Combine the egg powder with the water.
Mix the flour and spices, then add the oat milk and egg powder mixture. Combine well, stir in the oil and rest. (The batter should be a bit thicker than a normal pancake batter)
Peel the pear, discard the core, then cut it into small chunks. Put these in a non-stick small frying pan, add a drop of lemon juice and half of apple juice, then a the sugar and spices. Cook for about 5 minutes until the pear pieces get caramelised but they are still tender. Turn off the heat and keep the mixture warm under a lid.
Heat the waffle maker and spray with oil, if needed. When it’s hot, add a ladleful of the batter and seal. Cook the waffles until they are golden and crispy, following the machine’s instruction. It should take about 3-5 minutes per waffle, depending on your waffle maker.
Transfer the waffle to a plate, then make more (you should get another 2 or 3 waffles depending on the size of your machine).
Serve the waffles with the caramelized pear and maple syrup drizzled on top.
