Bringing up an old thread:
Here is the classic recipe for chocolate chip cookies in the US.
A cup is precisely 8 fluid ounces, which is a volume measurement. It equals about 240 ml. Use that volume whether you are measuring solids or liquids.
As a cheat, 1 cup of butter = 226 g butter (because it is less dense than water a cup of butter weighs less than a cup of water, and it's a real pain to measure out butter by volume.)
A teaspoon = 5 ml, a tablespoon = 15 ml.
You can substitute a package or two of vanilla sugar for the vanilla extract.
As a substitute for brown sugar in the recipe, add 2 tablespoons of molasses (from a Reformhaus, or use Grafschafter Zuckerrübensirup) to a cup of white sugar sugar. (In this recipe, you need 3/4 cup of brown sugar, so you'd use 3/4 cup of white sugar plus 1.5 tablespoons of molasses -- = 22.5 ml molasses)
