Oreogasm Poke Cake

Preheat oven to 350º and grease 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, about 25 minutes. Poke cake all over with the bottom of a wooden spoon. In a small bowl, microwave marshmallow crème and water, then stir until smooth. Stir in ground Oreos, then pour all over cake, making sure to fill the poked holes. Make frosting: in a large bowl using a hand mixer, beat heavy cream, powdered sugar and salt until medium peaks form. Fold in 1/2 cup crushed Oreos. Frost cake with the whipped cream and sprinkle with the rest of the crushed Oreos. Top with halved Oreos and drizzle with chocolate sauce. Serve.
