1 cup butter
1 1/2 cups white sugar
2 tsp vanilla extract
2 cups all-purpose flour
2/3 cup unsweetened cocoa powder
3/4 tsp baking soda
1/2 tsp salt
2 cups peanut butter chips (but I just add the whole bag!)
Preheat oven to 350°F. Grease cookie sheets.
In a medium bowl, cream together the butter and sugar. Stir in the eggs and vanilla. Combine the flour, cocoa, baking soda and salt, stir into the creamed mixture. Finally, fold in the peanut butter chips. Drop cookies by heaping teaspoonfuls onto the prepared cookie sheets. ( I like to use an ice cream scoop, they all come out uniform.)
Bake for 8 to 10 minutes in the preheated oven, until set. Cool on wire racks.
