Ingredients:
Creating the Luscious Lemon Curd Base
Our journey begin extracts with crafting a bright and tangy lemon curd that will be the heart of our cookie. This is where the vibrant lemon flavor truly shines.
1. In a medium saucepan, whisk together the 1/2 cup (100g) granulated sugar and the 3 large egg yolks. You want to ensure these are thoroughly combined before adding any heat.
2. Next, whisk in the 1 teaspoon of cornstarch. This acts as our thickening agent, ensuring a luscious curd. Don’t worry if it looks a little lumpy at this stage.
3. Add the 2 tablespoons of lemon zest and 1/4 cup (60ml) of fresh lemon juice to the saucepan. Stir everything together until it’s smooth. The zest will release its aromatic oils, infusing the curd with an incredible fragrance.
4. Place the saucepan over medium-low heat. This is crucial – we want to cook the curd gently to avoid scrambling the eggs. Stir constantly with a whisk, making sure to scrape the bottom and sides of the pan. You’ll notice the mixture gradually start to thicken.
5. Once the curd has thickened enough to coat the back of a spoon (this usually takes about 8-10 minutes), remove the saucepan from the heat.
6. Now, add the 1/4 cup (55g) of unsalted butter, sliced into tablespoons, to the hot curd. Whisk vigorously until the butter is completely melted and incorporated. The butter adds a beautiful richness and smooth texture to our curd.
7. Pour the lemon curd into a clean bowl and cover it directly with plastic wrap, pressing the wrap down onto the surface of the curd. This prevents a skin from forming. Let it cool completely at room temperature, then refrigerate for at least 2 hours, or until thoroughly chilled and set. A well-chilled curd will be easier to work with and will give your cookies that distinct lemon bar layer.
Whipping Up the Irresistible Butter Cookie Dough
While our lemon curd is chilling, we’ll prepare the buttery, tender cookie dough that forms the foundation of our creation.
1. In a large mixing bowl, or the bowl of your stand mixer fitted with the paddle attachment, cream together the 8 oz of room-temperature full-fat cream cheese and the 1/2 cup (110g) of room-temperature unsalted butter. Beat them on medium speed until they are light, fluffy, and well combined. Ensure your cream cheese and butter are truly at room temperature for the best creaming action; cold ingredients will result in a less smooth dough.
2. Gradually add the 1 1/2 cups (300g) of granulated sugar to the creamed mixture, beating until light and airy. This process can take a few minutes, but it’s essential for creating a tender cookie texture. Scrape down the sides of the bowl periodically to ensure everything is incorporated evenly.
3. Add the 1 large egg and 1 egg yolk, one at a time, beating well after each addition. This helps to emulsify the dough and create a cohesive texture.
4. Stir in the 1 teaspoon of vanilla extract and the optional 1/2 teaspoon of almond extract. The almond extract adds a subtle depth that complements the lemon beautifully, so I highly recommend it if you have it on hand.
5. In a separate medium bowl, whisk together the 2 1/4 cups (286g) of all-purpose flour, 2 teaspoons of baking powder, and 1/2 teaspoon of salt. Whisking these dry ingredients together helps to distribute the leavening agent and salt evenly throughout the flour.
6. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix the dough at this stage, as it can lead to tough cookies. Stop mixing as soon as you no longer see streaks of flour. The dough will be soft and slightly sticky.
Assembling and Baking Our Lemon Bar Butter Cookies
The final steps bring our delicious components together for baking.
1. Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper to prevent sticking and ensure even baking.
2. Divide the cookie dough in half. On a lightly floured surface, roll out one half of the dough into a rectangle that will fit the bottom of your chosen baking pan (an 8×8 or 9×9 inch pan works well). Gently press the dough into the bottom of the pan, ensuring an even layer. If the dough is too sticky, you can place it between two sheets of parchment paper and roll it out.
3. Remove the chilled lemon curd from the refrigerator and spread it evenly over the cookie dough base.
4. Roll out the second half of the cookie dough into another rectangle, slightly larger than the first. Carefully place this dough over the lemon curd, pressing down gently to seal the edges. You can also crimp the edges with a fork if you like.
5. Bake for 25-30 minutes, or until the edges are lightly golden brown and the top is set. The baking time will vary depending on your oven and the size of your pan.
6. Allow the baked cookie to cool completely in the pan on a wire rack before cutting into bars. This is a critical step, as the curd needs to set fully for clean cuts. Once completely cool, you can then cut them into desired bar shapes.

Frequently Asked Questions:
Can I make these cookies ahead of time?
Absolutely! These Lemon Bar Butter Cookies store beautifully. Once completely cooled, keep them in an airtight container at room temperature for up to 5 days. They might even taste better on the second day as the flavors meld!
What kind of lemons should I use?
Fresh lemons are key for the best flavor! Meyer lemons offer a slightly sweeter and more floral note, while regular Eureka or Lisbon lemons will give you a more intense citrusy tang. Whichever you choose, make sure to zest them first for maximum flavor, and then juice them for the recipe.
My cookies spread too much. What did I do wrong?
Several factors can contribute to cookie spread. Ensure your butter and sugar are properly creamed but not over-creamed. Also, chilling the dough is crucial – don’t skip this step! If your kitchen is warm, the dough might soften quickly, so working fast or chilling it again can help.
