Ingredients
Here’s what you’ll need to bake about 8 large cookies (you can scale up if needed):
- ½ cup (1 stick) butter, softened
- ½ cup powdered sugar
- ⅓ cup granulated sugar
- 1 egg
- 1 egg yolk
- 1 tablespoon lemon juice
- 1 teaspoon lemon extract (or flavoring)
- ½ tablespoon lemon zest
- 2 cups all‑purpose flour
- ½ teaspoon baking powder
- ¼ teaspoon salt
- 1 tablespoon poppy seeds
- ½ cup lemon curd (homemade preferred; also usable store‑bought)
For the lemon poppy seed glaze:
- ¼ cup + 1 tablespoon powdered sugar
- 1 tablespoon lemon juice
- ½ teaspoon lemon zest
- 2 tablespoons butter
- ½ teaspoon poppy seeds
Instructions
- Prepare the lemon curd filling. Scoop out about 8 tablespoons of lemon curd; spread on parchment or plastic‑lined baking sheet to ~¼‑inch thickness, then freeze for 1‑2 hours or until solid.
- Preheat your oven to 350°F (≈180°C) and line a baking sheet with parchment paper.
- Cream together softened butter, granulated sugar, and powdered sugar until smooth and fluffy. Add in egg + egg yolk, lemon juice, lemon extract, and lemon zest. Mix until combined.
- Fold in the flour, salt, baking powder, and poppy seeds until no streaks of flour remain.
- Portion out the cookie dough (about ¼ cup dough per cookie). Flatten between your palms, place frozen lemon curd in center, then fold dough around it. Roll gently, flatten slightly to ~½‑inch thickness.
- Place cookies on prepared baking sheet. Bake for 12–13 minutes. They might look a bit underbaked—don’t worry; they will continue to set as they cool on the baking sheet.
- While cookies cool, make the glaze: Melt butter over medium heat, stir in lemon juice, powdered sugar, and lemon zest until just simmered. Remove from heat and stir in poppy seeds.
- When cookies are cooled (but still a bit warm is okay), brush glaze over them. Let set for a few minutes, then enjoy.

Baking Tips & FAQ
- Don’t judge them right when they come out. Because of the curd filling, the top might seem wet; cooling helps them firm up.
- Storing: Best kept in an airtight container in the fridge for up to 7 days. Warm slightly before eating (or microwave for a few seconds) if you prefer.
- Freezing: Freeze baked cookies (air‑tight container) for up to 2 months. Thaw in fridge or microwave briefly.
- Using store‑bought vs homemade curd: Homemade tends to freeze and hold better; some store‑bought curds may leak or not seal as well.
