Notes

The plum streusel cake can be served warm or cold. For that extra indulgence, serve with cream, yogurt or ice cream.
Notes:
  1. Once you have a coarse bread crumb texture if you take a small handful of the crumbs and squeeze lightly you can produce small clumps that toast up wonderfully in baking.
  2. Placing the topping in the fridge allows the crumb maintain its texture.
  3. Ensure you leave an overhang of parchment paper to allow you to lift out the cake.
