How to Make a Mug Cake

You'll find a detailed ingredient list and step-by-step instructions in the recipe below, but let's go over the basics:

Mug Cake Ingredients

You likely already have all the ingredients for this chocolate mug cake recipe on hand. Here’s what you’ll need: 

  • Flour: This easy chocolate mug cake recipe starts with all-purpose flour. 
  • Sugar: Sugar sweetens things up and balances the bitter cocoa powder. 
  • Cocoa powder: Two tablespoons of unsweetened cocoa powder ensures a rich chocolate cake. 
  • Baking soda: Baking soda acts as a leavening agent, which means it helps the mug cake rise. 
  • Salt: A pinch of salt enhances the overall flavor of the mug cake, but it won’t make it taste salty. 
  • Milk: Milk keeps the cake batter from drying out during the microwaving process. 
  • Oil: A neutral oil, such as canola oil, keeps the batter moist without adding flavor. 
  • Water: A tablespoon of water helps create the perfect texture. 
  • Vanilla: A dash of vanilla extract is the perfect finishing touch.
