I've made this recipe a few times over the past couple of days so that I could play with the recipe and make sure that I was giving you the easiest instructions with the best outcome.
1/2 cup sour cream
3/4 cup peanut butter
1 3/4 cup dark brown sugar
1 tsp vanilla
2 cups flour
3/4 cup cocoa powder
1 tsp baking soda
1 tsp baking powder
1 tsp salt
1/2 cup each milk chocolate chips, semi sweet chocolate chips, and peanut butter chips
After you've chilled the dough, shape into balls using a heaping tablespoonful of dough. Place on greased baking sheet. Using nonstick spray, grease the bottom of a glass and press the dough balls into a patty shape on the baking sheet. Your dough should be about 2" in diameter and roughly 1/2" inch thick.
Bake cookies in a 350 degree oven for 10 minutes. Remove from oven and allow to cool on the baking sheet for 1-2 minutes. Remove from cookie sheet and finish cooling on a wire rack. You should get about 4 dozen cookies from this recipe.
Update: Also, I've linked up this cookie recipe at Simply Sweet Home, Rattlebridge Farm and Be Different, act Normal. So help me show them my thanks and head on over there to see all the good stuff they have posted.
