These soft, chewy "Chunky Monkey" banana baked oatmeal cups are naturally sweetened with ripe bananas and honey, and packed with oats, dark chocolate chips, and crunchy walnuts. A cozy, make-ahead breakfast that’s easy to prep and perfect for busy mornings—no blender needed!
Preheat the oven to 400°F. Grease a 12 cup muffin tin, or line with silicone liner.
In a large mixing bowl, whisk together the mashed banana, milk, eggs, oil and honey until fully combined.
1 cup mashed bananas, ⅔ cup milk, 2 large eggs, 2 tbsp oil, ¼ cup runny honey
Add all remaining ingredients and stir until well combined.
2 cups oats, 1 tbsp brown sugar, 1 tsp ground cinnamon, 1 pinch ground nutmeg, ¼ tsp salt, ⅓ cup dark chocolate chips, ⅓ cup chopped walnuts
Divide mixture between muffin cups, gently shake them to level out. Either cover and refrigerate overnight or bake right away for 15-20 minutes or until the top is lightly golden brown.

Notes
Egg replacements: 2 tbsp ground flax + 5 tbsp water (let sit for 5 minutes before adding), or ½ cup extra mashed banana (your muffins will be softer, but still delicious)
Oats: I recommend quick oats if you want to skip the overnight soak - you’ll need a couple tablespoons extra because they soak up less liquid. Regular rolled oats work best with an overnight soak. Steel cut oats or instant oats do not work.
Honey: A mild, runny honey works best here. You can also use maple syrup instead.
