Preheat the oven to 350 degrees, and line a cupcake pan with cupcake liners.
In a large bowl, beat the cake mix, water, oil, and eggs for 3 minutes. Divide the batter between the cupcake liners.
15.25 oz box chocolate cake mix, 1 cup water, ½ cup oil, 3 eggs
Transfer the pan to the oven, and bake for 9-12 minutes, or until a toothpick inserted into the center of a cupcake comes out clean.
Remove cupcakes from the oven, and allow to cool for 1 hour.
Once cooled, use a skewer stick to poke 4-5 holes into each cupcake (towards the center).
Add 2 tbsp of caramel sauce to a mini squeeze bottle (or you can use a piping bag fitted with a cookie icing tip with a small hole). Then drizzle a small amount of caramel sauce onto the cupcakes, using a skewer stick to help guide the caramel into the holes.
4 tbsp caramel sauce
Add the remaining 1-2 tbsp of caramel sauce to the frosting, and whip with the mixer for a few minutes to help fluff it up.
4 tbsp caramel sauce, 16 oz container buttercream frosting
With a piping bag fitting with the 1A frosting tip, pipe frosting into the center of each cupcake.
Cut the Milky Way bars in half on a diagonal, then stick them into the center of the frosting as shown. Refrigerate for 5-10 minutes to help them stay in the frosting.
24 mini Milky Way Candy bars
Add the chocolate sauce to a mini squeeze bottle (or you can use a piping bag fitted with a cookie icing tip with a small hole), then drizzle the chocolate over the cupcakes.
2 tbsp chocolate syrup
