[ingredients] 1 box white cake mix
¾ cup sour cream
¾ cup milk
1/3 vegetable oil
½ tsp vanilla extract
½ cup finely crushed Lucky Charms (cereal pieces only, no marshmallows)
~25 drops green food coloring
4 ½ cups powdered sugar
1 tsp vanilla
1 cup room temperature unsalted butter
1 (13 oz) container marshmallow fluff
Optional: Green sprinkles
[instructions]Preheat oven to 350 degrees and line cupcake pans with liners.
In a large bowl blend cake mix, eggs, sour cream, milk, oil, and vanilla extract.
Mix in drops of green food coloring until desired color is achieved.
Mix in finely crushed Lucky Charms crumbs until combined.
Fill cupcake liners 3/4 full with batter and bake 18-23 minutes, or until a toothpick inserted into a cupcake comes out clean.
Take cupcakes out and let cool completely.
In a medium bowl beat room temperature butter with an electric mixer. Add two cups of the powdered sugar, the vanilla, and the marshmallow fluff and mix until smooth. Continue to add the powdered sugar, a half cup at a time, mixing between each addition.
Pipe onto each cooled cupcake. Top with green sprinkles and a Lucky Charms marshmallow (do not top with Lucky Charm marshmallow until ready to eat*).
