01 - In a large mixing bowl, whisk together flour, sugar, cinnamon, and baking powder until evenly blended.
02 - In a separate bowl, whisk mashed sweet potato, milk, and egg until smooth and fully incorporated.
03 - Pour the wet mixture into the dry ingredients and stir gently just until combined; avoid overmixing to maintain a light texture.
04 - Heat a griddle or nonstick skillet over medium heat and lightly coat with butter. Pour 1/4 cup portions of batter onto the surface; cook until bubbles form and edges appear set, then flip and cook until the other side is golden brown.
