2 1/2 cups self raising flour
3/4 cup golden syrup
1 cup sugar
2 tsp baking soda
2 tsp cinnamon
3 tsp ground ginger
3 tsp mixed spice
Oven - 180°C (NOT fan-forced)
Place butter, milk, syrup & sugar in a large saucepan, bring almost to the boil. It's a good idea to stir more or less constantly, to avoid burning the sugar & syrup. Add the salt & baking soda, stir well. When the mixture is frothy, turn off the heat, sift in the flour & spices, & stir until combined. Bake for approx. 45 minutes.
The sugar in the crust will caramelise, giving you a shiny, crunchy crust over a surprisingly firm-but-soft inside. I've only ever baked this in my good cake tin; 45 minutes gives you a ginger-bread-y cake that's springy & has an almost honeycombed texture at the edge, but stays pretty gooey at the centre. In a normal cake tin, it's impossible to get the centre cooked through without burning the edge, and since I like the changing texture anyway, I don't mind.
If you do mind, try experimenting (honestly, it's fun!). Best bet for even texture is probably a ring cake tin, the kind that look like a giant doughnut; spreading the batter across a slice tin will probably give you something more gingerbread-y, and I'm not sure what baking it in a loaf tin would do. Probably the centre would still be a bit gooey, but less than with a traditional cake tin.
In terms of recipe experimentation - a small handful of currants make an awesome addition, and it could probably take walnuts, too. Last night I discovered we had no ginger, so I used cumin instead - awesome variation, and I'll bet ground coriander'd be pretty damn tasty too. I also tend to be kinda freehand with adding the spices, the batter never quite tastes like I want it to.
Warm, this goes really well with thick custard, cream, icecream, whatever. A yoghurt-based sauce would probably suit it well, too. It really doesn't need any help on the sweetness, though. It's also an excellent accompaniment to tea or coffee.
...also the cats really like it, but they don't get any. Nyer nyer...
Go forth & bake!
