Can I make peanut butter banana mug cake without eggs?

Yes! This mug cake is naturally egg-free. The mashed banana acts as a binding agent and provides moisture, making eggs unnecessary for structure or flavor.

How ripe should bananas be for mug cakes?

The riper, the better. Overripe bananas with lots of brown spots are ideal—they’re sweeter, mash easily, and give your mug cake the perfect texture and natural sugar.

Is it safe to microwave a mug cake with peanut butter?

Absolutely. Peanut butter melts beautifully in the microwave and helps keep the cake moist. Just make sure to use a microwave-safe mug and watch the cook time to avoid overcooking.

Can I substitute almond butter or Nutella in this mug cake recipe?

Yes! Almond butter, cashew butter, sunflower seed butter, or even Nutella can be swapped in 1:1 for peanut butter. Each variation brings its own twist to the flavor—so go with what you love!
