How to make Mint Chocolate Thumbprint Cookies

Ingredients you’ll need:

  • dark chocolate
  • unsalted butter
  • caster/granulated sugar
  • large egg yolk
  • vanilla extract
  • peppermint extract
  • plain/all-purpose flour
  • cocoa powder
  • salt

For the mint filling, you’ll need:

  • white chocolate
  • heavy cream
  • peppermint extract
  • green food colouring (optional)

To make these thumbprint cookies, add the dark chocolate to a microwave-safe bowl, and heat in 30 second intervals, stirring after each one, until melted and smooth. Set aside.

In a separate bowl, beat the butter and sugar until light and fluffy. Add the egg yolk, vanilla, and mint extract, and mix until combined. Add the melted chocolate, and mix until combined.

Add the flour, cocoa powder, and salt, and mix to form a smooth, slightly sticky dough.

Roll the dough into tablespoon-sized balls (about 0.7oz each). Roll each one in granulated sugar, and place onto a baking tray lined with parchment paper or a silicone mat.

Use your thumb, or the back of a measuring spoon (I used a 1/2 teaspoon measuring spoon), to make an indent in the middle of each ball.

Bake for 10 – 12 minutes or until slightly firm, and cracked around the edges. If the indents have risen, you can gently press them back down with the measuring spoon. Allow to cool slightly before transferring them to a wire rack to cool completely.

For the filling, add the white chocolate and heavy cream to a microwave-safe bowl, and heat for 20 – 30 seconds. Stir until melted and smooth. Heat for longer if needed.

Once melted, stir in the mint extract, and a drop of green food colouring.

Fill the indents in the cookies with the mint chocolate filling, then place the cookies in the fridge for about 30 minutes to allow the filling to set. If desired, drizzle the cookies with even more melted chocolate.

NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements.

Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.

These mint chocolate thumbprint cookies look so delicious! Mint and chocolate is one of my favourite combos.

I made these last night to send to my mother-in-law for Mother's Day, as mint chocolate is one of her favorite combinations. My 9 year old daughter was able to help and the recipe came together quickly and easily. We really appreciated that you listed metric conversions as well, because ever since I got a kitchen scale, using measuring cups annoys me anymore. :) I've been spoiled.

Truly the only reason I gave this recipe 4 stars instead of 5 was because of the ganache filling, which I feel shouldn't be paired with a cookie. The taste and texture are great, but it makes for a very messy cookie. You can't stack them even after refrigerating them for quite some time, and if you tip them even a bit, the filling spills everywhere. Even after refrigerating them for a few hours, my daughter went to grab one after dinner and ended up getting ganache filling all over her hand and arm and clothes after absent-mindedly holding the cookie upright for too long while telling us about something that happened at school. Ganache on a cake works great because of the setup of the cake and using a fork rather than your fingers, but ganache for cookies makes for a very messy, sticky cookie. I also needed to overnight these to my MIL, and ended up having to spray saran wrap and wrap each individual cookie tightly knowing they wouldn't travel well (it was my fault for not reading the center was a ganache - I overlooked that portion and assumed the center would harden). I then packed the rest of the cookies to work for my coworkers, but when I took the Tupperware lid off to give them access, even though I was so careful travelling with the container of cookies, the ganache had spilled EVERYWHERE and stuck to the lid and the few cookies stacked on top were glued to the cookies below. Definitely not a cookie meant to travel outside the kitchen. The coworkers still loved them and stayed in the break room area so they could wash their hands after. Long story short, I will likely make these in the future but increase the amount of white chocolate and eliminate the cream from the filling altogether, so it's more of a hardened candy-type white chocolate center that only gets messy if kept out in the heat. Really delicious other than the mess factor, but I suppose some of the tastier things out there are a bit messy... :)

The cookie dough is excellent! Thank you! But I’m hesitant to try the white choc/mint ganache because chocolate and water don’t go well together, right? And most food coloring is water-based as is mint extract. Am I missing something?

Hi Anna, I used Sugarflair Holly Leaf - Sugartint Concentrated Droplet Colour for the white chocolate filling. You don't need much, and won't affect the chocolate. I also recommend Sugarflair's concentrated gel colours, too. For the extract, I used Nielsen-massey Pure Peppermint Extract :)

What exactly do you mean by "dark chocolate." Unsweetened?

Marsha

Dark chocolate is a form of chocolate containing a higher percentage of cocoa solids and cocoa butter than milk chocolate, and little to no sugar.

Is the cocoa powder the unsweetened kind? Like Hershey’s?

I use Dr. Oetker Fine Dark Cocoa Powder, but you can use Hershey's. :)
