In the mixing bowl of a stand mixer, add the brownie mix, eggs, oil, and milk, and mix until all ingredients are well blended, then mix on high for 1 minute.
Line the bottom of a 9X9 inch pan with parchment paper, and pour half of the brownie batter in the pan.
Pour half of the carton of Caramel on top of the Brownie batter.
Break up about half of the package of Milky Way bars and sprinkle them all over the top of the caramel.
Pour the other half of the Brownie batter over the Milky Way bars, and bake according to package directions.
While the Brownies are baking, open the rest of the Milky Way bars and break them in half, and set aside.
When the Brownies are done, remove from the oven to a wire rack and allow to cool completely.
When Brownies are cool, spread on chocolate frosting, and place the broken Milky Way bars into the frosting. Cut into 3 X 2 inch pieces, serve, and ENJOY!
