A light and fluffy lime cupcakes recipe full of key lime flavor and topped with a tangy lime buttercream frosting! These Lime Cupcakes are made with fresh lime juice and zest making them perfect for a summer party, picnic, or bbq. Best of all, they are easy to make!
Fresh citrus desserts have always been a favorite of mine and I have come to find that lime desserts seem to be vastly underrated! This cupcake recipe was inspired by my partnership with Yankee Candle and their delicious Vanilla Lime candle. I love taking inspiration from their scent combinations, as evidenced by these Lemon Lavender Cookies, this Easy Lemon Tart, and this citrus Honey Cake!
I knew I had to give you all this recipe when Michael kept telling me how amazing they were. He won't break his no sugar rule for just any dessert, so I knew this was a winner! He said he loves the key lime tang of these lime cupcakes and I must say that I do too. Especially the lime buttercream frosting!

Lime Cupcakes Frequently Asked Questions
The short and sweet of it... Use room temperature ingredients, don't over-mix or under-mix, only fill your cupcake liner ⅔ of the way full, if your cupcake fully bounces back when you touch the top it is ready to come out of the oven, and allow your cupcakes to cool completely before frosting.
You can usually spot a key lime because they are smaller and rounder in size than regular limes. Flavor wise they are more aromatic, with a tarter and more floral juice.
If you can't get your hands on key limes, regular limes will work just fine! Also, I highly prefer fresh lime juice no matter the kind of lime over the bottled key lime juice.
The absolute easiest way to frost cupcakes is by using a cookie dough or ice cream scoop. Simply put a scoop of frosting in the middle of the cupcake and smooth out with a spatula or the back of a spoon.

In the bowl of a stand mixer fitted with the paddle attachment, whip the butter on medium speed until smooth. Add about half of the powdered sugar and mix until smooth.

Pipe the frosting onto the cupcakes using a large round pastry tip and top with lime wedge and leftover zest.
