Preheat oven to 350°. Melt the chocolate chips with the water in a small microwave safe bowl on 50% power for one minute. Stir and repeat until chips are completely melted. Cream butter and sugar in a mixer or mixing bowl. Add eggs, salt and vanilla. Add melted chocolate and mix vigorously to combine. Mix remaining dry ingredients, (flour, cocoa powder, baking soda) and slowly incorporate into the wet ingredients until combined. Chill for an hour. Use a large cookie scoop to make evenly-sized cookies. Dough will spread, so only place six or so on a cookie sheet at a time. Push orange-colored peanut butter pieces (Reese's Pieces) into each cookie. Bake for 11 to 12 minutes or until tops are cracked and starting to set. Cookies will be soft, allow to cool completely before transferring to a platter for serving.
