Baking a cake with no scales

[HastingsLikeTheBattle]

Can anyone give me a fool proof recipe for a basic sponge that I can make with no scales please? I have some cup measurementsfree with good housekeeping but I don't know how much of each?

Google 'yoghurt pot cake' - no scales required, just a yoghurt pot.

I don't have scales either, I just google 'how many tablespoons equal 4g' or whatever the amount is.

All American recipes use cup measurements, so I'd look out for those.

Basic sponge are usually equal quantities of flour, butter and sugar.

Couldn't live without my scales! I panic when the battery gets low
