Mix together the apple cider vinegar and soy milk and leave to curdle.
Add the flour and sugar to a large bowl then pour over the milk/ vinegar mix, oil and vanilla paste.
Mix well until a batter has formed.
Pour the batter into your lined tin then place into the oven at 180 C / 35 F / gas mark 4 for 25 minutes.
Remove the cake from the oven once a skewer comes out clean.
While the cake is cooling mix together the milk, cream and condensed milk for the soaking liquid.
Poke holes into the cake then pour over a third of the soaking liquid. Let this soak into the cake for 5 - 10 minutes before repeating with the next third, leaving that to soak, then finally pouring over the rest.
Leave the cake to soak up all of the liquid by wrapping it in clingfilm and placing it in the fridge overnight.
The next day, whip your cream with a little icing sugar and vanilla paste until it is stiff but spreadable.
Spread over the whipped cream.
Serve as it is, with a sprinkling of cinnamon or with fresh fruit.
