As one of the most popular recipes on my site, this Ultimate Chocolate Fudge Cake needed the option for a 9" version that can feed a large crowd! It's made with my favorite butter-oil combo chocolate cake recipe that stays moist for days without sacrificing a rich, buttery flavor. And as with just about all of my chocolate recipes, it calls for two types of cocoa powder to achieve a deep chocolate flavor that only the combination of dutch process AND black cocoa powder can provide. Finally, these decadent cake layers are assembled with a classic ganache that spreads on creamy and sets up into a truffle-thick consistency.

Ingredients

For the cake layers:

180 g (1 ½ cups) all-purpose flour
63 g (¾ cup) dutch process cocoa powder
31 g (¼ cup + 2tbsp) black cocoa powder
1 ¼ teaspoon baking powder
1 ½ teaspoon kosher salt
297 g (21 tablespoon) unsalted butter, room temp
375 g (1 ⅔ cups + 3 ½ tbsp) granulated sugar
3 eggs, room temp
1 tablespoon vanilla extract
170 g (¾ cup) sour cream, room temp
150 g (¾ cup) extra light tasting olive oil

For the ganache:

510 g (2 ¼ cups) heavy cream
510 g (18 oz) dark chocolate

Instructions

For the cake layers:

Preheat the oven to 325 degrees F and grease & line two 9 inch cake pans with parchment paper.
In a large bowl, whisk together the flour, cocoa powders, baking powder, and salt. Set aside.
In the bowl of a stand mixer fitted with the paddle attachment, cream together the butter and sugar for 2-3 minutes until light & fluffy.
Mixing on low speed, add the eggs one a time. Scrape down the bowl and mix in the vanilla.
Add half of the dry ingredients and mix until just combined.
Mix in the sour cream and oil.
Add the rest of the dry ingredients and mix until just combined. Scrape down the bowl to ensure everything is evenly incorporated.
Divide the batter between the prepared cake pans and smooth out the tops with an offset spatula.
Bake the cakes for about 35-40 minutes or until the edges begin to pull away from the sides of the pan and a toothpick inserted comes out clean.
Turn the cakes out onto a wire rack to cool completely.

For the ganache:

In a small saucepan, heat the heavy cream over low heat and bring to a simmer or about 190 degrees F.
Add the chocolate to the heavy cream, place the lid on top, and allow to sit for a couple minutes.
Remove the lid and gently stir with a rubber spatula until the ganache is smooth. Alternatively, you can use an immersion blender for an extra smooth texture.
Allow the ganache to sit for about 1 hour at room temperature or until thickened to a spreadable consistency.

For assembly:

Place the first cake layer on a cake stand or plate. Use a 3 tablespoon cookie scoop to add 5 scoops of ganache to the first layer. Use an offset spatula to spread into an even layer. Place in the fridge to chill for about 10 minutes.
Place the second cake layer on top upside down. Add a few large dollops of ganache to the top of the cake, and use the offset spatula to smooth out the top, and spread the excess all over the sides. Continue decorating the cake as desired, and enjoy!
