Bomboloni (Italian Cream‑Filled Donuts)

Bomboloni are soft, pillowy Italian donuts rolled in sugar and filled with rich pastry cream. When you bite into one, the vanilla cream filling bursts out like a sweet explosion. Wonderfully delicious when eaten warm for breakfast just like Cinnamon Sugar Fried Apple Rings or Strawberry Donuts.

I first tasted Italian donuts in Erice, a quiet hilltop town in Sicily, at a tiny convent where only the nuns know the secret recipe. They were warm, sugar-dusted, and impossibly soft-we even considered canceling the rest of our trip just to have them again.

Originally from Tuscany and popular in northern Italy, you can find these cute doughnuts all over Italy today. Just pop into any Italian bar or pasticceria (an Italian bakery) in the morning anywhere in Italy and there's a good chance you'll find bomboloni there!

What Are Bomboloni

Bomboloni are small, round Italian bakery-style donuts at home, made from a buttery, yeasted dough, fried until golden, rolled in sugar, and filled with pastry cream. They resemble jelly donuts but stand out because the pastry filling is visible and generously piped.

The name comes from bomba which means "bomb" in Italian and bomboloni truly look like explosive bombs of sweetness. These traditional Italian pastries are round, plump and stuffed with explosive filling that just bursts in your mouth.

Bomboloni vs. Jelly Donuts

Bomboloni wins on texture (airier, cloudier dough) and filling generosity, while the Jelly Donut wins on being quicker, simpler dough.

• Bomboloni walks in: "We're not enemies. We're cousins. But I am the fancier cousin."
• Jelly Donut sighs: "...Fine. Your filling ratio IS more generous. And that airy texture is kinda unfair."

Why You'll Love Bomboloni

• Traditional Italian Breakfast Pastry: Bomboloni are deeply rooted in Italian café and bakery culture, often enjoyed with morning coffee or as an afternoon treat. Truly an authentic Italian dessert recipe, just like Italian Apple Bundt Cake.
• Use any filling you like: Silky pastry cream, custard, Nutella, or jam. Keep in mind that unlike regular doughnuts that sometimes skimp on filling, Italian donuts are generously stuffed.
• The sugar coating: After frying, they're rolled in sugar, so the outside is slightly crunchy and sweet. That mix of crisp sugar outside and soft fluffy inside? Pure magic.

Ingredients for Bomboloni Dough

• Flour: It's what everything else holds together with (unbleached flour is best). Think of it as the framework for your dough. You can use Italian 00 flour or all-purpose flour.
• Sugar: Gives sweetness and helps the dough brown nicely. Also feeds the yeast a little bit, helping the dough rise.
• Yeast: Instant yeast is what makes the dough puff up, become airy and soft. Without it, you'd just have dense fried dough. Yeast is what makes bomboloni soft, fluffy, and slightly chewy. Imagine biting into a little warm bread that's been fried until golden and lightly crisp on the outside. It's not heavy or greasy at all.
• Milk: Adds moisture and flavor. Makes the dough richer and softer. Warmish milk is better so the yeast works well.
• Eggs: They might seem like a simple ingredient, but eggs are a really important part of making bomboloni. Think of eggs as the glue and the magic that holds your dough together. They also add moisture to the dough, which keeps your bomboloni soft and fluffy on the inside. 
• Butter: Adds fat which gives flavor and makes the dough softer and more luxurious to eat.
• Salt: Balances the sweetness and brings out all the flavors-you don't want bomboloni bland.
• Sunflower oil: Frying in oil gives that golden crust on the outside and soft inside. You'll need enough to submerge the bomboloni.

Ingredients for Pastry Cream Filling

• Vanilla extract: The vanilla cream filling is what makes the difference
• Egg yolks and cornstarch: Both of these prevent the pastry cream for the bomboloni filling from becoming too runny or separating.

How to Make Bomboloni Step by Step

Below is an overview of the process with extra tips for getting fluffy, evenly fried bomboloni. For exact measurements and times, see the full recipe card at the bottom of the post.

