FAQs
Can I use baking soda instead of baking powder?
Baking powder is preferred here for proper rising. If using baking soda, pair it with a small splash of vinegar or lemon juice to activate it.
How ripe should the banana be?
Very ripe bananas (with lots of brown spots) work best for sweetness and texture.
Can I make this without nuts?
Yes, you can leave out the nuts or replace them with chocolate chips or dried fruit.
Is this mug cake vegan?
It can be! Use plant-based milk and oil instead of butter.
Can I use self-rising flour?
Yes, if using self-rising flour, omit the baking powder and salt.
Why did my mug cake overflow?
Make sure to use a mug that holds at least 12 oz to prevent overflow while microwaving.
Can I double the recipe?
For best results, make one mug cake at a time. Doubling may lead to uneven cooking in the microwave.
Can I add protein powder?
Yes, replace a tablespoon of flour with a scoop of your favorite protein powder, but the texture may change slightly.
What toppings go well with this?
Whipped cream, a drizzle of nut butter, a sprinkle of cinnamon, or even ice cream are great toppings.
Can I use a banana-flavored extract?
Yes, but it’s not necessary if you’re using a ripe banana.
