Enjoy the process, and feel free to explore substitutions based on your taste! First, preheat your oven to 350°F (175°C). This step is very important. A proper oven temperature helps the bars bake evenly. While the oven heats, prepare an 8x8-inch baking dish. You can grease it lightly with butter or use parchment paper. Lining the dish makes it easier to lift the bars out later. In a large mixing bowl, combine the following dry ingredients: - 2 cups rolled oats - 1 cup all-purpose flour - 1/2 cup packed brown sugar - 1/4 cup granulated sugar - 1 teaspoon baking powder - 1/2 teaspoon salt Mix these well until everything is evenly combined. This mix gives the bars their base flavor. Now, let's add the wet ingredients. Pour in: - 1/2 cup unsalted butter, melted - 1/4 cup honey or maple syrup - 1 teaspoon vanilla extract Use a spatula or your hands to mix everything together. You want a crumbly texture that sticks together when pressed. Set aside 1 cup of this mixture for the crumble topping later. In a separate bowl, take 2 cups of fresh or frozen blueberries. Toss them with: - 1 tablespoon cornstarch - 1 tablespoon lemon juice This step helps the blueberries not to get too runny. Make sure the berries are well coated. Next, press the blueberry-oat mixture firmly into the bottom of your prepared baking dish. This creates a nice base. Now, sprinkle the reserved crumble topping evenly over the blueberries. Bake in the preheated oven for about 25-30 minutes. You will know they are done when the top turns golden brown and the blueberries bubble slightly. To get the best crumble texture, focus on mixing. Combine your dry ingredients first. This will help evenly distribute the sugar and baking powder. When adding wet ingredients, pour in melted butter slowly. Mix gently until the mixture feels crumbly. If it feels too dense, add a bit more melted butter. For a lighter crumble, use less pressure when mixing. You want it to hold together but not be compact. You can easily swap ingredients based on what you have. For sugar, try coconut sugar or maple sugar. These can add a rich flavor. If you want to cut back on butter, use coconut oil or applesauce. Both work well in this recipe. For honey, maple syrup is a great alternative. It adds a unique taste. Feel free to experiment with these options. These bars taste amazing on their own, but you can elevate them. Serve with a scoop of vanilla ice cream for a sweet treat. A dollop of whipped cream also works well. You can sprinkle some nuts on top for extra crunch. For a fresh touch, add a few mint leaves. Drizzling honey or maple syrup on top can give it a nice finish. Enjoy your creation with friends or family! {{image_4}} You can easily change the flavor of your oatmeal base. Adding spices like cinnamon or nutmeg gives a warm taste. Try adding one teaspoon of cinnamon for a cozy feel. Nutmeg adds a hint of spice that contrasts well with the sweetness of blueberries. Mix the spices into the dry ingredients for an even blend. If you want a twist on the classic recipe, use different fruits. Raspberries or peaches work well and add unique flavors. Raspberries give a tart contrast to the sweet crumble. Peaches add a juicy sweetness that pairs nicely with oats. Just ensure you adjust the sugar if using sweeter fruits. You can make these bars vegan by replacing butter with coconut oil or vegan butter. For binding, use flaxseed meal mixed with water instead of eggs. This gives a nice texture and holds everything together. To make it gluten-free, swap all-purpose flour for almond flour or a certified gluten-free blend. These changes keep the bars tasty and suitable for everyone. For the full recipe, visit the link. To keep your Blueberry Oatmeal Crumble Bars fresh, use an airtight container.

Ingredients
  

2 cups rolled oats

1 cup all-purpose flour

1/2 cup packed brown sugar

1/4 cup granulated sugar

1 teaspoon baking powder

1/2 teaspoon salt

1/2 cup unsalted butter, melted

1/4 cup honey or maple syrup

1 teaspoon vanilla extract

2 cups fresh or frozen blueberries

1 tablespoon cornstarch

1 tablespoon lemon juice

Instructions
 

Begin by preheating your oven to 350°F (175°C). Prepare an 8x8-inch baking dish by greasing it lightly or lining it with parchment paper for easier removal of the bars later.

    In a large mixing bowl, combine the rolled oats, all-purpose flour, brown sugar, granulated sugar, baking powder, and salt. Stir these dry ingredients well until they're evenly mixed.

      Pour in the melted butter, followed by the honey (or maple syrup) and vanilla extract. Using a spatula or your hands, mix everything together until you have a crumbly texture that holds together when pressed. Set aside 1 cup of this mixture to use later as the crumble topping.

        In a separate bowl, add the blueberries and toss them with cornstarch and lemon juice until they are well coated. Gently fold the blueberries into the remaining oat mixture, being careful not to break the berries.

          Press the blueberry-oat mixture firmly and evenly into the bottom of your prepared baking dish, creating a solid base.

            Evenly distribute the reserved crumble mixture over the blueberries, ensuring that it covers them well for a delightful texture contrast.

              Place the dish in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and you see the blueberries bubbling slightly.

                Once baked, remove the bars from the oven and allow them to cool in the pan for at least 15 minutes. Carefully lift the bars out using the edges of the parchment paper, and once completely cooled, slice into squares.
