Donuts filled with Italian diplomatic cream

Meanwhile, prepare the Italian diplomat cream
by mixing the pastry cream with the liquid cream whipped with the two tablespoons of icing sugar.

Pour the oil into a saucepan with high edges and,
once very hot, plunge the donuts (no more than 2 at a time)
so as not to lower the temperature of the oil.

Let rise and brown for 5 to 6 minutes per donut.
