Sour Cream Chocolate Chip cookies

I grew up on these cookies. They're easily my favorite cookie, not only because they are cake like and moist, but because you have to chill the dough for an hour which offers ample dough snacking opportunities.

Old fashioned Sour Cream Chocolate Chip Cookies:
1 Cup Butter softened
2 eggs
1 1/2 Cups Sugar
3 Cups Flour
1 tsp Baking Powder
1/2 tsp baking soda
1/2 tsp salt
1 tsp vanilla
1 cup sour cream
1 12oz bag chocolate chips

Sift together flour, baking powder, baking soda and salt. Set aside.
In a large bowl beat together butter, sugar and eggs until light and fluffy.
At low speed beat in sour cream and vanilla until smooth.
Gradually beat in flour mixture until well combined.
Stir in chips.
Refrigerate one hour.
Preheat oven to 375F.
Lightly grease cookie sheets or use parchment. Drop batter by slightly rounded Tablespoonfuls, 2 inches apart.
Bake 10 to 12 minutes or until lightly golden brown. Cool on wire rack.
