St. Patrick's Day Lucky Charms Cupcakes

I was that child. Sweet and adorable of course, but I had to have my name brand kid snacks. I mean how else could I survive??

This included all the different types of Lunchables, and other assortment of meals that may have no meaning to me today, but certainly played a daily role in my life as a child.

My cereal was a big part of that. I was a big fan of what I now realise is everything General Mills; Frosted Flakes, Cocoa Puffs, Lucky Charms, you name it.

Although I’m a lot more receptive to homemade meals now, somehow this name brand has unfortunately translated into shopping…

I guess we never change.

St. Patrick's Day Lucky Charms Cupcakes

With St. Patrick’s Day around the corner, it’s hard not to reminisce on our first childhood encounter with all things kid-rated Irish and St. Patrick’s Day themed. I remember how excited I was to get the four leaf clover hat marshmallows, those specifically, and I think I can blame my love of all things green on this.

Although we have way more St. Patrick’s Day themed goodies such as bailey’s cheesecakes and anything with well, Guinness, I wanted to go back to childhood to pluck out a cute and fun idea for cupcakes, and something non-alcoholic!

St. Patrick's Day Lucky Charms Cupcakes

There’s no reason that kids can’t get in on the fun! I had way too much fun riffling through the bag to get these for the cupcakes. All you really need is a bag of Lucky Charms cereal and these delicious cupcakes. These cupcakes are my go-to recipe, a combination of perfectly fluffy and light, but able to hold the delicious butter flavour that cupcakes should. I made some of the batter green and swirled it into the cupcakes, but you could also just make the entire batter green. It’s up to you. The frosting is also my go-to frosting and is so fluffy! The marshmallows on top were such a treat of course, and who wouldn’t feel lucky after eating a four leaf clover ?

Or four, four leaf clovers. Don’t worry, I won’t judge how many cupcakes you need to eat to feel lucky.

Just join the club.

Prep Time:

Total Time:
Serves: 15
Category: Desserts
  • 1/2 cup (1 stick) of butter, room temperature
  • 1 cup of sugar
  • 2 eggs, room temperature
  • 1 1/2 cups of pastry flour
  • 1 3/4 teaspoons baking powder
  • 1 teaspoon salt
  • 1/2 cup of buttermilk
  • 1/2 teaspoon vanilla extract
  • 1/2 teaspoon butter flavouring (optional but amazing)
  • Green food colouring
  • 3 cups powdered sugar
  • 1 cup butter, softened
  • 1/2 teaspoon vanilla
  • 2 tablespoons of milk
  • Handful of Marshmallows from a bag of Lucky Charms
  • Preheat your oven to 350 degrees F. Line a cupcake pan with 15 liners, set aside.
  • In a separate bowl, combine flour, salt and baking powder. Set aside.
  • Cream butter and sugar for 7 minutes, until creamed together, stopping to mix together every 3 minutes. Add eggs, one at a time. Mix for 30 seconds then add the other egg. Add the vanilla extract.
  • Add the flour mixture and buttermilk (alternating) to the mix in three rounds, starting with the flour and ending with it. Add butter flavoring to mix; until just mixed.

  • In a small bowl, take out ⅓ cup of batter. Add the green food colouring (a toothpick drop) and swirl until the mixture is green. Using the remainder of the batter, add a little less than 1/4 cup of batter to each cupcake liner.
  • Add a bit of the green batter into each liner, using another toothpick to swirl until each cupcake liner has green swirled into it. Baked for 25 minutes.
  • Allow to cool for 5 minutes, then remove from the cupcake pan and place on a wire rack.
  • Beat the butter and vanilla for about 2 minutes until fluffy. Add 1/2 of the powdered sugar and 1 tablespoons of the milk. Beat for about 3 minutes, until all is incorporated.
  • Add the rest of the powdered sugar and the milk. Mix for at least 8 minutes, using the spatula to mix everything together every 3 minutes, until the frosting is white and fluffy.
Putting it together
  • Pipe frosting onto the cupcakes. Add any amount of marshmallows you want on the cupcakes. I put a four leaf clover hat on top, and other assorted ones around the cupcake. Enjoy!

You can add more of less milk based on how thick you want your frosting. Add up to 1 tablespoon more than the recommended amount.

These cupcakes store in the fridge well but it would also be advised to put them in a seal proof container first.
