While cake is baking, make the filling π
Into a pot, pour milk, sugar, and coconut, bring to light boil, stirring often. While doing so, in a cup, mix milk and pudding powder. Once mixture in the pot started to simmer, pour in pudding mixture, take off from heat.
Let cool completely and then chill in the fridge for at least an H
Once cake is cooled and coconut filling is chilled, turn heavy cream into whipped cream, then mix it into chilled coconut filling.
Lay a cake, spread some cream, top with almonds, then lay another cake, repeat steps once more, then top with the last layer. Cover cake with cling wrap, chill overnight.
Store leftover to use to finish decorating the cake the next day.
