1 (family-size) package brownie mix
1 stick margarine
3 tablespoons cocoa
1 (16-ounce) box powdered sugar
6 tablespoons milk
Dash of salt
1 (10.5-ounce) bag miniature marshmallows
Prepare brownie mix as directed on package for chewy brownies. Bake in a 9- x 13-inch pan. While brownies are baking, melt margarine in a large saucepan over low. Add cocoa, powdered sugar, milk and salt, stirring until smooth. Leave on low heat; do not boil. When brownies are done, remove from oven and sprinkle marshmallows over top of brownies. Remove icing from heat and beat until thick. Pour over marshmallows. Cool completely. Cut into squares.
