One Bowl Irish Mint Walnut Brownies

Rose Mary Mogan


I am posting this recipe especially for Jenny. I recreated this recipe a few years ago originally from a Bakers Chocolate recipe. I added a few items and changed a few other items to pay tribute to my husbands Irish heritage, and he and everyone else really liked them. They were moist, chewy, minty and nutty. The cream cheese minty frosting is an added bonus. You can make your own as I did here or buy the canned variety, & add peppermint extract to the canned frosting. I personally prefer to make my own, it is just as easy.I usually make this especially for St Patricks Day. Keep refrigerated
