Quick help needed, what's the fastest way to soften butter to make a cake?

[Jippers]

I've suddenly developed a need for cake.. Only my butter is rock solid. I can't wait all evening for it to soften. It likely wouldn't anyway because my heating isn't on. Will it be enough if I grate it? I know microwaving isn't any good. Those who give tips can have a slice when it's ready...

Cut up small, and 7 seconds in the old microwave. Not sure on the new one.

I once saw a tip on TV (I think hairy bikers) where he put the butter in his armpit to soften it … 🤣

I have now eaten the cake... I feel so much better.. 😁

If you read the opening post, I have no heating!

Was it good? What sort?

Glad it hit the spot.
What did you do to soften the butter in the end?

Next time, just make brownies.

Melt your butter in the microwave and none of that tedious creaming stage.

My best banana cake recipe involves melting the butter in a pan with the sugar.
