These are the best no bake brownies I have ever had. Full Disclosure, I put 2 tablespoons of simple syrup instead of water in the dough and a dash of simple syrup in the frosting.
So awesome. I could eat the whole pan.
Quite tasty, but I prefer these warm and the frosting tasted a bit too maple-y for me. Maybe you just have to make sure the quality of your syrup is high.
