Combine all the wet ingredients in a large mixing bowl and whisk until thoroughly combined. Combine all the dry ingredients in a separate bowl and stir until combined.
Add the dry mixture to the wet mixture and stir just until combined. A few little lumps are okay - do not over-stir. Let the batter rest for 10 minutes and then give it another gentle stir. Preheat your waffle maker during the final minutes of the batter's resting period.
Cook the waffles until golden and lightly crispy. Don't stack the waffles or they will become soft. If you're making more than four waffles, keep the waffles warm by placing them single-layer in the oven heated to 200 degrees F.
Serve the waffles immediately so they remain crispy. Serve with some butter, maple syrup and a light sprinkling of cinnamon.
