Instructions
- Cake
- Preheat oven to 350°.
- Whisk cocoa into melted butter until well blended. Add sugar and eggs, and either whisk or use a hand mixer. Beat in flour, salt, nuts, and vanilla.
- Scrape batter into lightly greased 13x9-inch dish and bake for about 25 minutes. Remove from oven and immediately top with miniature marshmallows. Top marshmallows with chocolate frosting.
- Frosting
- Using hand mixer, blend together 1 stick softened butter, 1/3 cup cocoa and 1 box powdered sugar. Mix in milk until frosting is smooth and creamy.
- Frosting will be thick, so just drop it over the marshmallows and then smooth out. Allow cake to cool before cutting.
