Ingredients and Preparation

Before you begin, gather and measure your ingredients to keep the baking process smooth and mess-free.

For the cookie dough:

• 1 cup (226 g) unsalted butter, melted and slightly cooled
• 1 cup (200 g) granulated sugar
• ½ cup (60 g) powdered sugar
• Zest of 2 fresh lemons
• 1 large egg, room temperature
• 2 teaspoons pure vanilla extract
• 1 teaspoon fine sea salt
• ½ teaspoon baking soda
• 3 cups (390 g) all-purpose flour
• 2 tablespoons poppy seeds, for rolling

For the lemon curd (homemade version):

• 2 large eggs
• ½ cup (100 g) granulated sugar
• ¼ cup freshly squeezed lemon juice
• 1 tablespoon lemon zest
• 4 tablespoons unsalted butter, cubed

Optional ingredient substitutions:

• Use gluten-free flour blend (1:1 ratio) to make it gluten-free
• For dairy-free, use plant-based butter alternatives and dairy-free lemon curd

Preparation tip:
If you are making the lemon curd from scratch, prepare it ahead of time. It needs time to cool and firm up so it can be scooped or frozen into dollops before baking.

Step-by-Step Instructions

Step 1: Make the Lemon Curd

• In a small saucepan, whisk together eggs, sugar, lemon juice, and zest.
• Place the saucepan over low heat and stir constantly.
• Once the mixture begins to thicken (around 6–8 minutes), remove it from heat and stir in the butter until melted and smooth.
• Pour the curd into a bowl and let it cool completely. You can speed this up in the refrigerator.
• Once chilled, spoon small dollops (about 1 teaspoon each) onto a parchment-lined tray and freeze until solid—this will make them easier to stuff into the cookies.

Step 2: Prepare the Cookie Dough

• In a large bowl, whisk together melted butter, granulated sugar, and powdered sugar until smooth.
• Stir in lemon zest, egg, and vanilla extract. Mix until well incorporated.
• In a separate bowl, whisk together flour, baking soda, and salt.
• Gradually add the dry ingredients to the wet mixture, stirring gently until no streaks of flour remain.
• Cover the bowl with plastic wrap and chill the dough for at least 1 hour, or overnight if you want deeper flavor and firmer dough for handling.

Step 3: Assemble the Cookies

• Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
• Scoop out about 2 tablespoons of cookie dough. Flatten it in your palm and place a frozen lemon curd dollop in the center.
• Wrap the dough around the curd and seal the edges, rolling gently into a ball.
• Roll each dough ball in poppy seeds to coat the outer surface.
• Place the balls on the baking sheet, spaced about 2 inches apart.

Step 4: Bake

• Bake the cookies for 12–14 minutes, or until the edges are lightly golden but the centers remain soft.
• Remove from the oven and allow them to cool on the tray for 5–10 minutes before transferring to a wire rack.

Step 5: Storage

• These cookies can be stored in an airtight container at room temperature for up to 3 days.
• For longer storage, refrigerate them and bring to room temperature before serving.

Beginner Tips and Notes

If you’re new to baking or want extra guidance, here are some helpful tips:

• Don’t skip the chill time: Chilling the dough makes it easier to handle and prevents the cookies from spreading too much.
• Freeze the curd: If the lemon curd is not frozen or well-chilled, it may leak out of the cookies during baking.
• Use a cookie scoop: This ensures uniform cookies and makes stuffing easier.
• Avoid overmixing: Once the dry ingredients are added, mix just until combined to prevent a tough texture.
• Test your oven: Baking times may vary depending on your oven. If you’re unsure, bake a test cookie first to adjust time if necessary.

• With whipped cream: For a soft, creamy accent, dollop a bit of lightly sweetened whipped cream on top.
