marshmallow brownies

here's the recipe i used to make the brownies in the above picture. it is my mom's  and one of my favorite indulgences.

1 c. butter, melted
1/2 c cocoa powder
2 c. sugar
4 eggs
1 1/2 c flour
2 t. vanilla

beat butter, cocoa and sugar until well mixed. add eggs one at a time, beating after each one. add flour and vanilla and pour into greased cake pan. bake at 350 degrees for 25 min, remove from oven and sprinkle 1 lb of marshmallows on top, bake for 5 more min. cool completely and then frost.

frosting:
1/3 c. cocoa powder
2 c. powdered sugar
1/3 c. canned milk
1/4 c. softened butter

combine all ingredients and whip until smooth. recipe is quite runny, but hardens after sitting. (i usually add 1/2c-1c more powdered sugar.)

let sit after frosting several hours before cutting
