What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 400 g dulce de leche
  • 4 pieces eggs
  • 400 ml sweetened condensed milk
  • 300 ml whole milk
  • 1 tsp vanilla extract
  • 3 tbsp white sugar

Step by step instructions

Step 1: Prepare the Caramel Base

Melt the white sugar in a small saucepan over medium heat without stirring until it turns into a deep amber caramel. Pour the caramel immediately into the base of a round flan mold and tilt to coat the bottom evenly. Allow to set for 5 minutes.

Step 2: Make the Custard

Whisk together the eggs, condensed milk, whole milk, dulce de leche, and vanilla extract until completely smooth. Pour this mixture through a fine sieve over the caramel base in the mold to remove any air bubbles.

Step 3: Bake in a Water Bath

Place the flan mold inside a larger baking dish and pour hot water into the larger dish until it reaches halfway up the sides of the mold. Bake in a preheated oven at 160 degrees Celsius for 55 to 60 minutes until just set with a slight wobble in the center.

Step 4: Chill and Unmold

Remove from the water bath and allow to cool completely at room temperature. Refrigerate for at least 4 hours or overnight. To unmold, run a thin knife around the edge and invert onto a serving plate allowing the caramel to flow over the custard.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • whole milk → evaporated milk for a richer and creamier custard texture
  • white sugar for caramel → store-bought caramel sauce poured directly into the mold to save time

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Skipping the water bath which causes the custard to crack and develop a rubbery texture
  • Not chilling the flan for long enough which causes it to fall apart when unmolding
