Ingredients

For the dough:

• 2 1/4 cups (281g) all-purpose flour, spooned and leveled
• 1 Tablespoon (8g) cornstarch
• 1/4 teaspoon salt
• 14 Tablespoons (200g) unsalted butter, softened
• 3/4 cup (150g) granulated sugar
• 1 Tablespoon fresh lemon zest
• 1 Tablespoon fresh lemon juice
• 1 large egg, room temperature
• 1 teaspoon vanilla bean paste or extract

For coating & filling:

• 1/2 cup (100g) granulated sugar
• 1/2 cup (140g) homemade or store-bought lemon curd

For the icing:

• 1 cup (120g) confectioners’ sugar
• 2 Tablespoons (30ml) fresh lemon juice

Step-by-Step Instructions

1. Mix the dry ingredients: In a medium bowl, whisk together flour, cornstarch, and salt. Set aside for 10 minutes to allow the flour to rest.
2. Cream the butter and sugar: In a large bowl, beat butter and 3/4 cup sugar on medium-high speed for 3 minutes, until light and fluffy. Add lemon zest, lemon juice, egg, and vanilla; beat on high for 1 minute. The mixture may appear curdled—this is normal and will smooth out during the next step.
3. Combine wet and dry ingredients: Gradually add the dry ingredients to the wet ingredients and mix on low speed until a soft dough forms. Chill for at least 3 hours, up to 3 days, for optimal texture.
4. Shape the cookies: Line baking sheets with parchment paper. Scoop 1 Tablespoon of dough and roll into balls. Roll each ball in granulated sugar and place 2 inches apart on the sheets.
5. Add the filling: Use your thumb to create a well in the center of each dough ball and fill with 1/2 teaspoon lemon curd.
6. Bake and ice: Preheat oven to 350°F (177°C). Chill the shaped cookies in the refrigerator (or on a baking sheet) for 15–20 minutes to prevent spreading. Bake for 12–13 minutes until edges are lightly golden. Cool on the sheet for 5 minutes, then transfer to a wire rack. Whisk confectioners’ sugar and lemon juice to make icing and drizzle over cooled cookies.

Tips & Variations

• Prevent over-spreading: Do not skip the chilling step; the dough will spread significantly at room temperature.
• Custom filling ideas: Substitute 1/2 cup chocolate ganache, crushed raspberries, or a mixture of cinnamon and sugar for a spiced version.
• Dietary adaptations: Use coconut flour for a gluten-free option (blend with almond flour for better structure) and dairy-free butter blend.
• Icing hacks: For a thicker glaze, add 1 teaspoon cornstarch to the confectioners’ sugar before mixing with lemon juice.

Serving Suggestions

Serve these cookies alongside iced tea, coffee, or as part of a brunch spread. For a festive touch, arrange them in a holiday-themed tin and pair with a literary favor (e.g., vintage recipe cards or pressed flowers). They also make an excellent topping for vanilla ice cream.

Storage & Reheating

Cool completely to avoid condensation. Store in an airtight container at room temperature for up to 1 week or refrigerate for 10–12 days. For a fresher texture, reheat at 250°F (120°C) for 3–5 minutes. Avoid freezing cookies with lemon curd filling, as the filling may become grainy.
