cornstarch | ¼ cup (30 g) | For a tender, crumbly texture |
| Salt | ½ teaspoon |
For the Lemon Curd Filling
| Ingredient | Amount | Notes |
|---|---|---|
| Lemons | 2-3 large | Zest and juice needed |
| Granulated sugar | ¾ cup (150 g) | |
| Eggs | 2 large | |
| Egg yolk | 1 large | For extra richness |
| Unsalted butter | 4 tablespoons (½ stick), cold | Cut into small pieces |
Step-by-Step Instructions
1. Make the Cookie Dough
In a large bowl, cream together the softened butter and powdered sugar until light and fluffy. Beat in the vanilla extract. In a separate bowl, whisk together the flour, cornstarch, and salt. Gradually add the dry ingredients to the butter mixture, mixing until a soft dough forms. Divide the dough in half, shape each half into a disk, wrap in plastic wrap, and refrigerate for at least 1 hour, or until firm.
2. Roll and Cut the Cookies
Preheat your oven to 350°F (175°C) . Line two baking sheets with parchment paper.
On a lightly floured surface, roll out one disk of dough to about ¼-inch thickness. Using a 2-inch round cookie cutter, cut out an even number of cookies. Place them on the prepared baking sheets, about 1 inch apart. Use a small teaspoon or piping bag to create a small indentation in the center of half of the cookies. This will help hold the lemon curd.
3. Bake the Cookies
Bake for 10-12 minutes, or until the edges are just golden. The cookies will be soft but will firm up as they cool. Let them cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
4. Make the Lemon Curd (or Use Store-Bought)
If making your own, whisk together the lemon zest, lemon juice, sugar, eggs, and egg yolk in a small saucepan. Cook over medium-low heat, stirring constantly, until the mixture thickens and coats the back of a spoon (about 5-7 minutes). Remove from heat and whisk in the cold butter until smooth. Let the curd cool completely.
5. Assemble the Cookies
Once the cookies are completely cool, spoon a small amount of lemon curd into the indentation of the cookies you set aside. Top each with one of the plain cookies to create a sandwich, or simply leave them open-faced. Dust with powdered sugar before serving.
Pro Tips for Perfect Lemon Curd Cookies
Chill the Dough Thoroughly: Chilling the dough prevents the cookies from spreading too much in the oven, helping them keep their shape.
Don't Overfill: A little lemon curd goes a long way. About 1 teaspoon per cookie is usually perfect.
Let the Curd Cool Completely: Warm curd will melt the cookies and make a mess. Be sure it's completely set before assembling.
Use Fresh Lemons: Fresh lemon juice and zest give the cookies that bright, vibrant flavor that you just can't get from bottled juice.
Variations to Try
| Variation | What to Add/Change |
|---|---|
| Raspberry Lemon Curd | Swirl in a small amount of raspberry puree into the curd. |
| Lemon and Thyme | Add ½ teaspoon of fresh thyme leaves to the cookie dough for a subtle herbal note. |
| Coconut Lemon Cookies | Add ½ cup of shredded coconut to the cookie dough. |
| Gluten-Free | Use a high-quality 1:1 gluten-free flour blend. |
Storage
Store these cookies in an airtight container in the refrigerator for up to 5 days. You can also freeze the unfilled cookie bases for up to 2 months and fill them with fresh curd when ready to serve.
A Gentle Reminder
These Lemon Curd Cookies are a beautiful example of how a few simple ingredients can come together to create something truly special. They're a little bit buttery, a little bit tart, and completely irresistible. I hope they bring a little sunshine to your day.
