For waffles: In a medium bowl, whisk together flour, sugar, baking powder, baking soda and salt. Make a well in the center of the mixture; set aside.
In a separate bowl, whisk together eggs, buttermilk, oil and vanilla. Pour into the bowl with the dry ingredients. Stir just until moistened; batter will be slightly lumpy.
Preheat waffle iron and spray with nonstick spray. Pour batter into waffle iron grid and close the lid. Bake until waffles are done. Use a fork to remove finished waffles. Repeat with remaining batter. Keep waffles warm until ready to serve (a 200 degree oven).
For cinnamon topping: In a medium bowl, mix butter, brown sugar and cinnamon. Scoop the filling into a small zip baggie and set aside.
For cream cheese glaze: In a medium, microwave-safe bowl heat butter and cream cheese for 30 to 60 seconds; just until melted. Stir together until smooth; whisk in powdered sugar and vanilla extract.
Place waffle on plate, drizzle cinnamon topping and cream cheese glaze. Serve and enjoy!
