Preheat the Belgian waffle maker. If using the Sage waffle maker, use the Classic setting and choose your preferred browning setting.
In a medium sized bowl, mix the wet ingredients; eggs, milk, melted butter, vanilla extract.
In another bowl, sift the gluten free flour, spice and combine with the caster sugar.
Make a well in the dry ingredients and pouring in the wet ingredients, mix into a batter making sure the largest lumps are mixed in. A few small lumps are okay.
Using a ladle, pour the batter into each compartment of the waffle maker. Beware not to overfill. Close the lid and cook for around 4 minutes - or however long the built in timer suggests.
Serve waffles immediately with a topping of melted chocolate, banana slices and speculoos biscuit crumbs.
