These muffins are only 200 calories each–which is great considering most muffins on average are around 500+ calories each! I will tell you that they are very dense and not as fluffy as most.
Preheat the over to 400 degrees. Line a 12-muffin ray with paper liners.
In a stand mixer, combine the all-purpose flour, wheat flour, rolled oats, ground cinnamon, baking powder, baking soda, salt, and mashed banana and blend on low speed for 2 minutes. Add the walnuts, brown sugar, vegetable oil, eggs, and reduced-fat buttermilk and blend for 2 minutes on medium speed. Add the vanilla extract and mix until well combined.
Using an ice cream scoop, portion the batter evenly into the muffin tin and top each muffin with 4-5 chocolate chips.
Bake at 400 degrees for 15 minutes. Once they are baked through, remove them from the oven and let cool.
Notes
Try different types of chocolate to make these your own. You could also use chopped walnuts instead (calories will need to be adjusted).
