Blue Ribbon Chocolate Chip Cookies

2 sticks butter, room temperature
2 large eggs
1 c. packed brown sugar
1 c. white sugar
Mix till nice & creamy, then add:
1 Tablespoon vanilla
3/4 tsp. baking powder
3/4 tsp. baking soda
3/4 tsp. salt
3 to 3 1/4 c. flour

(I mix the baking powder, baking soda and salt with flour, then add slowly, one cup at a time. I also hand mix the last two cups of the flour as well as the chocolate chips and chopped walnuts.)

1 1/2 c. chocolate chips
1 c. chopped walnuts

Bake on good cookie sheets at 350 degrees for 11-12 minutes – just until sides get golden. Under cook rather than overcook, when in doubt.
