These taste just like your favorite after dinner mint chocolate confectionery! Dark chocolate minty goodness in a cookie.
Make sure to use the best cocoa powder you can find, and if you can find Valrhona, use that. It’ll cost you a little more than the stuff you can find in the grocery store, but it is worth it.
Are these technically shortbread or sugar cookies?
They’re kind of both. It’s fine to call these either “decorated sugar cookies” or “decorated shortbread cookies.” But I’m going to refer to any of my cookie recipes that can used as a base for cookie decorating as “shortbread sugar cookies.”
- 2 parts flour to 1 part fat
- No eggs
- No leavening agent
- Dense and crispy
- 3 parts flour to 2 parts fat
- Contains eggs
- Contains a leavening agent
- Light and Chewy
All of my shortbread sugar cookie recipes don’t rise or spread, can be used for cookie decorating, have egg, but no leavening agent, and have a 2 ¼ parts flour to 1 part fat. Which makes them fall somewhere between a shortbread and a sugar cookie. They’re both shortbread and sugar cookies, and neither shortbread or sugar cookies, at the same time. They’re Shrodinger’s cookies!
All of my shortbread sugar cookie recipes can be used for slice-and-bake cookies as well!
If you would like more info on my preferred ingredient brands, tips and tricks, FAQs, and a little cookie science, I cover all of that in my No-Spread Lemon Shortbread Sugar Cookie Recipe.
Mint Chocolate Shortbread Sugar Cookies
- measuring spoons and cups
- mixing bowls
- cling wrap
- cookie cutters
- large knife
- Whisk dry ingredients (flour, cornstarch, and cocoa powder) together and set aside.
- Cream butter and sugars with paddle attachment, on medium-low speed, until fluffy and pale in color (about 5 minutes).
- Add egg and extract and mix on low speed until thoroughly combined. Scrape down the paddle with a spatula, and then continue to mix on low speed for another 30 seconds to ensure everything is fully incorporated.
- Add dry ingredients, all at once, and mix on low speed just until dough starts to come together and no dry bits remain. Do not overmix.
- Turn dough out onto cling wrap, tightly wrap, and refrigerate overnight (or for at least 4 hours).
- Knead, roll, cut out cookies, and return to fridge or freezer until firm. Leave a couple inches between cookies.
- Bake at 350°F for 15 minutes, rotate pan, and bake for another 1-5 minutes until edges are starting to turn golden brown.
- Remove from oven and allow to fully cool on cookie sheet before handling.
- Whenever you are baking with mint, be careful when you open the oven door, so you don’t get a face full of steamy mint extract! Probably not the aromatherapy experience you want.
- Chocolate cookies are a little harder to tell when the edges are darkening, so you can quickly and gently press on the center of a cookie, and if they feel firm, they’re done. If you leave a dent, or they feel squishy, let them bake for a little longer.
- The reason for adding 1-2 tablespoons of cornstarch to your dough is to prevent your cookies from shrinking or spreading during baking.
- If making slice-and-bake cookies, split dough in half, roll into logs, wrap tightly in cling wrap or parchment paper, and refrigerate before slicing and baking.
