Step 1

Preheat oven to 350 degrees F and spray a 9x13 inch pan with nonstick spray.

Step 2

In a large bowl, mix together cake batter according to package instructions.

Step 3

Pour the cake batter into the prepared baking dish. Spread to fill the pan evenly. Set aside (do NOT bake yet).

Step 4

In another bowl, use an electric mixer to beat together ricotta cheese, eggs, sugar, and vanilla extract until smooth.

Step 5

Carefully pour the cheese mixture evenly over the top of the cake batter. Spread to cover cake as best you can (the layers will switch during baking).

Step 6

Bake the cake for 1 hour.

Step 7

Remove from oven and allow to cool completely before frosting.

Step 8

To make frosting, whisk together pudding mix and milk until combined and slightly thickened (about 1-2 minutes). Carefully fold the whipped topping into the pudding until combined.

Step 9

Spread frosting on top of cooled cake. Cover and refrigerate at least 6 hours before serving.
