What is Chocolate Chip Mug Cake?
Mug cakes are quick-mix cakes which are prepared and cooked in a mug. These microwave mug cakes usually take less than 5 minutes to make and are the perfect easy snack.
Ingredients in Chocolate Chip Mug Cake
You'll only need a few simple ingredients to make this delicious cake in a cup.
- Brown sugar: makes your mug cake moist and fluffy. You can substitute with white sugar if needed.
- Canola oil: or use any other flavourless vegetable oil. I don't recommend olive oil as it has a strong taste. You can also substitute for melted butter or margarine.
- Milk: I use full fat dairy milk, but you can also use skim milk or any plant-based alternative like soy, almond, oat etc. You can also use water if necessary.
- Vanilla: use vanilla extract or essence. Gives the cake a rich flavour.
- Flour: use plain or all-purpose flour. Can substitute 1:1 with gluten-free flour to make a gluten-free mug cake.
- Baking powder: NOT baking soda. Make sure it is within its best before date. Measure accurately as using too much baking powder will make your cake bitter.
- Chocolate chips: I used dark (semi-sweet) chocolate chips. You can also use milk or white - the choice is yours!

Frequently Asked Questions
How do I make gluten-free mug cake?
Simply replace the flour with gluten-free flour. Also check that your baking powder and chocolate chips are both gluten-free.
Can you make mug cake in a bowl?
Yes, microwave mug cake can be made in a bowl. Just mix your ingredients in a microwave-safe bowl (try to get a smaller bowl so the batter isn't spread too thinly). Depending on the size of the bowl, it may cook quicker or slower, so microwave for 30 seconds then check, and continue to microwave in 10 second bursts until cooked through.
Cooking mug cake in the oven
You can also bake your mug cake in the oven. Transfer the batter to an oven-safe ramekin or mug and bake at 160°C (320°F) for 10-15 minutes. You'll know it's ready when the top is set and springs back lightly.
Can I bake my mug cake in the air fryer?
Yes, transfer the batter to an oven-safe ramekin or mug and bake at 160°C (320°F) for approximately 5 minutes. You'll know it's ready when the top is set and springs back lightly.
Troubleshooting Chocolate Chip MUg Cake
Why did my chocolate chip mug cake overflow?
If your cake overflowed then you are using a mug which is too small. Use a mug which is at least 350 mL (12.5 oz) or use a small microwave-safe bowl. If your cake starts to overflow, stop the microwave and let the cake sink down then resume cooking.
Why is my mug cake hard and rubbery?
It is likely that you have overcooked the cake. 1 minute will be plenty of cooking time for this cake in the majority of microwaves. If you know that your microwave is more powerful than normal microwaves, reduce the power to 80%. When in doubt, a slightly undercooked cake is far better than an overcooked cake!
Why does my mug cake have lumps of flour?
If you find lumps of flour in your cooked mug cake, it means you need to stir the ingredients together more until well combined. You can try using a fork to combine the batter well. Make sure to scrape down the edges of the mug when you are stirring.
Serving suggestions
Mug cake is delicious by itself! You can also try:
- Serve with a dollop of whipped cream
- Serve with a scoop of ice cream
- Add caramel chips for a caramel mug cake
- Try using a mixture of dark, white and milk chips for a triple chocolate mug cake
- Top with sprinkles
- Add chocolate fudge sauce after cooking

Notes
Measurement
- Please note that my recipes are measured in metric cups and spoons which are larger than US cups and spoons. Most recipes will be fine if measured in US cups and spoons, but please use the weight (grams) measurement for the most accurate result.
Storage
- I recommend eating the mug cake while it is fresh. It isn't designed to keep well.
Substitutions & Tips
- Oil: you can use any type of vegetable oil. I don't recommend using olive oil as it will give the cake an odd flavour. You can also substitute oil with an equal amount of melted butter or margarine.
- Sugar: you can substitute brown sugar with regular white sugar. The brown sugar just keeps it a bit moister.
- Baking powder: you can substitute ½ teaspoon of baking powder with ¼ teaspoon of baking soda. You can also leave it out completely and replace the plain flour with self-raising flour.
