Ingredients

2 ripe bananas, mashed
1 ½ cups rolled oats
1 teaspoon baking powder
½ teaspoon cinnamon
¼ teaspoon salt
1 cup milk (dairy or non-dairy)
1 egg (or flax egg for a vegan option)
1 teaspoon vanilla extract
1 cup mixed berries (fresh or frozen)
¼ cup chopped nuts or seeds (optional, for crunch)
1 tablespoon maple syrup or honey (optional, for extra sweetness)
1 tablespoon melted butter or coconut oil (for added richness)

Instructions

Preheat & Prep – Preheat your oven to 375°F (190°C). Lightly grease an 8×8-inch baking dish with butter or cooking spray to prevent sticking.
Mix Dry Ingredients – In a large bowl, combine the rolled oats, baking powder, cinnamon, and salt. Stir well to ensure even distribution of the ingredients.
Whisk Wet Ingredients – In a separate bowl, mash the bananas until smooth. Add the milk, egg, vanilla extract, melted butter or coconut oil, and maple syrup (if using). Whisk until well combined.
Combine & Fold in Berries – Pour the wet mixture into the dry ingredients and stir gently until everything is evenly incorporated. Be careful not to overmix. Gently fold in the mixed berries and nuts (if using), ensuring they are evenly distributed.
Bake – Transfer the mixture to the prepared baking dish, spreading it evenly. Bake for 30-35 minutes, or until the top is golden brown and set. You’ll know it’s done when a toothpick inserted in the center comes out clean.
Cool & Serve – Allow the bake to cool for about 5-10 minutes before slicing. This helps it set and makes it easier to serve.
Enjoy! – Serve warm as is, or top with Greek yogurt, a drizzle of honey, extra berries, or a sprinkle of chopped nuts for added texture and flavor.

Storage & Reheating

Refrigerate – Store leftovers in an airtight container in the fridge for up to 5 days.
Reheat – Warm individual servings in the microwave for 30 seconds, or bake at 350°F (175°C) for 10 minutes.
Freeze – Cut into portions and freeze for up to 2 months. Reheat in the oven or microwave when ready to eat.

Topping & Serving Ideas

This Berry Oatmeal Bake is already delicious on its own, but you can elevate it with some extra toppings:

A dollop of Greek yogurt – Adds creaminess and protein.
A drizzle of honey or maple syrup – Enhances the natural sweetness.
A handful of toasted nuts or coconut flakes – Provides crunch and nuttiness.
A sprinkle of chia or flaxseeds – Adds extra fiber and omega-3s.
A scoop of nut butter – Almond or peanut butter makes it extra indulgent.

Customization Tips

Swap the fruit – Try using chopped apples, pears, or peaches instead of berries.
Add chocolate – A handful of dark chocolate chips makes it feel like dessert for breakfast.
Boost the protein – Stir in a scoop of protein powder or collagen peptides for extra nutrition.
Go dairy-free – Use almond, oat, or coconut milk instead of dairy milk.
Make it extra crunchy – Add granola on top before baking for an irresistible texture.

Why This Recipe Works

The combination of rolled oats and bananas creates the perfect balance of chewy and soft textures, while the berries add a pop of juicy tartness. Unlike traditional oatmeal, which can sometimes feel mushy, baking it in the oven brings out a lightly crispy top layer, making it more enjoyable to eat. Plus, since it’s naturally sweetened, you’re nourishing your body without added sugar overload.

Whether you’re grabbing a quick bite on a busy morning or savoring a slow breakfast with a hot cup of coffee, this Berry Oatmeal Bake is a winning choice. It’s wholesome, satisfying, and just the right amount of sweet—no refined sugar needed. Try it once, and it just might become a staple in your morning routine!
