Ingredients:
1 cup unsweetened cocoa powder
2 cups white sugar
1/2 cup vegetable oil
4 eggs
2 teaspoons vanilla extract
2 cups all-purpose flour
2 teaspoons baking powder
1/2 teaspoon salt
1/2 cup confectioners' sugar
Method:
In a medium bowl, combine cocoa, white sugar, and vegetable oil. Beat in eggs each one in turn, at that point blend in the vanilla. Mix the flour, baking powder, and salt; blend into the cocoa mixture. Cover dough, and chill for minimum 4 hours.
Preheat oven to 350 degrees F (175 degrees C). Line cookie sheets with parchment paper. Roll dough into one inch balls. I like to use a number 50 size scoop. Coat each ball in confectioners' sugar before placing onto prepared cookie sheets.
Bake in preheated oven for 10 to 12 minutes. Let stand on the cookie sheet for a minute before transferring to wire racks to cool.
