Easy Lemon Thumbprint Cookies Recipe with Curd and Icing Drizzle
These lemon thumbprint cookies are a buttery, lemon-zest shortbread filled with bright lemon curd and finished with a simple icing drizzle. They take about 60 minutes start to finish including two chills, make 20 cookies, and the double chill is what keeps the wells from spreading shut in the oven.
Lemon desserts have a way of feeling like sunshine even in the middle of winter, and these cookies lean all the way into that. The dough gets a hit of fresh zest right at the creaming stage, then the shaped cookies chill twice, once before baking and once after indenting, which is the part that keeps the wells deep and clean instead of puffing closed.
The chilling steps are where people get impatient and skip ahead, so I’ll explain exactly why each one matters.
If your icing looks too thin to hold a line when you drizzle it, that’s an easy fix before it ever touches the cookies.

- 1 3/4 cups (220g) all-purpose flour, spooned and leveled

Ingredient Notes and Substitutions
Lemon zest: Zest the lemon before you juice it, and use only the yellow part — the white pith underneath turns the dough bitter. Two medium lemons usually gets you both the zest and juice this recipe needs.
Cornstarch: The cornstarch alongside the flour is what gives this shortbread its tender, almost powdery bite. Skipping it isn’t a disaster, but the cookies bake up a little tougher without it.
Step-by-Step Instructions
Step 1: Cream the Butter, Sugar, and Zest
Beat the softened butter, sugar, and lemon zest together until pale and fluffy, about 2 to 3 minutes. The zest releases its oil into the butter as you beat, which is where most of the lemon flavor actually comes from, so don’t shortcut this step.
Step 2: Add the Egg, Lemon Juice, and Vanilla
Beat in the egg, lemon juice, and vanilla extract until combined. The mixture will look slightly loose or glossy at this stage, which is normal; it tightens back up once the dry ingredients go in.
Step 3: Mix in the Dry Ingredients
Whisk the flour, cornstarch, and salt together, then add it to the wet mixture on low speed just until combined, with a few flour streaks still visible is fine. Overmixing here is what makes a shortbread like this bake up tough instead of short and tender.
Step 4: Chill the Dough
Cover the bowl and chill the dough for 20 to 30 minutes. This first chill firms the butter back up after creaming, which keeps the dough from being too soft to roll cleanly in the next step.
Step 5: Roll and Indent
Scoop the chilled dough into 1-tablespoon balls and roll smooth. Press a deep well into the center of each one with your thumb or a rounded teaspoon — if the edges crack a little, that’s normal for this dough, just pinch them closed.
Step 6: Chill Again, Then Bake
Place the shaped cookies on a lined baking sheet and chill for another 15 minutes; this second chill is what actually keeps the wells from puffing shut in the oven, skipping it is the most common reason this cookie loses its shape. Preheat your oven to 350°F (175°C) and bake for 11 to 13 minutes, until the edges are just barely golden.
Step 7: Fill with Curd and Drizzle Icing
Let the cookies cool completely on the pan, then spoon about 1/2 teaspoon of lemon curd into each well. Whisk the powdered sugar with water, a little at a time, until the icing drips off a spoon in a thin ribbon rather than running right off — if it looks too thin to hold a line, add a touch more powdered sugar. Drizzle over the filled cookies and let set for about 10 minutes before serving.

A Bright Citrus Cookie for Any Tray
Once you’ve chilled the dough twice, the rest is simple — it’s really just bake, fill, drizzle, and let it set. These stand out next to all the chocolate and caramel cookies on a holiday plate.
These keep well in the fridge for up to five days since the curd stays freshest that way, or freeze the shaped, unfilled dough balls and bake a smaller batch whenever you want them fresh.
