Preheat the oven to 180C. Grease a donut baking tray and set aside.
In a large bowl, combine all of the wet ingredients. Then, add the wet ingredients and stir until combined.
Transfer the batter into a small milk jug and pour into the donut tray, dividing it evenly between the 6 donut wells.
Bake in the middle of the oven for 15 minutes or until a skewer inserted to the centre comes out clean.
Cool for 5 minutes before transferring onto a cooling rack. Cool completely before decorating.
To decorate the donuts, transfer the chocolate spread into a small bowl or a plate. Microwave until runny. Dip each donut into the melted choc spread then carefully lift the donut back out. Sprinkle with chopped roasted hazelnuts. Repeat with all 6 donuts. Leave to set for 5-10 minutes. Enjoy!
