Banana oatmeal muffins are soft, cozy and hearty, bakery style muffins made with healthy ingredients like bananas and rolled oats. They're topped with a sweet cinnamon oat topping.
Mix the oats, brown sugar and cinnamon togetheruntil well combined. Pour the melted butter into the cinnamon oat mixture, mixing with a fork until the butter is thoroughly mixed through.
In another bowl whisk the bananas until thoroughly mashed. Then whisk in the eggs and sugar until smooth and well combined. Once smooth and well combined, whisk in the oil, maple syrup and vanilla extract until smooth and well combined.
Stir the dry ingredients into the wet 1/3 at a time. Before mixing in the last 1/3 of the dry ingredients, toss the mini chocolate chips (if using) into the dry ingredients. Then mix the remaining dry ingredients, along with the chocolate chips into the wet ingredients. Do not overmix. A few flour streaks is fine.
Scoop the sticky banana and oatmeal muffin batterinto each of the muffin liners, alternating every other cup. Top the muffins with the cinnamon oat topping or more chocolate chips.
Bake the muffins at 375 F (190 C) for 18 - 22 minutes.Cool the oat banana muffins in the muffin pan for 5 - 10 minutes. Carefully remove the muffins to cool to room temperature and enjoy.
