They enhance flavor and texture. I always choose fresh blueberries when in season. They burst with flavor and add a nice pop of color. The zest of a fresh lemon brings a bright taste. It gives your bars a refreshing twist. Don't skip the brown sugar; it adds depth and a hint of caramel flavor. The rolled oats give the crumble a nice chew and texture. - Additional spices (e.g., cinnamon) - Different fruit combinations - Vegan substitutes for butter Feel free to experiment with your ingredients. A dash of cinnamon can add warmth. You can mix in other fruits like raspberries or strawberries for variety. If you prefer a vegan version, swap out the butter for a plant-based option.

If it looks cooked and smells good, it’s ready. - Adjusting sweetness as per preference: Taste the blueberry mix before adding it to the crust. If you like it sweeter, add a bit more sugar. You can also cut back if you prefer less sweetness. - Ensuring even distribution of blueberries: Spread the blueberries evenly over the crust. This helps every bite to have that juicy blueberry flavor. Use a spatula to help spread them out gently. - Presentation tips for serving: Arrange the bars on a nice plate. Dust with powdered sugar for a fancy touch.

The tart lemon and sweet blueberries complement these drinks nicely. Pro Tips Use Fresh Ingredients: For the best flavor, opt for fresh blueberries and freshly squeezed lemon juice. This will enhance the overall taste of the crumble bars. Chill the Dough: If time allows, chill the crumble mixture in the refrigerator for about 30 minutes before baking. This helps to create a better texture and crumbly topping. Experiment with Flavors: Feel free to mix in other berries like raspberries or blackberries, or add spices like cinnamon for an extra flavor boost. Store Properly: Keep the bars in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate them, and they can last up to a week. {{image_4}} You can mix up the fruit in these bars. Raspberries, strawberries, and blackberries work well. Each fruit gives a unique taste to the crumble bars. You can even make a mixed berry crumble. Just use a blend of your favorite berries. This adds fun colors and flavors, making each bite exciting. If you need gluten-free options, try using almond flour or oat flour. Both will give you a great base for your bars. For those who follow a vegan diet, swap butter for coconut oil or a plant-based spread. Use a sweetener like maple syrup instead of sugar. These changes keep the taste great while fitting your diet. To keep your Lemon Blueberry Crumble Bars fresh, store them in an airtight container. This step helps prevent them from becoming dry. Keep the container at room temperature for up to three days.

Yes, you can use frozen blueberries. Just make sure to thaw them first. This helps the filling mix well. How do I know when the bars are done baking? Look for a golden brown top.

Ingredients
  

  • 1 cup all-purpose flour
  • 1 cup rolled oats
  • 0.5 cup brown sugar, packed
  • 0.5 teaspoon baking powder
  • 0.25 teaspoon salt
  • 0.5 cup unsalted butter, melted
  • 1 cup fresh blueberries (or frozen, thawed)
  • 1 unit zest of 1 lemon
  • 2 tablespoons fresh lemon juice
  • 0.25 cup granulated sugar
  • 1 tablespoon cornstarch

Instructions
 

  • Begin by preheating your oven to 350°F (175°C). Prepare an 8x8-inch baking pan by greasing it lightly or lining it with parchment paper, which will allow for easy removal later.
  • In a medium mixing bowl, combine the all-purpose flour, rolled oats, brown sugar, baking powder, and salt. Use a whisk or a fork to thoroughly mix the dry ingredients together.
  • Pour in the melted butter, and mix until the ingredients form a crumbly texture. Set aside 1 cup of this mixture to be used as the topping. Press the remaining crumble mixture evenly into the bottom of the prepared baking pan, creating a firm crust. Bake in the preheated oven for 10 minutes until lightly set.
  • While the crust is baking, prepare the blueberry filling. In a separate medium bowl, combine the fresh blueberries, lemon zest, lemon juice, granulated sugar, and cornstarch. Gently toss the mixture until the blueberries are well-coated with the other ingredients, being careful not to mash the berries.
  • After the crust has baked for 10 minutes, remove it from the oven. Evenly spread the blueberry filling over the baked crust, ensuring the blueberries are distributed well.
  • Take the reserved crumble mixture and sprinkle it generously over the blueberry layer to create a delightful crumble topping.
  • Return the pan back to the oven and bake for an additional 25-30 minutes, or until the topping turns a lovely golden brown and the blueberry filling is bubbling and fragrant.
  • Once baked, remove the pan from the oven and allow it to cool completely on a wire rack within the pan. Once cooled, carefully cut into square bars for serving.

Notes

Arrange the bars on a decorative serving plate. For an elegant finish, dust with powdered sugar and garnish with a handful of extra blueberries and a lemon wedge.
