How to Make St. Patrick’s Day Cupcakes
This decorating project is quick and kid-friendly once the cupcakes are baked and cooled.
- Prepare the cake batter according to the box directions.
- Line a cupcake pan with green liners. Fill each liner about halfway with batter and bake per package instructions. Allow cupcakes to cool completely before decorating.
- Fill a piping bag with white frosting and fit it with your chosen tip. Pipe a swirl starting in the center and working outward and upward to create a fluffy cloud of frosting.
- Paint the Golden Oreos with gold mist food paint to resemble coins. Let the paint dry, then carefully insert a toothpick through the center of the cream filling and position the cookie toward the back of the cupcake to look like a pot of gold.
- Thread four mini marshmallows onto a toothpick to form a cloud and place them on top of the frosting.
- Cut Xtreme Airheads into one-third length sections. Pair two sections together and gently curve them between the marshmallow cloud and the cupcake to form a rainbow.
- Remove all toothpicks before serving. If toothpicks are used only for assembly, make sure they are fully removed so cupcakes are safe to eat.

What Is the Pot of Gold at the End of the Rainbow?
The pot of gold is a familiar piece of Irish folklore tied to leprechauns. In stories, leprechauns guard hidden treasure, often described as a pot of gold at the rainbow’s end. Since rainbows have no actual end, the tale emphasizes the trickiness of finding that treasure without the help of a leprechaun.
In these cupcakes, the concept is playfully represented: the cupcake is the pot, a painted Golden Oreo acts as a gold coin, and Airheads form a rainbow with marshmallows as clouds. It’s a cute, edible nod to the legend.
