Preheat an oven to 190C.

Lightly grease a doughnut baking tray.

Mix the baking powder with the pancake mix then add the wet ingredients and shake so everything is combined, and you have a thick but runny batter. Pour or spoon this into the doughnut moulds, ¾ full then bake for 12-15 minutes, until golden.

Carefully tip the doughnuts out onto a cooling rack and repeat with more mix. Allow the doughnuts to completely cool before icing them. The bottom of the doughnut becomes the top to dip in the icing,

For the icing sugar, mix all the ingredients together to a smooth, thick icing,

Using your fingers or tongs, dip the doughnuts into the icing to coat the top side of the doughnut then place back onto the cooling rack icing side up.

Finely shave the pistachio nuts and orange zest and sprinkle over the doughnuts.

Alternatively, decorate with anything you want.
