Sometimes when you’re craving a chocolate cookie, only a double chocolate cookie will do.

Take these Chocolate Thumbprint Cookies for example.

Not only are they fun to make, they have a melt-in-your-mouth texture with a soft middle and crispy edges.

In the middle I filled them with a fudgy chocolate ganache for a double dose of chocolate.

But if you’re not a fan of ganache, you can also use chocolate frosting.

The best part is you don’t have to wait for the dough to chill! Some thumbprint cookie recipes require refrigerating so they don’t spread too much while baking.

My recipe is balanced so they keep their shape without chilling. They do naturally spread a little, but they won’t be little pancakes.

For some extra crunch, I rolled them in pistachios I had leftover from making pistachio pudding so they were green for St. Patrick’s Day, but you can easily swap them out for rainbow sprinkles.

Why You’ll Love This Chocolate Thumbprint Cookie Recipe

  • Uses leftover egg yolk! – If you find yourself with an extra yolk after making my flourless chocolate cookies, now you can make thumbprints.
  • No chilling required! – My thumbprint cookies keep their shape after baking, so no need to wait for the dough to chill.
  • Decorate for all occasions! – Make them for any holiday by using seasonal sprinkles.

Ingredients For Chocolate Thumbprint Cookies

Here’s what you need to make your thumbprint cookies with chocolate:

  • Flour: Brings the dough together and provides structure
  • Cocoa powder: Gives them a deep, subtle chocolate flavor that balances the rich filling
  • Salt: Enhances the flavor in the dough
  • Butter: Contributes to the melt-in-your-mouth texture
  • Sugar: Sweetens the dough
  • Egg yolk: Using a whole egg adds too much moisture and gives the cookies a cakey texture. By using only the yolk, your cookies will have that tender, melt-in-your-mouth texture.
  • Vanilla: Really brings out the chocolate flavor
  • Pistachios or sprinkles: Gives the cookies an extra crunch on the edges
  • Baking chocolate: Semi-sweet is the best chocolate for ganache (which is usually between 40%-60% cacao), but you can also use bittersweet or white chocolate. Do not use milk chocolate as the chocolate flavor won’t be as pronounced.
  • Heavy cream: Needed for the fat content in your ganache filling so it sets up. Do not substitute milk or half and half.

What To Do With Leftover Egg Whites

Using only the yolk gives the cookies their desired soft and crispy texture, but it also gives you a leftover egg white. Here are some recipes using egg whites.

Chocolate Thumbprint Cookies

Yield: 12-14 cookies
Prep Time: 20 minutes
Cook Time: 10 minutes
Total Time: 30 minutes

These Chocolate Thumbprint Cookies with a rich and fudgy chocolate ganache filling are soft and tender with crispy edges and a melt-in-your-mouth texture. Dough does not require chilling so you can bake them right away!

Ingredients

  • 3/4 cup all purpose flour
  • 1/3 cup unsweetened cocoa powder
  • 1/4 teaspoon table salt
  • 1/2 cup (4 ounces or 8 tablespoons) unsalted butter, softened
  • 1/2 cup granulated sugar
  • 1 large egg yolk, room temperature
  • 1 teaspoon vanilla extract
  • 1/2 cup finely chopped pistachios or sprinkles
  • 1 ounce semisweet chocolate, chopped
  • 2 tablespoons heavy whipping cream

Instructions

  1. Preheat the oven to 350F. Line a cookie sheet with parchment paper (or lightly grease without paper).
  2. In a medium bowl, stir together the flour, cocoa powder, and salt.
  3. In a large mixing bowl on medium-high speed (with the paddle attachment if using a stand mixer), beat together the butter and sugar until creamy, about 1-2 minutes.
  4. Beat in the egg yolk and vanilla until incorporated.
  5. Turn the speed down to low then gradually beat in the flour mixture. It'll look crumbly but keep gently beating until a dough forms.
  6. Using a #60 cookie scoop or by hand, scoop into a 1 tablespoon ball, roll in pistachios/sprinkles, then place on cookie sheet 2 inches apart. Using your thumb, make an indent into the center of each cookie (don't flatten too much).
  7. Bake for 10-12 minutes or until the edges are firm. If necessary, use the back of a teaspoon to re-indent the cookies. Cool for 5 minutes before transferring to a cooling rack.
  8. Once completely cooled, make the ganache: Add chocolate to a heatproof bowl.
  9. In a small saucepan, heat the heavy cream until simmering but not boiling. Pour over the chocolate and wait 2-3 minutes or until the chocolate starts to soften. Slowly stir together until completely smooth.

    If the chocolate isn't fully melted, place the bowl over a pan of
    simmering water (do not let the bottom touch the water). Continue stirring until smooth. Do not get any water or steam in the bowl.
  10. Spoon ganache into the center of each thumbprint. Let the chocolate harden before serving.

    Store leftover cookies in an airtight container at room temperature for up to 1 week. Refrigerate if the ganache gets too warm.
