🥘 Ingredients
Boxed Cake Mix- Use a box of your favorite boxed cake mix, and you'll always love the results. I like to use devil's food cake, red velvet, and yellow cake mixes because I keep them on hand and they're great on their own or with add-ins. I do not recommend an angel food cake mix.
Water- To hydrate the mix, you will need some regular tap water.

🔪 Instructions
Check out how to make Cake Mix Mug Cakes with these simple step-by-step instructions:
Open a box of your favorite cake mix (any flavor).
Add the measured cake mix to a microwave safe mug and place the remaining mix in an airtight container and store it for future use.
Add your water to the mug with the cake mix.
Mix together with a fork, just until no dry mix remains. Do not overmix.
If desired, add in chocolate chips or sprinkles.
Microwave for 1 minute. The top will appear a little wet in the center but the edges should look set.
Allow the cake to rest for 1-2 minutes to finish cooking and cooling.
Serve warm and enjoy!
📖 Variations
You can use any flavor of cake mix desired including (but not limited to) Chocolate, yellow, white, red velvet, spice cake, lemon cake, strawberry cake, etc. The only cake mix I do not recommend using is Angel food cake as it will not turn out as well as other cake varieties.
🍴 Recipe Tips
You can halve this recipe!
By using ¼ cup of cake mix and 2 tablespoons of water you can have a smaller portion of cake. Note that you'll only need to microwave it for about 30 seconds due to the smaller quantity.
The top center of the cake will appear a little wet, and this is okay. As the cake cools, the small wet spot will evaporate.
🥣 Recipe Add-Ins
If desired, you can add in 1-2 tablespoons of chocolate chips, sprinkles, shredded coconut, carrots, or even zucchini.
Topping the mug cake with anything is optional, but I usually keep it simple with a little whipped cream or powdered sugar.
💭 FAQs
Different microwaves and mug sizes can play an important role in getting the cakes just right. Overcooking the cakes is usually the main culprit as they don't take very long to cook at all.
Yes. Using any liquid with the cake mix can add more flavor in every bite. Adding coffee can make chocolate cake mix taste richer and give a nice mocha flavor.
If you overmix your mug cake ingredients you will get a rubbery cake. The same can happen if they're overcooked too.
