Ingredients
Dry Ingredients
- 2 1/4 cups all-purpose flour
- 1 Tablespoon cornstarch
- 1/4 teaspoon salt
Wet Ingredients
- 14 Tablespoons unsalted butter, softened
- 3/4 cup granulated sugar
- 1 Tablespoon fresh lemon zest
- 1 Tablespoon fresh lemon juice
- 1 large egg
- 1 teaspoon vanilla bean paste or vanilla extract
For Coating and Filling
- 1/2 cup granulated sugar for coating
- 1/2 cup lemon curd
Lemon Icing
- 1 cup confectioners’ sugar
- 2 Tablespoons fresh lemon juice
Instructions
- Mix Dry Ingredients: Whisk together the all-purpose flour, cornstarch, and salt in a medium bowl until evenly combined to create the dry base for the cookies.
- Cream Butter and Sugar: In a large mixing bowl, beat the softened unsalted butter and granulated sugar until the mixture becomes light, fluffy, and creamy. This ensures the cookies have a tender texture.
- Add Flavorings and Egg: Incorporate the fresh lemon zest, lemon juice, the large egg, and vanilla bean paste or vanilla extract into the creamed butter mixture. Mix until all ingredients are well blended.
- Combine Wet and Dry Ingredients: Gradually add the dry flour mixture into the wet ingredients, mixing gently until just combined to form a dough. Avoid overmixing to maintain a tender crumb. Once combined, cover and chill the dough for at least 3 hours; this firms up the dough making it easier to roll and helps develop flavor.
- Form and Coat Dough Balls: After chilling, roll the dough into 1-inch balls. Roll each ball in granulated sugar to coat completely. Place the coated dough balls on baking sheets lined with parchment paper or silicone mats, spaced about 2 inches apart to allow for spreading.
- Create Thumbprint Indentations and Fill: Gently press your thumb or the back of a spoon into the center of each dough ball to create a well. Fill each indentation with approximately 1/2 teaspoon of lemon curd, ensuring not to overfill to prevent spilling while baking.
- Bake the Cookies: Preheat the oven to 350°F (175°C). Bake the cookies on the middle rack for 12 to 13 minutes or until the edges just turn a light golden brown. This timing ensures a delicate texture without overbaking.
- Cool and Drizzle with Icing: Remove the cookies from the oven and let them cool completely on the baking sheet or a wire rack. While cooling, prepare the lemon icing by mixing confectioners’ sugar with fresh lemon juice until smooth. Drizzle the icing over the cooled cookies for a bright, tangy finish.
Notes
- Chilling the dough for at least 3 hours is essential for proper shaping and texture.
- Use fresh lemon juice and zest for the best vibrant lemon flavor.
- If lemon curd is not available, homemade or store-bought can be used.
- To make vanilla bean paste substitution easier, pure vanilla extract is an excellent alternative.
- Store cookies in an airtight container at room temperature for up to 5 days, or freeze for longer storage.
