I have a request to make Coffee and Walnut cake (to take into the office next Tuesday 14th). But I have noticed that the people in the office are not so keen (these days) on gathering round a cake to cut slices - a bit too "hands on" I guess? (Germophobia) So, I plan to make Coffee and Walnut Cup Cakes with cream cheese frosting. And so far, it seems the best way to get a really good coffee flavour into the sponge is to use instant Espresso Powder. Seems good to me. But any other suggestions? (I have tried making "proper" coffee with my Cafetiere, but actually got pretty weak results.)
