Adapted from "Help! My Apartment Has a Kitchen Cookbook: 100+ Great Recipes with Foolproof Instructions" (Paperback) by Kevin Mills (Author), Nancy Mills (Author), Richard A.Goldberg (Illustrator)

2 sticks (1cup) butter, melted
1 cup brown sugar
1/2 cup white sugar
1 teaspoon vanilla
1 egg
1 teaspoon baking powder
1 teaspoon baking soda
1/4 teaspoon salt
2 1/4 cups all purpose flour chocolate chips to taste (1/2 cup to 1 1/2 cups depending on size)

Preheat oven to 350°F and grease 2 cookie trays.

Mix melted butter with sugars. Add in vanilla and egg. Mix in baking powder and baking soda and salt. Mix in flour 1/2 cup at time. Mix in chocolate chips. Form little balls (or big ones) and place them evenly spaced on your tray.  These will spread so not so close together.

Bake for about 10 minutes.  You can tell if they're done by the bottoms browning.  For softer cookies, don't wait until the tops get dark brown.
