I don't really make desserts and only cook a bit here and there but can vouch for this recipe. Most technical things you need to do is melt chocolate (microwave cheat here lol) and whisk the cheese and cream! Add 150g of biscuits instead of 100 for the base to make it a bit more substantial and maybe a bit less chocolate on top as 100g feels like too much.
Recipe here and enjoy if you get to make/eat it!
