2. Prepare the Mug:

Tips for Success
- Adjust Peppermint Flavor: Start with 1/2 teaspoon of peppermint extract and increase if you prefer a stronger flavor.
- Microwave Time: Cooking times may vary depending on your microwave. Start with 60 seconds and add 10–15 seconds as needed.
- Grease the Mug: To prevent sticking, lightly grease the mug with cooking spray or a small amount of butter.
