Ingredients
I made this cake for my best friend’s birthday, and let me tell you, it stole the show!
Everyone raved about how delicious it was and pretty much begged me for the recipe.
Luckily for you, it couldn’t be easier to recreate. Here’s what you’ll need:
- All-Purpose Flour + Cornstarch: For structure and to ensure the best texture in the sponge.
- Unsweetened Cocoa Powder: Adds rich, deep chocolate flavor to the cake and frosting.
- Baking Powder and Baking Soda: The leavening agents that help the cake rise and become light and fluffy.
- Salt: Enhances the chocolate flavor and balances the sweetness.
- Granulated Sugar and Light Brown Sugar: A combination of sugars for sweetness and moisture.
- Vegetable Oil: Keeps the cake moist and tender.
- Large Eggs + Yolks: Bind the ingredients and contribute to the cake’s structure.
- Buttermilk + Sour Cream: Adds tanginess and helps create a soft, tender crumb.
- Hot Coffee: Intensifies the chocolate flavor without making the cake taste like coffee.
- Vanilla Extract: Enhances the overall flavor of the cake and frosting.
- Fudge Frosting: A thick and decadent blend of chocolate, cream, butter, salt, and powdered sugar.
How to Make Chocolate Fudge Cake
I have many amazing chocolate cake recipes, but the real star of this show is the fudge frosting.
And guess what? It’s the easiest part of the whole recipe!
Here’s how it’s done:
1. PREP: Preheat the oven to 350°F, grease and line three 8-inch cake pans.
2. MIX: Whisk the flour, cocoa, cornstarch, leavening agents, and salt in a bowl. Blend the buttermilk and sour cream in a separate container.
3. BLEND: Whisk the sugars and oil in a large bowl until smooth. Add the eggs and yolks, then incorporate the buttermilk mixture.
4. COMBINE: Alternate adding the dry ingredients and hot coffee, beginning and ending with dry, mixing gently.
5. BAKE: Divide the batter between the pans, bake for 30-35 minutes, and cool in the pans for 10-15 minutes before transferring to a wire rack.
6. FROSTING: Melt chocolate with cream using a double boiler, then mix in the butter, salt, and powdered sugar until smooth. Set aside to thicken.
7. ASSEMBLE: Layer the cakes with frosting, then cover the top and sides. If you have any frosting left, pipe the excess on top.
8. CHILL: Refrigerate the cake for 30-60 minutes to set, then serve and enjoy!
Tips For the Best Chocolate Fudge Cake
While there are a few steps to this, I promise it’s easier than it looks. And the taste? It’ll make you swoon!
But before you begin, check out these tips:
- Use room temperature ingredients. They blend more easily, so the batter won’t overmix.
- Sift the dry ingredients. It ensures the leavening agents are evenly distributed and lightens the sponge.
- Hot coffee magic. Don’t skip the hot coffee! It enhances the chocolate flavor like you won’t believe – and no, it doesn’t make the cake taste like coffee.
- Make it two layers. I think the three layers are pretty impressive, but it’ll be just as showstopping if you bake it in two 9-inch cake pans.
- Tap out air bubbles. Before baking, gently tap the filled cake pans on the counter to release any trapped air bubbles.
- Toothpick test. Insert a toothpick into the center of the cakes to check for doneness. If it comes out clean or with just a few moist crumbs, the cakes are ready.
- Cool before frosting. Allow the cakes to cool completely before frosting to avoid a melty mess.
- Crumb coat first. Apply a thin layer of frosting as a crumb coat, chill the cake, then add the final layer of frosting for a neater appearance.
- Chill for clean slices. Refrigerate the cake for about 60 minutes before slicing. Then, run a chef’s knife under hot water, wipe it dry with paper towels and slice. Repeat for each cut.
Recipe Variations
This chocolate cake is pretty perfect as it is. But that doesn’t mean you can’t jazz it up!
Here are a few ways I like to make this extra special:
- Add crispy pearls or Oreo chunks between the layers for a bit of crunch
- Make half the amount of frosting for the coating and fill it with something different, such as peanut butter, coffee, caramel, or raspberry frosting.
- Add swirls of salted caramel whipped cream or raspberry whipped cream on top to lighten it up.
- Add fruit to the middle layers, such as chopped cherries
How to Store
As devilishly addictive as this cake is, it’s very rich. So, you might have leftovers.
If that’s the case, here’s how to store them:
To Store: Cover the cake in a cake dome or transfer leftovers to an airtight container. Store in the fridge for up to 5 days.
To Freeze: Securely wrap the chocolate fudge cake (or slices) in plastic wrap and aluminum foil and place it in an airtight container or freezer bag. Freeze the cake for up to 3 months.
Thaw frozen cake in the fridge overnight. For the best texture and flavor, allow chilled cake to come to room temperature for about 30 minutes before serving.
