Make yellow cake according to the box directions for a 9x13 cake. Let cool. Using a fork, poke holes all over the top of the cake. Pour sweetened condensed milk and caramel sauce over the top of the cake, letting them soak into the cake.
In a mixing bowl, whisk together banana pudding mix and milk for two minutes, until it begins to thicken. Fold in Cool Whip until completely combined. Spread Cool Whip/pudding mixture over the top of the cake.
Sprinkle on nut topping and drizzle with any leftover caramel. Store in the refrigerator until time to serve.
Notes
To store, we recommend placing it in an air tight storage container, and putting it in the fridge.
If you aren’t going to eat it for more than a week, we recommend freezing it. Again the best way to freeze it is placing it in an airtight storage container and putting it in the freezer.
