Yogurt in Spruced Up Vanilla Cake

Our answer

Nigella's Spruced Up Vanilla Cake (from Christmas and on the Nigella website) uses fat-free (non-fat) natural (plain) yogurt. This adds moisture to the cake and the acidity of the yogurt also helps to make the cake tender. Fat-free yogurt contains only trace amounts of fat (usually about 0.1%). Regular natural yogurt typically contains 1.5% to 3% fat (Greek yogurt will be higher), depending on whether it is made with semi-skimmed (reduced fat) or whiole milk.

The cake contains 250g (1 cup) of yogurt so the amount of fat added from using a regular natural yogurt is small and the regular yogurt should work in the cake. Buttermilk is also low fat and could be considered as another alternative.
