1 (5.9 oz) box instant chocolate pudding mix
1 ½ cups milk, chilled
1 (16 oz) frozen whipped topping
Preparation
Preheat oven to 350 degrees F and grease a 9×13-inch baking dish.
Cake batter: In a large bowl, mix together the cake mix, water, oil, and eggs until smooth. Set aside.
Filling: In another large bowl, mix together the ricotta, eggs, sugar, and vanilla until well combined.
Transfer cake batter into the prepared baking dish and spoon filling on top (filling will sink as cake bakes).
