• Chopped walnuts or pecans (optional): these add crunch and healthy fats look for nuts that are crisp and smell nutty
• Unsalted butter or coconut oil: helps keep the bake moist plus adds richness

Instructions

Prepare the Baking Dish:

Preheat your oven to 375 degrees Fahrenheit or 190 degrees Celsius. Lightly grease a nine-by-nine inch baking dish with butter or nonstick spray so nothing sticks.

Mix the Dry Ingredients:

In a large bowl mix together oats nuts if you are using cinnamon baking powder and a pinch of salt. Stir well to distribute everything evenly and break up any clumps for uniform texture.

Mix the Wet Ingredients:

In a separate bowl whisk together milk eggs maple syrup melted butter or coconut oil and vanilla extract. Whisk longer than you think until fully combined and creamy this helps distribute flavors and avoid streaks of egg.

Layer the Berries First:

Scatter half of your mixed berries across the bottom of your baking dish. Try to get an even spread for bursts of berry flavor in every bite.

Add the Oat Mixture:

Pour the dry oat mixture over the berries. Spread evenly with a spatula or spoon. Pack it down lightly to create a level surface but avoid pressing too hard.

Pour Over the Wet Mixture:

Slowly pour your wet mixture over the oats making sure every part gets soaked. Tap the dish gently on the counter to help liquid settle and fill gaps this is key for a moist bake.

Top with More Berries:

Scatter the remaining berries across the top. This not only looks pretty but gives a second wave of berry flavor.

Bake to Golden Perfection:

Transfer the dish to your preheated oven. Bake for thirty-five to forty minutes until the center is set but still soft and the top is golden and slightly crisp. The aroma will be irresistible.

Cool and Serve:

Remove from oven and let cool for about five minutes. This helps the bake firm up and makes slicing easier. Serve warm with a dollop of yogurt and extra berries if you want a little luxury.

My favorite part is how the cinnamon perfumes the whole kitchen, and our breakfast table chatter always feels a bit more cheerful when this bake is on the menu. The kids love picking their own berry combos and I cherish how it brings us together, even just for a short slow morning.

Storage Tips

Store leftovers covered in the fridge up to four days. Individual slices are quick to reheat in the microwave for busy mornings, or pop the whole dish back in the oven at low heat to gently warm. If you want to freeze, wrap well and thaw in the fridge overnight.

Ingredient Substitutions

Swap nuts for seeds like pumpkin or sunflower if you need nut-free. Any berry mix works, whether fresh or frozen (just scatter them directly from the freezer without thawing). You can replace butter with coconut oil and use plant-based milk and maple syrup to keep things dairy-free.

Serving Suggestions

Serve warm out of the oven with a dollop of Greek yogurt or a splash of extra maple syrup. Add some fresh berries on top for color and bite. A drizzle of almond butter or a sprinkle of extra cinnamon makes it even more decadent.
