I apologise in advance for the lack of photos today - it was an experimental bake, so I concentrated on getting it done rather than getting shots of each step, but it's really very straightforward, I promise! I'll get pictures the next time I make it, but for the moment you'll have to use your imagination, okay folks?
I made this with a couple of handfuls of blackberries that we had left over, but it would be good with any berries (or combination of berries), apple, pear, or gently stewed (and then drained) rhubarb. Ooo, or tinned peaches... that would be great too! You want 80g-ish, and if you're using something out of a tin try to add as little of the juice/liquid as possible, otherwise you'll end up with very soggy sponge.
equal weight of marg
equal weight of sugar
equal weight of plain flour
one tbsp baking powder (stir this into the flour)
two tsp vanilla extract
a couple of handfuls of blackberries (very approximately 80g)
a pint of custard (this needs to be pretty thick so best not use instant as it would be too thin. I use a bit more custard powder than it says, so it'll end up thicker)
- Turn on your oven - I set my fan oven to 180°c.
- I use a 25 x 25cm loose based (square) tin, which is about right for this amount - it's deep enough that you get a proper piece of cake but not so deep that you end up burning the top to make sure the sponge underneath is cooked.
- Line the tin - you won't be able to get it out after it's cooked by turning it upside down, so make sure you'll be able to lift it out!
- If you're making custard then do this, or open the tin if you're going that route.
What to do
Beat sugar and marg til pale and fluffy
Continuing to beat, add the first egg and vanilla extract, then a tbsp of flour if it starts to curdle. Add the next three eggs the same way
Fold in the flour
Spoon approximately two thirds of this mixture into the (lined) tin, covering the bottom. Spoon a little extra around the edges
Put your blackberries on top, or whatever fruit you're using - try and spread them out, but this need not be terribly precise - just get them on there! Try to avoid the very edges, where the mixture is thicker
Custard time . . . a tablespoonful at a time, put the custard on top - again, try not to put any right at the very edge. Don't worry if it looks kinda blooby, it doesn't have to be even - in fact, it's better if there are gaps where you can still see the sponge mixture through
Spoon the remaining sponge mix on top - there probably won't be enough to cover all the custard - again, this is fine, I promise!
Get your tin in the oven, make yourself a cuppa and sit purself down to enjoy it. Check your creation after 25 minutes, but it may need a little longer depending on your oven and the size of your tin
Leave your blackberry custard cake in the tin to cool - if you can resist, leave it alone till its just warm, then de-tin it and have a taste!
