Oat and chocolate slices

    35 min

    This is a quick cake traybake that is easy to make, and big enough for a crowd. Good for school fetes or cake sales. No icing is required, as the chocolate chips and walnuts are sprinkled over top.

    Liked the idea of oats with chocolate cake but this was a real disappointment. The texture was unpleasant and none of the family enjoyed it, I'm afraid.  -  22 Jan 2013


    Thanks Cathie we loved it and we added an extra 70 g of butter too made it extra rich  -  27 Apr 2016


    Extremely easy and quick to make. I use chips only on top and bake in 9 x 13 pan.  -  16 Oct 2000  (Review from Allrecipes US | Canada)
