I just made Lemon Curd Thumbprint Cookies so impossibly soft and lemony you’ll be mad you didn’t see this sooner.

Jump to Recipe

I am obsessed with these Lemon Curd Thumbprint Cookies. I swear they hit like a lemon bar but softer, chewy, unapologetic.

I love that the center is pure lemon curd, bright and punchy, and the dough gets this guilty-sweet edge from unsalted butter and kiss of lemon zest. Soft Baked Lemon Cookies can be tender and boring.

These are not. They crack slightly, they ooze a little, they make me stop whatever I’m doing.

And I will eat three in a row. No fuss, huge lemon hit, and I never want them to end.

Bring me more, please right now.

Ingredients

Print Recipe (No Advertisments)

Butter: gives rich tenderness and that buttery mouthfeel you want.
Sugar: adds sweetness and slight crunch in the finished bite.
Plus the extra sugar gives sparkle and a little crunch.
Egg yolk: adds richness and helps bind without drying things out.
Vanilla: warms the lemon and makes it taste homey.
Lemon zest: punches up fresh citrus, not fake lemon flavor.
Flour: the cookie’s backbone, keeps things tender and holding shape.
Salt: wakes up the sweetness and keeps flavors honest.
Basically baking powder gives a gentle lift and a lighter bite.
Lemon curd: bright gooey center, tart, sweet, and totally addictive.

Ingredient Quantities

1 cup (226 g) unsalted butter, softened

2/3 cup (135 g) granulated sugar, plus extra for rolling

1 large egg yolk

1 teaspoon vanilla extract

1 tablespoon lemon zest (from about 1 large lemon)

2 cups (250 g) all purpose flour

1/4 teaspoon salt

1/2 teaspoon baking powder

3/4 cup (240 g) lemon curd, for filling

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 350°F (175°C) and line two baking sheets with parchment paper or silicone mats.

2. In a large bowl, beat 1 cup (226 g) softened unsalted butter with 2/3 cup (135 g) granulated sugar until light and fluffy, about 2 to 3 minutes; scrape the sides once or twice.

3. Add 1 large egg yolk, 1 teaspoon vanilla extract, and 1 tablespoon lemon zest and mix until combined — don’t overmix or the cookies will get tough.

4. In a separate bowl whisk together 2 cups (250 g) all purpose flour, 1/4 teaspoon salt, and 1/2 teaspoon baking powder, then add the dry mix to the butter mixture and stir until just combined; the dough should be soft but not sticky.

5. Scoop tablespoon-sized portions of dough and roll into smooth balls; roll each ball in a little extra granulated sugar so they get a slight sparkle.

6. Place the dough balls about 2 inches apart on the prepared sheets, then press your thumb or the back of a small spoon into the center of each to make a 1/2 inch deep well; the indentation will puff a bit in the oven so press firmly.

7. Bake cookies for 10 to 12 minutes, until edges are set and bottoms are lightly golden; centers may still look slightly soft, that’s okay.

8. Let cookies cool on the baking sheet for 5 minutes so the wells set, then transfer to a wire rack to cool completely.

9. Once cool, fill each thumbprint with about 1 teaspoon of lemon curd (use the full 3/4 cup as needed), letting it sit until the curd firms slightly; store in an airtight container at room temperature for up to 3 days.

Equipment Needed

1. Oven (set to 350°F/175°C)
2. Two baking sheets lined with parchment paper or silicone mats
3. Large mixing bowl and a smaller bowl for the dry ingredients
4. Electric hand mixer or a sturdy wooden spoon (either works)
5. Measuring cups and spoons (for cups, grams and tsp/tbsp)
6. Microplane or box grater for the lemon zest
7. Cookie scoop or tablespoon and a small spoon for making wells
8. Wire cooling rack and a spatula to transfer cookies without breaking them

FAQ

What if my dough is too soft to make thumbprints? If it's sticky or too soft chill it in the fridge for 15 to 30 minutes. Cold dough is way easier to roll and hold the indent. If it's still soft, dust your hands with a little flour or chill the rolled balls on a baking sheet before pressing.

Can I use store bought lemon curd? Yes, absolutely. Store bought curd works great and saves time. If it's very runny, chill it first so it stays put in the cookie centers after baking.

How do I stop the curd from spreading during baking? Make the thumbprint deep enough, about 1/2 teaspoon worth of space. Also don't overfill the cavity and bake at the right temp. Let the cookies cool on the sheet a few minutes before moving them to a rack so the curd sets a bit.

Can I freeze these cookies or the dough? Yes. You can freeze unbaked dough balls on a tray, then transfer to a bag and bake from frozen with an extra minute or two. Baked cookies freeze well too; thaw at room temp or warm briefly in a low oven to freshen.

What if I only have whole eggs or no egg yolk? The yolk adds richness and tenderness. If you only have whole eggs use one whole egg but reduce moisture elsewhere by adding a tablespoon more flour if the dough feels too soft. Texture will be slightly different but still tasty.

Any tips for making the cookies prettier? Roll the dough evenly, press centers with the back of a small spoon or a marzipan tool for neat wells, and use a piping bag or small spoon to fill with curd. Sprinkle a tiny bit of zest or powdered sugar after they cool for a nicer finish.

Lemon Curd Thumbprint Cookies Recipe Substitutions and Variations

Unsalted butter (1 cup) → 1 cup (226 g) salted butter, but reduce added salt in recipe to 0 or just a pinch; or use 1 cup (226 g) cold coconut oil solid, works but cookies will be a bit firmer and have a light coconut hint.
2/3 cup granulated sugar → 2/3 cup light brown sugar for deeper flavor and chewier texture; or 2/3 cup coconut sugar for a lower-glycemic option, color will be darker and flavor more caramel-like.
1 large egg yolk → 2 tablespoons aquafaba (chickpea liquid) for binding if you need egg-free; or 3 tablespoons Greek yogurt for moisture and tenderness, but dough will be slightly denser.
3/4 cup lemon curd (filling) → 3/4 cup apricot jam or orange marmalade for a fruity swap; or use 3/4 cup mascarpone sweetened with a little powdered sugar and lemon zest for a creamy filling that wont run as much.

Pro Tips

1. Chill the dough for 15 to 30 minutes if it feels too soft, it firms up and is way easier to shape so your thumbprints keep their wells instead of flattening out in the oven.

2. Use a well-floured or slightly oiled spoon for pressing the wells, not your thumb if your hands are warm, your body heat will make the cookies spread too much.

3. Don’t overfill the centers, a teaspoon is plenty — too much lemon curd makes them runny and soggy the next day, plus they look messy.

4. Bake one test sheet first, ovens vary; if the edges brown too fast lower the rack or drop temp by 10 to 15 degrees and add a minute or two to the time.

5. Let the cookies cool on the pan for about 5 minutes so the wells set, then transfer to a rack to finish cooling; if you stack them while the curd is still soft they’ll stick together.
