How do thumbprint cookies keep their shape?

Other than taste and texture, the most important part of a thumbprint cookie is, well, that it has a thumbprint-sized indentation in the center. If you’ve ever made thumbprint cookies, you may have noticed that they have a tendency to crack—and that the indentation has a tendency to heal up.

Over the years, I’ve tried all kinds of tricks to get them to keep their shape. I even placed a few round ceramic pie weights in the center of each cookie as it baked. That was truly ridiculous of me—even though it worked.

I’ve made so many thumbprint cookies that I feel confident I’ve made all the mistakes in the world. I’m back from the edge, and I’ve got guidelines. If you want a cookie that is still soft and tender but keeps its shape, here are the rules to follow.

First, mind the temperature. Make sure all of your ingredients are at room temperature when making the dough, then shape the dough completely while it’s soft. After the dough is shaped, chill it briefly before baking.

Second, use a 1/2-teaspoon measuring spoon to make the impression—not your thumb. I’m sure you have lovely thumbs, but the tips are attached to the rest of your thumb. And they’re not quite round.

Third, press the bowl of the measuring spoon back into the center immediately after the cookies come out of the oven. It won’t disturb the shape of the rest of the cookie, and it will ensure that you have a proper indentation for your filling.

Since these are chocolate, you’ll have to judge whether they’re done or not by their texture, not a slight browning around the edges or anything. They go from glossy (raw) to matte (baked).

What’s in that filling?

Chocolate thumbprint cookies are some of the most versatile cookies you can make (we have a recipe for plain vanilla jam thumbprints, too) since you can fill them with whatever you like. Melted chocolate, softened caramel, seedless jam, or even frosting are all legitimate fillings.

When I first made these cookies, I made them super fancy with a homemade soft caramel filling, chopped nuts, and a chocolate drizzle. They were quite beautiful and classed up my holiday cookie boxes. 🎄🎁But that was a little extra (apologies to my children, who don’t bother to read this blog anyway).

Caramel filling

The recipe for caramel filling that I included in the original recipe is still included below. It really does make quite a lovely fancy chocolate thumbprint. You can also make a soft caramel filling in the microwave, which is much easier. Just follow these caramel recipe instructions.

White chocolate filling

I’m much more likely to fill these simple cookies with a simple filling. I love using melted white chocolate chips. You don’t have to add a thing and they won’t harden completely even after they set. Sprinkle them with some nonpareils before they dry for a festive touch.

Chocolate filling

To make a lovely chocolate filling, just place 4 ounces of chopped chocolate (or chocolate chips) and 2 tablespoons (28 g) virgin coconut oil in a small, heat-safe bowl. Place the bowl over a small pot of simmering water, taking care to ensure that the bowl does not touch the water.

Heat, stirring occasionally until the mixture is melted and smooth. Remove the chocolate mixture from the heat and allow it to cool for about 5 minutes or until it just begins to thicken. Pour the filling into the wells of the cooled cookies and allow to sit at room temperature until set (about 45 minutes).

Ingredients and substitutions

Dairy-free: I would try using a mix of half melted and cooled shortening/half room temperature Earth Balance buttery sticks in place of the butter, and full-fat coconut milk for the cream in the caramel filling.

Egg-free: Since it’s only one egg, I would recommend using one “chia egg” (1 tablespoon chia flour + 1 tablespoon lukewarm water, mixed and allowed to gel) as that is the most neutral-flavored egg replacement that actually adds structure instead of just moisture (applesauce only adds moisture, and eggs provide much more than moisture).

Nut-free: Easy! Just sprinkle with something other than nuts.
