  • Lucky Charms Marshmallows: These cereal marshmallows are the hidden gems in your cakes. They add a nostalgic sweetness and a surprise element to every bite.

  • Preheat the oven and prepare the cupcake batter in a large bowl per the box’s instructions. Optional: Add green food coloring to the cake batter.
  • Bake cupcakes. Allow cupcakes to cool completely on a wire rack after baking.

Expert Tips 

  • To ensure even cooking, fill each cupcake liner equally with batter. A cookie scoop can help with this.
  • For a more vibrant color, consider using gel food coloring instead of the liquid variety. It delivers a stronger color without changing the consistency of your batter.
  • When hollowing out the cupcakes, be careful not to dig too deep, as this could cause the base to crumble.
  • To pipe frosting like a pro, start at the outer edge of the cupcake and work your way toward the center in a swirling motion.
  • When sprinkling edible glitter or sprinkles, do so over a clean baking sheet to catch any excess and prevent mess.

Storing Tips 

These cupcakes can be stored at room temperature in an airtight container. These cupcakes will last for around 3-5 days on the counter. You will find they begin to dry out after a few days. I always recommend eating them within the first 2 days of making.

In terms of freezing, you can freeze cupcakes for 3-4 months in a proper container. Thaw on the counter and then enjoy the cupcakes later!

What To Serve With Lucky Charm Cakes

These cupcakes are so fun and are perfect for St. Patrick’s Day dessert but don’t box these cupcakes in. Serve up these cereal cupcakes when you do breakfast for dinner. Or you can do these cupcakes for a birthday party if you are looking for a lucky theme.

Recipe FAQs

Can you buy just Lucky Charms marshmallows?

You can buy just the marshmallows if you don’t want to buy a box of Lucky Charms cereal. But, also know you can buy a box of cereal and pick out some of the marshmallows if you want. It takes just a few minutes to do.

How to know when the cupcakes are done?

Take a toothpick and stick it in the center of the cupcake. If the toothpick comes out clean of wet batter, the cupcakes are done baking. Then place on a cooling rack and allow the cupcakes to fully cool.

What to do with leftover cupcakes from filling cupcakes?

You can just eat the cupcake that you removed to fill the centers of the cupcakes. Or you can crumble the cupcake add a little frosting, and roll it into balls. Then dip in a chocolate candy melt to make cake bites or put on a stick for a cake pop.
