The perfect, healthy and delicious breakfast! These blueberry oatmeal bars are great on the go and freeze very well. They couldn’t be easier with just 8 ingredients (you could even use 6) and 2 minutes of prep time. The oven does the rest of the work for you and leaves you with a gooey, delicious breakfast bar.

Why you’ll love this recipe

There are so many reasons to love these oatmeal breakfast bars. If I were to choose the top 3 reasons you need to try this healthy blueberry recipe, it would be these:

Double duty: oatmeal bars can be versatile – as a breakfast to start the day with, or a dessert to enjoy after dinner. Serve with vanilla icecream for the best post-dinner treat. 

A few simple ingredients: you only need a handful of ingredients to make these baked bars and a bonus is that most of the ingredients are probably already in your cupboard! 

Healthy: making recipes from scratch ensures that you know all of the ingredients that go into your food. Oats are a great source of fibre, as are blueberries. And blueberries are high in vitamin C and K, and are also very low in calories. A win win!

What is an oatmeal bar?

Oatmeal bars are the solution to many breakfast bar ideas that I have. You whip up one tray/baking dish, then once cooled, you can divide into individual portions. This makes it into a ‘bar’. 

This is great for portion control, but is also amazing for storing in the freezer. This makes this blueberry oatmeal bar recipe perfect for meal prep, as you can whip up a batch and freeze half of the servings for a later date (up to 3 months!) 

Ingredients

Ingredients to make oatmeal bars laid out on a pale blue background and labelled.

Oats – rolled oats are the base of these oatmeal bars, which I love as they’re such a cheap and delicious ingredient. It also makes this recipe gluten-free as I don’t use flour. 

Blueberries – you can use frozen or fresh blueberries for this recipe. Bare in mind you get a bit of a purple hue onto the oats when you use frozen (still gorgeous) as the colour bleeds a little. 

Greek yogurt – the best pairing for the best breakfast bars. It provides a nice level of moisture when you eat the bars with a dollop of yogurt, but if you’re on the go you can definitely enjoy them solo!

How to make blueberry oatmeal bars

Preheat the oven to 350°F/180°C

  1. Start by mashing the banana in a large bowl (Image 1).
  2. Then add the wet ingredients (Image 2).

3. Whisk together to combine and ensure everything is incorporated (Image 3).

4. Then add the oats and blue berries and gently mix together (Image 4).

5. Line a rectangular baking tray or dsih with parchment paper, before pouring in the mixture. Spread with the back of your spoon to level the mix. Top with some brown sugar. Pop in the oven for 20-25 minutes, until the oat mix starts to turn golden brown on top (Image 5).

6. Remove from the oven and allow to cool (Image 6).

Once cooled, divide into 6/8 bars and pop in the fridge. Heat for 30 seconds each time you eat breakfast and serve with yogurt and a drizzle of honey. (Can also be eaten cold if you have to eat on route)!

Variations/ Adaptations

Mix up the fruit: try these blueberry oat bars with a different kind of berry. Strawberry, raspberries, blackberries, or even frozen mixed berries for lots of variety. 

The base is neutral making the recipe easily customisable, just be sure to add more honey if you’re using a berry that’s more bitter. 

Add a citrus fruit: you could make this breakfast bar feel even boojier by adding some lemon zest/juice. 

Make it vegan: you could make these vegan by substituting the honey with maple syrup. You then also want to replace the egg with a vegan egg mix, which would be 1 tbsp flaxseed meal, mixed with 2.5 tbsp of water. This ensures that the ingredients still bind together. 

Increase the protein: feel free to up the protein per serve by adding your favourite protein powder. I’d suggest a vanilla flavour for this recipe.

Tips for the best result

  • Line your baking dish with parchment paper to prevent the blueberry bars from sticking to the tray.
  • Adjust the sweetness depending on your preference. I tried to keep this as healthy as possible, so it’s not overly sweet. But if you want that, increase that honey!
  • When freezing, make sure the clingfilm is sealed tightly with a few layers. This will prevent freezer burn.

How To Store/ reheat and freeze

How long do oatmeal bars last in the fridge/freezer?
These blueberry oatmeal bars keep up to a week in the fridge, or 3 months in the freezer. I recommend wrapping them in clingfilm, then in parchment paper to prevent freezer burn. 

It’s a matter of preference but I prefer to freeze them in individual portions, that way I can take just one serving out of the freezer at a time when I fancy it! It also reduces the amount of time it takes to defrost. 

How do you defrost oatmeal bars? The best way that I suggest to defrost is to pop in the fridge to defrost evenly overnight. If you’re in a hurry, you can defrost them in a microwave set to the defrost mode- then once defrosted, you can increase the heat to medium.

FAQs

Can you use frozen blueberries?

Yes you can! Bare in mind you get a bit of a purple hue onto the oats when you use frozen (still gorgeous) as the colour bleeds a little. Some packets of frozen blueberries also say to not re-freeze, so be conscious of this! 

Do you eat blueberry oatmeal bars hot or cold?

The answer is both! If you’re in a hurry, they’re great served cold as you can just grab them out of your handbag and enjoy on the move. If you want to sit down and enjoy a more warming breakfast, enjoy the blueberry breakfast bar hot with a dollop of Greek yogurt. 

Can you use quick cooking oats for this recipe?

I wouldn’t as I think the texture of the bar would be too dense. Rolled oats are also deemed as healthier too so they would be my preference for these oatmeal blueberry bars.
