Shamrock Cupcake Ingredients

One of my favorite parts about these cute cupcakes is how easy they are to make.

To put this fun St. Patrick’s Day dessert together, you’ll need a boxed cake mix, premade icing, green food coloring, chocolate coins, and a bag of Lucky Charms marshmallows.

Those adorable marshmallows are the secret ingredient in these cute St. Patrick’s Day cupcakes. And while the marshmallow mix also includes adorable hearts and moon shapes, you’re going to use the green shamrocks for your cupcakes.

To make these easy cupcakes, you’ll need two shamrock marshmallows per cupcake, which means you’ll need a total of 48 shamrock marshmallows.

Where to Find Shamrock Marshmallows

You can find those cute shamrock marshmallows in Lucky Charms marshmallow bags, which are sold in most major superstores (like Target and Wal-Mart) and grocery stores.

They can be found in the baking aisle along with the other traditional marshmallows. You can also purchase your Lucky Charms marshmallows on Amazon.

How to Make St. Patrick’s Day Cupcakes

To make these simple cupcakes, start by mixing your cake mix according to the package instructions. Since this recipe uses a simple white cake for the cupcakes, you can use your favorite cake mix or whip up your favorite white cake recipe. Either way, they’ll taste amazing!

After mixing the cake batter, prepare a cupcake pan by lining it with cupcake liners. I used a variety of colors of cupcake liners to create a rainbow with my cupcakes, but these cute shamrock cupcakes would also look adorable with green liner or fun St. Patrick’s Day cupcake liners.

Fill each cupcake liner 2/3 of the way full of white cake batter. Then, top each cupcake with a shamrock marshmallow. Gently push the marshmallow into the batter, making sure not to cover it with cake batter. Then, place the cupcakes in the oven and bake them according to the package instructions.

After your cupcakes are finished baking, remove them from the oven and allow them to cool in the pan for a few minutes. When it’s safe to touch the pan, place the cupcakes on a wire cooling rack to cool completely before you start decorating.

Decorating the Shamrock Cupcakes

Make sure your cupcakes are cooled completely before you start decorating to prevent the icing from melting off your cupcakes! While your cupcakes are cooling, prepare your icing by mixing green food coloring into your jar of icing.

I have found that using gel food coloring is the best way to tint your icing. It provides a vibrant color without compromising the stability of your icing by adding too much liquid to the frosting.

To make sure your food coloring gets fully mixed into your icing, scoop the premade icing from the jar into a bowl. Add the food coloring a little bit at a time, mixing between additions, until your desired color is reached.

When you’re happy with the shade of green of your icing, spoon it into a piping bag and pipe the icing onto the cupcakes. Finish decorating your cupcakes with a chocolate coin on top and another shamrock marshmallow.
