In a large bowl, combine the flour, baking powder, baking soda, salt, and pumpkin pie spice.
Whisk the pumpkin, yogurt, milk, coconut oil, maple syrup, egg yolks, and vanilla.
Pour the dry ingredients into the wet ingredients and stir until just combined.
Beat egg whites until stiff. Fold into the batter.
Pour some of the batter into a waffle maker, spreading it out. Cook according to directions (for my waffle maker, I used 2 cups batter to make 4 waffles). Repeat with the remaining batter.
Top waffles with a dollop of siggi’s yogurt, maple syrup and/or chopped pecans
