Coco an Ut Cookies

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Preheat the oven to 400°F (200°C).
In a bowl, cream together the sugar and butter.
Add the sour cream, baking soda, and eggs; mix until soft.
Roll the dough thin and cut into desired shapes.
Bake in the preheated oven until lightly golden.
For the icing, beat the egg whites until stiff.
Gradually add the sugar and stir in the coconut.
Spread the icing on the cookies after they are baked.
