Cupcakes
Preheat your oven to 350 degrees F. Lightly grease and flour muffin tins (or use liners)
Combine the first 5 ingredients and blend well
Beat in the sugar and spices
Fill the muffin tins 3/4 of the way full and bake for 30 minutes.
Frosting
While the cupcakes are baking prepare the frosting.
In the bowl of a stand mixer whip the butter and cream cheese with the paddle attachment. Gradually increase the speed until it is mixed thoroughly.
Carefully add in the powdered sugar while mixing at low speed. Increase the speed once the sugar is in and mix until fluffy.
Cool the cupcakes then pipe or spread the frosting on top.
