In a medium mixing bowl, whisk together the Bisquick mix, cinnamon, nutmeg, and brown sugar.
In a separate bowl, combine the pumpkin puree, milk, egg, and melted butter until smooth.
Gradually add the wet mixture to the dry mixture, stirring until just combined. Avoid overmixing to keep the pancakes fluffy.
Heat a non-stick skillet or griddle over medium heat and lightly coat with cooking spray or butter.
Using a cookie scoop or small ladle, pour small amounts of batter onto the skillet to form pancakes about 3–4 inches in diameter.
Cook for 2–3 minutes on each side until golden brown and fully cooked.
Serve warm with maple syrup, whipped cream, and a sprinkle of chopped walnuts.
Enjoy these easy and fluffy pumpkin pancakes for a cozy fall breakfast or brunch!
