When it starts to thicken, add the pineapple jam. Reserve.
Blend 1/2 box/can of condensed milk, the box/can of cream, powdered milk and powdered juice in a blender. Reserve.
Cut the cake in half or into small individual portions.
Fill with the pineapple cream.
Finish with the cream beaten in the blender.
