This is a great cake, and I need to make it more often. The catch is, it's made in three shallow 8-inch round pans. I have an old set from Wilton. They are about 1 ½ inches deep and work perfectly. But these days 8x2 inch cake pans seem to be more popular, and I still haven't tested it in that particular depth of pan. I have made it as two 9-inch round layers, and while it was good, it wasn't as impressive as it is made with 3 layers!

I'll update the photos one of these days, but for now here are some notes on the cake recipe. It's a very rich and moist one, if you can't tell by the ratios.
Dutch Process Cocoa Powder
The key is to use Dutch process cocoa. I got a good deal on Rodelle Dutch at one point and used some of that, but I think it would also be good with Hershey's Dark. The frosting, however, is best with natural style cocoa. I've tried it with Dutch and never liked the flavor as much as when made with natural cocoa powder.
Let me know what you think! And I hope you like the photo. If you're wondering who that little beaver is, it's Buc-ee. He's the mascot for a popular chain of roadside stores here in Texas. He obviously approves of this cake.
Update: I made the "three layer" chocolate cake" again using two 9 inch pans. The cake did not rise very much and since I used wider pans, it wasn't as tall. We love the flavor of this devil's food cake, but it you want a taller cake, you might want to consider a different Chocolate Cake. The one one the link is also excellent and more statuesque. This one is still VERY good -- just not super tall when made as 2 9-inch layers. It's better made as a three layer cake made in 8 inch pans.
Recipe

Three Layer Chocolate Cake With Frosting
Ingredients
Cake
- 1 ¼ cups water
- 4 ounces unsweetened chocolate chopped -- any brand is fine (114 grams)
- ¼ cup Dutch process cocoa powder (20 grams)
- 1 teaspoon instant coffee or espresso powder
- 1 teaspoon vanilla extract
- ¾ cup all-purpose flour (110 grams)
- ¾ cup cake flour (84 grams)
- 1 teaspoon baking soda
- ½ teaspoon kosher salt
- 8 ounces unsalted butter at room temperature (230 grams)
- 1 ½ cups packed dark brown sugar (336 grams)
- 3 large eggs at room temperature and lightly beaten in a separate bowl
- ½ cup sour cream at room temperature (114 grams)
Favorite Chocolate Frosting
- 8 tablespoons of unsalted butter softened (114 grams)
- 3 cups sifted confectioners' sugar sift or aerate before using (350 grams))
- ¾ cup natural style cocoa powder
- 1 ½ tablespoons of sour cream room temperature
- 1 pinch of salt
- 1 teaspoon vanilla extract
- 4 to 6 tablespoons of heavy cream plus more as needed or use a combination of cream and whole milk
Instructions
- Preheat oven to 350 degrees F. Grease and flour 3 8-inch round pans or use 2 8x2 inch pans.
- In a saucepan, bring the water to a boil. Turn off heat and stir in chocolate, cocoa powder and instant coffee. Stir until chocolate is melted and mixture is smooth. Stir in vanilla. Set aside to cool for about 10 minutes.
- Meanwhile, sift together both flours, baking soda and salt.
- In the bowl of a stand mixer fitted with a paddle, beat the butter until creamy. Add the sugar and beat on medium high for about 3 minutes, scraping sides of bowl often. Reduce mixer speed to medium low and add the eggs slowly - a few tablespoons at a time. Beat just until incorporated, then beat in the sour cream.
- With mixer still on low, add the flour mixture and the chocolate mixture alternately, ending with the flour. Scrape sides of the bowl again and mix well but do not overbeat. Divide batter among the three pans and bake for about 23 minutes or until cakes spring back when touched. You may need to shuffle the cakes around in the oven halfway through so they'll bake evenly.
- Let cool for 10 minutes on a wire rack, then invert and let cool completely before frosting.
- Frosting: To make the frosting, beat the butter until creamy. Gradually add the sugar and beat until well mixed, then add the cocoa powder and beat until mixed - it should look crumbly and pasty. Add the sour cream and salt and beat well, then gradually add the cream, scraping sides of the bowl, until frosting starts looking smooth and creamy. Taste and adjust sugar and cream as needed.

This looks like my perfect recipe (coffee, cocoa+chocolate, oil, butter). Curious where the recipe comes from...or is it a CM original? Happy New Year, Anna!

My go to is Chocolate Butter Cake. It's my favorite, along with anyone I serve it! I'm anxious to try this in comparison.
Anna says
I guess the best way I can describe it is a bit more fine crumbed, right crumbled and delicate than Black Magic. Hope that helps!

Hmm I'm intrigued because the black magic cake is also my go-to. Can you give some more detail about how the taste/texture of this one differs and in your opinion is superior? I may just give this a go.

You would think that after all the sugar I have eaten the last month, that looking at sweets would be sickening, but I can't wait to make this!!! It looks and sounds amazing.
Cheryl says
As soon as I saw sour cream I knew it would be a great recipe!

I've had two slices of this cake and it is wonderful!
