All of your ingredients you will need.
Your cake ingredients.
Preheat oven to 350.
Set up 24 muffin wrappers.
Add all your ingredients up-1/3 cup of vegetable oil, 1 1/2 cup of water, three egg whites, and Betty Crocker box mix.
Add 1 tablespoon of peppermint extract

Add 1 tablespoon of red food coloring.
Fill only half of the muffin sheet up with red batter.
On top fill the other half with the white batter.
Take your knife and swirl it so will get the marble effect.
Put into oven for 18 to 20 minutes when done cool for 10 mins.
Now it's time to make the icing.
Add all the ingredients-3 cups of powdered sugar, 2 tablespoons of milk, 5 2/3 cups of butter or margarine, and 1 1/2 of vanilla extract.
Mix it all up with mixer on a low speed.
I put it into this container so it would be easier to spread on the cupcakes or you could just use a knife. You will ice your cupcakes.
Smash the 5 candy canes that you used and sprinkle them on top of the cupcakes once you're done Icing.
Here is where you can see the neat texture of the marble you created earlier.
Here is your final product! Enjoy!
