In a small bowl coat the apple in the CINNAMON SYRUP and lemon juice.
Add chopped apple to a lightly greased bowl or ramekin.
Take your apple mixture and microwave on high for one - two minutes to soften (this speeds up the cooking time but if no microwave, bake for an extra 10 minutes).
In a separate bowl, add the oats, non-dairy butter and CINNAMON SYRUP and mix it all together with your fingers until all ingredients are well incorporated.
Put the oat mixture on top of the apples.
Bake for approximately 6 - 10 minutes or until the highest peaks of the crumble start to turn a light brown colour.
Serve with custard and an extra drizzle of CINNAMON SYRUP
