Not just you.. been puzzling that one for a week now... can only think that the people inventing the advert have never baked a cake... either that or flour sugar and eggs should all be stored in the fridge and I have got it wrong for half a century...!!!
I know,this ad kills me every time! Bet everybody turns to who ever's beside them and says "what's this got to do with baking a cake"? It's a total embarrassment for the company !
