Banana and Cookie Dessert

Combine the mashed banana with the crushed cookies until well mixed.
Press the mixture into a round cake pan to form an even base.
Make the Creamy Filling:
In a saucepan, melt the butter and sugar over medium heat.
Add the sweetened condensed milk, stirring well.
Cook for about 5 minutes, stirring continuously until it thickens slightly.
Assemble the Dessert:
Pour the creamy filling over the cookie and banana base.
Slice the remaining banana and arrange the slices on top of the filling.
Decorate with Whipped Cream and Chocolate Flakes:
In a separate bowl, whip the cream with a teaspoon of fine sugar until stiff peaks form.
Spread the whipped cream over the dessert.
Sprinkle with chocolate flakes.
Serve:
Refrigerate for at least 30 minutes before serving to allow it to set.
