Stick 2 sheets of puff pastry together. They must still be relatively cold but not fully frozen. Pass a pin roller on top with light force, we don't want the pastry to deform just to simply stick together well. Do the same on both sides with the rolling pin.
Cut the pastry into your desired sizes, for us we cut it into pieces of about 5x8 cm giving us 15 pieces.
Place in baking tray, leaving a bit of room between each piece otherwise they will stick together and lastly stab with a fork 3-4 times.
In a pre-heated oven set to 210 C cook for 16-18 minutes until a nice golden top is reached and the pastry has risen.
While the pastry pieces are still warm slice across the middle and separate it into 2 parts.
Fill with our dulce de leche and cover!
You can sprinkle icing sugar on top to finish it off or simply eat them as they are!
