In a bowl, mix together the flour, baking soda, baking powder, cinnamon, nutmeg, and salt until combined.
In another bowl, whisk the granulated sugar, light brown sugar, eggs, and 2 tablespoons of maple syrup. Incorporate the pumpkin puree and vegetable oil.
Gradually combine the dry mixture with the wet mixture, stirring gently until just mixed.
Transfer the batter into a greased loaf pan and bake for approximately 60 minutes, or until a toothpick inserted into the center comes out clean.
Prepare the glaze by whisking together powdered sugar, 1 tablespoon of maple syrup, and whole milk in a small bowl until smooth.
Allow the bread to cool before drizzling the glaze over it and serve with your favorite beverage.
