Preheat the oven to 375°F and line a cupcake pan with liners and set aside.
In a large mixing bowl or stand mixer fitted with a whisk attachment, combine all of the cupcake ingredients until well combined, making sure to scrape down the sides as needed.
1 box dark chocolate fudge cake mix, 1 (3.9 oz.) package chocolate fudge instant pudding mix, 4 large eggs, 1 cup sour cream, ¾ cup vegetable oil, ½ cup chocolate milk, 1 tsp vanilla extract, ¼ tsp salt, 1 cup mini chocolate chips
Add a scant ¼ cup of batter to each liner so they're about ¾ full.
Bake the cupcakes for about 18 to 20 minutes or until a toothpick inserted in the center of a cupcake comes out clean.
Let the cupcakes sit in the pan for a couple of minutes before transferring to a cooling rack to cool completely before frosting.
While the cupcakes are baking, melt the chocolate melting wafers at 30-second intervals, stirring between each one, until fully melted. Transfer the melted chocolate to a piping bag with a small hole cut in the tip and pipe 48 antlers onto a parchment paper-lined baking sheet. Place in the refrigerator to set.
1 cup chocolate melting wafers
While the cupcakes are cooling, prepare the Chocolate Buttercream Frosting as indicated in the recipe instructions. 1 batch Best Chocolate Buttercream Frosting
Pipe the frosting onto the cooled cupcakes.
Add a candy bar to each cupcake to build the reindeer face on.
24 Milky Way Bite Size Candy Bars
Pipe a little frosting on the bar to attach the candy eyes (2 to each candy bar) and to attach an M&M to create the nose.
