coffee sponge cake recipe???

[glaskham]

I fancy making a coffee sponge cake with coffee butter-cream on top. Anyone know if i can just add expresso instead of water to the sponge mix?? and expresso into the butter-cream??

I used to make one with instant coffee dissolved in hot water, so I think expresso would have a similar effect (and be much nicer)

I mean, yes just use it instead of water in the cake mix, and add it to the buttercream though you'll probably need a bit more sugar than usual if you work by measuring it instead of just adding it till it seems right.
