I use the one from my Betty Crocker cookbook...they're DD's favorite cookie!
2 cups granulated sugar
1/2 cup vegetable oil
2 tsp vanilla
4 ounces unsweetened baking chocolate, melted and cooled
4 large eggs
2 cups all purpose flour
2 tsp baking powder
1/2 tsp salt
1 cup powdered sugar
mix granulated sugar, oil, vanilla and chocolate in large bowl. Mix in eggs one at a time. Stir in flour, baking powder and salt. Cover and refrigerate at least 3 hours.
Heat oven to 350. Grease cookie sheet with shortening.
Drop dough by teaspoonfuls into powdered sugar; roll around to coat. Shape into balls. Place 2 inches apart on cookie sheet.
Bake 10 to 12 minutes or until almost no indentation remains when touched. Cool on wire rack
