Healthy Blueberry Oatmeal Bars
We should note that these bars are not overly sweet, with minimal sugar and whole grains. However, they are still incredibly delicious with the crumbly topping and baked blueberries!
One of the reasons we like them so much - Oats! Oats are among the healthiest grains on earth. They're a gluten-free whole grain and a great source of essential vitamins, minerals, fiber, and antioxidants.
We're always looking for healthy snacks for the kiddos, so you can't go wrong when you bake oats into a bar, and it tastes this good!

Step By Step Instructions
This recipe comes together with one bowl and one pan with a few simple steps!
Step 1 - Prepare Crust and Topping
First, preheat the oven to 350 degrees F. and line your pan with parchment. Next, place all your dry ingredients for the main recipe, including rolled oats and ½ cup honey, plus the melted butter and vanilla extract, in a large bowl and mix.
Now, reserve 1 cup of the oat mixture, place the rest in the prepared pan, and pat down.
Tip: you can also add a little lemon zest to the recipe for added lemon flavor.
Step 2 - Prepare Blueberry Filling
Next, place the washed blueberries, lemon juice, cornstarch, and coconut sugar (if you prefer, use regular granulated sugar) in the bowl you used for the oat mixture.
Stir to combine.
Step 3 - Layer Ingredients in Pan & Bake
Next, place the blueberries on top of the oat mixture in the pan. Crumble the reserved cup of the oat mixture over the blueberries and place it in the oven for 45 minutes.
Tip: Since oven temperatures vary, check your oatmeal bars during the last few minutes of cooking to make sure they don't overcook.
Finally, let it cool completely before taking it out of the pan.
Get ready for your house to smell amazing!
Can You Use Frozen Blueberries?
A great question that's often asked, especially when blueberries are not in season. Yes, you can use frozen blueberries in this oat bar recipe.
They contain more water content when frozen, so we recommend adding a teaspoon of cornstarch to the berries before adding the topping.
Vegan Blueberry Bars
Make the bars as instructed with these ingredients. They turn out great! If you'd like to make a vegan version of this bar, follow these substitutions:
- Substitute coconut oil for the butter.
- Use maple syrup instead of honey.

Turned out very dry, needs a little extra something - applesauce? Even water? Would have been nice to have some more chewiness or cohesiveness.
Erin Henry says
It's more of a crumb topping, so on the dryer side. Make sure you don't over bake as it will become dry.
