Lemon Curd Cookies Ingredients
Here's a simple look at what goes into making these Lemon Curd Cookies.
See Recipe Card Below This Post For Ingredient Quantities
For the Lemon Curd
- Lemon juice: Freshly squeezed lemon juice gives the curd its bright, tangy flavor. Bottled juice won't taste as fresh or vibrant.
- Lemon zest: The zest adds extra lemon oils and aroma that make the curd even more fragrant and flavorful.
- Egg yolks: These thicken the curd and give it that silky, smooth texture. Save the whites for meringues or an omelet.
- Granulated white sugar: Sweetens the curd and balances out the tartness of the lemon juice.
- Salt: Just a pinch enhances the lemon flavor and keeps the curd from tasting flat.
- Unsalted butter: Cold, cubed butter is whisked in at the end to make the curd rich and glossy. It also helps it set as it cools.
For the Lemon Sugar Cookies
- All-purpose flour: Forms the base of the cookie dough and gives the cookies their soft, tender structure. Spoon and level for the best results.
- Baking powder: Helps the cookies rise just a little and keeps them from being too dense.
- Sea salt: Balances the sweetness and brings out the buttery, lemony flavors.
- Unsalted butter: Softened butter creamed with sugar creates a light, fluffy dough that bakes up tender.
- Granulated white sugar: Sweetens the dough and, when rubbed with lemon zest, releases even more citrus flavor.
- Egg: Binds the dough together and adds moisture for a soft cookie texture.
- Vanilla: A little vanilla enhances the overall flavor without overpowering the lemon.
- Lemon zest: Rubbed into the sugar, it infuses the dough with bright lemon flavor in every bite.
- Powdered sugar: Dusted over the baked cookies for a touch of sweetness and a pretty, snowy finish.
How to Make Lemon Curd Cookies
Making these Lemon Curd Cookies is easier than it looks, and the homemade lemon curd is totally worth it.
Make the lemon curd: Add lemon juice, lemon zest, egg yolks, granulated sugar, and salt to a small saucepan and whisk everything together. Heat the mixture over medium-low heat for 20 to 25 minutes, stirring frequently, until it thickens and coats the back of a spoon. You'll know it's ready when you can draw a line through the curd on the spoon and it stays put.
Finish the curd: Remove the pan from heat and slowly whisk in the cold, cubed butter until it's completely melted and the curd looks smooth and glossy. Transfer it to a heatproof bowl, cover with plastic wrap pressed directly onto the surface to avoid a skin forming, and let it cool completely.
Mix the dry ingredients: In a small bowl, whisk together the flour, baking powder, and salt until evenly combined.
Infuse the sugar: In a large bowl, combine the sugar and lemon zest. Rub the zest into the sugar with your fingertips to release the lemon oils and make the sugar smell amazing.
Cream the butter and sugar: Add the softened butter to the lemon sugar and use an electric mixer on high speed to cream them together for 1 to 2 minutes until the mixture is light and fluffy.
Add the wet ingredients: Mix in the egg and vanilla on medium-high speed for 1 to 2 minutes until the dough turns pale and fluffy.
Combine: Add the dry ingredients and mix on low, then medium speed until just combined. Scrape down the sides of the bowl as needed to make sure everything is evenly mixed.
Shape the dough: Scoop the dough into 1 tablespoon portions and roll them into balls. Press each ball gently with a ½ teaspoon measuring spoon to create a little indent in the center.
Chill: Arrange the cookie dough balls on parchment paper-lined baking sheets and chill them in the fridge for 1 hour. This helps the cookies hold their shape and keeps the indents from puffing up too much.
Preheat: Preheat your oven to 350°F (175°C) while the dough finishes chilling.
Space the cookies: Once chilled, arrange the dough balls 12 at a time on a prepared baking sheet, leaving a little room between each one.
Bake: Bake the cookies for 8 to 9 minutes, just until the edges look set. The centers should still appear slightly soft.
Reshape if needed: After baking, use a small round cookie cutter to gently scoot the edges in a circular motion to help them return to their original round shape. If the indents puffed up, press the centers again with a ½ teaspoon to deepen them.
Cool: Let the cookies cool for 5 minutes on the baking sheet, then transfer them to a cooling rack to finish cooling completely.
Fill and serve: Once the cookies are fully cooled, sprinkle powdered sugar over the tops, then fill each indent with about 1 teaspoon of lemon curd. Enjoy!
Substitutions and Variations
Use store-bought lemon curd. If you're short on time, a good-quality store-bought lemon curd works just fine. Just make sure it's thick enough to hold its shape in the Lemon Curd Cookies.
