Epic Pitfalls: 5 Mistakes to Avoid With Your Mug Cake

• Old Discard Drama: Using very old sourdough discard (over 24 hours) can make the cake taste too sour or even funky.
• Tiny Mug Disaster: Don’t use a small mug or you’ll be cleaning chocolate eruptions from your microwave. Go big or go home (at least 400ml capacity).
• Over-mixing Mayhem: Stir just until combined or you’ll get a tough, rubbery cake. Not tasty, IMO.
• Microwave Power Varies: Cooking time may need adjusting based on your microwave wattage. Watch closely and check at 90 seconds.
• Hot Stuff Caution: Mug will be super hot. Use an oven mitt and let it cool before devouring, unless you’re into culinary risk.

Alternatives and Variations for Every Craving

• Gluten-Free: Swap all-purpose flour for a gluten-free blend just make sure it’s for cakes, not bread flour.
• Vegan Option: Use plant-based milk and skip the jam or use vegan chocolate for add-ins.
• Mix-In Mania: Sprinkle in nuts, coconut, dried fruit, or candy for personalized flair.
• Mocha Twist: Add ½ tsp instant coffee for a grown-up flavor punch.
• Fruit Forward: Stir in blueberries or raspberries for a juicy surprise.
