In a mixing bowl, beat the egg together with pumpkin puree, nut butter, maple syrup, vanilla extract and all the spices (ground cinnamon, nutmeg plus pinch of salt). Whisk until smooth.
Add flour and milk to the pumpkin mixture, then stir until combined. For fluffy pancakes, do not overmix batter.
Spray a griddle or pan with cooking spray and place over medium heat. Once hot, pour one scoop of batter into the pan. Cook your pancakes over medium heat until the underside is golden and bubbles begin to appear on the surface, then flip with a spatula and cook until golden.
Serve healthy pumpkin pancakes with your favorite toppings.
