In a medium bowl, whisk together the pumpkin puree, eggs, milk, vanilla, and maple syrup until smooth.
In a separate bowl, mix the oat flour, protein powder, baking powder, baking soda, cinnamon, pumpkin pie spice, and salt.
Pour the dry ingredients into the wet and stir gently until just combined. The batter should be thick but pourable.
If it’s too thick, add 1–2 tablespoons of milk.
Let the batter rest for 5 minutes. This helps the flour hydrate and gives fluffier pancakes.
Heat a nonstick skillet or griddle over medium heat. Lightly grease with butter or oil.
Pour about 1/4 cup of batter per pancake.
Cook until bubbles form on top and the edges look set, about 2–3 minutes.
Flip and cook another 1–2 minutes, until golden and cooked through. Adjust heat if they brown too fast.
Serve warm with pure maple syrup, a dollop of Greek yogurt, toasted pecans, or a sprinkle of cinnamon.
