This is delicious not like a wet cheese at all. Spray a round spring form pan with Pam. You can also use a 9" square pan. Make a yellow cake mix exactly as printed on the package. Stay away from the ones with pudding in them if you can. Pour into pan and set aside. Combine 2 lbs of Ricotta Cheese, 4 eggs, 3/4 sugar and 1 tsp. vanilla. If you are using true vanilla only use 3/4 teaspoon. Take the ricotta mixture and spoon it evenly over the unbaked cake mixture. Bake at 350 degrees for about 1 hour or or until the cake is light brown and a toothpick comes out clean. Don't fret this cake takes time to cook just keep checking it. Remove from oven, place on rack to cool. When cool move to a plate and place in fridge for several hours. Slice and serve with blueberry pie filling topping drizzeled over the top.
