Preheat the oven to 350°F (175°C).

In a blender, pulse the oats until they reach a flour-like consistency. Add all remaining ingredients, except the chocolate chips and a few banana slices reserved for topping, and blend until smooth.

Remove the blender jar from the base and fold in most of the chocolate chips using a spoon, saving some for topping.

Pour the batter into a greased baking tray. Top with the reserved chocolate chips and banana slices.

Bake for 30-35 minutes, or until a knife inserted into the center comes out clean.

Let cool before slicing into the number of slices listed in the recipe details.

Meal Prep Tip: Store extra slices in an airtight container in the fridge for up to 5 days, or freeze individually for up to 3 months. Reheat in the microwave or oven as needed.
