Pre-heat the oven to 160 °C (fan) or 180 °C (conventional)
In a mixing bowl, add in all of the doughnut ingredients (except the vegan white chocolate) and mix together
Once the ingredients have combined, whisk the mixture until it becomes light and airy
Use a piping bag or a spoon to place the batter evenly into the doughnut moulds
Bake for 20-22 minutes
Remove from the oven and leave to cool completely in the mould
To decorate, melt the white chocolate using either a Bain-Marie or microwave (10 second bursts, stirring intermittently)
Place the top of the doughnut into the bowl containing the chocolate and coat, shaking off any excess
Invert the doughnut (chocolate side should be on top) and shake slightly so the chocolate evens out
Leave to set and then enjoy!
