Tips, Variations & Storage

- Extra decadent: Add a spoonful of Nutella or peanut butter in the center before microwaving.

Cooking Tips
- Microwave power varies: If your microwave is very powerful, start with 50 seconds. Lower wattage may need up to 90 seconds.
- Don’t overcook: The brownie continues cooking slightly after you remove it. It’s better to slightly undercook for a fudgy texture.

Notes
Microwave Power: Cooking time varies by microwave wattage. High-power microwaves may only need 50-60 seconds, while lower-wattage models may require up to 90 seconds. Start with less time and add 10-second intervals as needed.
Texture Tip: Slight undercooking yields a fudgier brownie. The center continues cooking after removal, so it’s better to err on the side of underdone rather than overdone.
Mug Size: Use at least a 12 oz mug to prevent overflow as the batter rises during cooking.
Substitutions: For gluten-free, use 1-to-1 gluten-free flour blend. For dairy-free, use plant-based milk and dairy-free chocolate chips. For lower fat, replace half the oil with unsweetened applesauce.
Storage: Best enjoyed fresh and warm. Can be refrigerated covered for up to 2 days. Reheat for 15-20 seconds in microwave.
