Lucky Charms Cupcakes for St. Patrick’s Day

Lucky Charms cupcakes feature a triple dose of luck: a Lucky Charms crust, Lucky Charms mixed into the cupcake batter, and Lucky Charms marshmallows on the frosting.

The pure sugar of the Lucky Charms cereal balances with a not-so-sweet cupcake to create a combination that is magically delicious and enjoyable for kids, adults, and leprechauns alike.

About the Lucky Charms Cupcakes’ Ingredients

About the Lucky Charms:

One glance at the photo will probably reveal that I made my Lucky Charms cupcakes with homemade Lucky Charms.  However, Lucky Charms cupcakes can just as easily be made with store-bought Lucky Charms.

About the Corn Syrup:

Both the cake and the frosting are made using homemade corn syrup. Homemade corn syrup is NOT the same thing as store-bought corn syrup.  Instead, it is a sugar syrup that has been flavored with corn.  The corn flavor imparts a cereal taste to the cupcake and gives the frosting the aftertaste of sweetened cereal bits that have been left over at the bottom of a bowl of milk.

If you plan on making these Lucky Charms cupcakes, I highly recommend that you take the time to make homemade corn syrup.  If that’s not possible, you can still make the Lucky Charms crust (recipe below), but instead of using this cupcake recipe, use a vanilla cupcake recipe (with 1 cup of Lucky Charms mixed into it), and a vanilla frosting.

For the crust

  • 2 cups crushed Lucky Charms I used my mini food processor to crush them.
  • 1/4 cup unsalted butter melted

For the cake

  • 1/4 cup homemade corn syrup
  • 1/4 cup sugar
  • 3/4 cup + 2 tablespoons cake flour not self-rising
  • 3/4 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon salt
  • 2 tablespoons unsalted butter room temperature
  • 1 large egg room temperature
  • 3 tablespoons full-fat sour cream
  • 2 tablespoons canola oil or vegetable oil
  • 1/3 cup whole milk
  • 1 cup Lucky Charms

For the corn syrup buttercream frosting (double all frosting ingredients if you like really big frosting swirls):

  • 1/2 stick unsalted butter room temperature
  • 2 cups powdered sugar
  • 1/4 cup + 2 tablespoons homemade corn syrup
  • Lucky Charms marshmallows for topping the cupcakes


Lucky Charms crust directions

  • Preheat oven to 350 F.
  • In a small bowl, mix together crushed Lucky Charms and melted butter.
  • Divide mixture evenly between ten cupcake liners. Pack it firmly into the bottoms of the liners.
  • Bake for 10 minutes.

Lucky Charms cupcake directions

  • In a medium-sized mixing bowl or bowl of a stand mixer, mix together corn syrup, sugar, cake flour, baking powder, baking soda, and salt.
  • Add butter and mix on medium-low speed for three minutes. Because there is so little butter, you'll end up with a very fine crumb texture.
  • In a small mixing bowl, whisk together egg, sour cream, and oil until smooth.
  • Add the egg mixture to the flour mixture and beat on medium speed until just combined.
  • Slowly add milk and mix on low speed until just combined. The batter will be liquidy. (Don't worry, you didn't do anything wrong. It's supposed to be that way.)
  • Fold in Lucky Charms.
  • Spoon cupcake batter over pre-baked crusts. The batter should come all the way to the top of the liners.
  • Bake for 14 minutes and then test to see if they are done. They are done when a toothpick comes out without wet batter stuck to it. If they are not done, test again in two minutes. If they are still not done, test again in another two minutes.
  • When the cupcakes are done, remove them immediately from the tins and leave them on a cooling rack (or just on your counter if you don't own a cooling rack) to cool.

Corn syrup buttercream frosting directions

  • Mix butter on high speed for three minutes until light and fluffy.
  • Slowly mix in powdered sugar.
  • Mix in corn syrup until just combined.
  • Pipe onto cooled cupcakes.
  • Top with Lucky Charms marshmallows.

I thought that these cupcakes looked like little toadstools for leprechauns.  However, there has been an important debate taking place on the Cupcake Project Facebook page about whether or not leprechauns are small enough to sit on toadstools.  Head over to the Facebook page to weigh in.

  1. Sarasays:

    Wow, so cute! These cupcakes are super adorable and look really delicious…totally perfect for St. Paddy’s! :)

  2. Ericasays:

    Very cool! Looks so pretty too. Ok I know I am gonna sound like an old lady when I say this, but your new font is so hard to read! Very pretty, but so tricky, especially on my iPhone! Any way you’d just keep it for captions or headings and not the whole body copy?:) good work with all those homemade mallows by the way! Sounds like quite the project….

  3. Stefsays:

    Erica – You are the second person that has said that to me. I haven’t changed the font and it looks fine on my screen. Any chance you could email me a screen shot so I could see what you are talking about? I would really it!

  4. Love this idea, the cases are super cute and of course the lucky charms :)

  5. Ericasays:

    Well strangely, it is back to what is has always been now! Hmmm, how weird. I will send you a pic of it goes back for some reason, but the font was an elaborate script. Well, I’m happy it somehow fixed itself for me!:)

  6. I am not sure how soon I will be making my own mini marshmallows but I totally love these!

  7. how cute! you always amaze me with your work, very impressive looks so nice !

  8. Oooo, these look sooo good. I feel the need to lick the screen but that’s not going to satisfy my need for lucky charm cupcakes.

    As I said before though, we don’t have Lucky Charms here in the UK (unless I want to pay import prices from specialist online companies) so I have to make these. I even saw the Ateco cutters in my local sugarcraft store. I picked them up and immediately thought of these! :)

  9. Anonymoussays:

    Do you imagine that these could somehow be turned into cheesecake cupcakes with a magically delicious lucky charms crust?

  10. Anonymoussays:

    Do the lucky charms in the cupcake include the cereal, or just the marshmallows?

  11. these are perfect for st patty’s day! super cute and creative!

  12. I’m absolutely obsessed with these adorable cupcakes! Lucky charms are very popular in my house. How about with a few St Patrick’s Day cupcake wrappers? ;)

  13. What a cute and sweet idea. The colorful Lucky Charms are perfect.

  14. Jeanniesays:

    That is so beautiful! I love the colors combinations!

  15. Anonymoussays:

    is there anything you could replace the corn syrup with?

  16. Anonymoussays:

    I made these cupcakes last night and they turned out AWESOME!!! They made 12 cupcakes instead of the 10 that the recipe says, which is even better :) I put some green food coloring in the frosting and printed out some cool shamrock cupcake wrappers for St. Patrick’s day to place them in. I wish I had a camera so I could take a picture. Thanks for the great recipe!

    The second I saw these I knew I had to make them and I did for my fiance’s office contest! check out the review I got from a co-worker:
    “The adorable little decorations on the top are only the start. That cupcake was multi layer perfection. Was that a Lucky Charm crust at the bottom? Really cute and tasty.”
    Just started blogging and this recipe was one of my first posts!! Thanks for the creative and delicious idea!

  19. I made these for St. Patrick’s day. I made and used the corn-flavored syrup and they did turn out quite cute. Be warned, however, that these may be the single sweetest cupcake every created. They are almost tooth-achingly sweet! Diabetics can’t be in the same room as these cupcakes. My uncle had to double his insulin dose just to be in the same house with these. :-)
