CRUST

 * 1 box yellow cake mix
 * 1 stick unsalted butter melted
 * 1 large egg

FILLING

 * 8 oz block cream cheese softened
 * 2 large eggs
 * 1 stick unsalted butter melted
 * 1 tsp vanilla extract
 * 3 3/4 cups powdered sugar
 * 1 cup semi-sweet chocolate chips

Directions

 * 1) Preheat oven to 350F degrees.
 * 2) Spray a 9x13 baking pan with nonstick cooking spray.
 * 3) For the crust: In a medium bowl, combine cake mix, melted butter and egg. Beat together using an electric or stand mixer on low for 2 minutes. #You'll notice the batter will start to pull away from the sides of the bowl.
 * 4) Spread the batter into the bottom of your baking dish. It's best just to get in there with your hands to get it all evenly spread out.
 * 5) For the filling: Using the same mixing bowl, add the cream cheese and beat on low until smooth.
 * 6) Add the eggs, melted butter and vanilla extract and mix on medium speed for 1 minute.
 * 7) Add in the powdered sugar and mix everything together until smooth and well incorporated.
 * 8) Place 1 cup chocolate chips into a microwave safe bowl or dish. Microwave chips on high for about 1 minute (maybe longer depending on your microwave). Stir chips to make sure they all melted.
 * 9) Measure out 1 cup of the cream cheese filling. Combine cream cheese filling with melted chocolate. Whisk together until well blended and all one color.
 * 10) Pour filling on top of crust and spread out evenly.
 * 11) Using a spoon, dollop chocolate filling on top of cream cheese filling.
 * 12) Using a butter knife, swirl the knife around so the top of the batter has a marbled effect.
 * 13) Bake for about 45 minutes. Be careful not to overbake.
 * 14) Cool for at least 30 minutes.
 * 15) Then cut into squares and serve.
