Here it is, Saturday morning and Cinco de Mayo, and it's time for another Cupcake Saturday post. Going along with our fiesta theme for this week, we have a Mexican Hot Chocolate cupcake for you. It is a chocolate cupcake with a kick. Using chili powder, we gave these a little spice to them. They are topped with a cream cheese frosting to tone them down a little, but since they still needed some heat, the cupcakes are sprinkled with some more chili powder. They're perfect for tonight's fiesta celebration!
