To make the crepes simply put all dry ingredients into a bowl and stir with a whisk.
Process all wet ingredients (except the oil) in a food processor or blender.
Pour the wet ingredients into the bowl of dry ingredients and stir with a whisk to combine.
Let the batter rest for a few minutes. Heat a little oil in a small/medium-sized non-stick skillet over medium heat.
Pour 1/4 cup of the batter into the skillet, and spread it with the back of a ladle. Cook for about 2-4 minutes or until you can easily lift a side of the crepe (don't try to flip the crepe too early). After you flipped the crepe, cook for a further 1-2 minutes.
Note: After a while, the batter will get thicker, so you might need to add more milk. I typically add up to 50 ml in addition once the batter thickens. Continue until you have no batter left.
For the apple filling, simply add all ingredients to a skillet or saucepan and stir (without heat). Then turn on the heat and bring the mixture to a boil. Let simmer for a few minutes over low/medium heat.
Place a few tsp of filling onto each crepe, roll it up and serve with a drizzle of caramel sauce (see recipe below in the notes). Enjoy!
