Preheat the oven to 180°C on a fan forced setting and lightly grease a donut tray.
Add the pumpkin mash, maple syrup, almond milk, butter and vanilla to a blender or food processor and blitz until smooth.
Transfer into a large bowl and sift in the flour and cinnamon. Mix ingredients together until it resembles a thick cake batter.
Pour mixture into the donut tin, filling them ¾ of the way.
Place the tray in the oven and bake for 10-12 minutes, until a skewer comes out clean.
Mix the cinnamon and coconut sugar together on a plate.
Once the donuts are cooked, allow them to cool slightly. Then, toss in the cinnamon coating and serve.
