The Best Chocolate Cake Recipe
This chocolate cake truly is the best chocolate cake! It’s incredibly moist thanks to a combination of buttermilk, oil, water (or coffee – you pick), eggs, and high fat cocoa powder. It’s also incredibly flavorful thanks to the dark chocolate we’re using (read more about the cocoa below).
For this recipe, I’m using half of my normal chocolate cake recipe. We’ll fill one 8-inch pan with batter, bake, top with ganache, and THAT’S IT! No layers. No decorating. And no waiting around for the cake to cool completely. You can serve this one warm with a slather of chocolate ganache and fresh berries.
How to Make Chocolate Ganache
If you’re new to baking, a ganache is made by heating whipping cream and then pouring it over chocolate and stirring until the chips are melted and you’ve created a silky smooth chocolate ganache.
To make chocolate ganache, you can heat the cream in the microwave (in a microwave safe bowl), or over the stove in a double boiler. I like to keep it simple and just use my microwave.
Frequently Asked Questions
While this cake is SUPER SIMPLE to make, there are a few questions I want to answer to make sure it’s truly as easy as possibly for you.
What Type of Chocolate Should Be Used in Chocolate Ganache Cake?
When it comes to chocolate and baking, I think it’s incredibly important to use good quality chocolate. Chocolate is a flavor that we want to stand out and make an impact. Regular store brand or no-brand chocolates really won’t cut it if you want the best chocolate cake.
What are we looking for? For this chocolate cake and the chocolate ganache, we want to use DARK chocolate. Don’t let that scare you off if you’re not typically a dark chocolate fan. When we use dark chocolate in baking, we’re adding other ingredients that tone down the bitter flavor of dark chocolate, while also allowing the chocolate flavor to stand out. If you start with a milk chocolate or regular cocoa powder, you’ll lose so much of the chocolate flavor once you add the other ingredients.
When choosing your chocolate, you also want to look for the fat content. Higher fat chocolate (higher fat anything, actually) helps create and retain moisture in our cakes.
Brands of Chocolate I Recommend
- Cocoa Powder: Callebaut Extra Brute Cocoa Powder
- Dark Chocolate Chips: Callebaut Bittersweet Chocolate Chips
- Semi-Sweet Chocolate Chips: Callebaut Semi-Sweet Chocolate Chips
I also think Guittard and Valrhona make excellent dark chocolate.
Can I substitute the dark chocolate for regular chocolate?
I would highly advise against it. As I mentioned above, you’ll lose a lot of the chocolate flavor. Try the dark chocolate first, and then if it’s just too strong for you, compare it to a regular cocoa.
Can I double the recipe?
Absolutely! If you do, you’ll want to bake the cake in two 8-inch pans for about 20 to 25 minutes.
Can I bake this recipe in a square pan?
For sure! If you use an 8″ x 8″ square baking pan, use the same bake time as recommended below. If you use a 9″ x 9″ square baking pan, reduce the bake time by 5-ish minutes.
Remember: your cake is done when you insert a toothpick in the center and it comes out with a few moist crumbs on it.
