Lemon Thumbprint Cookies
The cutest and easiest cookies you’ll ever make, lemon thumbprint cookies are one of my favorite ways to use lemon curd. These cookies are ready in under an hour, and the recipe makes approximately 60 (!) little cookies. You can use homemade microwave lemon curd or a jar of store-bought.
With no chilling time, this is a simple shortbread base with plenty of lemony filling. And if you love lemon, try my lemon poppy seed shortbread cookies, these 7-ingredient condensed milk lemon slices, or these classic lemon bars (they’re like sunshine in a dessert).
If you do decide to make homemade lemon curd (which takes less than 10 minutes to make), remember that it needs time to set in the fridge, so be sure to plan. You can also use other fruit curds like this orange curd or this spectacular spring rhubarb curd, marmalade, jam, or even American buttercream after the cookies have cooled.

Ingredients For Lemon Thumbprint Cookies
Ingredient Notes
- Powdered Sugar: Also called icing or confectioner’s sugar. Powdered sugar softens the protein in flour, leading to a more tender and delicate crumb in shortbread. This results in a melt-in-the-mouth texture.
- Cornstarch: Adding some starch makes the cookies lighter and gives a better overall texture.
- Butter: I use salted butter for all of my recipes.
- Sanding sugar (not pictured): This special sugar keeps its sparkle and shine even after baking. Although it is optional, I recommend it as it helps prevent the dough from sticking when you make the thumbprint indents.
- Lemon curd: Pictured is my super simple microwave lemon curd, but you can use any kind, even jarred.
It’s important to note that when making substitutions in recipes, the texture and flavor may be slightly different. However, these substitutes are the best options for changing the original recipe.
Ingredient Substitutions
- All-Purpose Flour: Cake & pastry flour is a good substitute for all-purpose.
- Cornstarch: You can substitute the cornstarch with rice, arrowroot, or tapioca flour.
- Butter: Margarine or shortening can be used instead of butter, but the cookies’ flavor and texture will probably change.
- Vanilla Extract: You can replace the vanilla with almond or lemon extract.
- Sanding sugar (not pictured): Use white granulated sugar if you don’t have sanding sugar.
- Lemon curd: Any fruit curd can be used in place of lemon. You can also use marmalade or jam.

How To Make Lemon Thumbprint Cookies
STEP 1: Whisk the flour, powdered sugar, and cornstarch in a mixing bowl.
STEP 2: In a second larger bowl, beat the butter and vanilla until pale and fluffy.
STEP 3: Add the flour mixture to the bowl.
STEP 4: Mix on low speed until a soft dough forms that clears the bowl.
STEP 5: Divide the dough into approximately 60 pieces, approximately 15 grams each. Roll all of the dough balls in sanding sugar.
STEP 6: Place the balls onto a lined baking sheet and make indentations with the back of a ½ teaspoon measuring spoon.
STEP 7: Fill each indent with lemon curd.
STEP 8: Bake the lemon curd cookies for 16 to 18 minutes or until the curd is set and the cookies are light gold on the bottoms.
Expert Tips
1. I use a scale to measure my cookie dough into 15-gram portions. You don’t have to do this, but it helps ensure the cookies are consistent in size and shape.
2. For an extra lemony kick, make a simple icing with powdered sugar and lemon juice to drizzle over the cookies once cool.
3. Using a measuring spoon is an excellent way to get perfect thumbprints, and a half teaspoon is just the right size for the ideal amount of lemon curd filling.
Recipe Notes
- You can make lemon thumbprints any size; however, the baking time will change.
- The dough for these cookies doesn’t spread very much, although it does spread slightly around the 10-minute baking mark. I bake all 60 lemon curd cookies on one sheet, and sometimes a couple will stick together, but not too badly. If you’re worried about them sticking together, bake 30 cookies per baking sheet.
- Rolling the cookie dough balls in sanding sugar is optional, but I recommend it as it prevents the ½ teaspoon from sticking when making the indents to fill.
- Depending on how small or large your cookie indents are, you may need a bit less or a bit more lemon curd than called for in the recipe.
Storage
- Cooled cookies can be stored in an airtight container on the counter for up to five days. They can also be stored sandwiched between parchment paper in a container in the freezer for up to one month.

- Divide the cookie dough into about 60 15-gram portions. Roll each piece between your hands to form a smooth ball. Place the sanding sugar in a bowl and roll the dough ball in sugar to coat. Place the balls on the parchment lined baking sheet(s).
- Use the back of a ½ teaspoon measuring spoon to press a round indent into the top of each ball. Don't push the measuring spoon to the cookie sheet, but close to it. You want a neat half-circle shape to fill with lemon curd.
- Spoon the lemon curd evenly between all of the cookies. Place the cookies in the oven and bake for 18 to 20 minutes or until the lemon curd is set and the bottoms are light gold. Transfer the cookies to a wire rack to cool before storing in an airtight container.
