Lucky Charms™ Surprise-Inside Cupcakes to Make with Your Kids

By Heather Baird
Created January 10, 2017
Sure to delight the little leprechauns in your life, these charming treats are easy enough for busy moms and dads to make.

I love desserts that double as entertainment, like these surprise-inside cupcakes. They’re sure to delight the little leprechauns in your life, and best of all, they’re easy for busy moms and dads to make. One batch makes 24 servings, making this recipe a no-brainer for classroom parties and other school functions, too! 

Besides how easy they are to make, my favorite thing about the “surprise inside” is how the Lucky Charms marshmallows become soft inside the cupcakes. If you serve the cupcakes right after filling them the marshmallows will be crunchy, but fill them ahead of time and the marshmallows become soft and pillow-y. It makes them completely crave-worthy…you may have trouble stopping at just one! 

First, gather all the ingredients to make the cupcakes: Betty Crocker SuperMoist yellow cake mix, water, eggs and oil. Follow the instructions for the batter as directed on box, using the instructions for cupcakes as your guide.


While you wait for the cupcakes to bake and cool, begin separating the marshmallows from a box of Lucky Charms cereal, a great task for little hands to help with. The most difficult part of this process is restraining yourself from eating all the charms you find!


After the cupcakes have cooled for about 30 minutes, cut a divot out of the center of each cupcake, about 1-inch deep, reserving cut-out cake pieces for later use.


Fill each with 1 tablespoon Lucky Charms marshmallows (about 10 to 12 pieces). At this point you may also sprinkle in a few rainbow jimmies. I did this with my second batch of cupcakes and I really love how festive they looked. It doubles the fun, and gives them a bit rainbow-like flair.


Trim the reserved cake pieces flat and cover the hole in the filled cupcakes.


Spoon Betty Crocker Whipped Fluffy White frosting into a medium bowl; stir in enough food color until desired green color. Transfer the frosting to a piping bag fitted with a large star tip and pipe on the frosting. (You can also frost cupcakes with an offset spatula.) Garnish with rainbow sprinkles.


Store cupcakes at room temperature loosely covered with plastic wrap.
