1 tin (380 ml) of caramelised condensed milk.
300 ml fresh cream. It should be well chilled.
1 packet (200 gram) Tennis biscuits (you won’t need all of it, but don’t sneak away too many while building the tart, else you may run into trouble.)
2 x bars (49 gram) Peppermint Crisp chocolate. You can use more if you have a particularly sweet tooth.
Line a small loaf pan with aluminium foil.
Now line the bottom of the pan with Tennis biscuits. (The bottom of our loaf pan measures about 19 cm x 8 cm and takes three biscuits.)
Whip the cream until stiff, and gently mix the caramelized condensed milk into the cream. Don’t worry about a perfect mix, steaks of caramel look good once you cut it into slices.
Chop the Peppermint Crisp bars and mix into the cream-and-caramel.
Spoon 1/3rd of the cream mixture over the Tennis biscuits. Add another layer of biscuits, and cream mixture, until you have three layers of cream sandwiched between four layers of Tennis biscuits.
Place in your freezer. It needs be, overnight is best.
Remove from the loaf pan and slice.
Some recipes suggest that you leave it outside for a few minutes before serving, but we found it easy to cut slices with a heavy knife directly out of the freezer.
