    If I add more melted butter will it come out more gooey when cooked???
    ________________________________________________
    Hello,

    Adding more butter will not achieve this, maybe undercooking it by a few minutes will leave it gooey in the middle.

    Hope this helps,
    Happy Baking!

    Easy to make and instructions easy to follow.
    Recipe has far too much cocoa powder and was too crumbly

    Fantastic. Baking for 20 mins leaves it soft in the muddle and crunchy on the edges. I’d say leave it an extra 5-10 mins for a crunchier finish

    Done this exact recipe but found it too hard, taste is good, would probably be better with custard.

    I used double amount of ingredients and left it in for 20 minutes...was crumbly... think it was undercooked lol di we need to leave it in oven double the time if we are using double ingredients?? 🤔

    Hi there,

    If you double up the ingredients then you will need bake for longer. I hope that this helps.

    Easy to make, but a little crumbly in places as I guess I didn't press it down firmly enough. Also way too sweet, so will definitely reduce the sugar (and maybe increase the butter a little?) next time.

    Amazing
    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.
