The recipe lived up to its promise. All the things I like in a tray cookie were there - chocolate in abundance, oats, peanuts, cinnamon, condensed milk. (Just don't think about the calories!). I picked up the recipe from here at Confectiona's Realm, and decided to halve it, as the Engineer Baker had done. I also 'translated' the quantities to metric weights, as cups make me quite uncomfortable.
Here are the weights of ingredients for a half batch (without the raisins), cooked in an 8" square tin lined with baking parchment:
Oat dough:
160g plain flour

1/2 teaspoon bicarbonate of soda
1/2 teaspoon salt
1/4 teaspoon cinnamon
115g butter
100g light muscovado sugar
1 large egg
1 teaspoon vanilla extract
150g rolled oats
75g salted peanuts, roughly chopped
Chocolate Filling:
1/2 tin condensed milk - 200g
175g plain chocolate chips
25g butter
1/2 teaspoon vanilla extract
60g salted peanuts - roughly chopped
The recipe was easy to follow, and I didn't encounter any problems with making or cooking the recipe. With hindsight, I should have spent more time and care sprinkling smaller blobs of the reserved oat dough over the chocolate filling, to give better coverage with the top layer; I expected it to spread a bit more than it did during cooking.
When it came to cutting the refrigerated cake into squares, I found the cooked oat layers to be quite crumbly, so I didn't get the really neat squares I was expecting. When I checked a similar recipe which I use for something called an Oaty Toffee Bar, I found that it used more butter in the oat dough, so that might rectify the problem in future. Or it might have been that my 'translations' to weights were innacurate enough to produce a drier dough!

I cut the traybake into 16 pieces. As with other bakes this size, it seemed a realistic estimate of the amount anyone would want to eat - however, my son ate two pieces, one straight after the other! I tried a piece from one bar cold, straight from the fridge and found the flavours very muted - neither as sweet nor as salty as I expected. The flavour improved when they warmed up to room temperature, and the chocolate fudge filling softened, but was still vaguely dissatisfying - for all the promises of the extravagent ingredients, the end result was fairly plain
and ordinary.
