Keep an eye on these and use your best judgement.
Going into this I was concerned about the long cook time at a high heat. To play it safe with my fan oven, I reduced the heat to 180C and checked on my brownies at the 20 minute mark. I wobbled the pan and there wasn't much wobble and my biscuits on top were catching so I took it out. They weren't gooey, more crisp once cooled but still nice and sweet with the biscoff and large amount of chocolate.
Not sure I would do THIS recipe again.
FYI - I used the pan size required
