Tips From Our Recipe Developer

Using a wider and shorter cup for this works best and makes it easier to scoop out your cake.
You can substitute all-purpose flour for self-rising flour. Add a ¼ teaspoon of baking powder.
Keep a close eye on the cake while it’s in the microwave and cook it until the center is just set. Depending on your microwave’s wattage, cooking times may vary.
You can substitute mini chocolate chips for regular chocolate chips.
Double the recipe to share this rich cake with a friend. Microwave cakes one at a time if you are making more than one.

Storage Tips

To Store: The cake is a single serving and does not reheat well.

Frequently Asked Questions

What size mug should I use for my Chocolate Mug Cake?

I suggest using at least a 12-ounce mug for this recipe as the batter will rise quite a bit in the microwave.
Using a wide, short cup will make it easier to scoop out your cake. When choosing a mug, make sure that it is microwave safe.
This recipe isn’t designed for a travel mug that may have a stainless steel exterior.

Can I store my Mug Cake to eat later?

I do not recommend storing this mug cake, especially since this recipe only makes enough for one person. Also, the oils tend to separate if you leave this cake out too long, which is normal but doesn’t look appetizing.
However, if you need to store it, place it in the refrigerator, covered, for up to 24 hours.

Can I add mix-ins to my mug cake?

Yes, you can add your favorite mix-ins for extra texture and flavor. While you don’t want to add a lot, you can easily add a few additions.
Some ideas include sprinkles, candy pieces, crushed cookies, mini chocolate chips, white chocolate chips, peanut butter chips, or mint chips, and chopped nuts.

Can I make a dairy-free mug cake?

You can ditch the dairy in this recipe to make a dairy-free mug cake! Use your favorite non-dairy milk, (like almond milk, soy milk, or coconut milk), and use dairy-free chocolate chips.

How can I make a keto chocolate mug cake?

To make a low-carb, keto cake, you will need to replace the all-purpose flour with keto flour (like King Arthur Keto Wheat Flour), a low-carb sugar substitute, replace the milk with water, and use sugar-free chocolate chips.
Quantities and microwave time many differ from this Chocolate Mug Cake recipe.
