Mousse cakes make a great birthday cake, and it’s so versatile taste-wise, you can make it different every single time.
This cake is for halva lovers – a thin honey and pecan crust topped with honey and halva mousse that is really easy to make, and lots of pecan streusel on top.

Honey and halva mousse:
