Heat the oven to 350ยบ ... line a few baking sheets with parchment.
Have a bowl of mini marshmallows ready, approx. 3-4 cups - you'll be QUICKLY pressing them into par-baked cookies and returning them to bake longer.
In a large mixing bowl, combine:
1 cup soft butter
1-1/2 cups sugar
2 eggs
2 tsp. vanilla extract
2/3 cup cocoa powder
1/8 tsp. salt
1 tsp. baking soda
2=3/4 cups flour
Blend well. Stir in 2 cups semisweet chocolate chips.
Drop by rounded (heaping) tsps. onto parchment, leaving an inch between each cookie (12-15 per pan).
Bake for 8 MINUTES - remove from oven and VERY QUICKLY place a few mini marshmallows on top of each cookie and gently press into dough (NOT hard - don't press them down to the bottom of the pan!!)... return cookies to the oven and bake for an additional 2 minutes. Remove from oven. While still warm, gently dust the marshmallows with cocoa powder (I used a small strainer to tap the cocoa powder onto them). Cool completely before removing from parchment.
