Taiwan Egg Tart Recipe: Crispy Lattice Crust With Silky Egg Cream

This Taiwanese egg tart recipe delivers the perfect balance of a crispy lattice crust and silky egg custard that's become a global obsession. 💛 The secret lies in the delicate pastry technique and precise baking—no shortcuts can replicate that iconic texture.

I've perfected this version after countless trials, ensuring the crust stays golden and flaky while the custard remains rich and smooth.

The recipe begins with a simple buttery pastry dough that's rolled thin and cut into diamond shapes to create the signature lattice pattern. This isn't just about aesthetics—each cut allows heat to circulate perfectly, ensuring even baking.

The egg custard filling requires patience: eggs, sugar, and milk must be tempered carefully to avoid curdling, resulting in that signature velvety texture.

By the time these tarts emerge from the oven, you'll have golden-brown crusts with intricate lattice designs and custards so smooth they practically melt in your mouth. The contrast between the crisp exterior and creamy interior is what makes these tarts irresistible.

Each bite offers a perfect harmony of textures and flavors that's hard to resist.

While the classic version uses white sugar, you can easily customize with black sugar or matcha for unique variations. These tarts are perfect for breakfast, afternoon tea, or even dessert. Let's get started on creating your own batch of these beloved Taiwanese treats.

Ingredients for taiwan egg tart

Buttery pastry meets velvety custard in this iconic Taiwanese recipe—just 13 ingredients for golden lattice perfection.

The butter is non-negotiable here—European-style butter with high fat content (82%+) gives that signature flakiness. Plugrá or Land O'Lakes European Style are my go-tos, but any good-quality butter will work. Keep it cold when cutting into the flour—this is where the lattice magic begins. The flour should be soft wheat (all-purpose), not bread flour, for that tender yet crisp texture. If you're in a rush, King Arthur or Bob's Red Mill are reliable brands that stay fresh longer. Pro tip: Chill your rolling pin too—it helps prevent the dough from sticking.

No vanilla extract? Vanilla bean paste works perfectly, or even a pinch of vanilla sugar if that's what you've got. The custard requires tempering the eggs—whisk yolks and sugar first, then slowly add warm milk to avoid curdling. For the lattice cuts, use a sharp pizza cutter or small knife—clean cuts are key for that professional look. Want to experiment? Swap white sugar for black sugar (it caramelizes beautifully) or add a teaspoon of matcha powder for a green tea twist. The cornstarch is crucial—it prevents the custard from becoming gummy, so don't skip it.

The dough can be chilled for up to 48 hours—this actually improves flavor. Wrap it tightly in plastic wrap and store in the fridge. The custard filling should be made fresh (it doesn't store well), but you can prep the dough and crust shapes ahead. These tarts are best served warm—reheat at 350°F for 8-10 minutes to restore that perfect contrast of crispy crust and silky filling. For make-ahead baking, assemble the tarts on a parchment-lined tray, cover loosely, and bake straight from the fridge—just add 2-3 extra minutes to the baking time.

Step-by-step instructions for taiwan egg tarts

Here's how to nail that signature crispy lattice crust and velvety egg custard every time.

In a large bowl, combine the 3.5 cups all-purpose flour, 0.25 cup granulated white sugar, 0.5 tsp diamond crystal kosher salt, and 0.5 tsp baking powder. Mix until evenly distributed. Cut in the 1 cup cold unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces.

Add the 4 whole large eggs and work quickly to combine into a shaggy dough. The cold butter is crucial—it prevents gluten development and ensures flaky layers. Gradually add the 0.25 cup ice water, 1 tbsp at a time, mixing gently until the dough just comes together. Don't overwork it or the crust will toughen.

Divide the dough into 12 equal portions (about 3.5 oz each) and flatten into discs. Wrap each in plastic wrap and chill for 30 minutes. This resting period relaxes the gluten and makes rolling easier. While chilling, preheat your oven to 350°F and grease a 12-cup tart pan with butter.

