Gooey Butter Cake

This is a family favorite of ours; my grandma used to make it for us and we loved it! Hope you do to!

1 cube butter
1 box cake mix
4 eggs
1 lb. powdered sugar
8 oz. cream cheese
chopped nuts (optional)

Melt 1 cube of butter in a cake pan. Mix any flavor cake mix, I used yellow, with 2 eggs and spread over bottom of pan.
Blend 1 lb. powdered sugar, 1 8 oz. cream cheese and 2 more eggs. Pour on top of other mixture. Add chopped nuts.
Bake at 325 for 45-50 minutes, or until crust is light brown. Sprinkle with powdered sugar while hot.
