Invite your kids to help make this chocolate sheet cake
Dutch-processed cocoa (sometimes called “alkalized” or “European- style” cocoa) is the best choice for most baked goods. Using a natural (or “unalkalized”) cocoa powder results in a drier cake. (File Photo: Steven Labinski/Flickr, CC BY-NC-ND 2.0)
This chocolate sheet cake requires that you use Dutch-processed cocoa powder. What exactly is that?

Dutch-processed cocoa (sometimes called “alkalized” or “European- style” cocoa) is the best choice for most baked goods. Using a natural (or “unalkalized”) cocoa powder results in a drier cake.

Add flour mixture and whisk until smooth, making sure to scrape corners of saucepan.
