Step-by-Step Cooking Instructions

Pre-Cooking Prep

Preheat your oven to 350°F. Lightly grease an 8×8-inch baking dish. Mash bananas in a large bowl until smooth.

Cooking Method

1. Whisk mashed bananas, eggs, milk, melted butter or oil, maple syrup (if using), and vanilla extract until combined.

2. Stir in rolled oats, baking powder, cinnamon, and salt.

3. Pour mixture into the prepared baking dish and spread evenly.

4. Let sit for 5 minutes so the oats absorb the liquid.

5. Bake uncovered for 35–40 minutes, until set and lightly golden on top.

Doneness or Texture Check

The center should be set and no longer jiggly. A knife inserted in the middle should come out mostly clean.

Resting or Final Touches

Let baked oatmeal cool for 5–10 minutes before slicing. This helps it firm up and makes serving easier.
