In a bowl, mix the dry cake mix with the milk and margarine.
Pour 1/2 the batter into the pan and gently spread it out. It will be very thick.
Place remaining batter in the fridge.
Place in the oven for 6 minutes.
Meanwhile, unwrap the caramels into a glass bowl and add 1/3 cup evaporated milk.
Microwave on high for 30 second intervals, stirring between until smooth.
Remove the brownies from the oven and sprinkle with chocolate chips.
Pour the caramel over the chocolate.
Sprinkle chopped candy bars over the caramel.
Remove the batter from the fridge and gently pat a tablespoon or so into the palm of your hand. If it sticks run your hands under cool water or spray with a little nonstick spray.
Place each piece over the caramel and snickers like a patchwork quilt until all of the caramel and candy bars are covered.
You can also place saran wrap next to the pan and press the dough onto that in the exact size of the pan. Just measure by doing the length and then moving the pan to the end to measure the width. Carefully flip it onto the caramel. Bake an additional 16 minutes.
Remove from the oven all allow to cool before serving.
You can also place in the fridge to help the caramel really set up which makes for easier serving.
Notes
These brownies can be wrapped in plastic wrap and then foil, or placed in a freezer bag and frozen for up to 4 months.
