If you tried my 4-Ingredient Banana Oatmeal Bars or my 5-Ingredient Healthy Blueberry Oatmeal Cookies, you already know the deliciousness we’re about to dive into.

These silly simple blueberry oatmeal breakfast bars are only made with 4 simple ingredients: overripe bananas, creamy almond butter, oats, and fresh blueberries. 

They’re soft and chewy with rich flavor and in spite of only being sweetened with ripe mashed bananas, they taste nice and sweet.

If you’re looking for more of a crumb bar texture, try my Blueberry Oatmeal Crumb Bars which feature a blueberry filling, crumble topping, and shortbread crust.

The best part about these blueberry oat bars is all of the simple ingredients can be found at any grocery store and no fancy equipment like a stand mixer or food processor or baking experience is needed. Plus, there is no all purpose flour, butter, eggs, or refined sugar in this great recipe!

Each of the four ingredients wears many hats in the sense that they provide multiple functions and qualities to the recipe.

Let’s discuss the simple ingredients to make this magic happen.

Ingredients For Healthy Blueberry Breakfast Bars:

Ripe Bananas: Large ripe bananas are all we use to sweeten these incredible blueberry bars. For this reason, be sure to use bananas that have plenty of brown spots to ensure you’re getting a lot of sweetness and moisture content.

Unsweetened Almond Butter: Creamy almond butter plays a critical role because it sets up to become a chewy bar, eradicating the need for butter, flour and eggs thusly.

You can use any thick and sticky well-stirred nut butter or seed butter here, such as peanut butter, sunflower seed butter, or cashew butter. 

I love the creamy nutty flavor of almond butter in these bars and I find almond butter and blueberries pair very nicely.

Rolled Oats: Some old fashioned oats gets mixed in to add texture, whole grains, complex carbohydrates and deliciousness to the bars.

You can also use quick oats or instant oats instead of rolled oats.

If you need the recipe to be gluten-free, be sure the package of oats specifies that they are certified gluten-free. I use sprouted gluten-free oats. For a grain-free option, use almond flour instead of oats.

Fresh Blueberries: Juicy blueberries bring little pops of tangy sweet flavor to the breakfast bars to make them that much more enticing. You can swap them out with chopped strawberries, raspberries, or apples if you’d like.

Sea Salt: A pinch of sea salt goes a long way in bringing out all of the delicious flavors, making the bars taste sweeter and richer.

You can add any of the following goodies to customize these healthy breakfast bars

Optional Additions:

• 2 to 4 Tbsp pure maple syrup, white sugar, brown sugar, or coconut sugar for sweeter bars.
• 1 ½ tsp ground cinnamon for warm and fuzzy feelings.
• 1 tsp pure vanilla extract for delicious vanilla notes.
• 1 large egg for fluffier bars.
• ½ to ⅔ cup chopped walnuts or pecans, sunflower seeds, or pumpkin seeds for nutty seedy bars.
• 2 to 4 tablespoons of your favorite protein powder. If you add more than 4 tablespoons of protein powder, you will also want to add some form of liquid like oil or milk to get the consistency right.
• 1 tablespoon of ground flax seeds or chia seeds. If you add more than one tablespoon, you will also want to add some water since these seeds are both very absorbent.
• Add grated lemon zest and a little lemon juice for some citrus flavor.

Now that we’ve covered the simple ingredients for these delicious healthy snack bars, let’s bake them!

How to Make Healthy Blueberry Breakfast Bars: 

Preheat the oven to 350 degrees Fahrenheit and line a 9” x 9” baking pan with parchment paper. You can also use an 8” x 8” square pan but you will need to bake the bars slightly longer.

Mash the bananas in a large bowl until they are creamy.

Mix in the almond butter until the wet ingredients are well combined. If you’re adding vanilla extract, do so now.

Add the rolled oats, ground cinnamon and sea salt (the dry ingredients) to the bowl with the wet ingredients and mix well until a thick, sticky dough forms. 

Gently fold in the blueberries.

Transfer the blueberry mixture to the prepared baking dish and spread it into an even layer. If desired, press extra blueberries into the top of the bars.

Bake on the center rack of the preheated oven for 20 to 25 minutes, or until the bars are slightly golden brown around the edges and feel firm when gently poked.

Allow the bars to cool to room temperature before slicing and serving.

Store blueberry breakfast bars in an airtight container in the refrigerator for up to 7 days. You can freeze these bars in a freezer bag for up to three months.

Enjoy these delicious breakfast bars cold or warm with a little melted butter (or vegan butter) on top. No one’s judging!

They are also great with a scoop of vanilla ice cream for a decadent dessert or some Greek yogurt and fresh berries or other fresh fruit for a more substantial breakfast.

The next time you’re craving a sweet treat or want to meal prep a grab-and-go breakfast or snack, these blueberry breakfast bars are here for you.

Ideal for busy weekdays when you want to have snacks on hand to tide you over between meals or school lunches for kids, these delicious bars are portable and perfect for life on the go.
