Optional, for serving: butter, syrup, fresh berries, whipped cream
Instructions
In a large bowl, whisk together the Bisquick, egg, club soda, and oil. Don't over-mix the batter. Stir just until the ingredients are combined. You will still have some lumps, which is fine. Let the batter rest while you preheat the waffle iron.
Cook the waffles in a lightly oiled waffle iron for 3-5 minutes each, or until cooked through and golden brown.
Notes
Keep the waffles warm while you finish the remaining batches by placing the cooked waffles on a wire rack on top of a rimmed baking sheet in a 200° F oven.If you don't have Bisquick, this recipe will likely work with other all-purpose baking mixes. I have tested it with good results using Krusteaz mix, but I haven't tried any other brands. Let me know if you have success with other varieties as well!
