• 2 tablespoons all-purpose flour (15g)
• 1 teaspoon cornstarch
• ¼ teaspoon baking powder
• ¼ teaspoon kosher salt
• 1 teaspoon lemon zest (from one small lemon)
• 1 large egg
• 2 tablespoons fresh lemon juice (30mL)

Cookie Dough

• 1 ¾ cups all-purpose flour (220g)
• 2 teaspoons baking powder
• ¼ teaspoon kosher salt
• ½ cup unsalted butter, room temperature (113g)
• 3 ounces cream cheese, room temperature (84g)
• ¾ cup granulated sugar (150g)
• ½ cup confectioners’ sugar (60g)
• 1 large egg, room temperature
• 1 large egg yolk, room temperature
• 1 teaspoon pure vanilla extract
• Confectioners’ sugar for dusting (optional)

Ingredient Substitutions

• Flour Alternatives – If you prefer a gluten-free version, you can use a 1:1 gluten-free baking flour blend.
• Dairy-Free Option – Substitute butter with dairy-free margarine and use plant-based cream cheese.
• Egg-Free Option – Replace the egg with a flax egg (1 tablespoon flaxseed meal + 3 tablespoons water, mixed and left to thicken for 5 minutes).

Step-by-Step Instructions

Step 1: Prepare the Lemon Curd

1. In a small saucepan, whisk together the granulated sugar, flour, cornstarch, baking powder, kosher salt, and lemon zest.
2. Add the egg and fresh lemon juice, whisking until the mixture is smooth.
3. Place the saucepan over medium-low heat and stir continuously for 2-3 minutes. The curd should thicken to a custard-like consistency and reach 190°F on a thermometer.
4. Remove from heat and pour the curd into a shallow, freezer-safe dish. Place in the freezer to cool while you prepare the cookie dough.

Step 2: Make the Cookie Dough

1. Preheat the oven to 350°F (175°C) and line two baking sheets with parchment paper.
2. In a medium bowl, whisk together the all-purpose flour, baking powder, and kosher salt. Set aside.
3. In a large mixing bowl, beat the room-temperature butter using a stand mixer or hand mixer on medium speed for 30-60 seconds until smooth.
4. Add the room-temperature cream cheese and continue beating for another 1 minute.
5. Scrape down the sides of the bowl, then add granulated sugar and confectioners’ sugar. Beat on medium speed until light and creamy, about 2 minutes.
6. Add the egg, egg yolk, and vanilla extract, then mix on medium speed until fully incorporated and fluffy, about 1 minute.
7. Gradually add half of the flour mixture and mix on low speed. Once incorporated, add the remaining flour and mix until just combined.

Step 3: Shape and Bake the Cookies

1. Scoop the cookie dough onto the prepared baking sheets using a tablespoon or small cookie scoop.
2. Using the back of a spoon, gently press an indentation into the center of each dough ball to create a well for the lemon curd.
3. Retrieve the chilled lemon curd from the freezer and spoon a small amount into the center of each cookie.
4. Bake for 10-12 minutes or until the cookies are lightly golden at the edges.
5. Allow cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack.

Step 4: Finishing Touches

• Once cooled, dust with confectioners’ sugar for an elegant finish.
• For an extra lemony touch, add a drizzle of lemon glaze (mix ½ cup confectioners’ sugar with 1-2 tablespoons of lemon juice).

Beginner Tips and Troubleshooting

Avoid Overmixing

Overmixing the dough can lead to dense cookies instead of a soft, cake-like texture. Mix until ingredients are just combined.

Preventing Sticky Dough

If the dough is too sticky, refrigerate it for 15-20 minutes before scooping.

Ensuring the Lemon Curd Sets

If the lemon curd is too runny, continue cooking for an additional 1-2 minutes while stirring constantly. The key is to let it thicken before using it as a filling.

Serving and Storage Suggestions

Best Ways to Serve

• Pair with a cup of hot tea or coffee for a cozy afternoon snack.
• Serve with a side of vanilla ice cream or fresh berries for a refreshing dessert.
• Add a dollop of whipped cream for extra indulgence.

Storage Tips

• Refrigeration – Store cookies in an airtight container in the refrigerator for up to 5 days.
• Freezing – You can freeze the baked cookies (without the powdered sugar dusting) for up to 3 months. Simply thaw at room temperature before serving.

Frequently Asked Questions

Can I Make These Ahead of Time?

Yes! You can prepare the cookie dough up to 48 hours in advance and refrigerate it. The lemon curd can also be made ahead and stored in the fridge.

Can I Use Store-Bought Lemon Curd?

Absolutely. If you’re short on time, store-bought lemon curd works just fine. Just ensure it has a thick consistency.

How Do I Know When the Cookies Are Done?

The edges should be lightly golden, and the centers should remain slightly soft. The cookies will continue to firm up as they cool.
