Pumpkin Cupcakes with Maple and Ginger Buttercream Frosting

I recently took a cooking class called "The Art of Cupcakes," by Chef Wynton Mann (you can check out his site at www.wyntonsworld.com), and it was so much fun!  We made five different types of incredibly delicious cupcakes: these, banana nut cupcakes with cinnamon buttercream frosting, chocolate cupcakes with strawberry mascarpone cream cheese-filling and chocolate cream cheese frosting, honey pear cupcakes with white chocolate and pistachio buttercream frosting, and vanilla coffee cupcakes with tiramisu filling and coffee buttercream frosting.  I know you're probably drooling right now just reading over that. Imagine actually biting into them.  They were all sooo good...not one of them was even close to forgettable.  And none of the recipes are available online, so I guess you'll just have to make them all from my blog(:

Yield: 12 cupcakes

Ingredients:
For the Cupcakes:
1.5 cups all-purpose flour
1 tsp. baking powder
1/2 teaspoon baking soda
1/2 teaspoon kosher salt
1 teaspoon ground cinnamon
1/2 teaspoon ground ginger
1/2 teaspoon ground nutmeg
2 eggs, at room temperature
8 oz. canned pumpkin puree
1/2 cup granulated sugar
1/2 cup light brown sugar, lightly packed
1/2 cup vegetable oil


For the Frosting:
4 oz. cream cheese, room temperature
4 oz. butter, room temperature
1/4 cup maple syrup
1 teaspoon ginger, powder
2 cups confectioners' sugar, sifted


Directions:
For the Cupcakes:
1. Preheat oven to 350 degrees.
2. Line a muffin tin with 12 cupcake liners.
3.  In a medium bowl, sift together the flour, baking powder, baking soda, salt, cinnamon, ginger, and nutmeg.
4. In another larger bowl, whisk together the eggs, pumpkin puree, granulated sugar, brown sugar, and vegetable oil.
5. Add the flour and stir until combined.
6. Divide the batter among the prepared tins and bake for 20 to 25 minutes, until a toothpick inserted in the center comes out clean.
7. Let the cupcakes cool completely before frosting.


For the Frosting:
1. Beat the cream cheese until smooth.  Add the butter and beat until combined. Add the maple syrup and ginger and beat to combine.  Add 1.5 cups of the sugar and beat on low speed until combined.  
2.  Optional: add up to 1/2 cup more of sugar so that the frosting is thick.
