Buttermilk Chocolate Cookies

I wanted something new, yummy and chocolate for this rather warm Sunday. As I was browsing, I came across these cookies and was intrigued that they used buttermilk, especially since I had some in my fridge I needed to use.  I found them on this website.  I modified mine and used Andes Mint pieces in half of the dough.  The chocolate mint were the favorite in our house, but both are fantastic!
They got rave reviews by all and my 7 year old said they were definitely "blog worthy"!  They are soft, gooey and totally chocolatey! YUM!

Buttermilk Chocolate Cookies
(about 2 1/2 dozen)

2 cups flour
1/2 t baking soda
1/2 t salt
1/2 cup butter
3/4 cup cocoa powder
2 cups sugar
1 t vanilla
1 egg
2/3 cup buttermilk
2 cups chocolate chips (Andes Mint pieces, white chocolate chip or semi-sweet chocolate chips)

Preheat oven to 350.  Line a baking sheet with parchment paper.  In a medium bowl, whisk together flour, baking soda and salt.   Melt the butter in a microwave safe bowl.  In a large bowl, combine melted butter (still warm) with the cocoa powder and whisk until very smooth.  Whisk in the buttermilk, egg, vanilla and the sugar.  Gradually stir in the flour mixture until no streaks of flour remain.  Add the chips you are using or divide the dough in half and do 2 different kinds! Drop by the spoonful onto prepared pan about 2 inches apart (these spread).  Bake for about 10 minutes, until the cookies are set on the edges.  The middle will be doughy but firm up as they cool.  Let them cool for a few minutes on the pan and then cool completely on a wire rack.
