Prepare waffle maker by preheating and greasing (spray works best).
In a large bowl whisk together dry ingredients, flour through orange zest. Set aside.
In a medium bowl combine pumpkin puree (or applesauce) with oil. Add in eggs one at a time, whisking gently.
Add in vanilla, Trop50 and milk; whisk until smooth.
Pour wet ingredients into large bowl of dry ingredients, whisking together gently until smooth. Batter will be somewhat thick, but not too drippy.
Scoop about 1/3 cup of batter into preheated and greased waffle maker, and allow waffle to fully cook until lightly golden. I waited until I heard sizzling, which was bout 4-5 minutes. Each waffle iron is different, so be sure to follow your waffle manufacturer’s instructions.
Gently remove and transfer to warm oven before serving. Enjoy with your favorite toppings!
