Start by placing the cocoa powder into the sweetened condensed milk, mix everything very well until the cocoa dissolves completely and set aside.
Next, in a mixer, add the cornstarch biscuits and grind them until they turn into crumbs.
Transfer everything to a large bowl, add the unsalted butter and mix to incorporate.
In a large bowl, add the whipping cream and beat it until it turns into whipped cream.
Add the sweetened condensed milk we prepared and beat again until combined.
Next, chop the semisweet chocolate and the hazelnuts into smaller pieces.
Into the cream we prepared, add the chocolate, the chopped hazelnuts and mix to incorporate.
To assemble the dessert, place ⅔ of the butter-and-biscuit mixture into a medium dish and press it firmly into the bottom.
Add the cream we prepared and spread it.
Take the dessert to the refrigerator and let it chill for at least 3 hours.
Finish with the remaining ground biscuits.
Serve.
