Another sweet potato recipe - I really like this, although it is a little heavier than your typical waffle.
1 3/4 cup flour
1 tablespoon sugar
1 tablespoon baking powder
1 teaspoon salt
1/2 teaspoon cinnamon
1/2 teaspoon nutmeg
3 eggs, yolks and whites separated
1 1/2 cups milk (room temperature)
1 to 2 tablespoons honey (optional)
6 tablespoons butter, melted
1 cup pureed sweet potatoes (I used 1 can cut sweet potatoes and blended them)
Heat waffle iron.
Whisk together: flour, sugar, baking powder, salt, cinnamon, nutmeg in a medium bowl.
In a small bowl put the egg yolks, milk, honey, butter and sweet potatoes. Blend together well. Pour into dry ingredients and mix with a spatula JUST until combined. Whisk egg whites until stiff peaks form. Fold gently into the batter. Put about a 1/3 cup of batter on each side of the waffle iron (I used the rectangle waffle iron). Cook according to manufacturers instructions.
Makes about 8 waffle squares.
