Step-by-step instructions
- Preheat your oven to 350°F (175°C) and grease a 9×9-inch baking dish.
- In one bowl, mix together the rolled oats, baking powder, cinnamon, salt, and brown sugar.
- In another bowl, whisk together the mashed bananas, milk, egg, melted butter, and vanilla extract until smooth.
- Pour the banana mixture into the bowl with the dry ingredients. Stir until everything is well combined. If you’re using walnuts, fold them in gently.
- Transfer the mixture to the greased baking dish and spread it out evenly.
- Bake for 35-40 minutes, or until the top is golden and a toothpick inserted into the center comes out clean.
- Let the bake cool slightly before serving. Enjoy it warm for a comforting breakfast any day of the week.
Best ways to enjoy it
This Banana Cinnamon Oat Breakfast Bake is delightful on its own, but you can elevate it even further. Consider serving it warm with a dollop of Greek yogurt or a drizzle of honey. Fresh fruit, like berries or sliced strawberries, adds a refreshing contrast to the warm bake. For a decadent treat, serve with a scoop of vanilla ice cream or a sprinkle of maple syrup on top!
Storage and reheating tips
To keep your Banana Cinnamon Oat Breakfast Bake fresh, store it in an airtight container in the refrigerator for up to five days. For longer storage, consider freezing individual portions wrapped in plastic wrap and then placed in a freezer-safe bag. This way, you can enjoy it anytime! To reheat, simply pop a piece in the microwave for 30-60 seconds or warm it in the oven at 350°F for about 10 minutes.
Helpful cooking tips
- Make sure your bananas are ripe for the best sweetness; the more speckled they are, the better!
- Don’t skip the resting time after baking; this allows the flavors to meld together beautifully.
- If you’re short on time, you can prepare the mixture the night before, cover it, and let it sit in the fridge overnight before baking in the morning.
Creative twists
There are endless ways to customize your Banana Cinnamon Oat Breakfast Bake. Feel free to add in some chocolate chips for an indulgent treat, or use almond milk instead of regular milk for a dairy-free option.
