Mix all the dry ingredients together in a bowl, then pour in the melted butter, vanilla and the egg.

Using a large spoon, mix until you have a sticky mass of cookie dough.

Roll into balls between one and one and a half inches around.

Bake in a 375°F oven for 10 minutes on a greased baking sheet.

The cookies should be a bit soft when you take them out of the oven but they will harden if you let them cool on the sheet for about five minutes before removing them to a wire tray.

Store in an airtight container or freeze.
