In a small bowl add the milk and lemon juice, stir and set aside for 5-7 minutes and allow to curdle.
Once curdled add the milk-lemon juice mixture into a large bowl, add melted butter and vanilla. Using whisk mix until nicely incorporated.
To the wet ingredients add oat flour and baking powder. Using a spatula mix this well.
Add hot water to the right batter consistency, whisk this until a smooth batter is achieved. Let the batter rest for 10 minutes.
Grease the waffle maker with oil, using an ice cream scoop, transfer 2-3 scoop-fuls of the batter in the middle and close the waffle maker. Allow the waffles to cook, open the waffle maker and carefully lift the hot waffle out onto a plate.
Dress your waffle with banana and a generous drizzle of maple and dig right in!
