In a saucepan, melt the butter over low heat. Roughly chop the walnuts and crumble the biscuits into small pieces. Finely chop the pitted dates to ensure easy mixing.
In a mixing bowl, combine the melted butter, chopped walnuts, crumbled biscuits, and chopped dates. Add the chocolate drops and mix everything thoroughly with your hands until evenly combined.
Firmly press the mixture into a pie pan with a removable bottom for easy removal. Generously sprinkle shredded coconut on top. Refrigerate for at least 2 hours to set before serving.
