Ahh Chunky Monkey, that delicious flavour combo of bananas, nuts, and a little chocolate! Obviously Chunky Monkey is delicious as an ice cream flavour, but I also created a pretty amazing Chunky Monkey Smoothie, and of course this Chunky Monkey Baked Oatmeal. I love having an easy warm breakfast option that I can pop in the oven while I’m getting my kids up and ready for the day. Baked oatmeals are one of those go-to recipes I come back to again and again because it’s easy to make, my kids love it, and is a nourishing option to start the day.

Add the banana to a small baking dish and mash well with a fork. Add the egg and whisk until fully combined with the banana.

Bake at 375 degrees F for 35 minutes, until set in the centre and lightly golden on top.

Let cool slightly before serving.
