Preheat waffle maker.
In a bowl whisk together eggs, milk, sour cream, butter, vanilla, orange zest and orange juice. Set aside.
In a large bowl mix together flour, baking powder, baking soda, pinch of salt and brown sugar. Add wet ingredients and stir to combine.
Turn waffle maker to your desired setting (we use medium) and pour in about 1 cup of the batter per batch spreading evenly all over the waffle maker. Cook until done.
Using a spatula remove waffles and serve immediately. Or keep in oven on low temp until ready to serve.
