Ingredients for taiwan egg tart

Eight ingredients transform into golden crusts hugging velvety custard—Taiwanese egg tart magic in your kitchen.

The butter is everything here—European-style unsalted like Plugrá or Land O'Lakes makes all the difference. Grab it cold from the fridge, cut into chunks, and handle it like you're making pie crust. King Arthur flour is my go-to for the dough—it's got that perfect protein balance for flakiness. If you can't find it, any all-purpose will work, but don't use bread flour. The sugar in the dough? Don't skip it—it helps tenderize the crust and creates that signature golden color. And for heaven's sake, use ice water. Room temperature water = tough dough.

Out of cornstarch? Arrowroot powder at the same amount works perfectly—it's just a bit pricier. No vanilla extract? Vanilla bean paste is even better, but plain sugar will get you by. The milk can be whole or 2%—full-fat gives the richest custard, but don't stress if that's not what you've got. For the dough, if your butter starts melting while mixing, pop it in the freezer for 10 minutes. And if your eggs are tiny? Use 5 large eggs instead of 4—just crack them into a bowl first to check size. The custard filling is forgiving, but the dough? Handle it gently or you'll end up with a tough crust.

Dough keeps for 3 days wrapped in plastic in the fridge—make it ahead, it's worth it. The custard? 2 days max in the fridge, but bake them fresh for best texture. These reheat beautifully—5 minutes at 350°F brings back that golden crust. Freeze unbaked tarts for 2 months—just bake straight from frozen, adding 5 minutes to time. And if you're feeling fancy, brush the baked tarts with a little egg wash for that restaurant shine.

Step-by-step instructions for Taiwan egg tarts

Here's how to create that legendary flaky crust and silky egg custard—every bite will transport you to Taipei.

In a large bowl, combine the 2.5 cups all-purpose flour and 0.5 tsp salt. Cut in the 1 cup cold, cubed unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces. This cold butter creates those signature flaky layers.

Add the 0.5 cup granulated sugar and the 1 whole cold large egg, mixing just until the dough comes together. Sprinkle in the 0.5 cup ice water and gently knead until smooth. Wrap the dough in plastic and refrigerate for at least 1 hour. The cold dough prevents spreading and ensures maximum flakiness when baked.

In a medium bowl, whisk together the 4 whole room-temperature large eggs, 0.75 cup granulated sugar, 1 cup whole milk, 1 tsp vanilla extract, and 2 tbsp cornstarch until completely smooth. This mixture should be uniform—no lumps—so strain it through a fine-mesh sieve if needed. The cornstarch is what gives those egg tarts their signature velvety texture.

Place the bowl over a pot of simmering water (double boiler method) and whisk constantly for 8-10 minutes until the custard thickens enough to coat the back of a spoon. Remove from heat and let cool completely before filling the shells. The custard should be thick but still pourable—like warm pudding.

Preheat your oven to 375°F. On a lightly floured surface, roll out the chilled dough to 1/8-inch thickness. Use a 3-inch round cutter to cut out circles, gently lifting and re-rolling the scraps for more dough. Place the circles on a parchment-lined baking sheet, spacing them 1 inch apart. The thin, even thickness is what creates that perfect crispy yet tender crust.

Press each dough circle gently into a 3-inch tart pan or use the cutter to press directly into the pan. The dough should come up the sides slightly—this creates that iconic high edge. Prick the bottom and sides with a fork to prevent puffing. Blind-bake for 12-15 minutes until just golden at the edges but still pale in the center. The dough should hold its shape but not be fully cooked through.

Carefully fill each partially baked shell with about 2 tablespoons of the cooled custard mixture. The custard should come up to about 1/2 inch from the top edge. Return to the oven and bake for an additional 12-15 minutes until the custard is set but still slightly jiggly in the center and the crust is deep golden brown. The center should have a slight wobble when gently shaken.

Let the tarts cool completely on a wire rack before serving. This resting time allows the custard to fully set while maintaining that perfect balance between firm exterior and molten center. The crust should be crisp enough to hold its shape when lifted, with a delicate crunch that gives way to the creamy egg filling.

For the best experience, serve the egg tarts warm straight from the oven. The contrast between the crispy, buttery crust and the silky custard is what makes these tarts legendary. If storing, keep them in an airtight container at room temperature for up to 2 days, or refrigerate for up to 1 week. Reheat in a 350°F oven for 5-7 minutes to restore that perfect texture.

Here's the thing—Taiwan egg tarts are all about that first bite. The moment the crust gives way to reveal that golden, custardy center is pure magic. Don't be tempted to overbake; you want that custard to be just set enough to hold its shape but still have that luxurious melt-in-your-mouth quality. Trust the 12-15 minutes baking time and the gentle wobble test—that's your golden ticket to perfection.
