In a skillet over medium heat, melt the marshmallow.
Next, add the Ruffles potato chips and stir until incorporated.
Turn off the heat, add the rainbow candy-coated chocolate chips and stir once again until incorporated.
Transfer all this mixture to a removable-bottom cake pan greased with coconut oil and spread it evenly until flat.
If you prefer, grease your hands with coconut oil and use them to spread the mixture.
Add the hazelnut cream and spread it well until flat.
Take it to the freezer and let it chill for 40 minutes.
After this indicated time, add a mixture made with the melted white chocolate and the table cream and spread this mixture all over the pie.
Top it with another 250g of marshmallows, and if you like, roast them with a blow torch.
Take it back to the freezer and let it chill for another 15 minutes.
Serve.
