What is baked oatmeal?Baked oatmeal is a method of cooking oatmeal where you combine rolled or quick oats with eggs and milk to create a muffin or cake-like breakfast bake.
The texture is like a hearty bread or muffin and it’s delicious topped with peanut butter, honey, and fresh berries.
Featured Ingredients
- Quick-cooking oats oats & oat flour: this streusel topping is held together with a base of both quick-cooking oats and oat flour.
- Light brown sugar: brown sugar adds a delicious touch of sweetness to this streusel topping.
- Unsalted butter: make sure your butter is not only unsalted but cold! You’ll press the butter into the rest of the streusel topping ingredients until it creates a crumble.
- Vanilla extract: feel free to sub for almond extract for an alternate flavor. Delish!
- Banana: we love using mashed banana in our baked oatmeal to add both moisture and flavor.
- Eggs: we have not tested this baked oatmeal with a flax egg.
- Honey & vanilla extract: all you need is a touch of sweetness from honey and vanilla extract for this blueberry muffin baked oatmeal. The natural sweetness from both the blueberries and the banana add so much!
- Unsweetened oat milk: feel free to sub for any dairy free milk if you prefer.
- Quick-cooking oats & oat flour: can’t have baked oatmeal without oats! We’re using a combination of quick cooking oats and oat flour. Use certified GF oats to keep this recipe gluten free.
- Blueberries: you’ll need about 2 cups of blueberries for this baked oatmeal. We recommend using fresh for optimal flavor, but frozen will also work.

Add rolled oats, flour, baking powder, salt, and blueberries and mix until everything is thoroughly combined.