1. Activate the yeast

Warm the milk until it's just lukewarm, about 100-110°F; it should feel warm but not hot on your finger. Sprinkle the yeast over the top, stir, and let it sit until foamy-if it doesn't foam after 5-10 minutes, the yeast may be inactive and it's better to start again than risk dense donuts.

2. Mix and knead the dough

Add the flour, sugar, and salt to the bowl of a stand mixer and whisk to combine, then pour in the milk‑yeast mixture, eggs, and oil.

Start mixing on low, then increase to medium‑low and knead until the dough is smooth, elastic, and only slightly sticky; add extra flour a little at a time only if the dough stays very wet and refuses to pull away from the sides of the bowl.

The dough should feel soft and stretchy rather than dry-this is key for light, airy bomboloni.

Step 3. First rise (bulk proof)

Shape the dough into a smooth ball and place it in a lightly greased bowl, then cover and let it rise in a warm, draft‑free spot until doubled in size. Instead of watching the clock, look for volume: rich doughs can take 60-90 minutes or more, and under‑proofed dough will make heavy donuts.

Step 4. Make the pastry cream

While the dough rises, cook the pastry cream so it has time to chill and thicken before filling.

1. Gently heat the milk, whisk the sugar, cornstarch, and salt with the egg yolks, then slowly temper with hot milk so the eggs don't scramble.
2. Cook over low heat, whisking constantly, until the mixture is thick like pudding, then stir in vanilla.
3. Cover the surface with plastic wrap, and chill until cold and set; cold cream pipes more cleanly and won't soak into the dough.

Step 5. Roll and cut the bomboloni

1. Turn the risen dough out onto a lightly floured surface and roll it to about ½‑inch thickness.
2. Cut out rounds with a 2‑inch cutter and arrange them on a parchment‑lined baking sheet, leaving a little space between each one.

Try not to re‑roll the scraps more than once so the dough doesn't get tough; any odd pieces can be fried as "tester" donuts.

Step 6. Second rise

Cover the dough rounds lightly with plastic wrap and let them rise again until very puffy and light. A gentle finger press should leave an indentation that slowly springs back-if it pops right back, they need more time; if they collapse, they're over‑proofed and may fry up flat.

Step 7. Fry the bomboloni

1. Heat about 2 inches of neutral oil to 350 degrees in a dutch oven or frying pan. 
2. Carefully place as many rolls that will fit in your dutch oven or pan without overcrowding and fry them until golden brown on both sides, about 3 -4 minutes for each batch. 
3. Place your bomboloni on a cooling rack (inside your cooking sheet so that they are raised above it and so that any oil can drip off) after they are fried.

Step 8. Coat in sugar

While the bomboloni are still warm, roll them in granulated sugar so it sticks to the surface. If they cool completely first, the sugar won't adhere as well; you can always give them a light second roll just before serving.  

Step 8. Fill with pastry cream

Once the donuts are cool enough to handle, spoon the chilled pastry cream into a piping bag fitted with a small round tip.

Insert the tip into the top or side of each bomboloni and gently wiggle it to create a pocket, then pipe in the filling in short bursts until the donut feels full but not bursting-overfilling can cause leaks. You should see a little cream peeking out of the opening for that classic bakery look.

