Since I made game about running a café (https://smurjo.itch.io/s-caf-am-markt), I might be able to help with various cakes, plates, cups and fork. I don't have a coffee machine. Have a look here
and tell me whether it's the style you are looking for. I would make a downloadable asset-pack for you if you kindly mention me in the credits.
I guess it is understood that you can't sell my assets which I would give you for free. Nor do I approve their use for training AI.
