Fudge Brownies with Frosting
2 packages (roughly 20 oz each) brownie mix — I always use Duncan Hines Chewy Fudge 19.9 oz boxes
12 tablespoons butter, melted
1/2 cup buttermilk
2 teaspoons vanilla
1 1/2 sticks butter
1/2 cup unsweetened cocoa powder
1/2 cup milk
5 1/2 cups sifted powdered sugar
1. Preheat oven to 325. Line a 9 x 13 pan with foil. Spray bottom with bakers spray (the kind with flour in it) OR butter then flour bottom of foil lined pan. Set aside.
2. In a large mixing bowl, place both brownie mixes, buttermilk, melted butter, eggs and vanilla. Mix with a wooden spoon until fully combined. Pour into prepared pan and spread evenly.
3. Bake for about 45 – 50 minutes, until edges look set and a toothpick inserted in the center comes out with moist crumbs but not batter. Cool for at least 20 minutes, then frost.
4. Make Frosting: Melt butter in a medium sized saucepan over low heat. Whisk in cocoa powder and milk. Cook, stirring, until the mixture thickens and JUST begins to boil. Remove pan from heat and slowly add the powdered sugar, whisking until smooth. Pour over brownies and spread quickly. Let set before cutting brownies.
