Pillowy soft doughnuts filled with silky vanilla bean custard and topped with a crackling caramelized sugar crust create an extraordinary dessert experience that combines two beloved classics. Each bite delivers the perfect textural contrast between the airy dough, velvety pastry cream, and that signature brittle sugar shell that shatters delightfully against your teeth. These gourmet treats transform ordinary doughnuts into something truly spectacular, worthy of special occasions yet approachable enough for ambitious home bakers to master with a bit of patience and attention to detail.
I first encountered these doughnuts at a small artisan bakery while traveling and became immediately obsessed with recreating them at home. After several test batches adjusting the custard thickness and sugar caramelization technique, this version finally captured that magical combination I remembered. My family now requests these for birthday celebrations, and friends have started expecting them at brunches. Even my father, who rarely eats sweets, can never resist these when they appear on the table.
Essential Components
- All purpose flour: Provides the necessary structure while maintaining tenderness in the dough
- Instant yeast: Ensures reliable rising without the guesswork of active dry varieties
- Whole milk: Contributes richness and tender texture to both dough and custard
- Egg yolks: Create silky smoothness in the pastry cream while adding richness
- Vanilla bean paste: Delivers intense flavor with beautiful specks throughout the filling
- Cornstarch: Stabilizes the custard to maintain the perfect pipeable consistency
- Unsalted butter: Enriches both components with incomparable flavor
- Granulated sugar: Creates the signature crackly top when properly caramelized
- Fresh lemon zest: Brightens the dough with subtle citrus notes
- Quality frying oil: Ensures proper cooking without imparting unwanted flavors
Baking Instructions
- Create Tender Dough:
- Combine warm milk with yeast and a teaspoon of sugar in a small bowl, allowing it to stand until foamy and active. Meanwhile, whisk together flour, remaining sugar, and salt in a large mixing bowl. Add the yeast mixture along with eggs, softened butter, and any flavor additions like vanilla or lemon zest. Knead thoroughly until the dough becomes smooth and slightly tacky.
- Develop Proper Structure:
- Transfer the dough to a lightly oiled bowl, cover, and let it rise in a warm place until doubled. For enhanced results, refrigerate overnight to develop more flavor. Once risen, gently deflate and turn onto a lightly floured surface.
- Shape Perfect Rounds:
- Roll the dough to one-inch thickness. Use a round cutter to portion doughnuts. Transfer cut doughnuts to parchment lined trays, cover loosely, and allow to proof until puffy.
- Fry To Golden Perfection:
- Heat oil in a heavy pot to 175°C. Fry doughnuts in small batches, turning once, until evenly golden brown. Remove and drain on a paper towel lined rack.
- Prepare Silky Custard:
- Warm milk in a saucepan. Whisk egg yolks with sugar until pale, then add cornstarch. Gradually stream in warm milk while whisking. Return to heat and cook until thickened. Stir in butter and vanilla until smooth.
- Fill With Precision:
- Cool custard completely. Transfer to a piping bag fitted with a small tip. Insert the tip into each doughnut, gently squeezing until properly filled.
- Create Signature Caramel:
- Sprinkle sugar evenly over the tops. Use a torch to melt and caramelize into a crisp, golden shell.

I learned through trial and error that allowing the caramel to set for exactly 90 seconds creates the perfect crack without becoming too hard. My daughter loves helping with the torching process, making this a special baking project we share. The first time I served these at a family gathering, my sister claimed they were better than her favorite bakery, which remains my proudest baking moment.
Flavor Inspirations
Transform these classic doughnuts with creative variations. Coffee infused custard creates a tiramisu inspired version. Chocolate lovers will appreciate a dark chocolate custard version. For fruit forward options, consider folding raspberry puree into the custard before filling.
Storage Solutions
Enjoy these doughnuts fresh. Store unfilled doughnuts at room temperature in an airtight container for up to one day. Refrigerate custard separately for up to three days. Assemble and caramelize just before serving for optimal texture.
Serving Suggestions
Serve on a wooden board with powdered sugar for contrast. Offer toppings like crushed pistachios or edible gold dust. Pair with espresso or cappuccino for a perfect balance of flavors.

Frequently Asked Questions
- → Can I make the dough without a stand mixer?
- Yes, you can mix by hand but it will require more time and effort to develop the gluten properly for a soft, elastic dough.
- → How long will these doughnuts stay fresh?
- They're best eaten the same day, especially to preserve the crisp caramel top. The filled doughnuts without caramel can last 1-2 days refrigerated.
- → Can I bake these instead of frying?
- While possible, baking will result in a different texture. If baking, use a 350°F oven for about l5 minutes until golden.
- → What's the best way to fill the doughnuts?
- Use a piping bag with a long filling tip. Insert it into the side and squeeze gently until you feel slight resistance.
- → How do I get the caramel layer perfect?
- Apply a thin, even layer of sugar and caramelize with a kitchen torch, moving constantly to prevent burning any one spot.
