Step 1

Mix sugar and vanilla extract in a bowl. Spread on a baking sheet to dry for 1 hour. Break clumps and transfer to a brown paper bag.

Step 2

Make the Zeppoli Dough:

Step 3

Sift together flour, baking powder, salt, and sugar in a large bowl. In a separate bowl, whisk together egg yolks, milk, melted butter, and vanilla. Gradually mix wet ingredients into dry ingredients until just combined. Knead briefly to form a smooth, stiff dough.

Step 4

Turn the dough onto a lightly floured surface. Roll out to about 1/2 inch thickness. Cut the dough into rectangles, approximately 3 inches in length. Use a fork or toothpick to poke holes evenly across the surface of each zeppoli.

Step 5

Heat oil in a deep fryer or large pot to 375°F (190°C). Check the temperature with a candy thermometer.

Step 6

Carefully place the docked dough rectangles into the hot oil. Fry for 2-3 minutes on each side until they puff up and turn golden brown. Do not overcrowd the pot. Transfer the zeppoli to a plate lined with paper towels to drain excess oil.

Step 7

While the zeppoli are still warm, place them in the brown paper bag with vanilla sugar. Close the bag and shake gently to coat evenly.

Step 8

Prepare the Chocolate Sauce (optional): Heat the heavy cream in a saucepan until it simmers. Remove from heat, add chocolate chips, and stir until smooth and well combined.

Step 9

Serve the vanilla sugar-coated zeppoli with chocolate sauce for dipping.
