What treat would you buy with £15?

[OldGreyBoots]

My work occasionally gives us a budget of £15 to buy ourselves something nice.
Stipulation is, it has to be edible/drinkable, and non-alcoholic.

What would you spend £15 on? (Postage can go on top of the £15 too!)

Would love some inspiration

Two really good sourdough loaves, and butter from a local dairy.

I was going to say two L'Occitaine soaps but then I read edible.

Some sourdough and local cheese

Great suggestions all round, thank you everyone! Especially loved people's specific links and brands, it's great to get personal recommendations like that
Currently torn between fudge and a trip to M&S for chocolate and cheese! But I'll be revisiting this thread each time I need some inspiration, thanks all

Also to clarify - not public sector!
We get a budget for team social events every few months, and part of the freebie is something to eat while we do our social event over a hangout online (we all WFH).
We buy it with our own money then expense it back, so not possible to sneak booze since they need the receipt.
I daresay I could argue against it and push for something inedible instead, but it's not too much of a hardship
