Chocolate Chip Cookies

Who doesn't love a classic chocolate chip cookie?  We have made this recipe three times in the last month.

1 scant cup butter softened
3/4 cup sugar
1 tsp vanilla
1 egg yoke
2 cups flour
1 tsp baking powder
1/4 tsp salt
a couple handfuls of chocolate chips (I like to use milk chocolate)

Mix the butter and sugar with a mixer on medium speed, add in the egg yoke and vanilla until blended.  Mix in the dry ingredients with a spatula.  Add the chocolate chips.  Bake at 400 degrees for 11 minutes and let cool on the baking sheet slightly before moving to a wire rack.  Enjoy!
