Why Does This Recipe Work?
- Cocoa powder gives a robust chocolate foundation without wateriness.
- Chocolate chips provide extra moisture and bursts of flavor.
- Baking powder yields a true cake texture, as opposed to rubbery results from baking soda or over-mixing.
- Milk and oil keep the cake tender and prevent drying in the microwave.
- Direct mixing in the mug minimizes cleanup and delivers a perfectly-portioned dessert.
Microwave Cake Science
Microwaves cook food by exciting water molecules, heating rapidly from the inside out. This means batters with liquid ingredients and fats cook evenly, rising quickly with the help of baking powder. Mug cakes usually finish in just over a minute, so avoid overcooking for the best texture. Letting the cake rest for a brief minute post-microwave lets steam dissipate and ensures a moist crumb.
Frequently Asked Questions (FAQs)
Q: Can I use self-rising flour?
A: Yes! If using self-rising flour, omit the baking powder and salt.
Q: Why is my mug cake rubbery?
A: Overmixing or overcooking can lead to chewiness. Mix just until combined, and monitor microwaving closely.
Q: Can I make this vegan?
A: Yes. Use non-dairy milk and substitute oil for butter if preferred.
Q: What if I don’t have chocolate chips?
A: The cake is still delicious without them, but you can use chopped chocolate, candy pieces, or leave out entirely.
Q: Can I double the recipe?
A: For best results, make one mug per serving. Doubling in a single mug may result in uneven cooking.
