"Re: Brownie Mallow Bars

The recipe was easy to follow, but I found it very difficult to cut after being in the refrigerator ( the marshmallow layer was extremely hard)

"I have to say i love these brownies. Although I hope she did not take credit herself I have been making these brownies for years. I got the recipe from and old "bake Sale" book. It really upsets me that someone would take the credit for someone elses work! So I hope she is not!
