In a large bowl, whisk together mashed sweet potato, milk, butter, egg, and vanilla extract.
Add flour, cornmeal, sugar, baking powder, cinnamon, and sea salt. Stir until just combined.
Let the batter rest while you heat up the waffle maker. Once heated, add ¼ cup of the batter into the waffle maker for mini waffles, or ½ cup for regular waffles.
Cook for 3-4 minutes until crisp on the outside and cooked through on the inside. Repeat with the remaining batter.
Top with your favorite toppings, and enjoy!
