Add all ingredients to a blender and blend until smooth.
Preheat your waffle maker.
Pour the batter into your waffle maker and cook according to your model (this makes 3-4 large Belgian style waffles). We use the GreenPan on the waffle setting, level 4, for 6 minutes.
Allow to cool slightly before serving.
Store in the fridge for 3 days or freezer for 2 months. To freeze: Lay the cooked waffles flat on a baking tray and freeze for 1 hour. Transfer to a bread bag or airtight container and store in the freezer. Reheat straight from frozen in the toaster.
