In a large bowl, whisk the flour, brown sugar, baking powder, baking soda, salt, cinnamon, ginger, nutmeg, and cloves until well combined.
In a medium bowl, whisk the pumpkin purée, milk, egg, melted butter, and vanilla extract until smooth.
Pour the wet mixture into the bowl of dry ingredients. Stir gently until just combined. Do not overmix; a few small lumps are fine. Let the batter rest for 5 minutes.
Heat a lightly buttered nonstick skillet or griddle over medium heat.
Pour about ¼ cup of batter per pancake onto the hot skillet. Cook for 2 to 3 minutes, until bubbles appear and the edges look set.
Flip once and cook for another 1 to 2 minutes, until golden brown and cooked through.
Repeat with the remaining batter, greasing the skillet as needed.
Serve warm with maple syrup, butter, whipped cream, chopped pecans, or your preferred toppings.
