Preheat the oven to 180 degrees celsius
In a medium bowl whisk together the apple sauce, egg, milk, oil and cinnamon
Stir in the flour, mix lightly with a wooden spoon until just combined
Gently stir through the grated apple
Portion into a mini muffin tin (I get 16 mini muffins from this recipe) I use a silicone muffin tray
Bake for approximately 15 minutes
Allow to cool in the tin until cool enough to handle, remove from the tin and cool on a rack
Store in an airtight container for three days, or freeze for up to 3 months
