Chewy Chocolate Peanut Butter Chip Cookies

I feel slightly ridiculous even typing this recipe up since it's on the package of the peanut butter chips that you have to get to make these cookies in the first place! But when I decided to compile my top 10 favorite cookies/bars, these had to be included. I usually make a half recipe so the amount of butter doesn't seem quite so obscene.

2 cups flour

3/4 cup cocoa

1 teaspoon baking soda

1/2 teaspoon salt

2+1/2 sticks butter, softened

2 cups sugar

2 eggs

2 teaspoons vanilla

1 10-oz package of peanut butter chips (Reese's if you must know--are there any other brands?)

Heat oven to 350 degrees. Cream butter and sugar together until fluffy. Add eggs and vanilla and mix well. Whisk together dry ingredients, except peanut butter chips. Add to the butter and sugar and stir/mix well. Stir in PB chips. Drop by rounded teaspoons on parchment paper-lined cookie sheets. Bake 8-9 minutes. (Do not overbake; cookies will be soft.) Cool slightly, then slide parchment onto wire racks. Cool completely.
