I use to make brownies from Duncan Hines cake mix. I think it was the butter recipe one. Now I can't remember how to make it. THe recipe was on the box for years & I guess I never saved one. I think it was 2 eggs & 1 stick of melted butter , cup of chocolate chips & 1 to 2 cups of minature marshmallows. Bake. Well I just made some & I used the regular mix & to me they don't taste good. Anybody remember.
