Alternative Cooking Methods
🔹 Oven Method: Bake in an oven-safe ramekin at 350°F (175°C) for 10-12 minutes.

Vishal’s Recipe Tips
✅ Use a big mug – The brownie will rise slightly, so use a large microwave-safe mug to avoid overflow.
✅ Don’t overcook – Microwave in short bursts, checking for doneness after 60 seconds. Overcooking can make it dry.
✅ Extra gooey? – Under-microwave slightly for a molten lava texture.
✅ Boost the flavor – Add a pinch of espresso powder to enhance the chocolate!
✅ Make it even richer – Drizzle with melted chocolate, caramel, or peanut butter.
Storage Instructions
Refrigerate: If you have leftovers (unlikely!), cover and store in the fridge for up to 1 day.
Reheat: Microwave for 10-15 seconds to bring back the fudgy texture.
Make ahead: Mix the dry ingredients in advance and store in a small container—just add wet ingredients and microwave when ready!
