These waffles took between 4½-5 minutes to cook ½ cup batter in each slot of my Breville Waffle Maker (using custom setting). Once waffles stop steaming (or almost), they're most likely done. Should be golden brown and crispy on the outside.
Transfer waffles to a cooling rack or baking sheet. Don’t stack waffles on top of each other or they’ll lose their crispness. As an option, keep warm by placing in a 200°F oven until you’re ready to serve.
Be sure to select pure maple syrup to ensure it's gluten free.
