If you find yourself running out of time to make a cake in time for your DH to arrive home from work, for example you may have spent the day beating the rugs outside or getting in a wrangle with the mangle, or it may just be that you underestimated the time it would take to fix your hair as the curls weren't properly taking. (Tip for next time - egg white).
Finally your attention turns to the cake you promised, only to discover you are out of self-raising flour and there isn't time to pop to the grocers. Fear not, it's easy to make your own! Everyone has plain flour and baking powder in the cupboard, all you have do is combine plain flour with some baking powder and it magically turns into self-raising flour. I know! How come my Grandma didn't tell me that!
Anyway, as I was saying. You will have some jars of strawberry or raspberry jam left from your summer jam-making (happy days!), so I suggest a simple Victoria Sponge, with your home-made jam sandwiched deliciously between two perfect golden spheres.
Oh your DH is in for a treat! And maybe you are too later, OP! Having charmed him with your freshly done hair and make-up, why not pop a cherry on top? I would!
