To make the doughnuts cream the butter with the sugar until paler in colour
Add all the remaining ingredients and beat for around 1 minute until well mixed
Place the mixture into a piping bag (or sandwich bag with corner snipped off) with a small round nozzle attached
Pipe the mixture into non-stick doughnut trays making sure not to put too much mixture into each section or the hole in the middle with disappear when they rise in the oven
Bake in a pre-heated oven at 180 degrees/160 degree fan for approx. 7 minutes until springy to the touch
Whilst the doughnuts are baking make the topping by heating the ingredients together until melted
Once the doughnuts have cooled, dip them in the warm chocolate topping and add sprinkles if you fancy
