Simple, Easy Marshmallow Brownies With Brownie Frosting

Marshmallow Brownie Recipe Starring Marshmallows

These are chewy chocolate brownies with marshmallows, nuts and chocolate brownie icing, but the marshmallows are definitely the star of these marshmallow brownies.

With 2 tablespoons of cocoa in the brownie itself the brownie is chocolaty, but not an intense chocolate.  It plays much more of a supporting role in this yummy brownie production.

There are also nuts and the decadent chocolate frosting that play large supporting roles.  This brownie production would not be the rich delicious brownie treat it is without these.

However friends, the thick layer of marshmallows that are  intertwined with the chewy, nutty brownie and the splendid chocolate icing is just magnificent.  It stands out and is what makes this brownie production the indulgent treat it is. It is the star and it steals the show.

  1. Judith Bevis says:

    In the brownie could you use self rising flour and omit baking powder and salt

    1. Sorry for the late response. I would not use self rising flour in this. This messes with the leavening. If you know the exact substitutions, maybe it will be ok. I personally would not try it. Please let me know if you do and how it turns out.
