How to Make It
One chocolate chip mug cake, step by step.
- 01
Choose the mug
Use a microwave-safe mug with enough room for the cake to rise slightly without overflowing.
- 02
Mix the dry ingredients
Add the flour, sugar, baking powder, and salt to the mug. Stir until evenly combined.
- 03
Add the wet ingredients
Pour in the milk, melted butter, and vanilla extract. Stir gently until the batter is smooth and no dry pockets remain.
- 04
Fold in the chocolate chips
Stir most of the chocolate chips into the batter, keeping a few aside to scatter over the top.
- 05
Microwave the cake
Microwave on high for about 60–90 seconds, depending on your microwave. The top should look set while the center stays soft and tender.
- 06
Let it rest
Let the mug cake sit for 1–2 minutes before eating. The cake will continue to set slightly while the chocolate stays warm and melty.
SVI SWEET Tip
Save a few chocolate chips for the top.
Adding a few chocolate chips after mixing makes the finished mug cake look better and gives you extra pockets of melted chocolate right on the surface.
Substitutions
Make it work with what you have.
Chocolate chips
Use milk, dark, or semi-sweet chocolate chips. Chopped chocolate also works well and creates larger melted pockets.
Butter
A neutral-flavored oil can replace the melted butter in the same quantity, although butter gives the cake a richer flavor.
Milk
Regular dairy milk or an unsweetened plant-based milk can be used in the same amount.
Vanilla
Vanilla extract gives the classic flavor, but a tiny amount of almond extract can be added for a slightly different bakery-style taste.
Storage
Best while the chocolate is melty.
Fresh is best
This mug cake is best enjoyed shortly after cooking while the cake is warm and the chocolate chips are still soft and melted.
Short-term storage
If needed, cover the cooled mug cake and keep it at room temperature for a few hours.
Reheating
Microwave for about 5–8 seconds to warm the cake and soften the chocolate again. Avoid overheating.
FAQ
A few helpful answers.
Why did my chocolate chip mug cake turn dry?
It was probably microwaved too long. Start with the shorter cooking time and add only a few extra seconds if the center still looks very wet.
Can I use chopped chocolate instead of chocolate chips?
Yes. Chopped chocolate works especially well and creates larger pockets of melted chocolate throughout the cake.
Why did my chocolate chips sink?
Some sinking is normal in a soft mug cake batter. Keeping a few chips aside and adding them to the top helps distribute the chocolate more evenly.
Can I double this recipe?
For the most even cooking, make two separate mug cakes instead of doubling the batter in one mug.
