The Ingredients That Make It Worth It
This Fudgy Chocolate Cake is made with everyday staples, but these four are the ones that truly transform it from simple chocolate cake to the best fudgy chocolate cake you will ever slice into.
- Unsweetened Cocoa Powder: Delivers that deep, rich chocolate flavour and gives the cake its dark, intense character.
- Vegetable Oil: Keeps the crumb soft, moist, and perfectly fudgy without making the cake feel heavy.
- Instant Coffee + Boiling Water: Blooming the cocoa with hot liquid intensifies the chocolate flavour so every bite tastes fuller and richer.
- Heavy Cream + Dark Chocolate (For The Ganache): Melted together, they create a smooth, glossy finish that seals in moisture and adds that luxurious final layer of chocolate.
Note: Please see recipe card at the bottom for a full list of ingredients with measurements.
Make It Your Own
Want to tweak this Fudgy Chocolate Cake a little? Here are some easy add ins and substitutions that work beautifully without messing with that rich, fudgy texture.
- Swap The Milk: Use buttermilk for a slightly tangier, softer crumb, or full cream coconut milk for a subtle coconut note that pairs surprisingly well with chocolate.
- Add Chocolate Chunks: Stir in a handful of chopped dark chocolate or chocolate chips for little pockets of melted chocolate throughout the cake.
- Espresso Boost: Replace the instant coffee with a shot of freshly brewed espresso for a deeper, more intense chocolate flavour.
- Orange Twist: Add finely grated orange zest to the batter for a chocolate orange version that feels a little fancy but takes no extra effort.
- Nutty Crunch: Fold in toasted hazelnuts or walnuts for texture. They add contrast to the soft crumb and make each slice more interesting.
- Liqueur Upgrade: Add a tablespoon of coffee liqueur or hazelnut liqueur to the ganache for a grown up finish.
How To Make Fudgy Chocolate Cake
- Prep Pan: Preheat oven to 350°F (175°C). Lightly grease an 8 inch or 9 inch round cake pan with non stick spray and line the base with parchment paper for easy release.
- Mix The Dry Ingredients: In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, and salt until evenly combined and lump free.
- Add The Wet Ingredients: Add the oil, egg, vanilla, and milk to the dry mixture. Beat for about 30 seconds until smooth and well incorporated.
- Bloom And Combine: Pour in the boiling water mixed with coffee and stir until batter turns smooth and glossy. The batter will be thin, and that is exactly what you need.
- Bake To Perfection: Pour batter into prepared pan and bake for 40 to 45 minutes, or until a toothpick inserted comes out with a few moist crumbs but no runny batter.
- Cool Completely: Let the chocolate cake cool in the pan for 20 minutes, then transfer to a wire rack and cool fully before adding the ganache.
- Make Ganache: Heat cream in a saucepan over low until hot. Remove from heat, add chocolate chips, cover, and sit for 5 minutes before stirring until smooth.
- Chill And Spread: Refrigerate the ganache for about 1 to 1½ hours until thick and spreadable, then evenly frost your Fudgy Chocolate Cake and serve.
Serve this Fudgy Chocolate Cake after a comforting dinner like Slow Cooker Beef Stew With Sweet Potatoes or Creamy Tuscan Chicken. Both are rich, cosy mains that make this chocolate cake feel like the grand finale to a proper sit down meal.
If you are hosting and want a lighter lead in, pair it with Greek Salad. The fresh, bright flavours balance the deep chocolate beautifully, so when dessert hits the table, that first bite of fudgy chocolate cake tastes even more indulgent.
Tips For The Best Fudgy Chocolate Cake
- Do Not Overmix The Batter: Once you add the wet ingredients, mix just until combined. Overmixing can make the cake dense instead of soft and fudgy.
- Use Hot Coffee, Not Just Warm: Properly hot liquid blooms the cocoa and deepens the chocolate flavour. It is one of the secrets to making this the best fudgy chocolate cake.
- Do Not Overbake: Pull the cake out when a toothpick comes out with a few moist crumbs. A completely clean toothpick usually means it has gone too far.
- Let The Ganache Thicken Naturally: Give it time in the fridge to reach a spreadable consistency. Rushing it can make it too runny and slide off your chocolate cake.
Recipe FAQ’s
That thin batter is exactly what you want. The hot coffee and liquid ratio create the signature moist, fudgy texture. Do not add extra flour to thicken it.
Yes, but baking time will change. A 9 inch pan will bake slightly faster than an 8 inch. If using two thinner layers, start checking around the 25 to 30 minute mark.
If it is too runny, let it chill longer. If it becomes too thick, gently warm it for a few seconds and stir until smooth again.

CHOCOLATE CAKE:
- Combine flour, sugar, cocoa powder, baking powder and salt in a large bowl. Whisk thoroughly to combine well.
- Add oil, egg, vanilla and milk to the flour mixture and beat well to combine, about 30 seconds. Pour in the boiling water (with the coffee), and mix until glossy. (Cake batter is thin in consistency.)
- Pour the cake batter into the prepared pan. Bake for about 40-45 minutes, or until a toothpick inserted in the centre of the chocolate cake comes out semi-clean with small amount of cake (not runny batter) on it due to the fudgy texture.
- Remove from oven and allow to cool for 20 minutes. Transfer cake from the pan to a wire rack and cool completely before frosting.
CHOCOLATE GANACHE:
- Pour the cream into a small saucepan and heat over low heat for a few minutes. Watch that it doesn’t boil or simmer it. Once the cream is hot, turn stove off and take the saucepan off the heat.
- Add in the chocolate chips; cover saucepan with a lid and let sit for a good 5 minutes to soften and melt the chocolate.
- Uncover, and stir slowly first, with a spatula or wooden spoon, gradually mixing faster until ganache is smooth, creamy and glossy. Refrigerate for one hour or hour and a half until thick enough to spread (similar consistency to Nutella).
- Spread evenly over the cake.

I just made this cake two days ago. It’s literally the perfect fudgy chocolate cake I’ve been looking to make. The ganache was super easy to do also. I made it for a celebration that was cancelled due to a blizzard. I expect we’ll be enjoying it for several more days. It’s absolutely delicious!
Karina,
can this cake be cut in half horizontally and made into a two layer? It appears high enough but thought you would have a better thought on this. I tried to find comments on this but so many to read through. I didn’t find anything in first several pages.
Hi Den, I wouldn’t advise it, this cake is supposed to be super fudgy and moist rather than a sturdy sponge. But I do have a recipe that might suite try my Matilda’s Chocolate Cake.
Delicious, but fair warning, my chocolate ganache turned into fudge when i left it in the fridge overnight in its own bowl, make sure you put it on the cake before.
Works out perfectly EVERYTIME!!!
Best recipe ever💕🙌
