Combine wet ingredients with dry ingredients, stirring until just mixed.
Cook until bubbles form on the surface and the edges look dry, about 2-3 minutes.
Flip and cook for another 2-3 minutes until golden brown.
Heat a non-stick skillet over medium heat and lightly grease with butter or oil.
In a large bowl, mix flour, baking powder, baking soda, cinnamon, and salt.
In another bowl, whisk mashed sweet potato, eggs, milk, vanilla, and brown sugar until smooth.
Pour 1/4 cup of batter onto the skillet for each pancake.
Serve warm with maple syrup, fresh fruits, or your favorite topping.
