Step-by-Step Instructions

Making the Lemon Curd

The lemon curd is the heart of these cookies, offering that irresistible tangy flavor. Here’s how to get it just right:

Prepare the ingredients: Zest 4 large lemons and juice them. You’ll need about ¼ cup of lemon juice and 1 tablespoon of zest.
Combine the ingredients: In a small pot, whisk together ½ cup of granulated sugar, 4 egg yolks, lemon juice, and lemon zest.
Cook the curd: Cook the mixture over medium-low heat, stirring constantly for about 10-12 minutes. The curd will thicken as it cooks.
Check for thickness: The curd is ready when it coats the back of a spoon and leaves a trail when you swipe your finger across.
Add butter: Remove from heat and stir in 4 tablespoons of butter. Let the curd cool completely before using it in the cookies. (Pro Tip: Cool the curd in the fridge to speed up the process.)

Preparing the Cream Cheese Dough

Cream the butter and cream cheese: In a large bowl, beat together 7 tablespoons of softened butter and 4 ounces of cream cheese until smooth.
Add sugar: Gradually add 1 cup of granulated sugar and beat until light and fluffy.
Mix in the egg yolk: Add 1 egg yolk and 1 whole egg, then 1 teaspoon of vanilla extract. Mix until combined.
Fold in dry ingredients: In a separate bowl, whisk together 2 cups of all-purpose flour, 2 teaspoons of baking powder, and ¼ teaspoon of salt. Gradually fold the dry ingredients into the wet mixture until just combined.
Chill the dough: Cover the dough with plastic wrap and refrigerate for 1-2 hours. Chilling makes it easier to shape the dough and helps the cookies hold their shape during baking.

Assembling the Cookies

Scoop the dough: Use a standard cookie scoop (about 2 tablespoons) to portion the dough.
Roll in powdered sugar: Roll each dough ball in powdered sugar until fully coated.
Create a well: Use the back of a spoon or your thumb to press a well into the center of each cookie.
Fill with lemon curd: Spoon about 1 teaspoon of the cooled lemon curd into each well.
Bake: Preheat your oven to 350°F (175°C). Line baking trays with parchment paper and arrange the cookies 2 inches apart. Bake for 12-14 minutes, until the edges are lightly golden.
Cool and dust: Allow the cookies to cool on a wire rack. Once cool, dust with additional powdered sugar for that signature lemon bar look.

Expert Baking Tips

Use a kitchen scale: For the most accurate measurements, use a kitchen scale to weigh your ingredients. This ensures consistency and prevents dry or overly moist dough.
Chill the dough: Don’t skip the chilling step! Chilled dough is easier to work with and prevents the cookies from spreading too much during baking.
Avoid boiling the curd: When making the lemon curd, keep the heat low to avoid scrambling the eggs. Stir constantly for the smoothest, creamiest curd.
Make ahead: Both the lemon curd and the dough can be made ahead. Store the curd in the fridge for up to a week, and freeze the dough for up to 3 months.
Add a pinch of salt: A small pinch of salt in the lemon curd can help balance the tartness, enhancing the overall flavor.

Storage and Freezing

Storing Baked Cookies

Room temperature: Store the baked cookies in an airtight container at room temperature for up to 4 days.
Refrigeration: If you live in a warm climate, store the cookies in the fridge to keep the lemon curd fresh.

Freezing Instructions

Freezing unbaked dough: Place the assembled (but unbaked) cookies on a tray and freeze until solid. Then transfer them to an airtight container. Freeze for up to 3 months. When ready to bake, bake from frozen and add 1-2 extra minutes to the baking time.
Freezing baked cookies: Baked cookies can also be frozen for up to 2 months. Store them in a freezer-safe container with parchment paper between layers to prevent sticking.

FAQs

Can I use store-bought lemon curd?

Yes, if you’re short on time, store-bought lemon curd can be used. However, homemade lemon curd offers a fresher, more vibrant flavor.

How do I prevent the cookies from spreading too much?

Ensure the dough is well-chilled before baking, and avoid over-creaming the butter and sugar, as this can cause excessive spreading.

Can I make the dough ahead of time?

Absolutely! The dough can be refrigerated for up to 48 hours or frozen for several months.
