Tips
Microwave wattage varies widely; start at 60 seconds and add 15-second increments if needed. Overcooking dries out the cake.
Use a mug with at least 2-cup capacity to prevent overflow as batter rises. Ceramic mugs heat more evenly than glass.
Good to Know
Best served immediately. Leftovers can be covered and refrigerated for 1 day but texture deteriorates.
Dry ingredients can be mixed in the mug up to 8 hours ahead. Add wet ingredients and microwave just before serving.
Serve warm in the mug, optionally with whipped cream, ice cream, or a dusting of cocoa powder on top.
Common Mistakes

FAQ
Can I make this without chocolate chips?
Yes. Omit them entirely or substitute with chopped nuts, sprinkles, or peanut butter chips. The cake will still bake properly.
Why is my cake dense or rubbery?
Microwave time was too long or microwave wattage too high. Start at 60 seconds. The cake should look slightly moist on top when done.
Can I freeze this?
Not recommended. The texture becomes too dry when thawed. Make fresh as needed since it takes only 6 minutes total.
