These Blueberry Oatmeal Breakfast Bars are soft, chewy, and packed with juicy blueberries. They make a perfect grab-and-go breakfast or a wholesome snack, combining the natural sweetness of honey or maple syrup with the goodness of oats and whole wheat flour.
Ingredients
(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)
2 cups rolled oats
1 cup whole wheat flour
½ cup honey or maple syrup
1 teaspoon baking powder
½ teaspoon cinnamon
¼ teaspoon salt
1 cup unsweetened applesauce
½ cup milk (dairy or non-dairy)
1 egg
1 teaspoon vanilla extract
1 ½ cups fresh or frozen blueberries
Directions
Preheat the oven to 350°F (175°C) and line an 8x8-inch baking dish with parchment paper.
In a large bowl, mix the oats, flour, baking powder, cinnamon, and salt.
In a separate bowl, whisk together the applesauce, milk, egg, vanilla, and honey (or maple syrup).
Pour the wet ingredients into the dry ingredients and stir until just combined.
Gently fold in the blueberries.
Spread the batter evenly into the prepared baking dish.
Bake for 30-35 minutes or until golden brown and a toothpick inserted in the center comes out clean.
Let the bars cool completely before cutting into squares.

Variations
Nutty Crunch: I sometimes add a handful of chopped walnuts or almonds for extra texture.
Chocolate Twist: A few dark chocolate chips mixed in make these bars feel like a treat.
Banana Substitute: If I don’t have applesauce, mashed banana works just as well.
Coconut Flavor: A sprinkle of shredded coconut on top adds a nice touch.
Different Berries: Raspberries or chopped strawberries are great substitutes for blueberries.
Storage and Reheating
I store these bars in an airtight container at room temperature for up to two days. If I want them to last longer, I keep them in the fridge for up to a week. For longer storage, I freeze them for up to three months and thaw them overnight in the fridge. To warm them up, I microwave for about 10 seconds.
FAQs
How do I keep the bars from getting too dry?
I make sure to measure the ingredients correctly and avoid overbaking. Using fresh blueberries also helps add moisture.
Can I make these bars vegan?
Yes! I replace the egg with a flax egg (1 tablespoon flaxseed meal + 3 tablespoons water) and use a plant-based milk option.
Can I use quick oats instead of rolled oats?
Yes, but the texture will be a bit softer since quick oats absorb liquid differently.
What’s the best way to cut the bars cleanly?
I let them cool completely and use a sharp knife. Sometimes, I even chill them for 15 minutes before cutting.
Can I add protein powder?
Absolutely! I mix in a scoop of vanilla or unflavored protein powder and slightly increase the applesauce or milk to keep the texture moist.
Conclusion
These Blueberry Oatmeal Breakfast Bars are one of my favorite make-ahead breakfasts. They’re easy to whip up, customizable, and packed with wholesome ingredients. Whether I enjoy them fresh or from the freezer, they’re a delicious and nutritious way to start the day.
