Wikipedia defines coffee cakes as "A class of cakes intended to be served with coffee or for similar breaks and snacks. Under this definition, a coffee cake doesn't need to contain coffee. (although this one does) They are typically single layer cakes that may be square or rectangular like a Stollen. Coffee cakes are typically flavored with cinnamon, nuts, and fruits. Some similarity to teacakes may be found, though teacakes are often smaller individual items served with tea."
So this coffee cake definitely qualifies. It also has the added bonus of having coffee as an ingredient as well. It is also a massive cake - MASSIVE. You may want to consider baking it in 2 smaller tins and freezing one, unless you are taking it to the footy club afternoon tea or something.
INGREDIENTS. - 1/2 a lb. of butter
1/2 a lb. of brown sugar
1/4 of a lb. of golden syrup
1/2 a lb. of currants
1/2 a lb. of sultanas
1 1/2 lb. of flour
1/2 an oz. of baking-powder
1/2 an oz. of nutmeg, cloves and cinnamon, mixed
a little milk
METHOD. - Sieve the baking-powder and spices with the flour into a pan; add the sugar and butter, rub well together, make a well in the centre, pour in the syrup, add about 1/4 of a pint of strong cold coffee, break in the eggs, and beat well together; then mix in the other ingredients with a strong wooden spoon using a little milk if not moist enough, mix in the fruit last, and then bake in a long square cake-pan nicely prepared.
TIME. - From 1 to 2 hours
I have added a buttercream icing but a simple glaze would probably be better, as there is so much going on in this cake. It's very fruity and a bit gingerbready, but well worth it.
