01 - Preheat oven to 375°F. Line a 12-cup muffin tin with paper liners or grease lightly.
02 - In a medium bowl, whisk together all-purpose flour, baking powder, baking soda, salt, cinnamon, ginger, and nutmeg until well combined.
03 - In a large bowl, beat together pumpkin purée, eggs, vegetable oil, milk, light brown sugar, granulated sugar, and vanilla extract until smooth.
04 - Add the dry ingredients into the wet mixture and stir just until incorporated, being careful not to overmix.
05 - Gently fold in shelled edamame and roasted pumpkin seeds until evenly distributed.
06 - Divide batter evenly among the prepared muffin cups, filling each about three-quarters full.
07 - In a small bowl, toss pumpkin seeds and panko breadcrumbs with olive oil and a pinch of salt. Sprinkle the topping mixture evenly over each muffin.
08 - Bake for 22 to 25 minutes, or until a toothpick inserted in the center of a muffin comes out clean.
09 - Allow muffins to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
