I am so impressed by these key lime cupcakes. They’re the perfect summer cupcake idea. And the little lime on top? I feel like a genius. It’s so tasty–the zing of lime and sweet icing?! Genius.
Key Lime Cupcakes
Here at Ruffles and Rain Boots, I’m big on creating summer cupcake ideas for all tastes. Every time I can find an excuse, I make a cupcake. I’m notorious for the small, personal treats. One of the BEST I made recently was this flavorful key lime cupcake recipe.
Simple and fun, the tart bite of the lime with the sweet frosting is summer in a cupcake liner. I can’t get enough of these key lime cupcakes, so let’s get started.

Tips to Make this Key Lime Cupcake Recipe
- To make the pretty swirly cupcake icing, use a star decorating tip. Don’t try to pile on too much frosting for these – a nice swirl is more than generous.
- Put a paper straw in any summer cupcake adds fun and is an instant decoration to match any party.
- Make sure your cupcakes are cooled completely before icing. It must be said that a warm cupcake with icing is not a tasty looking treat.
