Flan used to be a dessert I love to order but rarely make at home because most recipes produce a full tray. That's why I came up with a single-serve approach. Cooking it in a ramekin keeps the custard smooth and creamy while the caramel layer melts beautifully over the top. My chocolate crème brûlée delivers the same rich custard experience in a manageable portion.
The smaller size also cooks faster than traditional leche flan, and I found the ramekin helps the custard set more evenly. It's a simple way to enjoy a classic Filipino dessert without leftovers sitting in the fridge for days. When I'm planning a small dessert spread, I like to pair it with crispy banana turon lumpia, another Filipino-inspired treat.
Ingredients
You will need a few key ingredients to make a delicious Filipino leche flan. These include eggs, condensed milk, evaporated milk, and sugar.
Eggs give the dessert its creamy texture, while the combination of condensed milk and evaporated milk adds sweetness and richness. Sugar is used to make the caramel sugar sauce that coats the custard.
Here's what you'll need to make the recipe:
- egg yolks
- evaporated milk
- sweetened condensed milk
- key lime juice
- vanilla extract
- light brown sugar
- water

Instructions
Preheat your toaster oven or air fryer on "bake" setting to 350°F (175°C). You can also use a regular oven to make leche flan if that's all you have.
Heat light brown sugar and water in a small saucepan over medium heat. Bring to a gentle simmer and swirl the pan occasionally. Once the sugar has caramelized and reached your desired color, immediately turn off heat.
Pour caramelized sugar into a ramekin or small oval baking pan. Allow to cool and set.
In a bowl, break egg yolks and stir in one direction using a spatula.
Gradually add condensed milk, evaporated milk, key lime juice, and vanilla. Continue stirring until all the ingredients are well-blended. Do not over stir.
Place a fine mesh strainer over a glass measuring cup and pour the egg mixture.
Pour egg mixture over the prepared ramekin baking dish. Place a pan on the oven tray. Gently transfer ramekin in the pan. Carefully pour hot water into the pan (bain marie, also known as water bath), not the ramekin. Cover with foil.
Slowly insert the tray into the middle of the oven. Bake for 35 minutes or until the middle part comes out clean when a toothpick or knife is inserted. Allow the custard and ramekin to completely cool before you invert in on to a plate. Refrigerate to chill.
Hint: When melting sugar to create the caramel layer, use low to medium heat. Avoid stirring the sugar too frequently; instead, let it melt and caramelize gradually. Stir only as needed to distribute heat evenly and prevent burning. Watch the color carefully, aiming for a rich molasses brown without letting it become too dark or bitter.
Tips
- After pouring the custard into the ramekin, gently tap it on the counter a few times. This brings trapped air bubbles to the surface so they don't create tiny holes in the custard as it cooks. Smooth custard starts with eliminating those bubbles early.
- After pouring the caramel in the ramekin, allow it to fully set and harden before pouring in the custard mixture. If the caramel is still very hot or liquid, it can partially mix into the custard and dull the clean caramel layer.
- Because ramekins have straight sides, the custard can cling slightly after chilling. Running a thin knife gently around the edge before inverting helps the flan release cleanly so the caramel flows evenly over the top.
- Leche flan technically sets once cooled, but the texture improves after at least 4 hours in the refrigerator. The custard firms slightly and the caramel softens into a smooth sauce that coats the dessert when unmolded.
Variations
You can make a creamy leche flan in various flavors and shapes. Here are some simple variations of the recipe:
- Ube leche flan: Add about 1 to 2 teaspoons of ube extract or a small spoonful of ube halaya to the custard mixture. This gives the flan its signature purple color and a mild nutty sweetness. Because ube adds a bit more density to the custard, the flan may take an extra minute or two to fully set.
- Coffee leche flan: Dissolve a small amount of instant coffee in warm milk or cream before mixing it into the custard. The coffee balances the caramel sweetness and adds a deeper roasted flavor. This variation does not noticeably change the cooking time but slightly darkens the custard.
- Cheese-topped leche flan: Sprinkle a small amount of finely grated mild cheese over the flan after unmolding. The salty cheese contrasts with the caramel and custard, which is a popular combination in many Filipino desserts. It does not affect the bake, but it adds a richer, slightly savory finish.
Storage
Leftover flan can be stored in an airtight container in the refrigerator for up to three days. It is important to keep it covered to prevent any odors from seeping into the delicate custard. When storing leche flan, it is best to place it in a single layer to maintain its shape and prevent any damage.
Consuming leche flan within a few days is recommended for optimal taste and texture. Over time, the creme caramel may become less creamy and develop a slightly grainy texture. To ensure you enjoy the best flavor, it's best not to keep leftover leche flan for too long.

Hi Lisa, as a single retired gal, I love your blog & recipes for small portions. Can this flan be cooked in a regular oven? I have a Ninja airfryer/broiler/baker, etc, etc. It folds up off the counter when not in use, very narrow, a ramekin might hit the top. Thanks in advance for a reply.
Lisa MarcAurele says
Dona, you can use a regular sized oven if needed. I would just keep an eye on it towards the end (after 25-30 minutes) and bake until the center comes out clean when a toothpick is inserted. Temperature will be the same.

Looks like a traditional recipe, using yolk only... but I hope you create categories for "the other half of the egg" one of these days. Since we're using only partial cans of sweetened + evaporated milk, and they are items I rarely use... how would I use the remainder of those ingredients?
Lisa MarcAurele says
Thanks for the feedback. You can use the site search for ingredients like "egg white" or "evaporated milk" but I'll look into linking those ideas within the post and in categories.

Leche Flan is one of my favorite desserts but I've never tried making it on my own again after one failed attempt haha! But I found your recipe just as I was craving for it and decided to try again. I loved the texture of the Leche Flan and the sweetness was just perfect to my taste!
JM says
I used pandan extract in my flan and added some sliced mangoes. It has a delightful combination and aroma. Definitely making it again!
Marina says
Hello! Can I use muffin pans if i don't have any ramekins? how will the temp or time change? thanks!
Lisa MarcAurele says
Muffin tins should work. The cooking time depends on the size but I'd say leave the temp the same and cook a little longer keeping an eye on them at the end.
