Grind the Biscuits: Start by crushing the biscuits into fine crumbs.
Melt the Butter: Melt the butter in a non-stick pan until it's completely liquid.
Prepare the Base: In a bowl, combine the crushed biscuits with melted butter, milk, and a generous scoop of Nutella. Mix everything until well incorporated.
Whip the Cream: In a separate bowl, whip the cream with powdered sugar until stiff peaks form. This adds a fluffy texture to your roll!
Assemble the Roll: Spread the biscuit mixture onto a piece of food foil, creating a rectangular shape.
Add Whipped Cream: Evenly spread the whipped cream over the cookie mixture.
Place the Bananas: Slice the bananas and arrange them along one edge of the roll.
Roll the Cake: Gently roll the cake using the food foil, making sure the bananas stay tucked inside.
Chill the Cake: Place the rolled cake in the refrigerator for at least 2 hours to set.
Decorate: Once chilled, spread Nutella over the top for an extra layer of chocolatey goodness.
Enjoy: Slice it up, serve, and get ready for the compliments!
