Egg Free Chocolate Mug Cake Ingredients
*Ingredient amounts are located in the recipe card at the end of this post.
- Flour: You will need all-purpose flour to make this mug cake.
- Unsweetened Cocoa Powder: This will give the cake it's chocolate flavor. I like to use Ghirardelli brand cocoa powder or Hershey's Special Dark cocoa powder.
- Sugar: Only a little bit of sugar is needed to sweeten this mug cake. Feel free to add or take away a little bit of sugar according to your taste.
- Baking Powder: This will help the mug cake rise and get fluffy
- Salt: A pinch of salt is added to balance out the sweetness in this recipe.
- Vegetable Oil: Any neutral-flavored oil can be used.
- Milk: You'll need a dairy or nondairy milk of your choice for this recipe.
- Peanut Butter or Nutella: These are used to add flavor and moisture to the mug cake. You can use either one, but I prefer peanut butter. You can also use any other spread of your choice!
- Chocolate Chips: Optional, but recommended for a little bit of extra chocolate flavor.

Mug Cake Tips & Tricks
- Make sure you use the correct mug size – this recipe is designed for an 8-ounce coffee mug. If your mug is bigger or smaller, you may need to adjust the cooking time accordingly.
- Be sure to stir up all of the ingredients until they are completely combined and smooth. This will ensure that your cake cooks evenly and has a nice texture.
- It's important to watch the mug cake as it cooks in the microwave – some microwave wattage is different and they can cook faster than others. Keep an eye on it and stop cooking when the cake is done, but still moist.
- If you want to make sure your mug cake is cooked all the way through, insert a toothpick or a knife into the center of the cake. If it comes out clean, then your mug cake is done!
- Make sure you are using a microwave-safe mug that can withstand heat.
- If you’re using a ramekin instead of a mug, reduce the cooking time to 40-45 seconds. The cake will cook faster due to more surface area being exposed to heat.
