Banana baked oatmeal tastes like banana bread but in oatmeal form! Made with simple ingredients and in one bowl, it is a delicious and healthy baked oatmeal perfect for a healthy breakfast, a snack, dessert, or meal prep.
Preheat the oven to 350 degrees Fahrenheit. Grease a 9x9-inch baking dish.
Mash bananas. In a medium-large bowl, add your bananas and mash with a fork until mostly no lumps remain.
Mix ingredients. To your bowl, add the wet ingredients of eggs, honey, vanilla bean paste, and milk, and mix well to combine. Add your dry ingredients of oats, cinnamon, nutmeg, baking powder, and salt, and mix well to combine. Stir in chopped walnuts.
Bake. Pour the oat mixture into the greased pan. Sprinkle with chocolate chips (if using). Bake for 25-30 minutes until golden brown on top and firm. Let cool for 5 minutes and slice into 9 equal-sized bars.
