eggs (use the amount from the cake mix box)
3 to 4 drops green gel food color
1 cup salted butter softened
6 ounces marshmallow fluff
2 teaspoons vanilla extract
4 cups powdered sugar
3 Tablespoons heavy cream

Instructions

Preheat the oven to 350℉ (or whatever temperature is listed on the cake mix box)
Pour the cake mix into a mixing bowl.
1 box white cake mix
Replace 3 tablespoons of the cake mix with the crushed Lucky Charms.
3 Tablespoons Lucky Charms
Add the eggs, oil, and water to the cake mix according to the instructions on the box.
oil (use the amount from the cake mix box), water (use the amount from the cake mix box), eggs (use the amount from the cake mix box)
Add 3-4 drops of green food gel color to the mixing bowl.
3 to 4 drops green gel food color
Mix all the ingredients until combined.
Put cupcake liners in a cupcake pan.
Fill the cupcake liners ⅔ full with the cupcake batter.
Bake the cupcakes according to the directions on the box.
Let cool in the pan on a cooling rack.
In a clean mixing bowl, mix the butter and marshmallow fluff on medium-high speed until fluffy and combined. About 3 minutes.
1 cup salted butter, 6 ounces marshmallow fluff
Add the vanilla extract and mix for about 1 minute.
2 teaspoons vanilla extract
Add the powdered sugar and mix on low speed until combined.
4 cups powdered sugar
While mixing, pour in the heavy cream.
3 Tablespoons heavy cream
Turn the speed up to medium. Mix until the buttercream is smooth, about 1 minute.
Dip a tooth pick in the green food gel color and then wipe the inside of the piping bag with it. This will give the buttercream green streaks.
3 to 4 drops green gel food color
Add the buttercream to the piping bag and secure the end.
Pipe swirls on top of the cupcakes.
Sprinkle the Luck Charms cereal randomly around the top of the frosting. Push them in a little so they don't fall off.

Notes

I only crush the cereal part (not the marshmallows) from the Lucky Charms cereal to prevent the batter from being too sweet.
If you prefer to use unsalted butter, add 1/8 teaspoon salt to the frosting.
