Growing up my mom made flan all the time. I remember it as a smooth, sweet, and creamy dessert topped with a caramelized topping. So whenever I see it on the dessert menu, I order it hoping it would be as creamy as my mom’s…but it never is. The ones I’ve tasted are a bit too dense for me.

So I asked her for her recipe and decided to make it myself. Boy, has it been a culinary adventure 🤣.
What is flan?
Flan is a custard dessert made of eggs, cream and sugar. There are many different versions of flan, or as I call it, “flavored” flan. There are peach flan, chocolate flan, pineapple flan, etc. However, my favorite is still the traditional flan, using just eggs, cream, and sugar.
Flan was introduced to Vietnam by the French and it has been a staple dessert since. The word “flan” is derived from the Old High German word “flado” meaning “flat cake”. Flan is said to have originated in ancient Rome as a savory dish due to a surplus of eggs. Eventually, they started to add honey to the dish and its popularity increased worldwide. As the recipe continued to travel, different cultures began to put their own twist on the recipe, making flan what it is today.

The caramel topping
This is going to sound crazy, but to me this was the hardest thing for me. I must have tried to make the caramel topping a dozen times before I finally figured it out. There are two ways to make the topping. One is the “wet” method and the other is the “dry” method. My mom’s original recipe calls for 2 tablespoons of water and 1/2 cup of sugar. However, when I did this, all I managed to do was to recrystallize the sugar, turning it into a big clumpy mess. I tried adjusting the amount of water but still ended up recrystallizing the sugar. I blame this on my crystallization techniques I learned back in the day 😂.
So I thought why not remove the water and just melt the sugar alone? Voila, it worked…beautiful brown caramel sauce. However, the sauce was still too thick to evenly spread across an 8 inch round baking pan. It wasn’t until I decided to add in 2 tablespoon of water after the sugar had melted that it gave me the consistency I wanted.
So what did I learn throughout this process?
- The “wet” method for making caramel sauce does not work for me. It may work for you, but I did not have much luck.
- Use a deep non-stick pot.
- When adding the water to the melted sugar, add it very slowly to prevent it from bubbling up too quickly. I also made sure I stirred the mixture while slowly adding the water.
- Make sure the sugar completely melts. This will give a nice, smooth, even layer of caramel on the top after baking.
Cleaning up the caramel pot
If you have caramel stuck to your pot, instead of trying to scrape the caramel off, add water to the pot and boil it. It will dissolve the caramel saving you scrubbing time, and your pot if you used a non-stick pot.
The custard
My mom’s recipe calls for a combination of sweet & condensed milk, water, and regular milk. However, I decided to use 2% milk instead to make it a bit healthier. The milk is heated to a boil then very slowly added to the sugar and egg mixture. When doing this, start off adding very slowly 1 ladle at a time. This is to prevent the eggs from scrambling. After the milk and egg mixture is combined, run it through a fine mesh strainer to catch any clumps before pouring it into the pan that has the caramel sauce.
Place the custard pan inside a bigger pan filled with hot water. I have a dedicated aluminum pan that I use for this. The first time I baked this, I forgot to add hot water and the custard came out very rubbery, almost a bread pudding texture, which is not good for flan. So make sure you add in hot water. The water level also matters. I always add enough hot water to make sure it covers at least 60% of the custard pan to ensure it comes out creamy and not rubbery. I used an 8 inch round cake pan.
Serving & storing flan
After the flan is cooked and cooled, run a butter knife around the edge of the cake pan to loosen it. Then place a plate over the top of the cake pan, invert quickly and it should come out easily. I serve flan in slices with some whipped cream on top…and fresh raspberries.
Left over flan can be stored in the fridge covered with saran plastic wrap. To me, it always tastes better the second or third day.

Bánh Flan (Vietnamese Flan)
Equipment
- 1 disposable aluminum pan or something that will hold the custard pan.
- 1 round (8 inch) baking pan for the custard.
Ingredients
- 6 eggs three whole eggs plus three egg yolks.
- 1 tbsp rum
- 1 cup sugar ½ is for the caramel sauce and ½ is for the custard filling.
- 2½ cup 2% milk
- 1 tsp vanilla extract
- 2 tbsp water to thin out the caramel sauce.
Instructions
Instructions for making the caramel sauce:
- Preheat the oven to 350oF
- Place ½ cup of sugar in a deep, non-stick pot and melt the sugar on medium heat. When the melted sugar gains a brownish color, very slowly add 2 tbsp water to thin out the sauce.

- Pour the caramel sauce into a round cake pan and move the cake pan around until the caramel sauce covers the bottom of the pan.

Instructions for making the custard filling:
- Place 3 whole eggs plus 3 egg yolks, vanilla extract, sugar, and rum into a bowl and beat until combined.
- In a pot, heat up the milk. When the milk is hot, slowly transfer into the egg, sugar, vanilla extract and rum mixture while whisking. If you have a stand mixture, leave the mixture running while adding the hot milk. Don't add the hot milk too quickly into the egg mixture, as it will scramble the eggs.
- After the milk and egg mixture is combined, strain it then pour on top of the caramel sauce.

- Place a big aluminum pan in a preheated oven first, and gently put the cake pan containing the custard inside the aluminum pan. Then fill the aluminum pan with hot water. Bake for 45 minutes or until an inserted toothpick comes out clean.

- After the flan is baked, remove it from the water bath to cool. Before serving, run a knife around the edge of the cake pan to loosen the flan.

- Place a plate on top of the flan and quickly turn it over. The flan should come out easily. Enjoy.
