Lucky Charms Cupcakes with Cereal Milk Frosting

How to make lucky charm cupcakes? 

There is nothing wrong with using a cake mix to make cupcakes, but every once in a while, I like to bake completely from scratch. This recipe is unique in that it uses both oil and butter in the ingredients. You will whisk together a flour mixture, then in a separate bowl, beat together the butter, oil, and sugar until well combined. Finally, you will beat together the eggs, milk, and vanilla. They all get combined then placed in regular-size muffin cups (you will need two muffin pans!) and then baked.

How to make cereal milk?

Cereal milk makes these cupcakes and frosting super unique! You know the yummy milk left in the bottom of your cereal bowl? It’s so good, so why not use it?! You are going to toast your cereal in the oven (without the marshmallows), let it cool, and then soak it in milk for 15 minutes. After 15 minutes, you are going to toss the cereal but keep the milk. This recipe calls for 2 cups of milk, but you won’t use it all in the final recipe. A lot of it will soak into the cereal, so you are really ending up with a little over a cup and that will be split between the cupcake batter and the icing.
