Recipe is taken from James Morton's book 'Brew'. He recommends overpitching the yeast for the most banana esters, which combining with the caramel from the malts give the Banoffee flavour. Mango Jacks description for this yeast seems to suggest that most malt character is stripped away during fermentation. We shall see. The result ought to be a very tasty beer in any case.

1.052 preboil..way off. Think this is due to my mash tun overshooting on the mash temp. Often sits above 70...
1.048 OG....1.8 litres chilled water added after boil
4 litre sparge. 2 litres tap water added during boil.
(Using new hop spider and wort level did not come up high enough to submerge the bottom of the hop spider)
20 litres into the fermentor.
Sample gravity at Day 5 yeast is a monster. Will test again on day 8.
No movement, so bottled on day 8. Sample tasted very nice. Can't to taste it after a week. Will there be banana?
1 week post bottling there was detectable banana but not loads. But a very complex and sumptuous, thick beer. Two weeks after bottling and, oh my word, this is something very special. Such a rich toffee flavour. Deep and satisfying. Perfect Xmas brew. Will definitely do again. Will rename to Toffee-bomb dunkelweizen.
