Poured fondant icing and glittery sugar hearts decorate these amazingly delicious Chocolate Spice Cupcakes. Chocolate cupcakes are a treat just by themselves, but but the secret is these is the cinnamon. Making poured fondant is easy, but it is a two-step process. The first step is making the fondant, which should be made and cured at least one day in advance. The second step, which can be completed just prior to covering the cupcakes, is warming and thinning the cured fondant with sugar syrup to make it pourable. The sugar syrup for the poured fondant can also be made in advance.
