Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

All-purpose flour (often combined with cornstarch for softness)
Granulated sugar (plus extra for rolling)
Unsalted butter, cold or room-temperature depending on method
Egg yolk(s) and/or whole egg
Lemon zest (and sometimes lemon juice)
Vanilla extract
Lemon curd (homemade or store-bought) for the filling
Optional: almond flour, powdered sugar, or additional flavorings like almond extract

Directions

Mix dry ingredients (flour, cornstarch if using, sugar, lemon zest) and cut in butter until the dough becomes crumbly.
Stir in egg yolk and vanilla until a soft dough forms. Chill if needed for easier shaping.
Roll into tablespoon-sized balls and optionally roll in granulated or powdered sugar.
Place on a parchment-lined baking sheet and press down the center of each with your thumb or the back of a teaspoon to create an indentation.
Bake until the edges just begin to turn golden (around 10–14 minutes at 350 °F).
While warm, fill each indent with lemon curd. Let cookies cool completely to set.

Servings and timing

Yield: Approximately 24–30 cookies, depending on size.
Prep time: 15–20 minutes (plus optional chilling).
Bake time: 10–14 minutes.
Total time: Around 30–45 minutes, including cooling.

Variations

Substitute lemon curd with other fruit jams or curds (e.g., raspberry or apricot).
Add almond flour for a richer, almond-scented crumb.
Drizzle melted white chocolate over cooled cookies for added sweetness.
For a savory twist, stir in finely chopped herbs like lemon-thyme into the dough.

Storage/Reheating

Storage: Store in an airtight container at room temperature for up to 5 days.
Freezing: Freeze cookies (without curd) in a sealed container; fill after thawing.
Reheating: Allow cookies to come to room temperature before serving for best texture.

FAQs

1. Can I skip chilling the dough?

Yes—some versions use cold butter and don’t require chilling, though chilling can help the dough hold shape better.

2. How do I make sure the lemon curd doesn’t ooze out?

Press a moderately deep indentation but not all the way through the cookie, and fill while the cookie is warm but stable.

3. Can I use store-bought lemon curd?

Absolutely—store-bought curd works well if you’re short on time.

4. What if the edges brown too quickly?

Lower the oven temperature slightly or remove the cookies when edges just begin to turn golden.

5. Can these be made gluten-free?

Yes—use a gluten-free flour blend in place of all-purpose flour.

6. Are they too sweet?

You can reduce the sugar in the dough slightly or use less curd to balance sweetness.

7. Can I make them nut-free?

Yes—omit almond flour and use only all-purpose flour.

8. What size cookie scoop is best?

A 1-tablespoon scoop makes perfectly sized cookies for filling.

9. How do I store leftover lemon curd?

Keep unused curd in a sealed jar in the refrigerator and use within a week.

10. Can I jazz them up for holidays?

Yes—top with citrus zest, edible flowers, or colored drizzle for festive flair.
