Ah, Mary Berry. We meet again. Why must your recipes look so yummy?
So, my experience with cakey things has been a much smoother road than my overall experience with bread. Give me a cake recipe and 99% of the time, it'll go smoothly. So I wasn't really worried about this one. The only thing that concerned me was the syrupy apricot mixture that I had to make for the sandwich filling, as I tend to be a bit wary about anything that involves burning on the stove.
As it turns out, I shouldn't have worried so much. It turned out about as well as I thought it would; it was different than I anticipated, but still good. In terms of ingredients, I ended up changing a couple of them. First, I used crushed hazelnuts instead of chopped walnuts as part of the dough. Second, I used white self-raising flour as opposed to the recommended wholemeal self-raising flour, simply because the former was all that I could find. I think that these changes in ingredients might explain why the final product was more cakey than I would have assumed from the picture provided in the recipe book. Not that this was a negative point, it was just a bit unexpected.
What I would mention for those who are looking to make this, is that in spreading out the top layer of dough, I may well have displaced the apricot mixture from the centre of the sandwich bar mixture, so I ended up with a situation where I would have nothing but cake in the middle and all the apricot mixture would be pushed to the edge. As the dough is an odd kind of consistency, due to the oats that make up a portion of the mixture, it needs to be pushed out to make it fill the space correctly. So I'm not really sure how to remedy the problem.
Overall though, I would readily give the recipe another shot at some other time. I would probably change what I did a bit more, but otherwise I'm perfectly happy with this recipe. Now I just have to stop trying recipes with nuts so that I won't kill my boyfriend accidentally.