Expert Tips for Light, Fluffy Bomboloni

• Build a strong, soft dough. A good bomboloni dough should be smooth, elastic, and slightly tacky; it should stretch without tearing after kneading. So knead long enough (stand mixer or by hand) for the dough to clean the bowl and form a soft, cohesive ball.
• Add softened butter after the dough has started to come together rather than at the very beginning; this helps gluten form before the fat coats the flour. Use finely milled flour (Italian 00 or all-purpose) and warm, not hot, milk so yeast stays active without being damaged.
• Control dough temperature and proofing. Bomboloni dough performs best in a warm but not hot environment. Aim for a noticeable rise-often around 30-100% during bulk-rather than relying strictly on a clock, adjusting for room temperature and dough richness.
• For the second rise, shaped doughnuts should become very puffy and light, often proofed around 30-60 minutes in a warm, draft-free spot. A gentle finger press that slowly springs back is a better indicator than time alone; underproofed bomboloni are dense, while overproofed ones may collapse or soak up oil.
• Handle dough gently after proofing. Once shaped dough has proofed, treat each bomboloni like a delicate bubble-avoid pressing, stretching, or shaking them. Transferring them via parchment and lowering them slowly into the oil preserves their structure and prevents deflation.
• To prevent dense bomboloni. Even small pokes can knock out gas and lead to flatter, denser doughnuts, so reserve any poking or testing for earlier in the proof.
• Fry in small batches so the oil temperature does not drop too much when you add the dough, and give each side about 2-4 minutes, depending on size, until deep golden with a pale "fry line" around the middle. Use a slotted spoon or spider to turn them gently to avoid tearing the crust and losing volume.
• Cooling time and filling consistency matters: Classic pastry cream should be cooked until thick enough to hold soft peaks, then chilled until firm before piping into bomboloni. If the cream is too loose, it will soak into the crumb or leak.
• To avoid overfilling and blowouts, simply create a proper internal pocket by gently wiggling the tip inside and adding filling in short bursts, pausing to feel the doughnut expand.
• To prevent greasy or dense bomboloni, always preheat the oil fully, let the dough sit at room temperature after any refrigerator rest, and avoid letting the second rise go far beyond the point where dough feels light and jiggly. 
• Be patient about adding flour and not add too much flour at once and allow the mixer to do its job. You may need to add about ½-¾ cup of flour to achieve the consistency I wanted in the dough, that soft and just sticky surface.  
• Pastry cream tips: With pastry creams I have found that you really need to watch your milk, possibly rewarming it a little after tempering so that it's at that low bubble stage before adding the tempered mixture.  Otherwise it can take a long time to cook and you lose some of the thickening capability of the eggs.  
• Keep an eye on the oil temperature: Frying oil can be hard to control on a stove top which may result in a darker fry. I kept testing the heat as I added each batch. 
• Donuts should still be warm when rolling it in the sugar so it sticks.

FAQ

• Why are my bomboloni oily? Bomboloni turn oily when the frying oil is too cool, the dough is under- or over-proofed, or the donuts sit too long in the oil. Keep oil in the 350-355°F range and fry just until golden, then drain on a rack or paper towel.
• Why are my bomboloni dense instead of fluffy? Dense bomboloni usually mean the dough didn't proof long enough, the yeast was weak, or too much flour was added, making the dough heavy. Let the dough double in size, handle it gently after shaping, and roll to about ½ inch thickness so it can puff while frying.
• Can I make my Bomboloni dough by hand? Yes, you can make your dough by hand.  Bring your dough together with a wooden spoon in a bowl until all the ingredients come together in a soft dough ball.  Roll out onto a generously floured counter and knead for 6-8 minutes until the dough is soft and just slightly sticky to the touch.  
• Why do I have to proof the dough a second time? Proofing the dough after you have cut into 2" rounds allows the dough to spring back before frying and gives you that light and airy donut.  
• Why do I have to "temper" my eggs before adding them to the saucepan? If you don't "temper" (bring up the temperature of the eggs) and you add them directly to your hot milk, you will more than likely create scrambled eggs in milk rather than a smooth pastry cream. 
• Can I bake bomboloni instead of frying? Yes, but "baked bomboloni"will be lighter and less rich than the original fried version but still soft. For baked version, add the filling before baking or use a piping bag once the doughnuts are cooled.
• What fillings work best for bomboloni? Rich, thick fillings like pastry cream, Italian custard, chocolate cream, Nutella, pistachio cream, or jam hold up well without leaking. Chill the filling slightly and use a long piping tip to fill from the side or top for that signature, overstuffed bomboloni look.
• How long do bomboloni stay fresh and can I freeze them?Bomboloni taste best on the day they're made, especially when freshly fried and filled.
• What oil is best for bomboloni? Use neutral vegetable or sunflower oil so the flavor stays clean and light.
• What temperature should the oil be? Keep it around 340-350°F (170-175°C) for standard yeasted bomboloni.
• Do bomboloni have to be filled? No; you can serve them plain, sugared, or with a small dollop of filling on top instead of inside.

