Preheat the oven to 165°C.
Cut the chilled dough into 17 x 17cm blocks, roll it out, and place a sheet of Millefeuille butter on top. Roll it out using the 3/4/4 folding method. In the last folding phase, roll it out to a thickness of 2.5cm and cut into strips.
Place the strips on a baking sheet lined with parchment paper and cover with an air mat. Bake for 25 minutes.
Apply the almond cream on the first layer of puff pastry.
Add a strip of mango-passion fruit gel and a strip of liquid caramel.
Cover with the second layer of puff pastry.
Repeat the process by adding the cream, gel, and caramel, along with the crumbled praline layer.
Close with the third layer of puff pastry.
Decorate with icing sugar.
