1. Preheat the oven to 350°F. Line 10 holes of a 12-cup muffin pan with liners. In a large bowl, combine 1 cup pumpkin purée, ¼ cup of the maple syrup, almond meal, eggs, baking powder, 1 teaspoons cinnamon, ginger, a pinch of salt and 1 tablespoons of the chia seeds and beat with a wooden spoon until smooth. Stir in chopped nuts.
2. Divide mixture among the 10 cupcake liners. Bake 25 minutes. Remove muffins from pan and allow to cool 30 minutes on a wire rack.
3. While muffins bake, combine the reserved pumpkin purée, cream cheese and remaining cinnamon and maple syrup. Cover and chill until muffins are ready to be frosted.
4. Spoon pumpkin-cream cheese mixture into a piping bag with a star tip and pipe on top of muffins. Sprinkle with remaining chia seed right before serving.
