Ube Egg Tart Recipe: Filipino Pastry Magic With Silky Yolk Hearts

This ube egg tart recipe captures the essence of Filipino pastry magic—where delicate pastry meets velvety ube custard and golden yolk hearts. The secret lies in a crisp, flaky crust that encases a silky-smooth filling, balancing sweet purple ube with rich egg custard.

My version stays true to tradition while making it approachable for home bakers, with precise ratios that guarantee a perfect texture every time.

What sets these egg tarts apart is the ube halaya, a vibrant purple jam made from steamed and blended purple yam. This isn’t just any custard—it’s a harmonious blend of ube’s natural sweetness and egg yolks, creating a filling that’s both rich and tender.

The key technique? Baking the tarts in a water bath for a golden crust while keeping the custard perfectly set.

By the time you pull these from the oven, you’ll have golden, flaky shells filled with a glossy purple custard and a runny yolk heart that oozes with every bite.

The aroma alone—warm pastry with hints of vanilla and caramelized sugar—will have everyone asking for seconds. This recipe delivers restaurant-quality results with just a few simple techniques.

Whether you’re making them for a special occasion or a weekend treat, these egg tarts are worth the effort. The beauty of this recipe is its versatility—you can adjust the size (mini or full) or even experiment with vegan adaptations. Let’s get started on creating your own Filipino masterpiece.

Ingredients for ube egg tart

Golden crust meets purple ube custard with runny yolk hearts—just 14 ingredients for Filipino pastry perfection.

The ube is non-negotiable here. Fresh purple yam from an Asian market (not canned) gives the best flavor—look for vibrant purple flesh, not green or brown spots. Filipino grocery stores like 99 Ranch or H Mart carry it year-round. If you can't find fresh, ube halaya (purple yam jam) works in a pinch, but it won't be as rich. For the crust, European-style butter like Plugrá or Land O'Lakes makes all the difference—it's higher in fat, which equals flakier layers. Keep everything cold until you're ready to mix.

No ube? Sweet potato puree changes the color but keeps the sweetness. Short on condensed milk? Evaporated milk plus extra sugar works, though the texture will be slightly thinner. The egg yolks need to be room temperature—cold yolks create lumpy custard. For a vegan adaptation, swap butter for vegan butter or coconut oil and use flax eggs (1 tbsp ground flax + 3 tbsp water per egg). The baking powder is optional but gives a slight lift to the crust—skip it if you prefer a more traditional texture.

The ube halaya keeps for 5 days in the fridge, covered tightly. The pastry dough can be chilled for up to 2 days wrapped in plastic. Once assembled, these tarts are best eaten fresh but reheat beautifully—30 seconds in the microwave restores that warm, gooey perfection. For make-ahead prep, bake the tarts without filling, cool completely, then store filled tarts in the freezer for up to 1 month. Just thaw overnight before serving.

Step-by-step instructions for ube egg tart recipe

Here's how to create the perfect Filipino pastry with a buttery crust and vibrant purple ube filling.

First, steam the 1 lb purple yam (ube) until tender—about 20-25 minutes in a steamer. Once cool enough to handle, peel and mash it until smooth. In a saucepan, combine the mashed ube with 0.5 cup condensed milk, 1 tbsp cornstarch, and 0.125 tsp ground black pepper. Cook over medium heat, stirring constantly, until the mixture thickens to a pudding-like consistency—around 5-7 minutes. You'll know it's ready when it coats the back of a spoon smoothly. Let it cool completely before using.

This step is where the magic happens—the ube's natural sweetness blends perfectly with the condensed milk to create that signature vibrant purple filling. Don't rush the cooking; you want it thick enough to hold its shape when baked later. If it's too thin, cook it a little longer, but be careful not to burn it.

In a large bowl, combine the 2 cups all-purpose flour, 0.25 cup granulated sugar, 0.5 tsp salt, and 0.25 tsp baking powder. Cut in the 1 cup cold unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Add 1 whole large egg and 0.25 cup cold milk, mixing just until the dough comes together. Wrap it in plastic wrap and chill for at least 1 hour—this resting time is crucial for a flaky crust.

I like to handle the dough gently here—overworking it will make the crust tough. Once chilled, roll it out to fit your tart pans, pressing it evenly into the bottom and up the sides. The dough should be about 1/8-inch thick for that perfect crispy yet tender texture. Don't worry if it cracks a little; it's normal and won't affect the final result.

Preheat your oven to 350°F. Grease your tart molds with 1 tbsp vegetable oil, then line them with the rolled-out pastry dough. Fill each tart shell about 3/4 full with the cooled ube halaya. In a separate bowl, whisk the 4 whole egg yolks and 0.5 tsp vanilla extract until smooth, then pour this mixture evenly over the ube filling in each tart.

Bake for 25-30 minutes until the crust is golden brown and the filling is set but still slightly jiggly in the center. The top should have a beautiful golden hue, and you should see a slight puff in the crust. If the tops brown too quickly, tent them with foil to prevent over-browning while the centers finish cooking.

Let the tarts cool for 10 minutes before removing them from the molds. While still warm, sprinkle with a little extra granulated sugar for a touch of sweetness. Serve them at room temperature for the best texture—this allows the filling to set perfectly while keeping the crust crisp.

The finished tarts should have a delicate, flaky crust that gives way to the creamy ube filling with its signature purple hue. Each bite should offer a perfect balance of sweetness from the ube and richness from the egg yolks. These taste even better the next day when the flavors have fully melded together!

Essential equipment for great ube egg tart

Must-Have Tools

Start with a steamer basket—I use a stainless steel colander that fits snugly over a pot. This ensures even steaming for your ube without waterlogging. A pastry cutter or fork works best for cutting cold butter into flour, but you can also use your fingers if you're patient.

For shaping, a rolling pin with a 1/8-inch thickness guide helps maintain consistent dough thickness. 🌾

Tart Mold Essentials

Use mini muffin tins (24-count) for classic-sized tarts or 6-8 count tart pans for larger portions. I prefer silicone tart molds because they're flexible and easy to release, but metal muffin tins work too.

Grease them thoroughly with vegetable oil or butter to prevent sticking. For extra insurance, dust with flour after greasing. A small offset spatula helps spread the ube filling evenly.

Baking Gear

A baking sheet with a wire rack is perfect for cooling tarts after baking. This prevents soggy bottoms by allowing air circulation. For precise temperature control, invest in an oven thermometer—home ovens often run 25°F hotter or colder than set.

I recommend the Thermoworks Oven Thermometer for accuracy. A fine-mesh sieve helps dust extra sugar evenly over finished tarts. 🔥

Optional Upgrades

For professional results, a stand mixer with a dough hook attachment makes pastry dough effortless. A digital kitchen scale ensures precise measurements for the ube halaya—aim for 1:1 ratio of mashed ube to condensed milk.

For presentation, edible gold leaf or purple sprinkles add a festive touch. A pastry brush helps paint egg wash on crusts for extra shine.

Budget-Friendly Swaps

No steamer? Use a microwave-safe bowl with 1 inch of water and cover with plastic wrap—microwave on high for 8-10 minutes until ube is tender. Skip the pastry cutter? Pulse cold butter and flour in a food processor until crumbly.

For tart molds, greased ramekins work in a pinch. A spoon can replace a rolling pin if you press the dough with your hands instead. 💡
