How long will these chocolate muffins last?

These chocolate muffins with chocolate chips are best stored in an airtight container at room temperature and eaten within five days of baking. For longer-term storage, freeze in an airtight container for up to three months.

Do I have to use Rising Star Baking Supply's cocoa powder?

No, you can use cocoa powder from any brand as long as it's 100% cacao. Dutch-processed cocoa will also work with this recipe!

Did you forget to include vanilla extract?

Nope, I found there wasn't a discernible difference between chocolate muffins made with vanilla extract and those without. So to help you save a few cents, you don't need to use it unless you want to!