Try lime or orange. Swap the lemon juice and zest for lime or orange to make lime curd cookies or orange curd cookies. The method stays the same.
Make them gluten-free. Use a 1-to-1 gluten-free baking flour in place of all-purpose flour. The texture will be slightly more delicate, but they'll still taste great.
Add almond extract. Replace half the vanilla with almond extract for a subtle nutty flavor that pairs beautifully with lemon.
Skip the powdered sugar. If you prefer less sweetness, leave off the powdered sugar dusting and just fill the Lemon Curd Cookies with curd.
Use a different filling. Try raspberry jam, blueberry compote, or even Strawberry Matcha Latte Cake filling for a fun twist.
Equipment For Lemon Curd Cookies
- Small saucepan: For making the lemon curd on the stovetop.
- Electric mixer or stand mixer: Creaming the butter and sugar by hand takes forever, so a mixer makes the job much easier.
- Parchment paper: Keeps the cookies from sticking and makes cleanup a breeze.
- Cookie scoop: A 1-tablespoon scoop helps you portion the dough evenly so all the cookies bake at the same rate.
- Cooling rack: Lets air circulate around the cookies so they cool evenly and don't get soggy on the bottom.
How to Store Lemon Curd Cookies
At room temperature: Store unfilled cookies in an airtight container at room temperature for up to 5 days. Fill them with curd just before serving.
In the fridge: Once filled with lemon curd, store the cookies in an airtight container in the fridge for up to 3 days. The curd needs to stay cold to keep its texture.
In the freezer: Freeze unfilled, baked cookies in a freezer-safe container for up to 3 months. Thaw at room temperature and fill with fresh curd before serving. You can also freeze the lemon curd separately for up to 3 months.
Serving Suggestions
These Lemon Curd Cookies are perfect on their own, but they're even better when paired with a few simple sides.
With tea or coffee: Serve them alongside a pot of Earl Grey or a hot cup of coffee for an afternoon treat that feels fancy but relaxed.
On a dessert platter: Arrange them next to White Chocolate Cupcakes or Cookie Dough Brownies for a colorful, crowd-pleasing dessert spread.
With fresh berries: A handful of fresh strawberries or blueberries on the side adds a pop of color and complements the lemon flavor beautifully.
As a gift: Pack them in a pretty tin or box and tie it with a ribbon. They make a thoughtful homemade gift that anyone would love to receive.
Top Tip
Use fresh lemon juice. Bottled juice won't give you the same bright, tangy flavor. Freshly squeezed lemons make all the difference in both the curd and the Lemon Curd Cookies.
Don't skip chilling the dough. That hour in the fridge helps the Lemon Curd Cookies keep their shape and prevents the indents from disappearing during baking.
Watch the baking time. These Lemon Curd Cookies bake fast. Pull them out when the edges are set but the centers still look a little underdone. They'll firm up as they cool.
Press the indents twice if needed. If the centers puff up during baking, gently press them down again with the back of a small spoon or measuring spoon while the cookies are still warm.
Make the curd ahead. You can make the lemon curd up to a week in advance and store it in the fridge. Just give it a stir before filling the Lemon Curd Cookies.
FAQ
Can you put lemon curd in cookies?
Yes, Lemon Curd Cookies works beautifully in cookies, especially thumbprint-style ones like these. Just make sure the curd is thick enough to hold its shape and add it after the cookies have cooled so it doesn't melt or run. My mom always says to make the indent deep enough so the curd has a cozy little well to sit in.
What do you do with lemon curd in baking?
Lemon curd can be used as a filling for cakes, cupcakes, tarts, and cookies, or swirled into cheesecake or pound cake batter. You can also spread it on scones, use it between cake layers, or dollop it on top of Bananas Foster Cheesecake for extra citrusy brightness. It's one of those fillings that makes everything taste a little more special.
What are common mistakes when making lemon curd?
The most common mistake is cooking it over high heat, which can cause the eggs to scramble. Keep the heat medium-low and stir constantly. Another mistake is not straining the curd if it gets lumpy, but if you cook it gently, you shouldn't need to. Also, don't skip covering it with plastic wrap directly on the surface, or you'll end up with a thick skin on top.
What is the secret to making cookies soft and chewy?
The secret is not overbaking them and using the right ratio of butter to flour. Pull cookies from the oven when the edges are set but the centers still look slightly underdone. They'll continue to firm up as they cool. Also, chilling the dough helps cookies hold their shape and stay tender. For these Lemon Curd Cookies, the extra chill time makes a big difference.
