Ingredients
Main Ingredients:
- 1 box German Chocolate Cake Mix
- 3 large eggs
- 1 & ⅓ cup water
- ⅓ cup vegetable oil
Supporting Dry Ingredients:
- ⅔ cup sweetened shredded coconut
- ⅔ cup semi-sweet chocolate chips
- ½ cup chopped pecans
Cream Cheese Topping:
- 8 oz cream cheese
- 1 stick (½ cup) unsalted butter
- 1 pound powdered sugar
Instructions
- Coat a 9 x 13-inch baking pan with non-stick spray. Scatter ⅔ cup coconut, ⅔ cup chocolate chips, and ½ cup pecans across the bottom, creating a textured base layer.
- Mix the German chocolate cake mix with ⅓ cup vegetable oil, 3 large eggs, and 1 & ⅓ cup water in a large bowl. Blend thoroughly until the batter appears smooth and consistent.
- Gently pour the cake batter over the coconut, chocolate chip, and pecan layer, ensuring an even distribution across the pan.
- Melt 1 stick of unsalted butter and 8 oz cream cheese together in a saucepan over low heat, stirring until completely combined and silky.
- Gradually incorporate 1 pound of powdered sugar into the butter-cream cheese mixture. Whisk until the topping becomes creamy and uniform in texture.
- Drizzle the cream cheese mixture across the cake batter. Use a knife to create gentle swirls, creating a marbled appearance.

Notes
- Chill the cake briefly for cleaner slicing if the cream cheese layer seems too soft when first out of the oven.
- Swap pecans with walnuts or almonds for different nutty flavor profiles if allergies or preferences require.
- Use a low-fat cream cheese and sugar substitute to create a lighter version of this decadent dessert.
- Check the cake at 35 minutes to prevent potential over-browning, as oven temperatures can vary slightly between models.
