Ricotta Cheese Cake

1 Box Yellow Cake Mix, you can make your own cake mix but the point of this recipe is to be quick and easy.
2 lb Ricotta cheese, or fine curd cottage cheese if you want, Ricotts is much better
3 extra large eggs
1 tsp vanilla
1 tsp lemon juice
1 C powered sugar, optional

Preheat oven to 350F
Prepare cake mix and pour into 9"x13" pan
Beat the cheese, eggs, vanilla, and lemon juice until smooth
Spread evenly over the cake mix.
Bake for 1 hour. A knife comes out clearn when it is done.
During baking the cheese and cake will swap places.
If desired, sprinkle the powdered sugar over the cake when it is cool. I prefer it without the sugar since I don't like sweet food.
