A cross between a British flapjack and baked oatmeal, these blueberry baked oatmeal bars are perfect for quick and easy on-the-go breakfasts or healthy snacks.

I shared a similar recipe several years ago, but wanted to share an updated version that is easier, tastier, and more nutritionally balanced. Not only am I a better nutritionist, but I’m a better baker, and I want my recipes to reflect this.
These blueberry baked oatmeal bars are hearty, crumbly, and absolutely delicious. They are full of fruit and fiber, and kid-approved, making them something the whole family can enjoy. Plus, they freeze very well, so you can make a double or triple batch and store leftovers for busy days and weeks to come.

Why You’ll Love Them
- Source of Fiber – The combination of rolled oats and blueberries gives each bar over 3 grams of fiber.
- Handheld – These bars work well as a healthy grab-and-go breakfast for busy mornings.
- Keep Well – These blueberry baked oatmeal bars keep well in the fridge and freezer, making them a great breakfast meal prep idea.

Ingredients + Substitutions
- Oats – To make the bars and add some complex carbohydrates and fiber. You can use old-fashioned oats or rolled oats; however, instant oats and quick oats are not recommended.
- Blueberries – To add some natural sweetness, fiber, and micronutrients. You can use fresh or frozen blueberries; see the notes section of the recipe card for details.
- Almonds – To add some healthy fats and nutty flavor. The recipe calls for slivered almonds, but any chopped nuts will work.
- Flour – To ensure the bars are hearty and dense. The recipe calls for all-purpose flour, but you can use gluten-free flour if needed. See the notes section of the recipe card for details.
- Brown Sugar – To sweeten the bars and create a moist and chewy texture.
- Honey – To sweeten the bars and add some flavor. Maple syrup will also work well.
- Butter – To add some fats and give the bars good structure.
- Milk – To add a bit of protein and moisture to the bars. I used cow’s milk, but you can use almond milk or another non-dairy milk if preferred.
- Vanilla Extract – To flavor the bars.
- Baking Powder – To add some airiness to the bars.
- Salt – To season.


Dietary Adaptions
To Make them Gluten-Free: Use certified gluten-free oats and swap the all-purpose flour for 1:1 gluten-free flour.
To Make them Dairy-Free: Swap the butter for coconut oil and the milk for almond milk.

Red’s Nutrition Tip
Although I used fresh blueberries in these baked oatmeal bars; you can use frozen berries if desired. In fact, fresh fruit and frozen fruit have very similar nutritional values and, in some cases, frozen fruit retains more vitamin C as it’s harvested at peak ripeness and flash-frozen, which helps preserve nutrient content.
Serving Suggestions
These blueberry baked oatmeal bars are a good source of carbohydrates, fat, and fiber. They work well as a healthy snack; however, if you want to enjoy them as a balanced meal, I’d suggest serving them with a source of protein, such as:
- Greek yogurt
- Skyr
- Cottage cheese
- Hard-boiled eggs
- Almond butter
- Peanut butter

Storage
To Refrigerate: Once cooled and sliced, the bars can be stored in an airtight container in the fridge for up to 5 days.
To Freeze: Once cooled, wrap the bars individually and store them in an airtight container in the freezer for up to 3 months.
