Slow cooker treacle sponge

I wish I had taken a photo of it to show you because it looked fantastic. Quite some time ago I had a go at baking in my slow cooker. I made a lovely carrot cake that was deliciously moist and scrummy. It got me thinking about using the slow cooker for a steamed sponge. The idea being you could just put it in and basically forget about it. Last Sunday we had the mother - in - law for tea. I cooked a lovely lasagne which she loves and I made a treacle sponge and custard for pudding. Here is the recipe:-

100g of Self raising flour
100g of margarine
100g of sugar (I used brown)
loads of golden syrup (sorry I didn't measure it)
2 eggs

I blitzed the flour, margarine, sugar and eggs in the food processor.
I greased a pudding basin with margarine and then poured about an inch of golden syrup into the bottom. I then piled on the sponge mixture. Covered tightly with a piece of pleated foil and then put into the bottom of the slow cooker. I put about 3-4 cm of water in the bottom of the slow cooker. Put the lid on and turned on high. I checked after about 3 hours to find it cooked right through. It was light and fluffy and very moist. I turned it out onto a serving dish and the golden syrup ran down the sides. It was a big hit with everyone.
