Varieties of Cocoa Powder
Unsweetened cocoa powder, particularly Hershey’s model, was used on this cake recipe as it’s the most generally obtainable. You may also use higher-quality cocoa powders akin to Ghirardelli or these from specialty chocolatier retailers, however they are often costly. It’s endorsed to keep away from utilizing cheap retailer manufacturers as they have a tendency to not produce one of the best outcomes.
Dutch-process cocoa powder is a kind of cocoa that has been handled with an alkali to neutralize its acidity. It has a milder taste and darker shade than pure cocoa powder, and can also be simpler to dissolve in liquids. When utilizing dutch-process cocoa powder rather than unsweetened cocoa powder in a recipe, you will need to take into account that it could behave otherwise as a result of its decrease acidity.

Why Vegetable Oil?
One of the regularly requested questions I get is why the cake makes use of vegetable oil as an alternative of butter. Whilst you actually can use butter rather than vegetable oil in the identical quantity, you’ll find yourself with a drier chocolate cake. It has to do with the way in which that the fats clings to the cocoa powder.
In case you don’t need to use vegetable oil, use one other neutral-flavored oil as a replacement fairly than butter. Avocado oil, canola oil, or grapeseed oil are all choices.

Chocolate Ganache: Solely 2 components—chocolate and heavy cream. It’s typically used as icing or as a filling. Some cooks even use it as a dipping sauce paired with fruit like strawberries. You’ll additionally see it on donuts and cupcakes. It’s wealthy, thick, and candy.
Browned Butter Frosting: A bit nuttiness with a toasted caramel-like taste is what makes this frosting a stand-out.
Cream Cheese Frosting: This frosting is creamy, thick, and has a slight tang. Merely add cocoa powder for a chocolate model.
Pistachio Buttercream Frosting: This frosting has a clean, buttery consistency with a slight crunch from the blended pistachio nuts. This frosting pairs so nicely with chocolate cake. Assume Dubai chocolate bar—the mix can’t be beat.
