Prepare and bake the chocolate cupcakes according to your recipe or package instructions. Allow them to cool completely on a wire rack before decorating to prevent frosting from melting.
Spread a thick layer of chocolate frosting over each cooled cupcake. Make sure the frosting reaches the edges so the decorations stay in place.
Break each pretzel twist in half to create antlers. Gently press them into the top of the cupcake, angling them slightly outward.
Press two candy eyes into the frosting below the antlers. Space them evenly so the reindeer face looks balanced.
Place one red candy just below the eyes and gently press it into the frosting. This final touch brings the reindeer to life.
