Vietnamese Flan Cake

Creme caramel meets the fluffiest sponge ever in what might just be one of my favourite ever desserts. This Vietnamese flan cake is sweet and creamy, light and airy, plus that just-set toffee is taken juuuuust to the edge for a rich finish. The perfect finish to your next dinner party, at-home date night or special occasion.

10 minutes
30 minutes +6 hours to set
Makes 4

½ cup caster sugar


Creme caramel

375ml (13 fl oz) whole milk

375ml (13 fl oz) sweetened condensed milk

6 eggs

1 tbsp vanilla bean paste



50g (1.7 oz) caster (superfine) sugar

3 egg yolks

30g (1 oz) whole milk

30g (1 oz) vegetable oil

50g (1.7 oz) low protein/cake flour

  • Step 1

    Preheat a fan-forced oven to 150°C (300°F). Set up a large deep baking dish that will fit 4 x 10cm (4”) ramekins in, then place the ramekins inside and set aside.

  • Step 2

    To make the toffee, place the caster sugar into a small saucepan over medium-high heat. Keep swirling the pan around as it warms up to help you avoid burning the sugar. Keep moving it (don’t use any spoons, spatulas or any other utensil for this part) until all of the sugar has dissolved and turns a caramel colour. *Warning: you need to move quickly here! Once the caramel colour appears, turn off the heat, as the colour will continue to darken. Divide the toffee mixture equally between the 4 ramekins and leave for around 5 minutes, or until the toffee has cooled and hardened completely.

  • Step 3

    For the creme caramel, add the milk and sweetened condensed milk into a large mixing bowl. Crack in three of the eggs. With the remaining three eggs, separate the yolks from the whites into separate bowls. Add the yolks to the milk mixture as well as the vanilla paste, reserving the egg whites for later. Whisk all the ingredients together. Place a fine sieve over a large bowl, then pour the milk mixture through the strainer. This will remove any rogue parts of egg yolk from the mixture, and will help ensure the end result is as smooth as possible.

  • Step 4

    Divide the strained mixture equally between the ramekins on top of the toffee using a measuring jug or ladle. You want to leave about 2cm (just under 1”) of room between the top of the creme caramel mixture and the top of the ramekin. Set aside while you make the sponge.

  • Step 5

    For the sponge component, add the reserved egg whites and the caster sugar to the bowl of a stand mixer. Use the whisk attachment to whisk the ingredients together on high speed for 5 minutes, or until firm peaks have formed and the egg whites are marshmallowy in texture.

  • Step 6

    In a separate large mixing bowl, whisk together the egg yolks (pop the whites in the fridge for an omelette the next day), milk and oil until just combined. Add the flour and whisk again until incorporated. Now for the folding. Slowly add half of the egg white mixture to the egg yolk mixture, and gently fold through with a spatula. Repeat with the remaining egg white mixture, taking care not to over mix.

  • Step 7

    Now for the trickery. Gently spoon the sponge mixture on top of the raw creme mixture in the ramekins, dividing it equally between the 4 – it should FLOAT! Make a bain marie by filling the baking dish with water so it’s one-third of the way up the ramekins. Carefully transfer the baking dish into the preheated oven and cook for 40 minutes. Remove from the oven and leave on your benchtop for 5-10 minutes to cool slightly before placing in the refrigerator for 3–6 hours or until completely cool.

  • Step 8

    To demold the flan cakes, first pour some boiling water into the tray and leave it for a couple of minutes to warm through the toffee layer slightly. Remove one of the flans from the tray and, using a small sharp knife or palette knife, level off the top of the sponge so it’s flush with the top of the ramekin. Run the knife around the edges of the flan too. Now place a serving plate on top of the ramekin. Holding the ramekin and the plate tightly, flip everything over and lift up the ramekin to reveal the finished flan cake. Repeat process with remaining ramekins and serve immediately.
