Preheat Mini Waffle Maker. Melt butter on a small pan over low heat. Shut off heat so butter is not hot when added to the mix.
Mix together the dry ingredients and set aside.
Add eggs into a bowl and beat with a whisk. Add milk, pumpkin, butter and vanilla, then mix.
Add dry ingredients into wet in three rounds, fully incorporating all dry ingredients before adding the next round. Grease the Mini Waffle Maker with butter or a small amount of non-aerosol cooking oil. Add 3 tablespoons of batter into the preheated Mini Waffle Maker and cook until the waffle is cooked through (about 5-6 minutes).
