maple syrup, jam, butter and assorted fresh fruit for serving
Instructions
In a large mixing bowl, use a whisk to sift together flour, sugar, baking powder, baking soda, salt and cinnamon.
In a separate bowl, whisk together buttermilk, egg yolks, butter and vanilla. Add to dry ingredients mixing just until fully moistened.
Using an electric mixer on high speed, beat egg whites with cream of tartar until stiff peaks form. Gently fold into batter. Batter will be lumpy.
Spray both sides of the preheated waffle iron with nonstick cooking spray. Pour in enough batter to lightly cover the surface of the iron, about 1/2 to 3/4 cup, depending on size.
Close iron cooking until waffles have crisp and golden exteriors, about 5 minutes or according to manufacturer recommendation.
Cook waffles in batches. Repeat spraying the waffle iron with cooking spray as needed. Keep waffles warm between batches in a 200°F oven in a single layer on a sheet pan, until serving.
Serve immediately with butter, drizzled with syrup or with jam and fresh berries.
