These cookies are sure to be a hit with all you chocolate lovers. The fresh mint flavor from the chocolate chunks helps to balance the richness of the cookie. These cookies can be easily modified to include peppermint extract if you need a little extra mint flavor.
In a large mixing bowl, use an electric hand mixer to cream the butter and sugars together until smooth and homogenous.
Once the butter, brown sugar, and granulated sugar are fully combined, add the eggs and vanilla. Continue to mix the ingredients on a medium-high speed until the eggs are fully incorporated into the cookie dough.
Add the flour, baking soda, and cocoa powder to the mixing bowl. Mix on low speed to incorporate the dry ingredients until no clumps remain.
Gently fold in the chopped chocolate until it is evenly distributed throughout the cookie dough.
Use a spoon or cookie scoop to form balls of cookie dough about 2 inches in diameter. Place the cookie dough on a baking sheet, leaving 2 inches between each cookie, and bake for 12 minutes.
Cool on the cookie sheet for about 5 minutes, then move to a wire rack to cool completely.
