    Altered ingredient amounts. I felt the amount of condensed milk was too much for the oat mixture and overall too sweet. So the second time I made this, I upped the oat mixture by 50% and reduced the sugar in half. This made the bars still sticky and sweet and delicious, but less likely to fall to pieces.  -  09 Apr 2011


    Followed Jenowuk's advice and used 120g oats and 80g sugar. Also melted the chocolate to pour on top of the condensed milk so it wasn't in lumps. Use the best dark chocolate. I did chill it afterwards too.  -  27 Oct 2012
