To make this frosting, you’ll need some salted butter, powdered sugar, a few juicy limes (you’ll need the zest and the juice, so make sure they’re pretty good limes all-around), and some coconut extract.
To zest limes, I really love using a Microplane. I’ve told y’all this before, but really, it’s one of my all-time favorite kitchen tools (and I realized I’ve been using this same Microplane for almost 10 years and it’s just as amazing as it was the day I got it!)
Place all the ingredients in a mixing bowl or the bowl of a stand mixer…
And beat on high speed with an electric mixer until light and fluffy.
Pipe on top of vanilla cupcakes, spread on your favorite yellow cake, do the whole aforementioned sugar cookie bar trick, spread it on top of sugar cookies, or sandwich it between graham crackers or Nilla Wafers.
