Preheat the oven:
Preheat your oven to 375°F (190°C) and lightly grease an 8x8-inch baking dish.

In a large bowl, combine oats, baking powder, cinnamon, and salt.
Mix wet ingredients:
In another bowl, mash bananas and whisk in eggs, milk, peanut butter, vanilla, and honey (if using).
Combine:
Pour the wet mixture into the dry ingredients and stir until evenly mixed. Add nuts or chocolate chips if desired.
Pour and bake:
Transfer mixture to the prepared baking dish. Smooth the top and add fruit slices or extra toppings.
Bake:
Bake for 30–35 minutes, or until the top is golden and a toothpick comes out clean.
Cool and serve:
Let it cool for 10 minutes, then slice and serve warm with a drizzle of peanut butter or almond milk.
