These Dulce de leche cookies are buttery chocolate thumbprint cookies filled with luscious dulce de leche — either store-bought or homemade. This easy, no-chill recipe is ideal for the holidays or any time you want a quick, impressive treat.

This recipe uses a no-chill chocolate thumbprint dough and simple dulce de leche for the filling, so it comes together fast. The cookies are chocolatey, buttery, and gooey — a crowd-pleasing combination everyone will love.
The base for this recipe is adapted from my Chocolate Pistachio Thumbprint Cookies — the dough works beautifully with dulce de leche added to the centers for a rich finish.

Instructions
Follow these steps to make chocolate thumbprint cookies filled with dulce de leche. For exact quantities, refer to the recipe card below.
Step One: Combine dry ingredients. Whisk together the flour, salt, and sifted cocoa powder. Set aside.
Step Two: Cream butter and sugar. Beat the room-temperature butter until creamy, then add the granulated sugar and mix until combined. Add the vanilla extract and egg yolk, mixing just until incorporated. Scrape down the bowl as needed.
Step Three: Add dry ingredients. With the mixer on low, beat in the dry ingredients until just combined to avoid overmixing.
Step Four: Shape the dough. Roll dough into balls (about 1 tablespoon each). Place them on lined baking sheets. Press your thumb or the bottom of a small spherical teaspoon into each ball to create a shallow indentation for the filling.
Step Five: Bake. Bake at 350°F for 12–14 minutes. If the indentations lose shape while baking, press them gently again with a rounded teaspoon immediately after removing the cookies from the oven.
Step Six: Fill with dulce de leche. Spoon about 1/2 teaspoon of dulce de leche into each indentation. Finish with a pinch of flaky sea salt if desired. Let the cookies cool on the baking sheet for five minutes before transferring them to a wire rack to finish cooling.
Hint: Dip the teaspoon in flour before forming the thumbprints to prevent sticking.

Expert Tips
- Use a spherical measuring spoon: A 1/2 teaspoon spherical spoon creates a consistently shaped indentation.
- Lightly flour the spoon: Prevents the dough from sticking when you press the thumbprint.
- Don’t press too deep: Overly deep indentations can crack the cookie or cause the filling to leak. If cracks appear, gently press the dough back together.
