In a large bowl, beat the butter and sugars on high speed for 3-5 minutes, occasionally scraping down the sides of the bowl.

Step 3

Add eggs and vanilla and beat for 1 minute more.

Step 4

Mix in flours, baking soda and salt. Stir in chocolate chips.

Step 5

Bake for about 10 minutes, or until cookies are just golden. Do not over bake. Let sit on cookie sheet for ten minutes before removing to a wire rack to cool completely.
