Banana Baked Oatmeal Recipe
Introduction
Banana baked oatmeal is a comforting and nutritious breakfast that blends creamy oats with natural sweetness from ripe bananas. It’s easy to prepare, perfect for busy mornings, and easily customizable with your favorite toppings.

Ingredients
- 1 and 1/3 cups (320g/ml) milk (dairy or nondairy)
- 2 large eggs
- 1/3 cup (80g/ml) pure maple syrup
- 1/4 cup (4 Tbsp; 56g) unsalted butter, melted and slightly cooled
- 1 cup (230g) mashed banana (about 2 large ripe bananas)
- 1 teaspoon pure vanilla extract
- 3 cups (255g) old-fashioned whole rolled oats
- 1 teaspoon baking powder
- 1 teaspoon ground cinnamon
- 1/4 teaspoon salt
- optional: 3/4 cup (90g) chopped walnuts
- optional for topping: melted peanut butter, maple syrup, bananas, berries
Instructions
- Step 1: Adjust your oven rack to the lower third position and preheat the oven to 350°F (177°C). Lightly spray a 9×9-inch square pan or an 11×7-inch rectangle pan with nonstick spray. Choose a pan that holds about 3 quarts; an 8×8-inch pan will be too small.
- Step 2: In a large bowl, whisk together the milk, eggs, maple syrup, melted butter, mashed banana, and vanilla extract until smooth and combined.
- Step 3: Add the oats, baking powder, cinnamon, and salt to the wet mixture and whisk until well incorporated. Fold in the chopped walnuts if using, then pour the batter into the prepared baking pan.
- Step 4: Bake for 30–35 minutes, until the center is nearly set but still slightly soft for creamy baked oatmeal. For a firmer texture, bake until the center is fully set.
- Step 5: Allow to cool for 5 minutes before slicing and serving. Top with optional ingredients like melted peanut butter, extra maple syrup, fresh bananas, or berries as desired.
Tips & Variations
- Swap walnuts for pecans, almonds, or dried fruit to customize texture and flavor.
- Use ripe bananas with brown spots for the best natural sweetness and moisture.
- Substitute maple syrup with honey or agave nectar if preferred.
- For a dairy-free version, use almond, soy, or oat milk and coconut oil in place of butter.
- Try adding a handful of chocolate chips or shredded coconut for extra indulgence.
Storage
Store leftover baked oatmeal tightly covered in the refrigerator for up to one week. Reheat portions in the microwave for about 30–60 seconds or until warm. You can also freeze individual servings in airtight containers and thaw overnight in the fridge before reheating.

FAQs
Can I use quick oats instead of rolled oats?
Quick oats can be used in a pinch, but rolled oats provide a better texture and structure for baked oatmeal. Quick oats may result in a softer, less firm dish.
Can I make this recipe vegan?
Yes, to make it vegan, substitute eggs with flax or chia egg replacers, use plant-based milk, and replace butter with coconut oil or vegan margarine.

Ingredients
Wet Ingredients
- 1 and 1/3 cups (320ml) milk (dairy or nondairy)
- 2 large eggs
- 1/3 cup (80ml) pure maple syrup
- 1/4 cup (4 Tbsp; 56g) unsalted butter, melted and slightly cooled
- 1 cup (230g) mashed banana (about 2 large ripe bananas)
- 1 teaspoon pure vanilla extract
Dry Ingredients
- 3 cups (255g) old-fashioned whole rolled oats
- 1 teaspoon baking powder
- 1 teaspoon ground cinnamon
- 1/4 teaspoon salt
Optional
- 3/4 cup (90g) chopped walnuts
- Optional toppings: melted peanut butter, maple syrup, bananas, berries
Instructions
- Prepare your oven and pan: Adjust the oven rack to the lower third position and preheat the oven to 350°F (177°C). Spray a 9×9-inch square pan or an 11×7-inch rectangle pan with nonstick spray. The pan should hold about 3 quarts; avoid using smaller pans like 8×8-inch as they will be too small.
- Mix wet ingredients: In a large bowl, whisk together the milk, eggs, maple syrup, melted butter, mashed banana, and vanilla extract until fully combined and smooth.
- Add dry ingredients: To the wet mixture, add the rolled oats, baking powder, ground cinnamon, and salt. Whisk to combine everything thoroughly. Then gently fold in the chopped walnuts if using.
- Pour and bake: Pour the oatmeal mixture into the prepared baking pan, spreading it evenly. Bake in the oven for 30–35 minutes, or until the center is almost set for a soft and tender texture. If you prefer a drier and firmer baked oatmeal, bake a few minutes longer until the center is fully set.
- Cool and serve: Let the baked oatmeal cool in the pan for about 5 minutes before serving. Slice or scoop portions and serve with optional toppings like melted peanut butter, extra maple syrup, banana slices, or fresh berries.
- Storage: Cover any leftovers tightly and refrigerate for up to one week. Reheat gently before serving.
Notes
- You can use any milk (dairy or nondairy) according to your preference or dietary needs.
- For a nut-free version, omit the walnuts.
- If using a 9×13-inch pan, baking time may vary slightly; watch the center closely to avoid overbaking.
- This baked oatmeal can be served warm or at room temperature and makes great meal prep for busy mornings.
- Adjust sweetness by varying the amount of maple syrup or using ripe bananas for natural sweetness.
