Crumb the biscuits, melt the butter and mix. Press the mixture into a pan and wrap it in aluminum foil, then place in the embers of a fire. Be careful so that it does not burn. Leave for about 7 minutes depending on the heat. Open and examine - the bottom should feel crispy. Loosely whip the cream, cut the banana and crush the Daim. Cover the cake with plenty of caramelized milk.
Then add the whipped cream and banana, and finally the crumbled Daim. Alternatively, you can make the same mix of fixed portions in, for example, SnapBoxs.
