These homemade thin mint cookies are so delicious. It is hard to beat a little chocolate wafer cookie dipped in chocolate.

Did you know that the best selling Girl Scout cookies are thin mints? I don’t doubt that statistic. They are definitely my favorite, well until I started making this homemade version. Of course it is hard to argue with homemade cookies. And I love cookies!

It is so easy to make these thin mint cookies too, with easy to find ingredients. If I can do it, you can do it. Let’s get baking!

Step 1: Gather the ingredients

Several ingredients in glass bowls on top of a wooden table, including chocolate, butter, sugar, cocoa powder, etc.

In order to make these amazing homemade thin mint cookies you will need the following ingredients:

  • Butter – Softened room temp, salted or unsalted.
  • White granulated sugar
  • Egg
  • Vanilla extract
  • Peppermint extract
  • Unsweetened cocoa powder
  • Baking powder
  • Salt
  • Chocolate – Candiquik, candy melts, chocolate chips, chocolate bars, etc.

Step 2: How to make thin mint cookies

Large glass bowl with creamed butter, sugar, egg, and vanilla extract

Begin by adding the softened room temperature butter to a large bowl. Mix the butter by itself for 3 to 5 minutes. Next, add the white granulated sugar and cream those together with a hand mixer or a stand mixer. You may also use a sturdy whisk.

Scrape the sides of the bowl with a spatula as needed. Next add in the egg, vanilla extract, and peppermint extract and blend those ingredients in.

Step 3: Dry ingredients

Thin mint cookies dry ingredients sifted together in a medium glass bowl.

In a separate bowl sift together the flour, cocoa powder, salt, and baking powder. Make sure to tap the sides of the sifter as you sift it. You may also whisk the ingredients together.

If you are left with any coco powder lumps, make sure to push those through breaking them up. This is the main reason why we sift the dry ingredients, to prevent lumps.

Step 4: Finish the thin mint cookies dough

Now mix the dry ingredients in about a third of it at a time until the cookie dough comes together. If you don’t have a mixer you will need to use a wooden spoon, a sturdy whisk will not work very well. Make sure to scrape the sides of the bowl as needed to get everything combined.

Now bring the dough together into a ball and cut it in half.

Next lay down a large sheet of parchment paper. Add one half of the dough and roll it out until it is between an eighth of an inch thick and a sixteenth of an inch. Honestly you can make them as thick as you want, but that is a good size.

Now take another piece of parchment paper and roll out the other half, then stack it on top of the first rolled out half. Place a final piece of parchment paper on top. Next, set the stack of rolled dough in the fridge and allow it to chill for at least an hour.

Step 5: Bake those thin mint cookies

Hand with green round cookie cutter cutting out round shapes.

Preheat the oven to 350 F/176 C.

Take one half of the rolled out chilled dough and place it on the work surface, keep the parchment paper underneath it. Use a small round cookie cutter, roughly 2 inches in diameter, and cut out several round cookies.

Place them on a sheet pan or cookie sheet lined with parchment paper or a silicone mat. Take all the dough scraps and combine them together, roll them out, and repeat.

Bake the thin mint cookies for 8 to 9 minutes. 8 minutes if you want them a little softer, and 9 minutes if you want them more crunchy.

Once the cookies are done baking, remove them from the oven and allow them to cool for a few minutes before placing them on a wire rack to cool completely.

Step 6: Dip those cookies in chocolate

Take a small microwave-safe bowl and melt your choice of chocolate. I really like using the Candiquik brand, because it melts really thin and sets quick and easy. But you can use whatever chocolate you want.

Use bursts of 25 seconds and then stirring, until completely melted. You may also use the double boiler method on the stovetop if you like.

Once melted, dip the cookies into the chocolate with a fork, then tap the fork to allow the excess chocolate to drip off. Place the dipped thin mint cookie onto a sheet pan lined with parchment paper or a silicone mat.

You can leave them plain if you like, or you drizzle a different color of chocolate on top, using a small plastic bag with the corner snipped off.

Once you are done dipping and decorating, place the cookies in the fridge to allow the chocolate to set. This will only take 20 to 30 minutes.

How long to homemade thin mint cookies last?

Not very long at my house. If you store them in an air tight container they will last a few weeks in the fridge. You may also freeze them for several months.
