Preheat the oven to 350° and line a large baking sheet with parchment paper. (or two baking sheets) in a large bowl add the butter and sugar and beat using a hand mixer until the mixture becomes smooth and creamy.

Add the vanilla and egg and beat until combined.

Add in the flour, cocoa powder, baking soda and salt to the bowl and beat again until everything becomes mixed together and a dough forms.

Make sure to scrape down the walls with a spoon to get all the dry ingredients mixed together.

Roll into 1 tbsp sized balls and place them on the baking sheet.

About 1-2 inches apart.

Bake for 10 minutes.

Let cool for 20 minutes after removing them from the oven.

While they are cooking make the frosting.

In a large bowl add the butter, powdered sugar, milk, peppermint extract and food coloring and beat using the hand mixer.

Add however many drops of food coloring to get your desired color.

Spread over the tops of the cookies with a knife and place in the freezer for 20 minutes or over night.

Before you take the cookies out begin melting the chocolate.

In a small microwaveable bowl add the chocolate chips and oil and microwave and stir every 30 seconds until everything is melted.

Add the melted chocolate into a small zip lock bag and close, snip off a small piece of the corner of the bag and drizzle the cookies with the chocolate.

The chocolate will harden since the cookies are cold just let them sit for a few minutes.

Serve or thaw then serve and enjoy!
