Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners.
In a mixing bowl, combine the pumpkin puree, sugar, and vegetable oil. Mix well.
Add the eggs and vanilla extract to the mixture and beat until smooth.
In another bowl, whisk together the gluten-free flour, baking powder, baking soda, cinnamon, nutmeg, ginger, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Divide the batter evenly among the cupcake liners, filling each about ⅔ full.
Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean. Let the cupcakes cool completely.
For the icing, beat the softened butter until creamy. Add the maple syrup and vanilla extract, and mix well.
Gradually add the powdered sugar, beating until smooth and fluffy.
Once the cupcakes are cool, frost them with the maple icing.
