Who doesn’t love a sweet treat? Whether it’s a cupcake, a cookie or some ice cream: there’s no better reward than treating yourself with a decadent, sinful dessert. On National Cupcake Day, there’s no excuse NOT to indulge in something sweet to celebrate one of life’s simple pleasures: a little personal cake that’s topped with a heap of frosting and cute sprinkles, or sometimes even a whole cookie on top (because, well, why not!?)

National Cupcake Day marks the calendar every year on December 15th, and it’s a chance for all bakeries nation-wide to proudly host all kinds of specials to celebrate this favorite sweet treat. From Magnolia Bakery in NYC, to Sprinkles Cupcakes in LA, all Americans look forward to this special day- including the celebs!
