Frosted Chocolate Marshmallow Brownies

by Laura

This Frosted Chocolate Marshmallow Brownies is recipe that I created on my own. I get compliments anytime I take these anywhere. The secret is you use a boxed brownie mix.

Now I tend to be partial to the Betty Crocker mix, but any 9 x 13 mix will do. If you really want to, you can always use your favorite homemade brownie recipe too. If you want to make them Rocky Road Brownies, add 1 cup of chopped nuts to the frosting before you pour it on the brownies.

This Frosted Chocolate Marshmallow Brownies recipe is a simple way to jazz up a boxed brownie mix. Brownies are even better topped with gooey marshmallow along with a sweet chocolate frosting.

mmm these do look good. Not sure if hubby would do the marshmallows but nuts would definitely work. Thanks for a great idea. Think I will add these to the “cookies” for the holiday table.
