Paleo Banana Bread Mug Cake
I am so excited to share this recipe. I am a massive fan of banana bread and don’t want to brag, but think I have mastered the art of making the perfect loaf.

In my opinion the key is not overcooking the bread so that is remains super moist, and adding lots of banana so that it’s bursting with flavour.

While I try to always have a loaf of my banana bread in the freezer for a quick breakfast or snack, sometimes I’m just not that organized. So here is my solution, a super fast single serving banana bread recipe that requires just a mug and a microwave, it’s so easy.

One of the keys to making this Paleo Banana Bread Mug Cake really delicious is using a very ripe banana, the more black spots the more flavour the bread will have. Ripe bananas are much easier to digest then firmer green or yellow ones and also increase in antioxidant levels as they ripen. Depending on how sweet the banana you are using is, you can skip the honey in this recipe to cut down on the total amount of sugar.

I think this Paleo Mug Cake would be a big hit with kids as it’s exciting to watch the bread rise and cook so quickly in the microwave in just a few short minutes. I added walnuts to the bread for a bit of crunch, but you could substitute them for chocolate chips or raisins for added texture.
