Melt the butter in the microwave on short bursts on in a small pan over a medium heat.
Blitz the biscuits in a food processor to a small crumb, add the butter, and pulse a few times until it is combined well. Tip into a 8″/20cm deep springform tin and press down firmly – chill in the refrigerator whilst you do the rest!
For the Cheesecake Filling
Melt the two chocolate’s in a bowl over a pan of gently simmering water, stirring gently or microwave in short bursts until fully melted – leave to cool slightly whilst doing the rest.
With an electric mixer (I used my KitchenAid) mix the cream cheese, icing sugar, vanilla, and malt powder until combined – pour in the melted chocolate and whisk again till combined.
Then, pour in the liquid double cream and continue to whip the cheesecake mixture until it is starting to thicken a lot like a mousse does!
Pour the mix on to the biscuit base, smooth over, cover, and chill in the fridge for at least a few hours hours or overnight.
For the Decoration
Remove the cheesecake from the tin, and spread the melted malteser chocolate on top.
Whip together the double cream, and icing sugar and pipe on using a 2D closed star piping tip, add some Maltesers, and some more crushed Malteser’s.
Notes
If it looks like your cheesecake isn’t setting, or its a but sloppy, or you’re even not sure.. try it anyway. Try to set the mix anyway! If it still doesn’t set, freeze it and have an ice cream cheesecake!
You could easily use mascarpone instead of the Philadelphia if you wish, but make sure its 500g worth, and use the full fat version.
I always set my cheesecakes in the fridge overnight otherwise they risk being a little runny still and slipping off the biscuit base but if you want to risk it then go for it! If you think its not setting, 99% of the time its because you didnt whip it enough!
This cheesecake will last covered in the fridge for 3 days!
This recipe has been updated since the original post – the original base was 150g oreos, and 150g malted biscuits if you still wanted to make it that way.
