Banana Pudding Pie

First, prepare the pudding: Pour 400 ml of milk into a medium-sized pot and bring it to a boil over medium heat. Meanwhile, whisk the pudding powder into the remaining 100 ml of milk. Then pour the resulting mixture into the boiling milk, add 30 g of sugar, and stir constantly for 1⁠–⁠2 minutes until the mixture thickens over medium heat. Afterward, remove the pot from the heat and let the pudding cool.

Preheat the oven to 180 °C and prepare a round cake pan with a diameter of approximately 22 cm, lining it with baking paper.

Place the pre-rolled puff pastry into the pan in such a way that it covers the entire bottom and also extends up the sides of the pan by approximately 3 cm.
