Preheat oven to 350 degrees. Prepare cupcake pan by lining with paper liners.
Sift together flour, cinnamon, ginger, nutmeg, baking powder, baking soda and salt. Set aside.
In large mixing bowl, combine the pumpkin puree, coconut milk, oil, brown sugar, sugar, maple syrup and vanilla. Mix until well blended. Add flour mixture and stir for 1 minute.
Evenly divide cupcake batter into prepared cupcake pan. Bake for 17-19 minutes or until toothpick inserted in center comes out clean.
Cool in pans for 5 minutes, then place on cooling rack to cool completely.
To make buttercream, beat together vegan butter with shortening for 1 minute in large bowl of standing mixer. Add sifted powdered sugar, maple syrup, 2 tablespoons coffee creamer and vanilla. Beat for an additional 2 minutes, until light and fluffy, about 2 minutes (adding additional creamer if needed).
