This brownie recipe came from the Great British Book of Baking, available here for £5
I have to admit, because there was some condensed milk left over from the brownies from the week prior I sort of messed with this recipe, which perhaps doesn’t make it a fair test. However, it was a good brownie: dense and sticky. It has been different from other brownie recipes, as it requires you to add in cocoa powder. This, combined with the condensed milk and cream cheese combo from the brownies from slow cooker brownies the week prior (here), made a great brownie!
