- 2 tablespoons milk (any type works)
- 1 teaspoon pure vanilla extract
- 1/4 cup (50g) granulated sugar

Time-Saving Tips for Busy Bakers
Pre-measure your dry ingredients and store them in small jars or bags for a quick grab-and-go option. Use a microwave-safe mug with a handle for easy mixing and cooking. If you’re making multiple cakes, prep the batter in a bowl first, then divide it into mugs for even cooking.
Storage and Reheating Made Simple
Mug cakes are best enjoyed fresh, but if you have leftovers, cover them with plastic wrap and store at room temperature for up to a day. To reheat, microwave for 10-15 seconds to restore that just-baked warmth. Avoid overcooking to keep it moist!
Common Questions Answered
Can I use a different type of flour? Yes, but make sure to adjust for self-rising flour by adding baking powder. What if I don’t have a microwave? Bake in a preheated oven at 350°F (175°C) for 10-12 minutes. Why is my cake dry? Overcooking is the culprit—stick to the recommended time and check for doneness!
