Sweet-Potato Waffles

Preheat oven to 200 degrees F. In a large mixing bowl, combine dry ingredients. In a medium bowl, whisk together milk, sweet potatoes, eggs, and vanilla until combined. Stir sweet-potato mixture into flour mixture until combined. Stir in melted butter until just blended – some lumps will remain.

Place a wire rack on a baking pan and set in oven. Heat a waffle iron to medium-high and lightly brush grids with melted butter. Ladle about 1/2 cup batter into center of iron (grids should be full but not overflowing), close, and cook until iron stops steaming and waffles are golden brown, about 4 minutes (or make according to your manufacturer's instructions). Transfer waffles to wire rack in oven to keep warm. Repeat with remaining batter. Serve with pats of butter and maple syrup.
