Double Chocolate Cookies

I had a request for double chocolate cookies.  My mom used to make these for me as a kid and they are my favorite.

2 squares unsweetened chocolate
1/4 cup shortening
1 cup sugar
2 eggs
1 tsp vanilla
1 cup flour
1 tsp baking powder
1 cup chocolate chips
1/4 cup icing sugar

Preheat over to 350 degrees.
Melt unsweetened chocolate squares with shortening, but do not boil.
Add sugar and mix well.
Quickly mix in eggs one at a time.  Do not allow the eggs to cook in the warm chocolate mixture.
Mix in vanilla, once both eggs have been combined with the chocolate mixture.
Add flour and baking powder and mix well.
Fold in chocolate chips.
Use 2 spoons to make balls of dough and roll them into the icing sugar.
Place on greased cookie sheet and bake for 10 to 12 minutes.
