Preheat your oven to 180 degrees (fan-forced) and line the base and sides of a large loaf tin with baking paper.
Peel the apple and roughly chop it into pieces no bigger than 1cm. Place the apple pieces into a small bowl and add the cinnamon before gently stirring to combine. Set aside until needed.
Place the self raising flour, caster sugar, butter, vanilla extract, eggs and milk into your Thermomix bowl and mix for 15 seconds, speed 5.
Scrape down the sides of the bowl and mix for a further 10 seconds, speed 4 or until the mixture is smooth and well combined.
Pour the mixture into your prepared loaf tin and sprinkle the apple pieces over the top.
Place the Apple Loaf into your oven and bake for 50 - 55 minutes or until cooked when tested with a skewer. Carefully remove your Apple and Cinnamon Loaf from the oven and allow it to cool in the loaf tin for 10 minutes before transferring to a wire rack to cool completely.
