Peanut Butter Chocolate Chip Bars

1 cup butter 
2 cups sugar
1/2 cup peanut butter
2 eggs
1 tsp vanilla
2 1/2 cups flour
1 tsp baking powder
1/4 tsp baking soda
1/2 cup or more semi-sweet chocolate chips

Melt butter and brown sugar together in pot on stove top stirring until melted.  Turn off heat and add peanut butter.  Stir until smooth and allow to cool.

Combine flour, baking powder, and baking soda in large bowl and set aside.

Add eggs to the butter and sugar mixture stirring well to blend.  Add vanilla and stir well.  Add flour mixture to butter and sugar mixture stirring until well combined.  Stir in chocolate chips (leaving some for sprinkling on top of batter).  

Spoon batter into a 9X13″ greased pan.  Using an offset spatula spread batter to edges of pan.  Sprinkle with remaining chocolate chips and bake at 350 degrees for 20-25 minutes.  Allow to cool before cutting into squares.  I cut my pan 4 rows by 6 rows – this will give you 24 bars.