Common Bomboloni Problems and Fixes

• Doughnuts too dense: This usually indicates under-proofing, weak yeast, or not enough kneading to develop gluten; ensure the dough doubles fully during both rises.
• Greasy or pale exterior: Oil that is too cool causes bomboloni to absorb excess oil and fail to brown properly; aim for the 340-350°F range and let the oil return to temperature between batches.
• Dark outside, raw inside: Oil that is too hot browns the exterior before the center cooks; lower the heat and stay within the recommended temperature range.
• Filling leaking out: Overfilling or making too large a slit in the doughnut can cause cream to escape; use a small tip, insert it deeply, and stop piping when the doughnut feels nicely full but not bursting.

How to Move Bomboloni without Deflating Them

• Proof each bombolone on its own small square of parchment paper so you never have to touch the dough directly. When ready to fry, lift the parchment by the corners and lower the bombolone into the hot oil parchment-side down; the paper will release and float off so you can pull it out with tongs. Transfer them in one smooth motion as close to the oil as is safely possible so they don't "drop" and collapse.
• Proof on lightly greased or lightly floured parchment so bomboloni release easily instead of sticking and tearing as you move them.
• If you move bomboloni by hand, slide fingers under the edges instead of pressing down on the top, and avoid lifting them high or stretching the dough.
• If the dough feels so fragile that it collapses when moved, it is likely over-proofed; shorten the proofing time next round so they're airy but still strong enough to lift.

Bomboloni Filling Ideas

• Swap classic pastry cream for Nutella, chocolate-hazelnut spread, pistachio cream, vanilla custard, or any thick jam (like sour cherry or raspberry) for jam-filled Italian donuts.
• If you like a little fluffier and lighter pastry cream, fold in some whipped topping into it before piping (it's an option to the recipe).
• Further, if your pastry cream doesn't turn out thick enough this is a great save to add some whipped topping. 

Serving suggestions

• Serve bomboloni warm right after frying for the best texture and flavor experience, with the vanilla cream filling still gooey inside.
• Pair with a strong espresso or cappuccino for a traditional Italian breakfast or brunch.
• Enjoy these soft Italian donuts with a hot tea or a glass of cold milk for brunch or as a snack.
• Dust with extra powdered sugar or drizzle with melted chocolate or caramel sauce for a decadent dessert.

Substitutions and Variations

• Flour substitutions: Use all-purpose flour instead of Italian 00 if that's what you have; both work well for soft, airy doughnuts when hydrated and kneaded properly.
• To make bomboloni light: For a lighter option, whole milk can be swapped with a similar-fat plant milk in vegan recipes, and butter with a neutral vegetable oil, as long as the flavor is mild.
• For egg-free bomboloni, use an enriched, eggless sweet-dough formula or a tested eggless bomboloni recipe, keeping the same proofing and frying guidelines.
• Frying oil substitutions: Use neutral, high-smoke-point oils like sunflower, canola, peanut, or vegetable oil; avoid strongly flavored or low-smoke-point oils such as olive oil.

How to Store and Freeze Bomboloni

• Can I make them ahead? You can prepare the dough and let it rise in the fridge overnight, then shape, proof, and fry the next day for fresher results.
• Unfilled bomboloni can be stored at room temperature in an airtight container for about a day, though they are always best the same day. Once filled with cream, they should be stored in the refrigerator and eaten within 1-2 days for food safety and best texture.
• Dusted bomboloni: Store in plastic container, not a bag because these donuts can get "watery" from the sugar if they are stored in a bag. I stored them in a plastic container and they did better. 
• Freeze undusted Bomboloni for up to 6 months. Place each filled donut on the parchment paper covered cooking sheet and place in the freezer. Once frozen, pack frozen bomboloni inside a resealable bag and store in the freezer.
