Ingredients You’ll Need
Below is an overview of the ingredients and instructions for making this healthy baked oatmeal recipe. Please be sure to scroll down to the recipe card below for the complete details!
- Eggs – These act as a binder, holding all the ingredients together. We haven’t tested this recipe with egg substitutes like flax eggs or chia eggs but would love to know how it goes if you do.
- Milk – Feel free to use any kind of milk you like best. Dairy milk, almond milk, coconut milk, it all works!
- Butter – This adds a rich flavor. If preferred, light olive oil will also work.
- Vanilla – Don’t skip this! It adds a delicious vanilla flavor and enhances the rest of the ingredients.
- Oats – Use old-fashioned rolled oats, not steel-cut oats or quick oats. Or, the taste and texture won’t be the same! If needed, use certified gluten-free oats.
- Sweetener – We monk fruit sweetener, but coconut sugar or granulated sugar will also work.
- Baking Powder – This helps the oats rise, creating a soft texture.
- Cinnamon – Adds extra depth and subtle warmth.
- Salt – Just a pinch enhances the rest of the ingredients. It doesn’t make the oats salty, but you’ll notice if you’re not there!
- Mixed Berries – Use your favorite frozen berries. We prefer mixed berries, but any combination of blueberries, blackberries, raspberries, and strawberries will work.
How to Make This Easy Berry Oatmeal Bake
- Prepare. Before you begin, preheat your oven to 350 degrees Fahrenheit. Then, grease a 9×13 baking dish, and set it aside.
- Combine the wet ingredients. In a large bowl, whisk the eggs, milk, melted butter, and vanilla until smooth.
- Add the dry ingredients. Stir in the oats, sweetener, baking powder, cinnamon, and salt until well combined.
- Add the berries. Pour the oat mixture into the prepared baking dish. Sprinkle the berries evenly on top.
- Bake. Transfer the dish to the oven, and bake until the center is set and the edges are lightly browned.
Flavor Variations and Add-Ins
Feel free to mix and match different ingredients to make this berry baked oatmeal your own. For instance, you can:
- Swap the berries with peaches, apples, or bananas.
- Add chopped nuts.
- Sprinkle chocolate chips over the oats before baking.
- Add to or swap the cinnamon with nutmeg or allspice.
- Swap or add to the vanilla with almond extract.
- Add chia seeds or flaxseeds (You’ll likely need to add extra liquid if you do.)

Common Questions
Baked oatmeal can be gummy if that batter is left to sit before baking or if too much liquid is used. You want enough to combine and coat the ingredients, but the oats shouldn’t be soggy.
Yes! Combine the ingredients as usual. Then, portion the batter in a greased muffin tin, and sprinkle the berries on top. Bake as usual, adjusting the cooking time as needed until the oatmeal is set.
Absolutely! Follow the recipe as normal, and adjust the baking time as needed.
