Preheat oven to 350 degrees. Line muffin tin with paper cupcake liners.
In a large bowl, mix together cake mix, water, oil, and eggs according to package instructions.
Fill cupcake liners about ⅔ full and bake for about 18 minutes. Remove from oven and allow to cool.
Frost cupcakes with white frosting. Pour white edible glitter on a plate and roll the edges of the frosted cupcake in the glitter to coat the edge and make them sparkle.
Place a half marshmallow, cut side down in center of cupcake.
Add two half pretzel sticks on each side of the marshmallow for the snowman’s arms.
Place three mini M&Ms on top of the frosting for the buttons.
Use the black cookie icing to make eyes. Use the orange cookie icing to make an orange triangle for the carrot nose. Allow icing to dry.
