4. Tools You Need
You likely already have everything required:
- Microwave-safe mug (12 oz or more)
- Tablespoon and teaspoon for measuring

- ¼ tsp baking powder
- Pinch of salt
- 3 tbsp milk
- ½ tbsp melted butter (or neutral oil)

🔸 Instructions
Step 1: Combine Dry Ingredients
In a microwave-safe mug, mix the flour, sugar, baking powder, and salt using a fork.
Step 2: Add Wet Ingredients
Stir in the milk, melted butter or oil, and vanilla extract. Mix until smooth. Avoid overmixing—some lumps are okay.
Step 3: Customize (Optional)
Add mix-ins like chocolate chips, berries, or a dollop of Nutella in the center.

6. Key Tips for Mug Cake Success
- Microwave Timing Matters: Every microwave is different. A 1000-watt microwave might take 60 seconds; a 700-watt might take 80–90 seconds.
- Avoid Overmixing: It leads to a dense, chewy texture.
- Don’t Overfill the Mug: Leave at least 1 inch of space at the top.
- Use a Wide Mug: Allows better heat distribution.
- Mix the Ingredients Well: But don’t worry about small lumps—they’ll settle during cooking.

| Variation | What to Add |

These customizations add flavor and make the dessert feel new every time.
