Mix the crushed biscuits or cookies with the melted butter and optional milk until combined. Press firmly into a glass dish to form the base.
In a bowl, stir together the caramel protein pudding, peanut butter, and chopped peanuts. Add honey if you want extra sweetness. Spread the filling evenly over the base.
Heat the heavy cream until hot. Pour it over the chocolate pieces, let it sit for 30 seconds, then stir until smooth.
Pour the chocolate topping over the filling and spread evenly.
Refrigerate for 1 to 2 hours, or until set.
Slice into squares and serve.
