Prep Your Dish: Preheat your oven to 180°C (350°F). Lightly grease your baking dish or line it with parchment paper to prevent sticking.
Mash the Bananas: In a large mixing bowl, mash the bananas until smooth and creamy. The riper the bananas, the sweeter and more aromatic your baked oats will be.
Build the Batter: Add the oats, milk, egg, honey, vanilla, cinnamon, baking powder, and salt. Whisk until everything looks well combined and slightly thickened. Fold in any optional mix-ins like nuts, chocolate, or chia.
Pour & Smooth: Transfer the mixture into your baking dish. Use a spatula to smooth the top so it bakes evenly.
Bake Until Set: Bake for 28–32 minutes, or until the top is golden, the edges are firm, and the center feels set. Let cool for at least 5 minutes; flavors deepen as it rests.
Serve Warm & Enjoy: Slice into squares or spoon it out like warm cake. Pair it with soothing drinks like Honey Lemon Tea or vibrant morning drinks like the Spiced Pear Smoothie for a complete, nourishing breakfast.
