(luckymommyto2boys ~ Amy ~ via Little Kitchie)

for the cake, you'll need:
1 box chocolate cake mix (I used Duncan Hines Dark Chocolate Fudge Cake Mix)
1 large egg
8 tablespoons unsalted butter, melted

for the filling, you'll need:
8 oz. cream cheese, softened
1 cup Nutella
3 large eggs, beaten
1 teaspoon vanilla
8 tablespoons unsalted butter, melted
2 cups powdered sugar

Preheat oven to 350 degrees F. Spray a 13x9 pan with cooking spray.
Add cake mix, egg, and butter to the bowl of an electric mixer and mix until completely incorporated. Use your fingers to press into the bottom of the prepared pan.
Clean the bowl, then add cream cheese and Nutella and beat until smooth. Add the eggs, vanilla, and butter. Beat on low until incorporated, then slowly add the powdered sugar and beat until smooth. Add to the pan and evenly spread over cake batter.
Bake for 40-45 minutes. Allow to cool completely, then dust with powdered sugar. If desired, top with fresh whipped cream. Aaaaaaand devour.
