Looking for an easy St. Patrick’s day dessert that looks impressive but doesn’t take all night? Look no further. These end of the rainbow cupcakes don’t require any special skills and they’re sure to be a hit with your kids, at a St. Patrick’s Day party, or at a potluck.
Start by making your favourite white cupcake recipe, and add 1/4 cup of sprinkles to the batter for some extra rainbow fun. The sprinkles will dissolve, but you’ll be left with a cute rainbow touch to your cupcakes.

Next, make a batch of buttercream icing (I’ll share the recipe down below) and divide into three bowls. Use yellow, red, and blue gel food colouring for vibrant colours. If you’re going for more of a pastel look, the liquid colours give beautiful results too.
Next, take a piping bag and spoon in your colours 1 heaping teaspoon at a time, alternating colours as you go. Don’t worry about getting it perfect. That’s the fun of this method and what keeps it from getting too complicated.Calling all leprechauns! You'll love these easy St. Patrick's Day cupcakes.Click To Tweet
This is what your piping bag should look like when you’re done. You can use any icing tip you like, but I like the large cupcake size for best results.