Roll each dough disc into a 12-inch circle (about ⅛-inch thick) on a floured surface. The dough should be cold enough to hold its shape but pliable enough to roll. Here's the pro tip: I like to use a pizza cutter to make the lattice cuts—it gives clean, even lines every time.

Carefully transfer each rolled crust to the tart pan, pressing gently into the corners. Cut the crust into 12 equal strips radiating from the center, leaving a 2-inch wide border uncut. Weave the strips in a lattice pattern, pressing edges to seal. Bake for 20-25 minutes until the edges are golden brown and the crust feels firm to the touch.

Remove from oven and immediately press down the centers with a round cutter or glass to create the classic egg tart bowl shape. Return to oven for 2-3 minutes to set. The crust should be crisp but not burnt—watch closely as ovens vary. Let cool for 5 minutes before filling.

In a medium saucepan, whisk together the 4 whole egg yolks, 0.5 cup granulated sugar, and 1 tbsp cornstarch. Slowly pour in the 1.5 cups whole milk while whisking constantly. Return to medium heat and cook, stirring vigorously, until the mixture thickens enough to coat the back of a spoon (160-165°F internal temperature).

Remove from heat and stir in the 0.5 tsp vanilla extract and 2 tbsp unsalted butter. The custard should be smooth and glossy—if it's too thick, whisk in 1-2 tsp hot milk to loosen. Here's where patience pays off: let the custard cool to room temperature before filling the tarts to prevent cracking.

Pour the cooled custard into the warm tart shells, filling each ¾ full. The custard should sit just below the rim—overfilling causes spillage during baking. Bake at 325°F for 25-30 minutes until the custard is set but still slightly jiggly in the center. A toothpick inserted should come out clean.

Let cool completely before removing from the pan. The contrast between the crisp lattice crust and silky custard is what makes these tarts legendary. Serve warm or at room temperature—each bite should deliver that perfect balance of textures and flavors.

Troubleshooting your taiwan egg tart

Crust Too Pale

If your lattice crust emerges pale instead of golden, you likely need to increase the baking time or temperature. I find that 375°F works better for deeper color—just reduce baking time by 2-3 minutes to avoid burning.

Brush the crust with egg wash (1 egg + 1 tbsp water) before baking for extra shine. For even browning, rotate pans halfway through baking. 🌟

Custard Curdling

Curdled custard usually means the eggs were added too quickly to hot milk. Always temper the eggs by whisking yolks and sugar first, then slowly adding warm milk (never boiling).

If it starts curdling during cooking, immediately remove from heat and whisk vigorously. For extra insurance, strain the custard through a fine-mesh sieve before filling. 💡

Lattice Not Holding

Floppy lattice strips often mean the dough wasn't chilled enough or the cuts weren't clean. Press the strips firmly into the base before weaving, and chill the assembled crusts for 15 minutes before baking.

Use a sharp pizza cutter for precise cuts—dull blades crush the dough. If strips still sag, bake at 325°F instead of 350°F for better structural support. ✨

Filling Spills Over

Overfilled tarts create messy overflow during baking. Fill shells only ¾ full—the custard will expand slightly. For extra insurance, chill the filled tarts for 10 minutes before baking to thicken the custard.

If using a muffin tin instead of a tart pan, reduce baking time by 3-5 minutes to prevent spillage. 🔥

Dough Too Sticky

Sticky dough usually means too much water was added. Start with ¼ cup ice water and add 1 tbsp at a time until the dough just holds together. If it's still sticky, sprinkle 1-2 tbsp more flour and knead gently.

Avoid overworking—just 8-10 turns with a dough scraper is enough. For extra insurance, wrap the dough tightly in plastic and chill for 30 minutes before rolling. 💫

Custard Too Thin

Runny custard often means it wasn't cooked long enough or the cornstarch wasn't fully activated. Cook until the mixture reaches 165°F and coats the back of a spoon. For extra thickness, mix 1 tbsp cornstarch with 2 tbsp cold water, then stir into the hot custard.

If it's still too thin, simmer for 1-2 more minutes until it thickens properly. 💪
