In a mixing bowl, combine lukewarm water, milk, 1 tablespoon of flour, 1 tablespoon of sugar, and dry yeast. Mix well and let it sit in a warm area for 10 minutes until it gets bubbly and frothy.

In a separate bowl, mix the remaining flour and a pinch of salt. Gradually add the butter, using your hands to crumble the mixture until it resembles sand.

Add the sugar, egg, and the yeast mixture to the flour mix. Knead the ingredients together for about 5 minutes until you have a smooth dough.

Lightly dust a clean work surface with flour, and place the dough on it. Knead for an additional 5 to 8 minutes until the dough springs back when poked.

Lightly oil a clean bowl and place the dough inside, oiling the dough’s surface as well. Cover the bowl with a clean cloth or plastic wrap and let it rise at room temperature for about an hour or until it doubles in size.

After proofing, divide the dough into four equal parts and shape them into balls. Roll out each ball into a sheet that is about 1/2 inch thick and cut out the donuts.

Cover the donuts with a cloth and let them rise again for another 30 to 40 minutes.

Heat oil in a pan to around 375 degrees F. Fry the donuts for about 70 to 90 seconds on each side until golden brown. Drain them on a cooling rack.

To prepare the glaze, mix lukewarm milk, confectionary sugar, heavy cream, and vanilla in a bowl. Glaze the donuts by either piping or dipping them in the icing.

Serve and enjoy the fluffiest donuts!
