If you’re looking for a unique but festive cookie to add to your Christmas cookie swap or holiday party, these are it! These chocolate mint thumbprint cookies are a little bit different but still perfect for the season.

They combine a super chocolaty thumbprint cookie (made with both melted dark chocolate and cocoa powder in the dough) with smooth and creamy peppermint white chocolate. These thumbprints are a delicious combo of flavors and textures, and I promise you’ll love them as much as we do!

Ingredients you’ll need

Here’s everything required to make these chocolate mint thumbprints (full recipe at the bottom of this article):

How to make chocolate mint thumbprint cookies

  1. Melt chocolate. You can use either a double boiler or microwave. Melt chocolate until just a few lumps remain, then stir until smooth.
  2. Prepare cookie dough. This recipe uses the creaming method and is really easy to make with the help of a stand mixer or hand-held electric mixer.
  3. Chill dough. Let the dough rest in the fridge for 30-60 minutes to firm up slightly so cookies will hold their shape.
  4. Roll dough balls in sugar and make a thumbprint. Roll into rounded tablespoons and roll each cookie dough ball in coarse or sanding sugar to coat. Place on a baking sheet pan and press a slight indent into each cookie.
  5. Bake. Bake at 350°F for about 12 minutes total, pressing down the center of the thumbprints about halfway through baking and again when they come out of the oven, just to push down any parts that puffed up.
  6. Make ganache. Heat cream till steaming, them pour over white chocolate. Let sit for a few minutes, then stir until smooth.
  7. Add ganache to thumbprints. Let ganache cool slightly to thicken, then spoon it into the center of each chocolatethumbprint cookie. Give the ganache filling at least 15 minutes before serving.

baking tip:Making thumbprint cookies

You can of course use your thumb, but I prefer the end of a wooden spoon or large dowel. It keeps your fingers clean and the indents uniform. Make a well in the cookie before placing them in the oven, again about 10 minutes in to press down any parts that may have puffed up, and once more when the cookies come out of the oven. Do this and you’ll have a perfect “thumbprint” every time.

More tips for this recipe

  • I recommend using higher quality chocolate chips or chopped bar chocolate for both the dark chocolate and white chocolate (make sure the white chocolate contains “cocoa butter” and not a substitute like “palm oil”).
  • When making the first indent into the cookie dough, only press about halfway down. Don’t press so far that the cookie ball cracks wide open, but a few small cracks are okay.
  • The white chocolate ganache will have an almost yellow tint when first melted, but as it thickens it will turn more opaque and white. If you want a thicker white ganache, let it cool for about 15 minutes, stirring often, before adding to the cookies.
  • These chocolate mint thumbprints would also be delicious filled with dark chocolate ganache instead of white. Follow the recipe, swapping chopped chocolate for the white.
  • If you want to add a final festive touch to these chocolate mint cookies, top ganache with some crushed candy cane pieces.
  • The chocolate cookies without ganache freeze very well. Store in a freezer bag for about a month. When ready to serve, let thaw at room temperature and add ganache filling.

Chocolate Mint Thumbprint Cookies

Servings: 24 cookies
Prep Time: 20 minutes
Cook Time: 15 minutes
Chill Time: 45 minutes
Total Time: 1 hour 20 minutes
Dark chocolate cookies with a puddle of peppermint flavored white chocolate ganache in the center. Perfect for the holidays, or any time of year.

Ingredients
 

For the chocolate cookies:

  • 4 ounces dark chocolate , chopped (110 grams)
  • 1 ½ cup all-purpose flour (190 grams)
  • ½ cup cocoa powder (40 grams)
  • ¾ teaspoon salt
  • 1 cup unsalted butter , at room temperature (226 grams)
  • cup granulated sugar (65 grams)
  • 2 tablespoons packed light or dark brown sugar
  • 2 large egg yolks
  • 1 teaspoon vanilla extract
  • ½ teaspoon peppermint extract
  • Coarse sugar , for rolling

For the filling:

  • 3 ounces white chocolate , chopped (85 grams)
  • 3 tablespoons heavy cream
  • ½ teaspoon peppermint extract

Instructions
 

To make the cookies:

  • In a double boiler or heat proof bowl set over a pan of simmering water, melt the chocolate. Stir until smooth, then remove from heat to cool slightly.
  • In a bowl, sift together the flour, cocoa powder, and salt. In the bowl of a stand mixer fitted with a paddle attachment, beat the butter and sugar and brown sugar together on medium high speed until light and fluffy. Add the egg yolks one at a time, mixing after each, followed by the vanilla and peppermint extracts.
  • Add the melted chocolate and mix until combined. Add the flour mixture all at once and mix until just combined. Form the dough into a disk and wrap in plastic wrap. Chill in the fridge for at least 30 minutes.
  • Preheat oven to 350°F. Line a sheet pan with parchment paper.
  • Roll the dough into rounded tablespoons and roll in the course sugar. Place on the prepared sheet pan and use your thumb or a dowel to create a well in the center of each cookie.
  • Bake for 10 minutes, then remove from the oven and reinforce indents with your thumb or dowel. Return to oven and bake for an additional 4-5 minutes, just until cracks begin to form in the cookies. Remove from oven and reinforce the indents again. Let cool completely on a cooling rack.

To make the filling:

  • In the microwave, heat the cream for about 30 seconds until boiling. Pour over the chocolate, let sit for 2 minutes, then stir until smooth. Stir in the peppermint extract.
  • Pour the filling into the cooled cookies. Let cookies firm up in the fridge for 15 minutes. Store cookies at room temperature in an airtight container for up to several days.

Notes

Note: For best results, use a good quality white chocolate that has cocoa butter listed in the ingredients.
