Prepare the Yeast Mixture: In a bowl, combine the milk, yeast, and a teaspoon of sugar. Mix and let it sit for 10 minutes.
Using a Stand Mixer: Add the flour, beaten egg, melted butter, sugar, and the milk-yeast mixture to the mixer’s bowl. Beat the dough for 20 minutes until soft and elastic.
By Hand: Combine butter, egg, sugar, and salt in a bowl. Add milk with yeast and flour. Transfer to a lightly floured surface and knead until smooth. Let the dough rise in a covered bowl until doubled in size, ideally in a turned-off oven with the light on.
Shape the Donuts: Roll out the dough into a rectangle about half a centimeter thick. Cut out 6cm discs using a cookie cutter. Place them on a baking sheet with a square of baking paper under each donut. Let them rise for another hour.
Prepare the Cream: Mix the pastry cream with the whipped liquid cream and icing sugar.
Frying the Donuts: Heat oil in a saucepan. Fry the donuts, a few at a time, for 5-6 minutes each until golden brown.
Fill the Donuts: Once cooled, fill the donuts with the Italian Diplomatic Cream using a piping bag.
Enjoy these delightful Italian Cream-Filled Donuts, a perfect treat for any occasion. Their sweet, creamy filling and soft dough make them a sure hit for anyone craving a little indulgence.
