Ingredients Breakdown
For the Crust and Crumble
The base and topping are made from the same mixture, which saves time and effort.
- Rolled oats provide a hearty texture and are rich in fiber
- Almond flour adds a nutty flavor and keeps the bars gluten-friendly

- Sweetener balances the tartness
- Vanilla extract rounds out the taste
Step-by-Step Instructions
Start by preheating your oven to 350°F (175°C) and lining an 8×8-inch baking pan with parchment paper. This will make it easier to remove and slice the bars later.
In a large mixing bowl, combine the rolled oats, almond flour, whole wheat flour, sweetener, cinnamon, and salt. Stir everything together until well mixed. Then add the melted coconut oil (or butter) and vanilla extract. Mix until the mixture becomes crumbly and holds together when pressed.
Take about two-thirds of this mixture and firmly press it into the bottom of your prepared baking pan. This will form the crust of your bars.
Next, prepare the blueberry filling. In another bowl, mix the blueberries, chia seeds, lemon juice, sweetener, and vanilla extract. Stir well until everything is evenly coated.
Spread the blueberry mixture over the crust, making sure it’s evenly distributed. Then sprinkle the remaining oat mixture on top to create the crumble layer.
Place the pan in the oven and bake for 30 to 35 minutes, or until the top is golden brown and slightly crisp.
Once baked, remove the pan from the oven and allow it to cool completely. This step is very important, as it helps the bars set properly and makes slicing much easier.
Tips for Perfect Bars
To get the best results, keep these tips in mind:
- Let them cool completely before cutting. This helps them hold their shape
- Use fresh blueberries for a firmer texture, or frozen for a softer filling
- Add chopped walnuts or almonds for extra crunch
- Adjust sweetness based on your taste preference
- Store leftovers in the fridge for better texture and longer freshness
Storage and Serving Suggestions
These bars are perfect for meal prep. Once cooled and sliced, you can store them in an airtight container in the refrigerator for up to 5 days. They also freeze well, so you can make a batch ahead of time and enjoy them whenever you want.
Serve them as:
- A quick breakfast with tea or coffee
- A healthy afternoon snack
- A light dessert after dinner
You can even warm them slightly and serve with a dollop of yogurt for an extra treat.
