Chocolate Crinkles

I've been making a lot of treats lately for school parties, family parties, holiday junk, etc.  Here is another classic family favorite.

Mix together:
1 cup unsweetened cocoa powder
2 cups sugar
1/2 cup vegetable oil

Add in 4 eggs, one at a time until well blended
Add 2 teaspoons vanilla

Mix in:
2 cups flour
2 teaspoons baking powder
1/2 teaspoon salt

Mix dough together and let chill in fridge for at least 4 hours.
Take out and roll into 1 inch size balls.  Roll balls generously in powdered sugar.
Bake on ungreased pan at 350 for 10-12 minutes.
