Make the Dough

Proof the yeast. In a large bowl or the bowl of a stand mixer, combine the warm (not hot) milk, yeast and sugar. Let this mixture stand for a couple minutes.

Make the dough. Add the vanilla extract, eggs, 1/4 cup olive oil, and salt, and mix well. Add the bread flour and combine with a wooden spoon or with the paddle attachment of your mixer. Add the remaining all-purpose flour 1/2 cup at a time until the dough starts to form a ball and pulls away from the sides of your bowl.

Knead the dough. Turn the dough out onto a well-floured surface or switch to your dough hook. Knead the dough for 4-5 minutes, dusting with flour occasionally to prevent sticking, until you have a smooth, firm dough that bounces back when pressed with your thumb.

Allow to rise. Grease a large bowl with the remaining 1 teaspoon of olive oil. Put your dough in the bowl, turning once to coat. Cover with saran wrap and allow the dough to rise for 1 hour.

Heat the oil. In a large Dutch oven or heavy-duty pot, heat 5 inches of vegetable oil to 345F – 350F degrees F. (Use a candy thermometer attached to the side of the pot to judge the temperature. Dutch ovens are best since they regulate the temperature better than regular pots.) Keep an eye on the temperature and adjust the heat of your stove accordingly. You don’t want to temperature to rise above 350F or the beignets will burn. Likewise, you don’t want the temperature to drop below 345F or the beignets will not cook through.

Form the Beignets

Roll out and cut the dough. While the oil is heating roll out your dough on a lightly floured surface until it is about 18 x 15 inches. With a pizza cutter or a sharp knife, cut the dough into 3 x 5 inch rectangles.

Fill and shape the beignets. Using a teaspoon measure, place a ball of Nutella on one side of each rectangle. Center the Nutella in the middle of that side. Wet your fingers with a small amount of water, and then run them along one side of the rectangle. Fold the dough over the Nutella, pressing gently so that air doesn’t get trapped inside. Seal the dough by pressing the edges together with the tines of a fork.

Fry the Beignets

Fry until golden. When the oil reaches 345 – 350 degrees F, fry the beignets, two or three at a time. Fry until the underside is a deep golden brown, about 1 minute. Turn the dough over and fry until that side is golden brown. Keep an eye on the temperature and adjust the heat as you go.

Drain. When finished remove the beignets from the oil with a slotted spoon and allow them to drain on a plate lined with paper towels.

Add sugar and serve! Dust with a generous amount of confectioners sugar and serve immediately.
