I start by whisking the flour, baking powder, salt, cinnamon, nutmeg, and brown sugar together in my large bowl. Whisking instead of stirring helps break up any clumps in the baking powder. This step only takes a minute, but it sets the base for even fluffier pumpkin pancakes recipes down the line.
In my medium bowl, I whisk together the milk, pumpkin puree, egg, melted butter, and vanilla extract until smooth. I make sure the melted butter isn't too hot, or it can scramble the egg slightly. This mixture should look creamy and fully blended before you move on.
I pour the wet ingredients straight into the bowl with my dry ingredients and gently fold everything together with a spatula. I only stir until I no longer see streaks of flour, since overmixing is the number one thing that makes pancakes turn out tough instead of fluffy.
I let my batter sit for about 5 minutes before cooking. This little pause lets the baking powder start activating and gives the flour time to hydrate fully. It's a small step, but it makes a real difference in how tall and fluffy the finished pancakes turn out.
While the batter rests, I heat my non-stick skillet over medium-low heat and add a small pat of butter or a light spray of oil. Getting the temperature right matters here, because a pan that's too hot will burn the outside before the inside cooks through.
I pour about 1/4 cup of batter per pancake onto the hot skillet, leaving space between each one. I let them cook for about 2 to 3 minutes until bubbles form on top and the edges look set, then I flip and cook the other side for another 1 to 2 minutes until golden.
I stack the finished pancakes on a plate and keep them warm under a loose sheet of foil while I cook the rest of the batch. Serving them fresh off the skillet always gives the best texture, so I try not to let them sit around too long before everyone digs in.
