Potato Doughnuts

Ingredients:

500g bread flour
50g powdered milk
11g dry yeast
200g mashed potato
100g caster sugar
75g unsalted butter (room temperature)
1/2 tsp salt
4 egg yolks
100ml cold water

How to:

In a mixing bowl, place flour,sugar, salt, milk and yeast. Mix. Then add mashed potato, egg yolks and cold water. Knead until half smooth.
Lastly add butter and knead some more until nice and smooth. And let it rest for 15 minutes.
Divide the dough, weigh 50g each. Or you can also do what I did, I flatten the dough and then use my round cutters to make them. Up to you.
Let it rest for 20 minutes again.
Deep fry them in hot oil (170° C) until golden brown (around 30 seconds on each side).
Once cooled, you can dip them in sugar-cinnamon mix or just icing sugar or top with chocolate and other toppings.
