Arrange the biscuits on a cookie sheet in a single layer with their sides touching. With your hands or a rolling pin, flatten them to a 1/2-inch thickness. Bake according to package instructions. Remove from oven and let cool for 2 minutes before adding toppings.

In a small bowl, mix the cream cheese, sugar, and vanilla until well combined. Spread over the biscuit crust. Top with apples and nuts and drizzle with caramel. Store any leftovers in the refrigerator.
