Preheat the oven to 240°C.
Tightly roll up one sheet of Puff Pastry, then roll up another sheet around it continuously to make a log. Slice into 12 discs.
Grease muffin cups if required. Flatten each pastry disc with your hands, form into a cup shape, and place into each cup. Press and stretch the pastry to cover the cup to the top, making the pastry evenly thin.
Make custard. Place Egg Yolks, Vanilla Extract, Sugar & Flour in a saucepan and combine well. Add warmed Milk and mix well. Cook over a medium to low heat, stirring constantly, until custard thickens.
*Note: The custard can be made in the microwave. Place all ingredients in a heat-proof bowl and whisk well to combine. Then cook in the microwave, occasionally whisking, until the mixture thickens.
Pour the custard into each pastry cup. Place in the oven and bake for 10 to 15 minutes or until pastry is golden and crispy, and the custard is browned.
*Note: Every oven is different, find the right temperature and cooking time for your oven.
Leave to cool in the muffin tin for 5 minutes then move to a cooling rack. Sprinkle some Ground Cinnamon on top if you like, and enjoy cold or warm.
