In a large mixing bowl, whisk together the gluten-free flour, baking powder, cinnamon, nutmeg, ginger, and salt until evenly combined.
Add the pumpkin purée, milk, eggs, maple syrup, and olive oil to the dry ingredients. Whisk until the mixture is smooth and slightly thickened, with no lumps remaining.
Let the batter rest for about 5 minutes; this allows the gluten-free flours to hydrate and helps the batter relax, making the pancakes fluffier.
Heat a non-stick skillet or griddle over medium heat and lightly oil the surface. Once hot, ladle about 1/4 cup of batter for each pancake.
Cook the pancakes for 2-3 minutes, until bubbles form on the surface and the edges look set. Carefully flip them over and cook for another 2-3 minutes until golden brown and cooked through.
Repeat with the remaining batter, adjusting the heat as needed to prevent burning. Add more oil if necessary between batches.
Transfer the cooked pancakes to a warm plate and serve immediately, topped with your favorite toppings like whipped cream, toasted nuts, or extra maple syrup.
