Another reason to love this recipe is its simple ingredient list. It uses pantry-friendly staples and frozen blueberries, so you can make it any time of year without needing fresh seasonal fruit.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
2 1/2 cups old-fashioned rolled oats
1 cup frozen blueberries
1/2 cup cashew butter
1/4 cup maple syrup
1 teaspoon almond extract
1/2 cup frozen blueberries
1/2 cup sliced almonds
Directions
Preheat your oven to 350°F (180°C). Line an 8-inch pan with parchment paper, then lightly coat the parchment with cooking oil spray and set the pan aside.
Place 1 cup of frozen blueberries in a microwave-safe bowl and microwave for 1 minute on high, just until thawed and slightly warm. You should notice a bit of blueberry juice at the bottom of the bowl.
Add the oats, thawed blueberries, cashew butter, maple syrup, and almond extract to a food processor. Blend on high speed until the mixture forms a thick, sticky batter. Stop to scrape down the sides as needed so everything blends evenly. If the batter seems too wet, add a little more oats and blend again.
Transfer the batter to the prepared pan and spread it into an even layer. Because the mixture is sticky, a rubber spatula works especially well for smoothing the top.
Sprinkle the sliced almonds evenly over the surface and gently press them into the batter so they stick. Scatter the remaining 1/2 cup frozen blueberries on top and lightly press each one into the surface.
Bake for 30 minutes, or until the almonds are lightly toasted and the bars look set and dry on top.
Let the bars cool in the pan for 10 minutes before lifting them out and placing them on a cooling rack. Slice and serve once they have cooled slightly. These bars are soft-baked rather than crunchy, and they pair especially well with a dollop of yogurt.
Servings and timing
This recipe makes 9 servings.
The total time is 40 minutes. That includes about 10 minutes of preparation and 30 minutes of baking time.
Variations
For a different nutty flavor, swap the cashew butter for almond butter or peanut butter. Each option gives the bars a slightly different taste while keeping the texture rich and soft.
You can also change the fruit. Raspberries, chopped strawberries, or blackberries work well in place of blueberries. For a warmer flavor profile, try mixing in a little cinnamon along with the almond extract.
If you want extra texture, stir in shredded coconut, chopped walnuts, or sunflower seeds. For a sweeter dessert-style version, a handful of white chocolate chips can make these bars feel a little more indulgent.
Storage/Reheating
Store the bars in an airtight container in the refrigerator for up to 5 days. Keeping them chilled helps maintain their soft texture and makes them easier to slice and handle.
For longer storage, freeze the bars in a single layer or with parchment between the slices in a freezer-safe container for up to 2 months. Thaw them in the refrigerator or at room temperature before serving.
To reheat, warm an individual bar in the microwave for a few seconds until just soft. They can also be enjoyed cold or at room temperature.
FAQs
Can I use fresh blueberries instead of frozen blueberries?
Yes, fresh blueberries can be used. Keep in mind that frozen blueberries release more moisture when thawed, so fresh berries may slightly change the texture.
Do I need a food processor for this recipe?
A food processor works best because it breaks down the oats and blends everything into a sticky batter. A high-powered blender may also work, but you may need to stop often and scrape the sides.
Can I make these bars gluten-free?
Yes, as long as you use certified gluten-free rolled oats, the bars can be made gluten-free.
Are these bars crunchy or soft?
These bars are soft-baked, tender, and chewy rather than crisp or crunchy.
Can I make them sweeter?
Yes, you can increase the maple syrup slightly or add a few sweet mix-ins such as chocolate chips or dried fruit.
What can I use instead of cashew butter?
Almond butter, peanut butter, or sunflower seed butter are all good substitutes.
Why is my batter too wet?
This can happen if the blueberries release extra liquid. Add a little more oats and blend again until the batter becomes thick and sticky but not runny.
Can I add spices to the batter?
Yes, cinnamon is a great addition. A small pinch of nutmeg can also work well with the blueberry flavor.
How should I serve these bars?
They are delicious on their own, but they are especially good served on a plate with a spoonful of yogurt.
Can I freeze Blueberry Oat Bars?
Yes, these bars freeze very well. Wrap them individually or store them in layers with parchment paper between them for easy grab-and-go portions.

Blueberry Oat Bars are a simple, wholesome recipe that delivers plenty of flavor with very little effort.
