Vanilla bean pod could also be used, or vanilla extract. My favourite brand of coconut milk.
Here, I've just added the second layer. I put it in the freezer just enough so that the first layer solidified enough to hold a second layer (approx 20 min).
For the second layer I simply poured some of the base mixture into a cup and smashed up fresh raspberries with a fork.
This would also work with regular popsicle moulds that don't have layers as the colours creates the layers (plus, as you can see my colours don't match up with the mould layers anyway!)
Always save the best till last.
