Custard Tarts and Broken Hearts Recipe

Custard tarts and broken hearts—a sweet, comforting dessert that pairs a crisp, buttery pastry shell with a silky, vanilla-scented custard. This recipe is a classic in many British and Portuguese bakeries (think pastéis de nata), but this home-friendly version captures the same luscious texture and caramelized top without requiring a wood-fired oven. It works because the custard is gently baked until just set, creating a tender, creamy center that contrasts beautifully with the flaky crust.

Ingredients

1 sheet puff pastry (about 9.5 oz / 270 g), thawed if frozen
1 cup (200 g) granulated sugar
1/4 cup (30 g) all-purpose flour
2 cups (480 ml) whole milk
4 large egg yolks
1 large egg
1 teaspoon vanilla extract
1/4 teaspoon ground nutmeg (optional, for sprinkling)
Butter or nonstick spray, for greasing the muffin tin

Instructions

Preheat your oven to 400°F (200°C). Grease a 12-cup standard muffin tin with butter or nonstick spray.
On a lightly floured surface, roll the puff pastry sheet into a 12-inch (30 cm) square. Cut it into 12 equal squares (about 3×3 inches / 8×8 cm each). Press each square gently into a muffin cup, covering the bottom and sides. Trim any excess overhang. Prick the pastry bottoms with a fork to prevent bubbling. Chill the pastry-lined tin in the refrigerator while you make the custard.
In a medium saucepan, whisk together the sugar and flour. Gradually whisk in the milk until smooth. Place over medium heat and cook, stirring constantly, until the mixture thickens and just begins to bubble, about 5–7 minutes. Remove from heat.
In a separate bowl, whisk the egg yolks and whole egg together. Slowly pour about 1 cup of the hot milk mixture into the eggs, whisking constantly to temper them. Then pour the egg mixture back into the saucepan with the remaining milk mixture.
Return the saucepan to low heat and cook, stirring constantly, until the custard thickens to a pudding-like consistency, about 3–5 minutes. Do not let it boil. Remove from heat and stir in the vanilla extract.
Pour the custard through a fine-mesh strainer into a large measuring cup or bowl to remove any lumps. Let it cool for 5 minutes, stirring occasionally.
Remove the pastry-lined muffin tin from the refrigerator. Pour the custard evenly into each pastry cup, filling almost to the top (about 3 tablespoons per cup). Sprinkle the tops with nutmeg if using.
Bake for 15–18 minutes, until the pastry is golden brown and the custard is set around the edges but still slightly jiggly in the center. If you want a darker, caramelized top, switch to broil for the last 1–2 minutes, watching closely.
Let the tarts cool in the pan for 10 minutes, then carefully remove them with a small spatula or knife. Serve warm or at room temperature.

Tips

Substitutions: For a gluten-free version, use a gluten-free puff pastry or a shortcrust pastry made with gluten-free flour. For a dairy-free version, substitute whole milk with oat milk or almond milk, and use dairy-free butter or oil for greasing—note that the custard may be slightly less rich.
Storage: Custard tarts are best eaten the day they are made, but they can be stored in the refrigerator for up to 2 days. Cover loosely with plastic wrap to prevent a skin from forming.
Common mistakes: Overbaking is the most common issue—the custard will curdle and become rubbery. Remove them from the oven when the center still has a slight wobble. Also, make sure to temper the eggs properly; adding hot milk too quickly will scramble them.
Pastry handling: Keep the puff pastry cold until you are ready to use it. If it becomes too warm, it will shrink during baking. If the pastry puffs up too much during baking, you can press it down gently with the back of a spoon after removing from the oven.

Serving Suggestions

These custard tarts are delightful on their own, but you can elevate them with a dusting of powdered sugar or a drizzle of honey. They pair beautifully with a strong cup of espresso or a pot of Earl Grey tea. For a dessert platter, serve them alongside fresh berries or a dollop of lightly sweetened whipped cream. The contrast of the crisp pastry and creamy custard makes them a satisfying ending to any meal.

Variations

Portuguese-style (Pastéis de Nata): Increase the sugar to 1 1/4 cups (250 g) and add a cinnamon stick to the milk while heating (remove before baking). Brush the pastry with a beaten egg before filling for extra shine. The custard will be sweeter and more caramelized.
Lemon zest: Add the zest of one lemon to the milk while heating for a bright, citrusy note. Remove the zest before mixing with the eggs.
Chocolate custard: Melt 1/2 cup (85 g) of dark chocolate and whisk it into the custard after straining. This creates a rich, chocolatey version.
Spiced variation: Add 1/2 teaspoon of ground cinnamon and a pinch of cardamom to the custard for a warming flavor profile.

Storage and Reheating

Store leftover custard tarts in an airtight container in the refrigerator for up to 2 days. To reheat, place them on a baking sheet and warm in a 350°F (175°C) oven for 5–7 minutes, until the pastry is crisp again and the custard is warmed through. Avoid microwaving, as it will make the pastry soggy and the custard rubbery. If you prefer cold tarts, they can be enjoyed straight from the fridge—just let them sit at room temperature for 10 minutes to soften slightly.

Frequently Asked Questions

Can I use pre-made shortcrust pastry instead of puff pastry? Yes, absolutely. Shortcrust will give a sturdier, more cookie-like base. Roll it out to about 1/8-inch (3 mm) thickness, line the muffin cups, and blind-bake at 375°F (190°C) for 10 minutes before adding the custard to prevent a soggy bottom.

Why did my custard curdle? Curdling happens when the custard is overheated or the eggs are added too quickly without proper tempering. Always whisk the eggs constantly while adding the hot milk slowly, and cook the final custard over low heat, stirring constantly. If you see any lumps, you can strain them out, but the texture will be slightly less smooth.

Can I make these ahead of time? You can prepare the custard and pastry up to a day in advance. Store the custard in the refrigerator and the pastry-lined tin in the fridge. Assemble and bake when ready to serve. Baked tarts are best within a few hours, but they will keep for 2 days refrigerated.

How do I get a caramelized top without a torch? The broiler method works well: after baking, switch to broil for 1–2 minutes, watching closely so the sugar doesn’t burn. Alternatively, sprinkle a little extra sugar on top before broiling to help achieve a crackly crust.

Can I use low-fat or skim milk? You can, but the custard will be less rich and may not set as firmly. Whole milk or a combination of milk and heavy cream (1/2 cup cream + 1 1/2 cups milk) will yield the best texture and flavor.

Is it safe to eat the custard if it’s slightly jiggly? Yes, as long as the eggs are fully cooked. The custard is safe when it reaches an internal temperature of 160°F (71°C) (the USDA FSIS safe minimum for egg dishes). The jiggle in the center is normal and will set as it cools. Use a food thermometer to check if you’re unsure.
