Marc's Chocolate Chip Cookies

Preheat oven to 350 degrees F. Cream together the butter and sugar. Add egg and vanilla. In a separate bowl, sift the flour and baking soda. Add them slowly to the mixture. Fold in chocolate chips gently so they're not broken. Spoon cookie dough about a teaspoon at a time onto a baking sheet and bake for about 10 minutes, or until golden brown.
