Dim Sum Egg Tarts Recipe: Golden Crusts with Silky Yolk Hearts

This dim sum egg tart recipe delivers the perfect balance of crispy, golden crusts and silky, custardy yolk centers that make every bite unforgettable. 💛 The secret lies in a delicate pastry dough that encases a rich egg filling, baked just enough to set the edges while keeping the center gloriously runny. I've refined this recipe over years of trial and error—because getting that signature texture takes precision, but the results are worth every effort.

The foundation starts with a flaky, buttery puff pastry that creates the iconic dim sum shell, while the egg filling gets its signature texture from a precise mix of eggs, sugar, and cornstarch. Traditional methods call for hand-kneading the dough, but I've included a modern shortcut using store-bought puff pastry for those short on time. The key to success? Baking at the right temperature to achieve that golden-brown crust while keeping the yolk center warm and custardy.

What makes these egg tarts truly special is the contrast of textures—crispy yet tender crusts giving way to a creamy, molten yolk that practically pools on your spoon. Served warm or at room temperature, they're perfect for brunch, afternoon tea, or as a sweet treat with a cup of jasmine tea. The aroma alone will have everyone gathering around your kitchen, waiting for their turn.

Whether you're baking for a family gathering or treating yourself to a taste of Cantonese tradition, this recipe ensures restaurant-quality results every time. Troubleshooting tips included—like avoiding soggy crusts and ensuring the yolk stays perfectly set—make this recipe approachable for beginners while still impressing seasoned bakers. Let's get started on creating these golden, custardy delights.

The puff pastry is non-negotiable for that iconic crispy-yet-tender crust. Pepperidge Farm or Whole Foods brand are my go-tos—they thaw perfectly and handle shaping like a dream. If you're feeling ambitious, you can make your own dough (flour, butter, ice water, salt) for that extra flakiness, but store-bought saves time without sacrificing quality. Look for sheets that are evenly thick—about 1/8-inch—and avoid any that look cracked or dry. Pro tip: Let the pastry sit at room temp for 10 minutes after thawing to make rolling easier. The butter inside needs to stay cold for that signature flake, so don't let it warm up during prep.

No vanilla extract? Vanilla bean paste or even a pinch of vanilla sugar works in a pinch. The cornstarch is crucial for that silky yolk texture—don't skip it or you'll end up with a runnier filling. Short on eggs? Use 5 extra-large eggs instead of 6, but they won't fill the tarts quite as much. The sugar can be swapped for turbinado or coconut sugar if you're avoiding white sugar, though it might give a slightly different caramelization. And if you're making a big batch, double the egg wash—it's worth the extra golden sheen on those crusts. For the dough reinforcement, if you're making homemade dough, use bread flour instead of all-purpose for extra structure.

Thawed puff pastry keeps in the fridge for up to 3 days wrapped in parchment, but use it within 2 days for best texture. The egg filling can be prepped ahead and stored in the fridge for 24 hours—just whisk it again before filling the tarts. Baked tarts stay fresh for 2 days at room temp if stored in an airtight container, but they're best enjoyed warm. For reheating, pop them in a 350°F oven for 5-7 minutes—just until the crust is crispy again. Freeze unbaked tarts on a tray first, then transfer to a bag for up to 1 month. Bake straight from frozen, adding 2-3 minutes to the baking time.

Step-by-step instructions for dim sum egg tarts

Here's how to make restaurant-quality egg tarts with that signature golden crust and runny yolk center.

In a medium saucepan, combine the 6 whole large eggs, 0.5 cup granulated sugar, 2 tbsp cornstarch, 0.5 tsp salt, and 0.5 tsp vanilla extract. Whisk vigorously until no streaks remain and the mixture is smooth. This custard is the heart of your egg tarts—getting it right ensures that perfect silky texture.

Place the saucepan over medium-low heat and stir constantly with a silicone spatula. You want to heat the custard gently to 170°F—this is where the magic happens. The custard should thicken enough to coat the back of a spoon but still be pourable. If it starts to bubble or curdle, reduce the heat immediately. Remove from heat and let it cool slightly while you prepare the pastry.

Preheat your oven to 375°F. Lightly grease a 12-cup muffin tin (or use the included liners if your pastry sheets have them) and dust each cup generously with 0.25 cup cornmeal. This prevents sticking and helps create that classic dim sum tart shape.

Unfold the 2 sheets store-bought puff pastry and cut each sheet into 12 equal squares (about 3 inches per side). Press each square gently into the prepared muffin tin cups, pressing up the sides slightly to create a fluted edge. The pastry should come up about ½ inch on each side—this gives you that signature dim sum tart shape.

Carefully spoon the cooled custard into each pastry-lined muffin cup, filling them about ¾ full. The custard should be at room temperature—this helps it set evenly without creating a skin on top. Gently tap the muffin tin on the counter to level the custard and remove any air bubbles.

Bake for 25-30 minutes until the pastry is deep golden brown and the custard is just set but still slightly jiggly in the center. The top should look beautifully puffed with a crisp, golden crust. If the pastry browns too quickly, tent loosely with foil to prevent burning while the custard finishes baking.

While the tarts are still warm, prepare the egg wash by beating 1 whole egg with 1 tbsp water and 1 tbsp granulated sugar until smooth. Brush this generously over the tops of all the tarts. This final step creates that glossy, golden finish and adds a touch of sweetness that balances the rich custard.

Let the tarts cool in the pan for 5 minutes before transferring to a wire rack. Serve warm—the custard should be silky and slightly runny in the center, with a crisp, flaky pastry shell. These are best enjoyed fresh out of the oven, straight from the muffin tin!

Make-ahead tips for this recipe

Prep Ahead Dough

Make the pastry dough up to 2 days ahead and store it tightly wrapped in plastic between layers of parchment paper. I keep mine in the fridge—not the freezer—because cold dough is easier to roll out later. For extra flakiness, let the dough sit at room temperature for 30 minutes before shaping the tarts. This relaxes the gluten, making it more pliable. 💫

Custard Prep

Whisk the egg custard mixture the night before and refrigerate it in an airtight container. When ready to use, whisk again briefly to remove any surface film. I find this step saves 15 minutes of morning prep time. Just ensure the custard is at room temperature before filling the pastry—cold custard can cause the pastry to puff unevenly.

Unbaked Tarts

Assemble the tarts (pastry + custard) but don't bake them yet. Cover tightly with plastic wrap and refrigerate for up to 12 hours. This is perfect for overnight prep—just pop them in the oven first thing in the morning. Bake as directed, adding 2-3 extra minutes since they'll be colder. I love this method because it lets the flavors meld overnight.

Baked Storage

Store fully baked tarts at room temperature in an airtight container for 2 days. For longer storage, freeze them on a tray first (to prevent sticking), then transfer to a freezer bag for up to 1 month. Thaw overnight in the fridge before reheating. To revive the crust, warm in a 350°F oven for 5-7 minutes—just until golden again.

Egg Wash Secret

Prepare the egg wash (1 egg + 1 tbsp water + 1 tbsp sugar) the night before and store it in a small jar in the fridge. This saves time in the morning and ensures you won’t forget this crucial step. Brush it on just before baking—it adds that signature golden sheen and subtle sweetness that balances the rich custard. 🍯

Freezer-Friendly

For a true make-ahead win, bake the tarts, let them cool completely, then freeze them on a tray. Once frozen solid, transfer to a bag and store for up to 3 months. Reheat straight from frozen in a 375°F oven for 10-12 minutes—no thawing needed. The crust stays crispy, and the custard warms through beautifully. Perfect for lazy weekends!
