I was hoping for the cake to take on the purple tinge of the yoghurt but, as you can plainly see, it didn’t. What I didn’t expect – and what turns out to be the true joy of this cake – is that the sponge tastes of blueberry….
…let me clarify: the sponge itself tastes of blueberry. Normally in such a cake, the sponge tastes of sponge and you get the burst of blueberry in your mouth when you bite into a blueberry. However, with this cake, the flavoured yoghurt has infused the sponge resulting in the most wonderfully fruity tasting cake. I loved it.
275g caster sugar
1 teaspoon vanilla extract
175g Greek style yoghurt – I used blueberry flavour
275g self raising flour
1 teaspoon bicarbonate of soda
130g fresh blueberries
2 tablespoons light brown sugar to sprinkle on top of the cake
