I have played around with chocolate chip cookie recipes for years and have finally came up with one that I love. The cookies are soft with plenty of flavor, but not soggy.
Preheat oven to 350 degrees.
Blend the butter, sugars, eggs, and vanilla until light and fluffy. In a separate bowl, combine the flour, baking powder, baking soda, and cream of tartar. Add the flour mixture alternately with the milk to the butter mixture. Fold in the chocolate chips and nuts. Drop by teaspoonfuls onto lightly greased cookie sheets.
Bake for 10 to 11 minutes or until barely light brown at edges.
