Pre-heat the oven to 350 degrees. Fill a 12 cup muffin pan with cupcake liners.
TO MAKE THE CUPCAKES: Whisk together the eggs, butter, milk and Pumpkin Bread Mix. Pour into the prepared muffin pan and bake for 25-30 minutes.
TO MAKE THE FROSTING: Combine the butter, powdered sugar, milk and ¼ cup of the salted caramel sauce in a bowl. Mix until smooth.
Allow the cupcakes to cool completely, then pipe a swirl of frosting onto each. Pour remaining salted caramel sauce over the frosting, then top with caramel corn.
