First, prepare the pastry: pour all the ingredients into a bowl and knead quickly, just long enough until you get a homogeneous dough.
Wrap it in plastic wrap and let it rest in the fridge for at least 1 hour.
Take the dough back and divide it into 2 parts (one slightly larger than the other).
Roll out the larger half in a rectangular sheet not too double and use it to line the mold lined with parchment paper.
Cover the bottom with Kinder bars.
Roll out the second part of the pastry and use it to cover the bars, sealing the edges with the pastry below.
Cover the surface with the chocolate chips, then bake in a preheated convection oven at 180 ° C and bake for about 20 minutes or until golden brown.
The tart with Kinder bars is ready: let it cool completely, then cut it into squares and serve.
