Start by adding the chocolate wafer cookies into a removable-bottom cake pan, then arrange them around the sides of the pan and set aside.
In a food processor, add the milk biscuits and grind them until they turn into fine crumbs.
Transfer everything to a medium bowl, add the melted unsalted butter and mix everything thoroughly to combine.
Next, transfer this mixture to the cake pan with the chocolate wafer cookies and spread it evenly.
In a large bowl, add the refined sugar, the whipping cream and beat everything thoroughly until it reaches a whipped cream consistency.
Add the unsalted butter at room temperature and beat once again to combine.
After doing that, divide this creamy mixture into 2 medium bowls.
To one of them, add the sweetened condensed milk and mix to combine.
Now, to the other half of the cream, add the Nutella and mix to combine again.
In the baking pan with the biscuits, add the creamy mixtures we prepared, always alternating them.
Then, using a skewer, decorate the dessert by gently swirling it across the surface a few times.
Place the dessert in the refrigerator and let it chill for at least 2 hours.
After this time has passed, to finish, add crushed biscuits to taste evenly over the top and strawberries to taste.
Serve.
