Recipe Tips

✅ Use a standard microwave-safe mug – A 10-12 oz mug works best to prevent overflow.
✅ Don’t overcook – The cake continues to cook slightly after microwaving, so check for doneness at 60 seconds and add 5-10 seconds if needed.
✅ Add extra moisture – For a richer texture, stir in 1 teaspoon of milk or melted butter before microwaving.
✅ Customize it! – Try mixing in white chocolate chips, a drop of vanilla extract, or topping with whipped cream and sprinkles.
