These dainty pastry tubes blend flaky, buttery puff pastry with smooth vanilla custard. Every mouthful offers a wonderful contrast between the crunchy shell and luscious, creamy filling, making this a standout Italian sweet treat.
Whenever I whip up these cannoncini, my home gets filled with the wonderful smell of butter and vanilla. The way the pastry breaks against the velvety filling is so amazing that everyone wants to know how I made them.
Key Ingredients Breakdown
- Puff Pastry: Go for premium frozen dough with clear butter streaks. It should be fully defrosted but still cool to touch.
- Egg Yolks: Use fresh yolks at room temp for the creamiest filling. Darker yolks will give you better color.
- Milk: Whole milk makes the richest custard. Use fresh milk and warm it just until it steams.
- Vanilla Extract: Stick with real extract or actual vanilla beans for genuine taste. Skip the artificial stuff.
- Sugar: Regular granulated sugar works best in the custard. Add extra when rolling to get a caramelized outer crust.
Crafting Your Delightful Treat
- Making The Custard:
- Start by beating egg yolks, sugar, and vanilla until light and airy. You'll know it's ready when it falls in ribbons from your whisk.
- Adding Flour:
- Gently sift flour into your egg mix, making sure it's completely smooth. This step can't be rushed if you want silky custard.
- Heat Management:
- Warm milk until it steams but doesn't boil - about 180°F. Pour it slowly into the egg mix while constantly whisking to stop it from turning lumpy. Put it back on the heat and stir non-stop until thick.
- Working The Dough:
- Spread your thawed puff pastry on a sugar-coated surface to get even thickness. The sugar doesn't just add sweetness - it'll give you a tasty crunch after baking.
- Forming The Horns:
- Cut 1-inch strips and wrap them around metal tubes, making sure they overlap enough to stay closed. How you wrap them will decide their final look.
- Oven Time:
- Lightly coat with beaten egg, being careful not to let it drip and block the rising. Bake at 400°F until they're golden and super crisp.

My grandma from Italy always told me that great cannoncini need time - both when cooking the filling and putting everything together.
Careful Timing
Keep an eye on your pastries during the final baking minutes. They should turn a nice gold color but not get too dark.
Fancy Presentation
Only add filling right before you serve them to keep them nice and crispy. A light sprinkle of powdered sugar makes them look extra special.
Custom Touches
Try adding lemon zest or coffee to your custard. Each change gives you something new but still feels authentic.
Smart Storage
Keep empty shells in a sealed container. Only add filling when you're ready to eat them for the best texture.

After making these Italian treats for many years, I've found that getting both temperature and timing right is crucial. When done properly, these cannoncini taste just as good as ones from fancy Italian bakeries.
Frequently Asked Questions
- → Can I prepare these in advance?

- → Is store-bought custard okay?
- It works, but homemade custard gives a more authentic flavor that's worth the effort.
- → How should I store blanks?
