1/2 cup granulated sugar
1/2 cup packed light brown sugar
1/2 cup semisweet chocolate chips
1 large egg, beaten
1 teaspoon vanilla extract
1. Position two oven racks in the center of the oven and preheat the oven to 350°F.
2. Combine all the ingredients in a bowl, and stir with a wooden spoon until smooth.
3. Divide the dough into 24 portions, about 1 heaping tablespoon each. Roll each portion between your hands to form a smooth ball. Place the balls of dough on ungreased cookie sheets, spacing them 1 inch apart. You should get about 12 cookies per sheet. Using a fork, press on the dough in two directions to form a crosshatch pattern.
4. Bake for 10 minutes.
