Preheat the oven to 200℉.
In a medium bowl, whisk together the flour, baking powder, salt, and pumpkin pie spice; set aside.
In a high-speed blender, add the pumpkin, sugars, eggs, milk, butter, and vanilla. Blend until smooth.
Scrape down the sides of the blender, add the flour mixture, and blend until smooth. Scrape down the sides of the blender as needed until no flour streaks or pumpkin clumps remain. Remove the blade scraping off any batter.
Preheat an electric griddle between 350℉-375℉. Lightly spray with non-stick oil spray, removing any excess with a paper towel.
Working in batches, pour batter (about ⅓ cup) onto griddle 1-inch-apart. Cook until the adges are slightly dry and bubbles form in the center of the pancakes, about 3 minutes. Turn and cook until lightly browned on the second side, about 2-3 minutes more.
Transfer the pancakes to an oven-safe platter and keep warm in the oven until ready to serve. Serve with infused maple syrup, walnut pieces, and pomegranate seeds. Enjoy!
