Instructions
In a large mixing bowl, combine the warm milk and instant yeast. Let it sit for about 5 minutes until the yeast becomes frothy.
Add the granulated sugar, melted butter, and the egg to the yeast mixture, whisking to combine.
In another bowl, whisk together the all-purpose flour and salt. Gradually add the dry mixture to the wet ingredients, stirring until a rough dough forms.
Transfer the dough onto a lightly floured surface and knead it for about 8-10 minutes until smooth and elastic.
Place the kneaded dough in a greased bowl, cover, and let it rise in a warm place for about 1 to 1.5 hours until doubled in size.
Punch down the dough, roll it out to 1/2-inch thickness, and cut out donut shapes.
Place the cut-out donuts on parchment paper, cover loosely, and let them rise for another 30-40 minutes.
Heat oil in a deep skillet or pot over medium heat to about 350°F (175°C).
Carefully lower the donuts into the hot oil, frying for 1-2 minutes on each side until golden brown.
Once cooled slightly, use a piping bag to inject Nutella into the center of each donut.
Dust the filled donuts with powdered sugar before serving.
Notes
Store leftover donuts in an airtight container at room temperature for up to two days.
