In a large mixing bowl, sift together the gluten-free flour, baking powder, cinnamon, nutmeg, and salt. In another bowl, whisk the mashed sweet potato, eggs, almond milk, maple syrup, and vanilla extract until well combined.
Gradually incorporate the dry ingredients into the wet mixture, stirring until just combined. Be careful not to overmix to keep the pancakes light and fluffy.
Heat a non-stick skillet or griddle over medium heat and lightly grease with butter or coconut oil.
Pour ¼ cup of batter for each pancake onto the skillet. Cook until bubbles form on the surface and the edges look set, about 2-3 minutes. Flip and cook for an additional 2 minutes or until golden brown and cooked through. Serve the pancakes warm, drizzled with maple syrup, and if desired, a sprinkle of cinnamon or a dollop of yogurt.
