A quick single-serving microwave mug cake made with boxed cake mix, milk, and oil. Ready in about 2 minutes with endless flavor options and minimal cleanup.
Microwave times vary by power: 700–900W start at 90 seconds; 1000–1100W start at 70–80 seconds; 1200W+ start at 60–70 seconds. Do not overcook or the cake will become rubbery. Use at least a 12-ounce mug and limit mix-ins to 1–2 tablespoons to prevent overflow. For dairy-free or gluten-free, use suitable milk and cake mix. Water can replace milk, but add an extra 1/2 teaspoon oil for moisture.
