Bakery-Style Bomboloni Doughnuts

The first bite of a bombolone should crackle with sugar, then give way to a soft, airy center and a generous ribbon of vanilla cream. These Italian doughnuts turn that bakery-window moment into a dessert you can make at home, with enough hands-on detail to feel special without becoming fussy.

Traditional bomboloni depend on wheat flour, regular milk, and butter. This version uses a measured blend of rice flour and starches, dairy-free baking sticks, and lactose-free milk to create a gluten-free, lactose-free doughnut made with Low-FODMAP-friendly ingredients.

Set aside an unhurried afternoon, let the dough rise until visibly puffy, and keep the oil temperature steady while you fry. The reward is a batch of warm sugar-coated rounds ready to fill with smooth lemon-vanilla pastry cream.

Ingredients

For the Gluten-Free Bomboloni Dough

• 1 cup (160 grams) certified gluten-free brown rice flour
• 1 cup (115 grams) certified gluten-free tapioca starch, plus more for dusting
• 1/2 cup (75 grams) certified gluten-free potato starch, not potato flour
• 1/3 cup granulated sugar
• 2 1/4 teaspoons instant yeast
• 2 teaspoons xanthan gum
• 2 teaspoons gluten-free baking powder
• 1 teaspoon fine sea salt
• 2 tablespoons whole psyllium husk
• 2/3 cup warm water, about 100°F to 110°F
• 2/3 cup lactose-free whole milk, about 100°F to 110°F
• 1 large egg, at room temperature
• 4 tablespoons dairy-free baking sticks, melted and slightly cooled, with no inulin or chicory root fiber
• 1 teaspoon apple cider vinegar
• 1 teaspoon pure vanilla extract

For the Lemon-Vanilla Pastry Cream

• 4 large egg yolks
• 1/3 cup granulated sugar
• 1/4 cup cornstarch
• 1/8 teaspoon fine sea salt
• 2 cups lactose-free whole milk
• 1 teaspoon pure vanilla extract or vanilla bean paste
• Finely grated zest of 1 lemon

For Frying and Finishing

• Neutral high-heat oil, such as sunflower, canola, or vegetable oil, enough to fill a heavy pot 2 1/2 to 3 inches deep
• 1/2 cup granulated sugar, for coating

Materials Needed

• Digital kitchen scale
• Measuring cups and spoons
• Stand mixer with paddle attachment or sturdy hand mixer
• Large mixing bowl
• Medium bowl
• Whisk
• Medium saucepan
• Rubber spatula
• Rolling pin
• 3-inch round cookie cutter
• Parchment paper
• Kitchen scissors
• Heavy-bottomed pot
• Deep-fry or instant-read thermometer
• Tongs or a slotted spoon
• Paper towels or a wire rack
• Piping bag with a medium round tip

How to Make It

1. Make the pastry cream first. Whisk the egg yolks, sugar, cornstarch, and salt in a medium bowl until smooth. Heat the lactose-free milk, vanilla, and lemon zest in a saucepan until steaming but not boiling.
2. Thicken and chill the filling. Slowly whisk about one-third of the hot milk into the yolk mixture, then pour everything back into the saucepan. Cook over medium-low heat while whisking until thick, continue for 1 minute after the first bubbles appear, then cover the surface and refrigerate.
3. Combine the dry ingredients. Add the brown rice flour, tapioca starch, potato starch, sugar, yeast, xanthan gum, baking powder, and salt to the mixer bowl. Whisk by hand until the mixture is even.
4. Prepare the psyllium gel. Stir the whole psyllium husk into the warm water and let it stand for about 1 minute. It should thicken into a loose gel before it goes into the dough.
5. Mix the wet ingredients. Whisk the warm lactose-free milk, egg, melted dairy-free baking sticks, apple cider vinegar, and vanilla together. Add the psyllium gel and whisk again until evenly combined.
6. Beat the dough. Pour the wet mixture into the dry ingredients and mix with the dough hook on medium speed for about 5 minutes, scraping the bowl as needed. The dough should be soft, thick, and slightly sticky.
7. Roll and cut the rounds. Dust the work surface lightly with tapioca starch and turn out the dough. Smooth it briefly with your hands, roll it to 1/2 inch thick, and cut ten 3-inch rounds, gathering the scraps only once if needed.
8. Proof until puffy. Place each round on its own square of parchment and arrange them on a tray. Cover loosely and let rise for 60 to 90 minutes, or until the rounds look visibly fuller and nearly doubled.
9. Heat the frying oil. During the final 30 minutes of proofing, pour oil into a heavy pot to a depth of 2 1/2 to 3 inches. Heat it to 325°F and keep a thermometer in place while you fry.
10. Fry in small batches. Lower two or three bomboloni into the oil with their parchment, wait about 15 seconds, then remove the paper carefully with tongs. Fry for about 2 to 2 1/2 minutes per side until golden and cooked through.
11. Coat, cool, and fill. Drain the bomboloni for about 2 minutes, then roll them in granulated sugar while warm. Once completely cool, make a small opening in the side of each doughnut and pipe in the chilled pastry cream.

Low-FODMAP Notes

Traditional bomboloni use wheat flour and regular dairy milk, while some packaged gluten-free blends add inulin, chicory root fiber, apple fiber, or other ingredients that may not suit a Low-FODMAP approach. This recipe uses separate rice flour and starches, lactose-free milk, and a dairy-free baking stick without added inulin or chicory so the ingredient list stays easier to evaluate.

This recipe is designed with Low-FODMAP-friendly ingredients but has not been laboratory tested. One bombolone is a practical starting portion, and remember that fried foods may affect personal comfort for reasons separate from FODMAP content.

Recipe Tips

• Weigh the flour and starches whenever possible because this dough depends on a precise flour-to-liquid balance.
• Keep the dough soft and sticky. Adding too much flour can make the finished bomboloni dense.
• Use the dough's visible rise as your guide because room temperature affects proofing time.
• Hold the oil close to 325°F so the centers have time to cook before the exterior becomes too dark.
• Fry only two or three at a time to prevent the oil temperature from dropping sharply.
• Wait until the bomboloni are completely cool before filling so the pastry cream stays thick.
• Serve the filled doughnuts the same day for the softest texture and freshest sugar coating.
