Death By Chocolate Poke Cake

• Butter, for greasing
• Flour, for pan
• 1 box chocolate cake mix, plus ingredients called for on box
• 1 14-oz. can sweetened condensed milk
• 1 c. semisweet chocolate chips, melted
• Chocolate shavings, for garnish

• 1 c. butter, softened
• 2 1/2 c. powdered sugar
• 3/4 c. cocoa powder
• 2 tsp. pure vanilla extract
• pinch of kosher salt
• 1/4 c. heavy cream (plus more if necessary)

DIRECTIONS

1. 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.
2. 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.
3. 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).
4. Spread frosting all over cake with an offset spatula and sprinkle with chocolate shavings.
