    Although after reading the reviews I choose to tweek it slightly.
    I used Cadbury’s FREDO hotchoclate, a teaspoon of baking powder and an extra splash of milk to Combine the mixture slightly more but not completely.
    Also baked it at 160degrees for a couple of mins longer untill I was happy with it.
    And the finished product was amazing 👌🏻

    I found this was a good recipe and it looked exactly like the site photo above including the crumbs.. The grandchildren enjoyed this just as much with custard as without. No doubt it will become a favourite. It had a lovely chocolate taste which the kiddies loved, yet some older members of the family said it was a tad too much for their tastebuds.
    I used Bournville cocoa so if you know that others may prefer less of a chocolate taste I suggest using a different brand. I would bake this again as it's a quick and easy traybake to make.
