Chinese Egg Custard Tarts Recipe: Silky Filling in Buttery Pastry

There’s a reason these tarts have captivated bakeries from Hong Kong to Boston. The contrast between buttery pastry and silky egg custard creates a texture experience that’s hard to forget.

I developed this version after testing multiple custard ratios to achieve that signature jiggle without cracking. The pastry requires patience—resting the dough ensures flaky layers that hold their shape.

Each bite delivers crisp edges, tender crust, and a filling so smooth it practically melts. The subtle sweetness lets the egg flavor shine, balanced by a whisper of vanilla.

Perfect for dim sum at home or an impressive dessert. This recipe delivers authentic results with precise techniques.

Ingredients for Chinese Egg Custard Tarts

Buttery pastry and silky custard require precise ingredients for authentic texture and flavor.

The butter is critical here—use European-style unsalted for superior flakiness. King Arthur Flour produces consistent all-purpose results. For pastry, keep ingredients ice-cold; the cold butter creates those coveted layers. Most supermarkets carry suitable products, but Whole Foods offers high-quality organic options. The flour should be fresh, as old flour loses its protein strength over time.

For the custard, room-temperature eggs ensure a smooth mixture. If whole milk isn’t available, half-and-half at reduced quantity works well. Vanilla extract can be substituted with one vanilla bean scraped for more intense flavor. Superfine sugar dissolves more completely, but regular granulated works with vigorous whisking. The salt quantity is small but essential for balancing sweetness.

Pastry dough can be rested overnight in the fridge (wrapped tightly) for up to 2 days. Custard filling should be used immediately after mixing. Completed tarts keep at room temperature for 1 day or refrigerated for 3 days—best served the day they’re baked.

Step-by-Step Instructions for Chinese Egg Custard Tarts

Master the technique for achieving delicate pastry and a velvety smooth custard filling.

Step 1: Prepare the Shortcrust Pastry Dough

In a food processor, pulse the 2 cups All-Purpose Flour with 0.25 cup Granulated Sugar and a pinch of the 0.25 tsp Salt to combine. Add the 1 cup Unsalted Butter, cut into small cubes, and pulse until the mixture resembles coarse crumbs with some pea-sized butter pieces visible.

Add the 2 whole Large Eggs (cold) and pulse until the dough begins to come together. Drizzle in 2 tbsp Ice Water, one tablespoon at a time, pulsing just until the dough forms a shaggy mass. Overworking develops gluten, which makes the pastry tough rather than tender.

Turn the dough out onto a lightly floured surface, press into a disk, wrap in plastic, and refrigerate for 30 minutes. This resting period allows the butter to firm up and the gluten to relax, ensuring a flaky texture.

Step 2: Shape the Pastry Shells

Remove the chilled dough from the refrigerator and let it soften slightly for 5-10 minutes—it should be pliable but not sticky. Divide the dough into 12 equal portions (about 1.5 oz each) and roll each into a ball.

Press each ball into a tart mold, starting at the bottom and working up the sides to create an even shell. Use your thumb to press the dough against the edges, ensuring it’s thin and uniform. Trim any excess dough from the top with a sharp knife.

Place the molds on a baking sheet and return them to the refrigerator to chill for another 15 minutes. This prevents the pastry from shrinking during blind baking.

Step 3: Blind Bake the Pastry Shells

Preheat the oven to 375°F. Line each chilled pastry shell with parchment paper and fill with pie weights or dried beans to prevent the dough from puffing up. Bake for 12-15 minutes until the edges are just beginning to turn light golden brown.

Carefully remove the weights and parchment, then return the shells to the oven for an additional 3-5 minutes until the bottoms are dry and lightly colored. Let the shells cool completely on a wire rack. They should be firm enough to hold the custard without sogging.

Step 4: Prepare the Custard Filling

Whisk together the 5 whole Large Eggs (room temperature) with the 0.75 cup Granulated Sugar until the mixture is smooth and slightly pale. Gradually whisk in the 0.5 cup Whole Milk (warm) and 1 tsp Vanilla Extract, ensuring no lumps remain.

Strain the custard mixture through a fine-mesh sieve into a pitcher or bowl with a spout. This step removes any air bubbles and ensures an ultra-smooth texture. The filling should be silky and free of any graininess.

Step 5: Fill and Bake the Tarts

Place the cooled pastry shells on a baking sheet and fill each one with the custard mixture, leaving about ⅛ inch of space at the top to prevent spillage. Gently tap the baking sheet on the counter to remove any air bubbles from the custard.

Bake at 350°F for 18-22 minutes until the custard is just set with a slight wobble in the center—it will continue to cook as it cools. Overbaking results in a dense, rubbery texture. Let the tarts cool in the molds for 10 minutes, then transfer to a wire rack to cool completely before serving.

Serving Suggestions for Leftovers

Tea Time Presentation

Serve these tarts slightly warm or at room temperature on a white porcelain platter for an elegant dim sum experience. The contrast of the golden pastry against the white surface highlights their beauty. I love using my Nonna’s vintage Florence pattern plates from Boston’s North End. 💛

Garnish Ideas

A light dusting of powdered sugar adds a delicate finish without overpowering the custard’s natural sweetness. For special occasions, top each tart with a single edible gold leaf—available at Whole Foods in the baking aisle.

Beverage Pairings

Traditionally, these pair perfectly with jasmine tea or pu-erh tea for afternoon dim sum. For Western palates, a light Earl Grey with a hint of bergamot complements the vanilla notes beautifully.

Afternoon Spread

Create a full dim sum experience with pork buns, shrimp dumplings, and turnip cakes. These tarts add the perfect sweet ending. Honestly, they disappear fastest at my family gatherings in the triple-decker.

Storage Display

If serving later, arrange cooled tarts in a single layer in an airtight container with parchment between layers. They’ll keep their beautiful shape for up to 3 days in the fridge. Bring to room temperature before serving. ✨

Portion Sizes

Each tart is perfectly sized as an individual serving. For larger gatherings, cut into wedges and arrange on a tiered stand. I learned this trick at a tiny dim sum spot in Chinatown—it makes any table look professional.
