Start by cutting the disc of puff pastry into 7 circles and prick the entire pastry with a fork.
Place in a preheated oven at 180° C (350° F) and bake for 20 minutes.
In a large saucepan, add the egg yolks, the sugar, the cornstarch, the milk and stir everything very well until dissolved.
Turn on the heat to medium-low and continue stirring until thickened.
Then, turn off the heat, add the heavy cream, the vanilla extract and stir until combined.
Transfer to a medium bowl, add the sweetened condensed milk and mix to incorporate.
Set aside until it reaches room temperature.
Once the pastries have baked, fill them with the cream we prepared.
Place in the refrigerator and chill for at least 30 minutes.
After this time has passed, to finish, sprinkle powdered sugar over everything.
Serve.
