Preheat the oven to 350 degrees F.

In a large bowl, whisk together the flour, salt, baking powder and baking soda.

In another bowl, whisk together the vanilla extract, milk and vegetable oil.

Cream together the butter and sugar with a hand-held mixer in a large bowl. Add the eggs 1 at a time and mix to combine. Alternate the dry and wet ingredients to the egg mixture, starting and ending with the dry ingredients.

Pour the batter 2/3 full into the cupcake tins and bake for 15 to 20 minutes. Remove from the oven and allow to cool before frosting.

Cut the yellow fruit chews into 1-inch squares. Spread the vanilla frosting on 1 cupcake, mounding it slightly. Use a small spoon to create a well in the center of the frosting. Put the cupcake in the baking tray and arrange the fruit chew in the well at an angle. Heat the caramel sauce for 2 to 4 seconds in the microwave and drizzle it on top of the cupcake so that it fills the well and spills over like gravy. Repeat with remaining 5 cupcakes.
