Ingredients
1⅓ cups (320 ml) milk (dairy or nondairy)
2 large eggs*
⅓ cup (80 ml) pure maple syrup*
¼ cup (56 g) unsalted butter, melted and slightly cooled*
1 cup (230 g) mashed banana (about 2 large ripe bananas)
1 teaspoon pure vanilla extract
3 cups (255 g) old‑fashioned rolled oats*
1 teaspoon baking powder
1 teaspoon ground cinnamon
¼ teaspoon salt
Optional: ¾ cup (90 g) chopped walnuts
Optional toppings: melted peanut butter, maple syrup, fresh bananas, berries
Instructions
Preheat oven to 350 °F (177 °C) and position rack in the lower third. Grease a 9×9‑inch square or 11×7‑inch rectangular pan.
In a large bowl, whisk together milk, eggs, maple syrup, melted butter, mashed bananas, and vanilla until smooth.
Add oats, baking powder, cinnamon, and salt; whisk to combine. Fold in walnuts if using.
Pour batter into the prepared pan, smoothing the top.
Bake for 30–35 minutes until the edges are golden and the center is just set (for soft texture). For firmer baked oatmeal, bake an additional 5–10 minutes.
Cool for 5 minutes. Serve warm, sliced or scooped, with your favorite toppings.
Notes
Make-Ahead & Freezing: Bake and cool completely. Refrigerate airtight for up to 1 week. Reheat in the microwave or bake at 350 °F for 10 minutes. For freezing, slice into portions, wrap individually, and freeze for up to 3 months.
Muffin Pan Variation: Grease a 12-cup muffin tin and fill to the top. Bake for 28–30 minutes. Skip liners or spray them well to prevent sticking.
Substitutions:
Eggs: Use ⅓ cup unsweetened applesauce or extra mashed banana.
Butter: Swap with melted coconut oil (best for dairy-free).
Oats: Quick oats can make it too soft; steel-cut oats require soaking and longer baking.
