Notes & Substitutions
Selecting quality box mixes ensures the best results for your Midnight Fudge Cake. We recommend using the specific flavors listed for optimal taste.
- Box Mix Selection: Use a high-quality ultimate fudge brownie mix and a triple chocolate cake mix for the deepest chocolate flavor. Any reputable brand works well.
- Oil Alternatives: You can substitute vegetable oil with other neutral oils like canola or melted coconut oil. Applesauce is a healthy alternative, but it may slightly alter the texture.
- Egg Temperature: Bring eggs to room temperature before mixing. This helps them incorporate better and creates a smoother batter.
- Understanding the science behind baking with room temperature eggs can enhance your results, as they blend more evenly and help batters rise better, according to sources like America’s Test Kitchen.
- Hot Fudge Topping Options: While jarred hot fudge is easiest, you can also use a homemade chocolate ganache for an extra luxurious finish.

You don’t need fancy tools to make this fantastic Midnight Fudge Cake. Just grab these common kitchen items:

- Large mixing bowls
- Electric mixer (optional, a whisk works too)
- Measuring cups and spoons
- Rubber spatula or spoon
- Sharp knife for swirling
- Cooling rack
Instructions

Follow these simple steps to create your incredibly moist and flavorful Midnight Fudge Cake. These instructions ensure a perfect result every time.
- Preheat Oven & Prep Pans: Preheat your oven to 350°F (175°C). Generously grease and flour two 9×13 inch baking pans to prevent sticking.
- Prepare Brownie Batter: In a large mixing bowl, combine the ultimate fudge brownie mix according to package directions. Add half of the water (¾ cup total for two mixes), half of the vegetable oil (⅜ cup total), and two of the large eggs. Mix the ingredients until they are just combined, being careful not to overmix the brownie batter.
- Prepare Cake Batter: In a separate large bowl, combine the triple chocolate cake mix according to its package directions. Add the remaining half of the water (¾ cup), remaining half of the vegetable oil (⅜ cup), and the last two large eggs. Mix this until just combined and smooth.
- Layer Batters: Pour half of the prepared brownie batter evenly into each of your two greased and floured 9×13 inch pans. Next, carefully spoon half of the prepared cake batter over the brownie layer in each pan. Try to distribute it evenly.
- Swirl for Marbling: Gently insert a sharp knife or a skewer into the batters. Swirl through the layers to create a beautiful marbled effect in your Midnight Fudge Cake. Do not overmix; just a few gentle swirls are enough.
- Bake Cakes: Place the pans in your preheated oven. Bake for approximately 35 minutes. Check for doneness by inserting a toothpick into the center of the cake; it should come out with moist crumbs, not wet batter.
- Cool Cakes: Remove the pans from the oven and let the cakes cool in the pans for about 20 minutes. After this initial cooling, carefully invert them onto wire racks to cool completely. This ensures the cake doesn’t stick and retains its shape.
- Heat Fudge Topping: While the cakes cool, prepare your hot fudge topping. Scoop the jarred hot fudge into a microwave-safe bowl. Microwave it for short intervals, stirring in between, until it becomes warm and easily pourable.
- Drizzle and Serve: Once the Midnight Fudge Cake layers are completely cool, generously drizzle the warm hot fudge topping over both cakes. You can use the entire jar for maximum indulgence. Slice and serve immediately for a truly decadent treat.
Pro Tips & Troubleshooting
Achieve the perfect Midnight Fudge Cake every time with these helpful tips and tricks.
- Don’t Overmix: Overmixing develops gluten, leading to a tough cake. Mix wet and dry ingredients just until combined for a tender crumb.
- Proper Pan Prep: Always grease and flour your pans thoroughly. This prevents sticking and ensures your cake releases easily.
- Perfect Swirl: Use a gentle hand when swirling the batters. Over-swirling can muddy the layers, losing the beautiful marbled effect.
- Cooling Completely: Ensure the cakes cool fully on racks before drizzling the hot fudge. Warm cake will melt the fudge, creating a mess rather than a neat topping.
- Heating Fudge: Heat the fudge topping just until pourable, not boiling hot. This makes it easy to drizzle without making it too thin.
- Doneness Test: A toothpick should come out with moist crumbs, not liquid batter. Over-baking can result in a dry cake.
