Ingredients Notes

The magic of this Midnight Fudge Cake lies in its carefully chosen ingredients. Each one plays a crucial role in creating that signature rich flavor and moist texture.
Cocoa powder is the star of the show. I recommend using high-quality Dutch-processed cocoa for a deeper, smoother chocolate flavor. If you only have natural cocoa powder, it will work, but the cake may be slightly more acidic.
Buttermilk adds a subtle tang and helps tenderize the cake. If you don’t have buttermilk on hand, you can make a quick substitute by mixing regular milk with a splash of vinegar or lemon juice.
Butter and oil work together to create the perfect texture. Butter gives the cake its rich flavor, while a touch of oil keeps it extra moist.
Brown sugar and granulated sugar combine to add depth and sweetness. The molasses in brown sugar enhances the fudgy quality of the cake.
You'll also need a mixing bowl, whisk, and an electric mixer for the frosting to ensure a smooth, creamy consistency.
How To Make This Midnight Fudge Cake

Baking this Midnight Fudge Cake is easier than you think, and the results are nothing short of spectacular. Let’s go step by step.
Start by preheating your oven to 350°F (175°C) and greasing a 9-inch round cake pan. Dust it lightly with cocoa powder instead of flour—this prevents any white residue on your finished cake.
In a large mixing bowl, whisk together the cocoa powder, flour, baking soda, and salt. This ensures even distribution of the dry ingredients, which is key for a perfect cake texture.
Next, cream the butter, oil, and sugars together until light and fluffy. This step helps incorporate air, making the cake soft and tender. Then, beat in the eggs one at a time, followed by the vanilla extract.
Gradually add the dry ingredients to the wet mixture, alternating with buttermilk. Be careful not to overmix—just stir until everything is combined. Overmixing can lead to a dense cake.
Pour the batter into your prepared cake pan and bake for 30-35 minutes. The cake is done when a toothpick inserted in the center comes out with just a few moist crumbs.
While the cake cools, prepare the fudge frosting by melting butter and stirring in cocoa powder. Slowly mix in powdered sugar and a splash of milk until you reach a smooth, spreadable consistency.
Once the cake is completely cool, generously spread the frosting over the top, letting it cascade down the sides for a luscious, bakery-style finish.
Storage Options
This Midnight Fudge Cake stays fresh and moist for days—if it lasts that long! To keep it at its best, store it in an airtight container at room temperature for up to 3 days.
If you want to extend its life, refrigerate the cake for up to 5 days. Just be sure to let it come to room temperature before serving, as the cold can make the frosting firm.
For longer storage, you can freeze the unfrosted cake for up to 3 months. Wrap it tightly in plastic wrap and foil before freezing. When ready to enjoy, thaw it overnight in the fridge and frost as usual.
Variations and Substitutions
One of the best things about this Midnight Fudge Cake is how versatile it is. Here are some ways to customize it:
Love dark chocolate? Swap some of the cocoa powder for melted dark chocolate in the batter for an even richer taste.
Need a dairy-free version? Use coconut oil instead of butter and swap the buttermilk for almond or oat milk with a teaspoon of vinegar.
Want a mocha twist? Add a teaspoon of espresso powder to enhance the chocolate flavor and give the cake a slight coffee kick.
If you're feeling extra indulgent, fold in some chocolate chips or chopped nuts for added texture and surprise bursts of flavor.
No matter how you customize it, this cake is guaranteed to be a crowd-pleaser. So go ahead—grab your mixing bowl and treat yourself to a slice of chocolate heaven!
