Combine all ingredients together in a mixing bowl (except flour and cornstarch). Add flour and cornstarch and whisk until evenly mixed. It is fine to have a few small lumps.

Cover mixing bowl with plastic wrap and leave in the refrigerator overnight.

The next day, remove mixing bowl from refrigerator and allow waffle batter to cool to room temperature. Heat the waffle iron, and spray with oil spray or brush with butter once the waffle iron is hot. Ladle some batter onto waffle iron, and cook waffle for about 4-5 minutes and waffle is crispy and brown.

Remove waffle from waffle iron and serve with honey and butter. If not serving immediately, keep warm in a 90°C oven to maintain crispiness of waffle.
