How to Make Ube Leche Flan
Start by making the caramel sauce. You can add one or two teaspoons of water to the sugar as it melts and caramelizes. This will help prevent it from scorching, which you want to avoid. Scorched caramel give the flan a bitter taste.
Make the Caramel
- Add the sugar to a sauce pan. Start with a medium heat and let the sugar melt. Stir it frequently so it does not scorch.
- Once the sugar has melted and turned brown, spoon 2 to 2 ½ tablespoons into each ramkin. Set aside to harden and cool.
Prepare the Egg Yolks
You will add the ube during this step also. The ube extract is the easiest to work with, just add 1 to 1 ½ teaspoon of the extract to the mixture.
If using the powdered ube sweet potato, reconstitute ¼ cup in a small bowl with ⅓ water. Mix until you get a thick slurry. Using a coffee filter, add the ube mixture into the cone of the filter and squeeze out about 1 tablespoon of liquid. Add to the leche flan mixture.
- Crack twelve eggs, leaving the whites in a separate container. Save them for another recipe.
- Whisk the egg yolks with the condensed milk, vanilla, milk, and ube extract.
Mix and Prepare Ramekins
- Whisk the ingredients until fully blended.
- Divide the flan mixture equally among the six ramekin.
Cover and Bake
We are not steaming this Ube leche flan as traditionally done. We are going to cover and use a bain marie, or a hot water bath used with typical creme brulee's or custards.
You an use a set specifically made for this, it comes with the ramekin that fit perfectly into an easy to lift in and out rack. Or you can use a 9 x 13 baking pan and add the water after setting it in the oven.
- Use small pieces of aluminum foil to cover each ramekin. Place in the bain marie rack and pan, or set into a 9 x 13 baking pan.
- Fill the baking pan with hot water to 1" from the top of the ramekins. Bake in the oven at 325 F for 50 minutes. Remove and refrigerate 2-3 hours.
Serving Suggestions
After the leche flan has set up in the refrigerator remove the aluminum foil covers. Using a thin knife, run the knife around the inside of the ramekin to release the flan from the sides.
Run hot water over the base of the ramekin, then place a saucer over the top. Tip upside down so the flan falls out onto the saucer. The caramel sauce will drizzle down the sides.
Serve this beautiful dessert with Adobong Chicken Liver on top or with White Rice. It can be accompanied by our Traditional Pork Lumpia or Fresh Vegetable Lumpia, followed with our Filipino Banana Turons for dessert!

Substitutions and Variations
The only difference between regular leche flan and ube leche flan is the ube. You can simply leave it out and make a splendid, rich leche flan!
Equipment
Equipment can have a big impact on how a recipe turns out. Stone bakeware takes longer to heat up than metal pans, and also retain heat for longer, which could make the recipe more watery, or burnt on the outsides. The baking tools and supplies I used for this recipe are as follows:
- Creme Brulee Bake Set (water bath pan, rack, and 6 ramkins)
- Liquid Ube Extract (super easy to work with!) OR
- Powdered Ube (you can make your own Ube liquid with this powdered yam)
Storage
Cover any leftover ramkins of ube leche flan. Wait to turn them out until ready to serve. Just cover with plastic wrap and store in the refrigerator for up to 5 days. Run a little hot water on the bottom of the ramkin before serving. This will allow the cold caramel sauce to release the set up dessert.
Tips for Success
- When working with ube extract or the powdered ube, wear some disposable nitrile gloves, as it does take some washing to remove the purple.
