Hokkaido egg tarts are a beloved Hong Kong bakery favorite, known for their impossibly creamy, pudding-like custard nestled in a crisp, buttery shortcrust pastry. Unlike the classic Portuguese egg tart with its caramelized top, the Hokkaido version features a smooth, jiggly custard that’s rich with milk and eggs, offering a delicate sweetness that’s utterly satisfying. This recipe delivers that same luxurious texture at home, using a simple yet effective method for a bakery-quality result.
Ingredients
- For the pastry:
- 1 1/4 cups (160 g) all-purpose flour
- 1/4 cup (30 g) confectioners’ sugar
- 1/2 cup (115 g) cold unsalted butter, cut into small cubes
- 1 large egg yolk
- 1-2 tablespoons ice water, as needed
- For the custard filling:
- 1 cup (240 ml) whole milk
- 1/2 cup (120 ml) heavy cream
- 1/3 cup (65 g) granulated sugar
- 3 large egg yolks
- 1 large whole egg
- 1 teaspoon vanilla extract
Instructions
- Make the pastry: In a food processor, pulse together the flour and confectioners’ sugar. Add the cold butter cubes and pulse until the mixture resembles coarse crumbs. Add the egg yolk and pulse a few times. With the processor running, add ice water 1 tablespoon at a time until the dough just begins to clump together. Turn the dough out onto a lightly floured surface, shape into a disc, wrap in plastic wrap, and refrigerate for at least 30 minutes.
- Preheat and prepare tins: Preheat your oven to 375°F (190°C). Lightly grease a 12-cup muffin tin or use 12 individual tartlet molds.
- Line the tins: On a lightly floured surface, roll the chilled dough to about 1/8-inch thickness. Using a round cutter slightly larger than your muffin cups, cut out circles. Press each circle gently into the muffin cups, ensuring the dough comes up the sides evenly. Prick the bottoms with a fork to prevent air bubbles. Chill the lined tins for 15 minutes while you make the filling.
- Make the custard: In a medium saucepan, combine the milk, heavy cream, and granulated sugar. Heat over medium heat, stirring occasionally, until the sugar dissolves and the mixture is steaming but not boiling. Remove from heat.
- Temper the eggs: In a separate bowl, whisk together the egg yolks, whole egg, and vanilla extract. Slowly pour about 1/2 cup of the warm milk mixture into the egg mixture, whisking constantly. Then, pour the tempered egg mixture back into the saucepan with the remaining milk, whisking to combine. Strain the custard through a fine-mesh sieve into a liquid measuring cup for a silky texture.
- Blind bake the shells: Line the chilled tart shells with parchment paper or foil and fill with pie weights or dried beans. Bake for 12 minutes. Remove the parchment and weights, and bake for another 3-5 minutes, or until the pastry looks dry and lightly golden. Remove from the oven and reduce the oven temperature to 325°F (160°C).
- Fill and bake: Carefully pour the custard into the pre-baked tart shells, filling each about 3/4 full. Bake at 325°F (160°C) for 15-20 minutes, or until the custard is just set around the edges but still slightly jiggly in the center. The internal temperature of the custard should reach 160°F (71°C) as a safe minimum for egg dishes, per USDA FSIS guidelines.
- Cool and serve: Let the tarts cool in the pan for 10 minutes, then carefully transfer to a wire rack to cool completely. Serve warm or at room temperature.
Tips
- Cold butter is key: For a flaky, tender pastry, the butter must be very cold. If it warms up, the dough will become tough. Pop the cubed butter in the freezer for 10 minutes before using.
- Don’t overwork the dough: Pulse the food processor just until the dough starts to come together. Overworking develops gluten, which makes the crust tough.
- Strain the custard: Straining removes any cooked egg bits and ensures a perfectly smooth, silky texture.
- Avoid overbaking: The custard will continue to set as it cools. Pull them out when the center has a slight wobble—they’ll finish cooking from residual heat.
Serving Suggestions
These tarts are delightful on their own as an afternoon treat with tea or coffee. For a more decadent dessert, serve them slightly warm with a dollop of lightly sweetened whipped cream or a scoop of vanilla ice cream. A dusting of ground cinnamon or nutmeg on top adds a lovely aromatic touch.
Variations
- Matcha Hokkaido Tarts: Whisk 1 tablespoon of matcha powder into the milk mixture before heating for a vibrant green tea flavor.
- Chocolate Hokkaido Tarts: Add 2 ounces (55 g) of finely chopped dark chocolate to the warm milk mixture, stirring until melted, before tempering the eggs.
- Puff Pastry Version: For a quicker alternative, use store-bought puff pastry sheets instead of the homemade shortcrust. Cut and fit them into the tins, then blind bake as directed.
Storage and Reheating
Store leftover Hokkaido egg tarts in an airtight container in the refrigerator for up to 3 days. To reheat, place them in a preheated 300°F (150°C) oven for 5-7 minutes, or until warmed through. Avoid microwaving, as it can make the pastry soggy and the custard rubbery. For best texture, enjoy them within 24 hours.
Frequently Asked Questions
Why did my custard curdle? Curdling happens when the eggs are heated too quickly or at too high a temperature. Always temper the eggs by slowly adding warm milk while whisking, and bake at a low temperature (325°F / 160°C). Also, be sure to strain the custard before baking.
Can I make the dough ahead of time? Yes! The pastry dough can be made up to 2 days in advance and kept refrigerated, or frozen for up to 1 month. Thaw overnight in the refrigerator before rolling out.
Can I use only egg yolks for the filling? Using all yolks will make an even richer, more custard-like filling. You can replace the whole egg with two additional yolks, but the texture will be denser and more like a crème brûlée.
My tart shells shrank during baking. What went wrong? Shrinkage is usually caused by overworking the dough or not chilling it enough before baking. Make sure to chill the lined tins for at least 15 minutes before blind baking, and don’t stretch the dough when pressing it into the molds.
Can I make these without a muffin tin? Absolutely. Use individual tartlet molds with removable bottoms, or even small ramekins. Just adjust the baking time slightly, as smaller tarts will bake faster.
Why are my tarts soggy on the bottom? A soggy bottom is often due to under-baking the pastry shell. Ensure the blind-baked shells are fully dry and lightly golden before adding the custard. Also, avoid overfilling the shells with custard.
