Types of Cocoa Powder
Unsweetened cocoa powder, specifically Hershey’s brand, was used in this cake recipe as it is the most widely available. You can also use higher-quality cocoa powders such as Ghirardelli or those from specialty chocolatier shops, but they can be expensive. It is recommended to avoid using inexpensive store brands as they tend not to produce the best results.
Dutch-process cocoa powder is a type of cocoa that has been treated with an alkali to neutralize its acidity. It has a milder flavor and darker color than natural cocoa powder, and is also easier to dissolve in liquids. When using Dutch-process cocoa powder in place of unsweetened cocoa powder in a recipe, it’s crucial to consider how this lower-acidity powder might slightly alter the overall taste.
*For the dark-colored frosting shown in these photos, Hershey’s Special Dark Unsweetened Cocoa Powder, also known as Dutch-processed, was used. This specific version enhances the deep color and adds complexity to the flavor of your cake and its frosting counterpart.

Why Vegetable Oil?
One of the most frequently asked questions regarding this recipe concerns why vegetable oil is used instead of butter. While substitution *is* technically possible, it significantly impacts texture; you will get a drier result with less cocoa flavor than achieved by using vegetable oil.
