Peanut Butter Chocolate Chip Cookies

I have a serious love of peanut butter.  I printed out this recipe from all recipes awhile ago and had a friend leave a few jars of peanut butter behind when he moved out of state I decided to try them out.  The end result was delicious chewy peanut buttery chocolatey goodness.  They were quite the hit at work and gone within the first 2 hours of my shift.  Hope you like them!

Peanut Butter Cookies from Heaven (Makes 3 dozen cookies)
1 C butter
1 1/2 C packed light brown sugar
2 eggs

1 1/4 C cornstarch
3/4 tsp salt
1 tsp baking soda
1/2 tsp baking powder
1 C semi-sweet chocolate chips

Preheat oven to 350 degrees.  Cream together butter and brown sugar.  Beat in eggs, peanut butter, and vanilla.  Mix together flour, cornstarch, salt, baking soda, and baking powder.  Combine wet and dry ingredients. Stir in chocolate chips.  Roll 1 tsp sized balls, place onto ungreased cookie sheet (I lined mine with parchment paper), flatten slightly, and bake for 10 minutes.
