Hi Tammy
Usually flapjacks and hobnobs [which I am making tonight] don't set because the syrup/sugar hasn't been heated enough when melting. I usually melt mine and let it bubble a bit before adding the oats etc.
I've never had a batch crumble on me; but if you do it too much it does tend to go a little more solid.
I also cut mine in the tin and leave until cool; rather than take them out before cool. |
