Using an electric hand or stand mixer, cream the butter, and beat until light and fluffy (about 2 minutes). Mix in the vanilla extract.
Slowly mix in the powdered sugar, 1 cup at a time, while adding a bit of the flavored creamer in between each cup. Continue to mix for 1 minute or until creamy. Add food coloring until desired color is achieved. For the Grinch green, you can also use green gel food coloring. Some people have mixed 4-6 drops of yellow and 2-3 drops of green.
Prepare piping bag and fill bag with frosting and frost your cupcakes.
Add a large red candy heart to each one of the cupcakes. Enjoy!
