Boozy Sweets From the Big City, Margarita Cupcakes

Margarita Cupcakes with Salty Lime Frosting

Pull up a bar stool. Or an office chair. Maybe even a reclining Adirondack chair by the pool. Because no matter where you indulge in these margarita cupcakes, you’ll be transported to a dreamy beach lined with sandy towels and sun-baked flip-flops. Just hope no one steps on a pop-top and has to head on back home.

And by big city, I mean Minneapolis.

Margarita Cupcakes with Salty Lime Frosting

If you like margaritas, you’ll enjoy these light little cakes spiked with tequila and a twist of lime. Top them with a generous helping of the tart, salty frosting and it’s like licking the rim of your icy margarita.

The recipe is new to me. A fellow blogger from the Minneapolis area, Michelle Hals, shared it with me at Minnesota Blogger Conference (now Twin Cities Collective). The recipe comes from her parents who got it from her dad’s cousin when he made the treats for a high school reunion.

Thank you for sharing this family recipe with us, Michelle. And for sharing your chocolate cake with fudge frosting recipe too.

I lovingly call Minneapolis the big city because I used to live there and now I live on an acreage in southwest Minnesota.

Sweet wishes,

The salty lime frosting is the best part, but adding the simple lime syrup ensures your cupcakes will be moist.
