Pumpkin Buttercream Cupcakes

"These pumpkin buttercream cupcakes are perfect for Halloween. It's a pumpkin spice buttercream with a hint of cinnamon -- you've gotta love those fall flavors. Your kids will love you if you make these pumpkin cupcakes and it's also a great way to treat yourself. And the buttercream! Who doesn't love buttercream? It's one of our favorite frostings when making cake or cupcakes and the addition of pumpkin spice really makes this the perfect fall/halloween cupcake."
