Just like Mom made...

Chocolate Crinkles 2

Mix the dry ingredients, then set aside.
1 2/3 cup flour
1/2 cup cocoa powder
1 1/2 tsp baking powder
1/4 tsp salt

Cream the butter and sugar together.
1/2 cup butter, at room temperature
1 1/4 cup sugar
Add:
2 eggs
1/2 tsp vanilla
Mix well, then mix in the dry ingredients.

Form into one inch round balls and roll them in powdered sugar. These cookies spread, so make sure you leave space between the cookies on the sheet. Bake on a greased cookie, at 350F sheet for about 10-12 minutes.
