1/3 cup melted butter.
1 teaspoon baking soda.
Pinch of salt.
3/4 cup sugar (1/2 cup if you would like it less sweet, 1 cup if more sweet) we both know which you're choosing though.
1 large egg.
1 teaspoon vanilla extract.
1 1/2 cups of all-purpose flour.
I don't understand basic directions so you'll have to work it out for yourself.
