Black Cocoa Sheet Cake

The fluffiest dark chocolate sheet cake made with black cocoa powder and frosted with a whipped black cocoa frosting.

I have been just a little obsessed with black cocoa lately. I don’t think I’ve even baked with regular cocoa powder since making my OG Black Cocoa Cake.  I now also have BEST Black Cocoa Brownies, a Black Cocoa Frosting that tastes like creamy Oreo deliciousness. 

In case you were wondering what black cocoa powder tastes like, it’s still a cocoa powder so obviously like chocolate but it just has that distinct flavor that you find in Oreos. It’s slightly more bitter and earthy but in a good way? Idk, I love it though. 

How To Make Black Cocoa Sheet Cake, Step-by-Step Photos

Black Cocoa Sheet Cake

  1. Whisk together the flour, cocoa powder, baking powder and salt until they’re evenly distributed.
  2. In a separate bowl, whisk the oil, sugar, eggs and sour cream until they’re well combined and smooth.
  3. Sift the dry ingredients over the wet and whisk just a little – about halfway. 
  4. Pour in the hot coffee and whisk until the batter is completely smooth.
  5. Scrape the edge of the bowl and give it a good mix. Pour the batter into the prepared pan. 
  6. Bake for 30-35ish minutes, until the tallest part of the cake, in the center, springs back when you press on it. If you’re hesitant, give it another few minutes or so.
  7. Let the cake cool completely before frosting. 

Black Cocoa Frosting

  1. Beat the butter with the whisk attachment until it’s pale, fluffy and creamy looking. 
  2. Add the powdered sugar, cocoa powder, salt and vanilla bean paste and turn the mixer to LOW speed just until the sugar is dissolved. Increase the speed to medium-high until the sugar is mixed in well. 
  3. Stream in the heavy whipping cream slowly with the mixer on low speed or in 4-5 increments, stopping to scrape the edge of the bowl each time so it all gets mixed in. Use a rubber spatula to smooth the frosting out a little when it’s done. 
  4. Spread the frosting onto the cooled cake. 

How To Store Black Cocoa Cake

This cake can be stored airtight at room temperature for a couple of days before refrigerating. I recommend placing it in an airtight container and refrigerating it for up to a week after. Freeze if it’s any longer than that. 

To freeze the cake, place it in an airtight container and then place the container in a freezer bag, squeezing out all the excess air. Bring them back to room temperature by thawing at room temperature for a few hours before serving. 

I haven’t looked back since using black cocoa for my cakes and cupcakes and I hope you don’t either!

As always, have a blessed day and happy baking!

  1. This looks wonderful! Could you clarify the amount of butter in the frosting, please? (113 g would be a half cup, one stick — I assume you mean one cup/227 g, but just want to be sure.) Thank you!
