To Prep: Preheat oven to 350°F and place cupcake liners in a regular size muffin pan.
Prepare the cupcake batter according to package directions. Scoop batter into the prepared pan, filling each cup no more than 3/4 of the way.
Bake for 15-20 minutes, or until a toothpick inserted in the middle of cupcake comes out clean. Remove from oven and transfer to a wire rack to cool completely before frosting.
If making homemade buttercream icing, combine the three frosting ingredients listed above in the bowl of a stand mixer (or in a large bowl using a handheld mixer); mix until stiff peaks form (about 2-3 minutes).
When the cupcakes have cooled, top each one with a generous layer of white frosting.
To decorate, we dusted each frosted cupcake with sugar sprinkles. Then we added an ornament topper icing decoration and colorful edible balls to look like festive Christmas ornaments.

Notes
Nutrition information is provided as an estimate only and may vary based on exact ingredients used.Prep Tips:
Cupcakes - You can use any flavor of cake mix that you like for this recipe. You can also use your favorite homemade cupcake recipe. Be sure the cupcakes are completely cool before frosting and decorating.
Frosting - While you can use store-bought frosting for these cupcakes, I find that homemade buttercream icing holds its shape and stays in place better. I listed the ingredients to make homemade vanilla buttercream in the recipe card.
Decorating - I linked to the ornament topper decorations that we used in the supply list. If they become unavailable (they can be hard to find) you can also make your own by piping candy melts onto parchment paper in a similar shape and letting it dry.
Storage - Keep cupcakes in an airtight container at room temperature for up to 5 days. If decorated, do not stack on top of each other.
