This is definitely, no doubt about it, a celebration cake. This isn’t something you do on a weekend to have something with tea. This is a cake to be placed at the centre of attention, shared and enjoyed.
2 teaspoons bicarbonate of soda
Preheat oven to 170 degrees
Add yogurt mixture to the flour mixture and mix until incorporated.
The dulce and ganache can be quite messy, so if you can place pieces of baking paper around the cake as you decorate, you’ll have a much easier time to get it all neat.
Add the second layer of cake, placing carefully as not to break it! Carefully smooth out any dulce on the sided, and glue any broken bits of cake back on the sides with any leftover dulce.
Spread the ganache over the sides first with a knife or spatula, then dollop a whole bunch on top and spread it out in a semi spiral fashion to get the pattern you see above.
