FAQ

Q: Can I make this mug cake without peanut butter?
A: Yes! You can substitute almond butter, cashew butter, or even leave it out. You might need to add an extra teaspoon of milk to keep it moist.

Q: Can I make this mug cake ahead of time?
A: Mug cakes are best fresh and warm. You can mix the dry ingredients in advance and store in a small jar, then add wet ingredients and microwave when ready.

Q: Can I bake this in the oven instead of the microwave?
A: Absolutely! Pour the batter into a small ramekin and bake at 350°F (175°C) for 12–15 minutes, or until a toothpick comes out clean.

Q: Can I make this vegan or dairy-free?
A: Yes! Use a plant-based milk (like almond or oat) and a vegan butter or nut butter. It works just as well.

Q: How do I know when it’s done?
A: The mug cake should rise and feel set on top but still soft inside. Be careful not to overcook—it can dry out quickly.
