Grandma's Cheese Pound Cake

Here is the "secret family recipe" that is too good not to be shared! I promise to bake one soon and add a picture!

Grandma's Cheese Pound Cake

6 eggs, separated
1/2 lb. unsalted butter (2 sticks), softened
3/4 lb. cream cheese, softened (one 8 oz. and one 3 oz. package)
2 cups sugar
1 tsp. vanilla
2 cups Presto cake flour, sifted

Beat egg whites until stiff (about 10 minutes) and set in refrigerator.
In a large bowl, mix butter, sugar and cream cheese with beaters on low speed until smooth.
Add vanilla to egg yolks and lightly mix.
Add egg yolk mixture to cream cheese mixture and beat until light and creamy.
Add Presto cake flour, 1/3 at a time and beat until smooth.
Fold in egg whites. Pour into a greased and floured 10 inch tube (bundt) pan.
Bake at 350 degrees for 55 minutes.
Cool in pan for 10 minutes before removing from pan.
Let cool, then dust with confectioner's sugar or frost with icing before serving.
Store in refrigerator.
