PREPARE THE CAKE: Mix the Devil’s Food Cake Mix, Water, Eggs and Oil together, and pour into a sprayed 9x13 baking pan (or lined with parchment paper for ease in removing it from pan). Bake according to the directions on the box. Allow to cool on a cooling rack for 20 minutes.
POKE THE CAKE: Using the round handle of a wooden spoon, poke holes the cake, making the holes about an inch apart. Poke about 2/3 deep, not all the way to the bottom
MARSHMALLOW FILLING: Place Marshmallow Fluff and Water in a microwave-safe bowl. Microwave in 20-second bursts, stirring each time, until melted and blended (about 1 minute).
FILL WITH MARSHMALLOW: Pour fluff mixture into a piping bag (or a plastic bag with the corner snipped off) and pipe it into the holes. Spread remaining fluff across top. Place in the fridge to chill.
WHITE CHOCOLATE FILLING: Place White Chocolate Chips, Sweetened Condensed Milk and Cream in a microwave safe bowl. Microwave in 20-second bursts, stirring each time, (about 2-3 minutes) until melted.
COVER THE CAKE: Spread the filling over the cake, and chill until the filling is cooled completely.
WHIPPED TOPPING: Beat Cream, Confectioners’ Sugar and Vanilla with an electric mixer until stiff peaks form. Spread over the chilled cake. Garnish with Sprinkles. Chill until ready to serve.
