A friend sent me this recipe after I'd arranged a few weeks ago to meet up with him to hear all about his life. The evening came and he definitely hadn't forgotten the brownie and salted caramel delights he had messaged me about. Of course we made them, and of course they were everything we had hoped they would be (and more). Sure, one bite and you know any healthy eating you have ever done in your life EVER is ruined, but they are so flipping delicious who cares! They're rich and sweet as well so that you really can only eat one cookie sandwich at a time. Which I can assure you in these circumstances is a good thing. You'll get about 14 sandwiches (i.e. 28 brownie circles) out of this recipe, so if you don't fancy sandwiching them together (which is magic, so why wouldn't you) you do end up with a lovely big batch of soft and chocolatey brownies. To make brownie and salted caramel cookie sandwiches you will need: 1/2 cup of salted butter...
