Mix Dry Ingredients: In a bowl, whisk together flour, sugar, baking powder, baking soda, cinnamon, nutmeg, ginger, and salt.
Mix Wet Ingredients: In a large bowl, whisk pumpkin puree, milk, egg, oil, vinegar, and vanilla.
Combine & Rest: Add dry ingredients to wet ingredients, stir until combined, and let the batter rest for 5–10 minutes to bubble.
Heat Griddle: Preheat griddle to 325°F or lightly grease a skillet over medium heat.
Cook Pancakes: Pour ⅓ cup batter onto the hot surface. Cook 1½–2 minutes per side, flipping when bubbles form and edges set. Pancakes are ready when golden brown.
Serve: Top with butter, warm maple syrup, and optional toasted pecans for extra crunch.
