Frying Ingredients
1potVegetable oilFor frying; enough for a pot depth of 3–4 inches

Instructions
In a large bowl or in the bowl of a stand mixer fitted with a dough hook, whisk together flour, yeast, salt, sugar, and lemon zest until evenly combined.
Add eggs, warmed milk, butter, and vanilla extract to the dry ingredients. Mix until a shaggy dough forms.
Knead the dough for 6–8 minutes until smooth and slightly sticky. If too sticky, add flour a teaspoon at a time.
Transfer the dough to a lightly oiled bowl, cover, and let rise in a warm place for about 1 hour, until doubled in size.
Punch down the dough and roll it to about 3/4-inch thickness. Cut rounds and place on parchment-lined baking sheets.
Cover the rounds and let them rise again for about 1 hour until puffy.
Heat vegetable oil to 350°F. Fry bomboloni in batches for 4–5 minutes until golden brown.
Remove and drain on paper towels. Roll in granulated sugar while warm.
Fill with chocolate-hazelnut spread, jam, or pastry cream using a piping bag.
Notes
For lighter bomboloni, avoid adding too much flour when rolling. You can also bake them at 375°F for a lighter option.
