Preheat your oven to 350°F (175°C). In a large mixing bowl, combine your vanilla cake mix, eggs, milk, and softened butter. Mix until smooth, then add a few drops of sky blue food gel coloring.

Line a cupcake tray with paper liners, then evenly distribute the cupcake batter into each liner, filling them about two-thirds full. Bake for 12-14 minutes and cool completely.

Prepare the vanilla buttercream by beating softened butter until creamy. Gradually add sifted powdered sugar, then increase speed. Add vanilla extract and heavy cream until fluffy.

Pipe a dollop of buttercream onto each cooled cupcake and coat with winter-themed sprinkles.

Pipe two additional dollops of buttercream for the snowman's body and add facial features with sprinkles for eyes and nose.

Finish by adding ear muffs made of sprinkles and jimmies for a charming touch.
