Proof yeast: In a small bowl, add milk, stir in yeast and sprinkle some sugar over it. Set aside until it's foamy.

In another bowl, add flour, sugar, salt, and stir.

Add the melted butter, egg, and mix. You can do this process with your standing mixer or hand.

Add the yeast mixture and combine until it is smooth. Sprinkle some flour if it's too sticky, I added about one tablespoon.

Grease a bowl, and add the dough. Cover and place in a warm place to rise (double in size).

After it has risen, place the dough on a floured surface and punch down. Divide the dough into two and work with one at a time.

Roll the dough to about 1/4''-1/2'' thickness.

Place parchment on baking sheets sprinkle flour over the baking sheet and set aside.

Dip a cutter into a flour (to avoid sticking) and cut out the dough. 

Place the cut-out dough on the baking sheet leaving some space apart in between the doughs. Cover and let the dough rises (doubled) again.

Heat oil in a fryer or dutch, let the oil heat to about 350-375 degrees F. Fry the dough (don't overcrowd the oil) for about 2 minutes on each side.

Be careful when picking the dough up in other not to deflate.

Drain on the paper towel tray. Squeeze in some jelly into the donut (one at a time) you can use a piping tip and bag.

Coat the donut with sugar (as much as you want it), let it cool down and enjoy!
