- Preheat oven to 350º and butter and flour a 9″-x-13” pan. Prepare chocolate cake mix according to package directions and bake until a toothpick inserted in the center comes out clean, 26 minutes.
- Poke cake all over with the bottom of a wooden spoon. In a small bowl, mix together sweetened condensed milk and melted chocolate. Pour mixture into the holes.
- Make frosting: In a large bowl using a hand mixer, beat butter, powdered sugar, cocoa powder, vanilla, and salt. Beat in heavy cream (adding more by the tablespoon until consistency is creamy but can hold peaks).
- Spread frosting all over cake with an offset spatula and sprinkle with chocolate shavings
