Hershey's Special Dark Snack Cake Medley

Preheat oven to 350°F (175°C).
Grease and flour a 13x9x2-inch baking pan.
Prepare the Cream Cheese Filling:
Place chocolate chips in a small microwave-safe bowl.
Microwave on HIGH (100%) for 1 minute, then stir.
If needed, microwave an additional 15 seconds at a time, stirring after each heating, until the chips are melted and smooth.
In a medium bowl, beat the cream cheese and sugar until well blended.
Add the egg and vanilla, mixing until smooth.
Pour in the melted chocolate and beat until fully combined.
Set aside.
In a large bowl, stir together flour, sugar, cocoa, baking soda, and salt.
Add water, oil, eggs, vinegar, and vanilla.
Beat on medium speed with an electric mixer for 2 minutes until well blended.
Pour 3 cups of batter into the prepared baking pan.
Drop the Cream Cheese Filling onto the batter by heaping teaspoonfuls.
Carefully spoon the remaining batter over the filling.
In a small bowl, combine chocolate chips, coconut, and chopped nuts, then sprinkle evenly over the top.
Bake for 50-55 minutes or until a toothpick inserted into the center comes out almost clean, and the cake starts to crack slightly.
Cool completely in the pan on a wire rack.
Cover and store any leftovers in the refrigerator.
