Ingredients
List of Key Ingredients
– Rolled oats
– Whole wheat flour
– Brown sugar
– Unsalted butter
The key ingredients make these blueberry oatmeal crumble bars rich and tasty. Rolled oats give a chewy texture. Whole wheat flour adds a nutty taste. Brown sugar brings sweetness and depth. Unsalted butter keeps the crust soft and flavorful.
Optional Ingredients

Substitutions
– Frozen blueberries instead of fresh

If you don’t have fresh blueberries, use frozen ones. Just thaw them first. For gluten-free options, try almond flour or oat flour. These swaps keep the bars delicious while meeting different dietary needs.
Step-by-Step Instructions
Preparing the Baking Pan
First, preheat your oven to 350°F (175°C). This step is key for even baking. Next, take an 8×8-inch baking pan and line it with parchment paper. Leave some paper hanging over the sides. This makes it easy to lift the bars out later.
Making the Crust
In a large mixing bowl, combine the following ingredients:
– 2 cups rolled oats
– 1 cup whole wheat flour
– 1/2 cup packed brown sugar
– 1/2 cup unsalted butter, melted
– 1/2 teaspoon baking soda
– 1/2 teaspoon salt
– 1 teaspoon pure vanilla extract
Mix these ingredients well until you get a crumbly texture. The mixture should hold together but still look loose.
Assembling the Bars
Take about two-thirds of the oat mixture and press it firmly into the bottom of your lined baking pan. This will be your crust.
In a separate bowl, mix together 2 cups of fresh blueberries, 1 tablespoon of fresh lemon juice, and 1 tablespoon of cornstarch. If you want extra sweetness, add 1 tablespoon of honey or maple syrup. Gently fold the blueberries until they are covered.
Spread the blueberry mixture evenly over the crust in your baking pan. Make sure to cover the entire surface. Then, crumble the remaining oat mixture over the blueberries. This will be your topping.
Bake the bars in your preheated oven for 30-35 minutes. They are done when the top is golden brown and the blueberries bubble. After baking, let them cool in the pan for about 10 minutes. Then, lift them out using the parchment paper.
Place the bars on a wire rack to cool completely. Once cool, cut them into squares or rectangles for serving.
Tips & Tricks
Baking Tips
To get that perfect golden brown crust, start by pressing the oat mixture firmly into the pan. This helps it hold together well. Bake the bars until the top is golden and the blueberries bubble. Look for a nice color change; this means they are ready. If you see the blueberries bubbling, you know they are cooked through.
Cooling and Cutting
After baking, let the bars cool for at least 10 minutes in the pan. This helps them set. For best results, transfer them to a wire rack to cool completely. When cutting, use a sharp knife for clean edges. You can cut them into squares or rectangles.
Presentation Suggestions
To serve, arrange the bars on a nice platter. Dust them lightly with powdered sugar for a sweet touch. Add some fresh blueberries around the bars for color. For a special treat, serve with a scoop of vanilla ice cream. This makes the bars even more enjoyable.

Variations
Flavor Variations
You can change up the taste of your blueberry oatmeal crumble bars with some fun add-ins. Adding nuts like walnuts or almonds gives a nice crunch. You can also add seeds, like sunflower seeds, for extra texture. Spices can really elevate your bars too. Try adding a sprinkle of cinnamon or nutmeg for warmth. These small changes can make a big difference in flavor.
Dietary Variations
If you want a vegan version, use plant-based butter instead of regular butter. This small swap keeps the bars tasty while meeting dietary needs. For those who need gluten-free options, use gluten-free oats and flour. This ensures everyone can enjoy these delicious treats without worry.
Seasonal Fruit Alternatives
While blueberries are the star, you can switch them out for other fruits. Strawberries, raspberries, or peaches work well too. Each fruit brings its own unique taste. You can even mix different fruits for a fun twist. This flexibility lets you enjoy these bars all year round.
Storage Info
Room Temperature Storage
You can keep your blueberry oatmeal crumble bars at room temperature for 2 to 3 days. Make sure to store them in an airtight container. This way, they stay fresh and tasty.
Refrigeration
For longer freshness, store the bars in the fridge. Use a container that seals tightly. They can last up to a week when stored this way. Just remember to let them sit out for a bit before you enjoy them. This helps bring back their soft texture.
Freezing Instructions
To freeze these bars, cut them into squares first. Wrap each square in plastic wrap, then place them in a freezer-safe bag. You can freeze them for up to 3 months. When you’re ready to eat, take them out and let them thaw in the fridge overnight. For a quick warm-up, pop them in the microwave for a few seconds. Enjoy your treat any time!

In a large mixing bowl, combine all these fruits. Gently mix them to spread the flavors evenly. This step helps each fruit shine in the salad. Next, we make the dressing. In a separate bowl, add a quarter cup of honey, two tablespoons of freshly squeezed lime juice, and the zest of one lime. I like to whisk these together until the mixture is smooth. This dressing adds a sweet and zesty kick to the salad. Now, it's time to bring it all together. Drizzle the honey-lime dressing over your prepared fruits. Toss everything gently with a spatula or large spoon. Make sure each piece of fruit gets coated in the dressing. Let the salad sit for about ten minutes at room temperature. This resting time lets the flavors blend beautifully. Enjoy your fresh and colorful Honey Lime Fruit Salad! You can find the Full Recipe for details on preparation. To make a great Honey Lime Fruit Salad, choose ripe, seasonal fruits. Fresh fruits provide the best taste and texture. Look for strawberries with bright red color. Blueberries should be plump and firm. Pick mangoes that give slightly when you press them. Pineapples should smell sweet at the base. Bananas need to be ripe but not brown. When you select these fruits, you ensure a delightful salad. Let your salad rest for at least 10 minutes before serving. This short wait helps the flavors blend. The honey lime dressing seeps into the fruits. This makes each bite burst with flavor. The longer the salad sits, the better it tastes. You can prepare this ahead of time for easy serving.

Always check for changes in smell or texture. Freezing fruit salad can change its texture. If you want to freeze it, use firm fruits like pineapple and mango. Avoid bananas, as they turn mushy. To freeze, place the salad in a freezer-safe container. When ready to eat, let it thaw in the fridge. You can also add fresh honey-lime dressing after defrosting for extra flavor. Yes, you can use frozen fruits in this salad. Frozen fruits can be a great option when fresh fruits are out of season. They are often picked at their peak and frozen right away, keeping their nutrients intact. However, frozen fruits can release more water as they thaw. This might make the salad a bit watery. To avoid this, let the frozen fruits thaw and drain excess liquid before mixing them in. Fresh fruits offer a crunchier texture and vibrant look, so choose based on your preference. No, this salad is not vegan due to honey. Honey comes from bees, making it an animal product. If you want a vegan option, you can easily replace honey with agave syrup or maple syrup.

Just make sure to use the same amount of the substitute for the best flavor balance. This fruit salad is packed with vitamins and minerals.
