These cakes are amazing Jess! Those flavours are making me drool. I love your attention to detail...and the house mascots are so incredibly cute.

As for pumpkin puree in the UK, that only place I can find it with any regularity is in larger Waitrose stores. It's only £2 or so per tin, so I always stock up when I'm nearby (I've a pumpkin pie obsessed other half!). I've also seen Tesco do it online near to Thanksgiving, and Amazon do it if you don't mind buying in bulk.
