- 2 cups fresh blueberries - 1 tablespoon lemon juice - Zest of 1 lemon - 1 cup all-purpose flour - 1 cup rolled oats - 3/4 cup brown sugar, packed - 1/2 teaspoon baking powder - 1/4 teaspoon salt - 1/2 cup unsalted butter, softened - 1 teaspoon vanilla extract In this recipe, fresh blueberries are key. They add sweetness and a burst of flavor. You can also use frozen blueberries if you prefer. Just make sure to thaw them first and drain excess moisture. The lemon juice and zest give a bright taste that balances the sweetness of the blueberries. For the dry mix, you will need all-purpose flour, rolled oats, brown sugar, baking powder, and salt. The oats add texture and a nice crunch, while brown sugar provides depth in flavor. Baking powder helps the bars rise, and salt enhances all the flavors. The last ingredients are butter and vanilla extract. The butter binds everything together, giving a rich flavor. Vanilla adds warmth and rounds out the taste profile. Gather these ingredients to start making your Blueberry Lemon Crumble Bars. Each one plays an important role in creating the perfect blend of sweet and tart. Enjoy the process of mixing them together for a delightful treat! First, preheat your oven to 350°F (175°C). Line an 8x8 inch baking dish with parchment paper. Leave some paper hanging over the edges. This helps with easy removal later. In a medium bowl, combine 2 cups of fresh blueberries with 1 tablespoon of lemon juice and the zest of 1 lemon. Stir gently and set this aside. Letting the mixture sit helps the flavors blend nicely. In a large mixing bowl, mix together 1 cup of all-purpose flour, 1 cup of rolled oats, 3/4 cup of packed brown sugar, 1/2 teaspoon of baking powder, and 1/4 teaspoon of salt. These dry ingredients are key for a tasty crumble. Next, cut in 1/2 cup of softened unsalted butter. You can use a pastry cutter or your fingers. Mix until it looks like coarse crumbs. Finally, add in 1 teaspoon of vanilla extract and stir until combined. Now, take half of your crumble mixture and press it firmly into the bottom of the prepared baking dish. This forms the base layer. Evenly spread the blueberry mixture over the crumble base. Make sure the blueberries are spread out well. Sprinkle the remaining crumble mixture on top. This will cover the blueberries while leaving some visible for texture. Place the baking dish in the oven and bake for 30-35 minutes. Look for a golden brown top and bubbling blueberries. This shows they are done. When baked, remove the dish from the oven. Let it cool completely in the dish on a wire rack. This cooling step helps the bars set. Once cool, lift the edges of the parchment paper and take the bars out. Cut them into squares and enjoy! To get a crunchy crumble topping, use cold butter. Cold butter helps keep the crumbs firm. Cut the butter into your dry mix until it looks like sand. Don’t overwork it. The mix should feel crumbly, not smooth. Press half of the crumble into the pan, but keep the top layer loose. This helps it bake up nice and crunchy. To boost flavor, add spices like cinnamon or nutmeg. A pinch of cardamom also works well. For extra texture, toss in chopped nuts like walnuts or pecans. You can even add a handful of coconut flakes. These simple changes will make your bars even more delicious. Serve the Blueberry Lemon Crumble Bars warm or at room temperature. Adding a scoop of vanilla ice cream on top makes for a tasty treat. You can also drizzle some lemon glaze for extra zest. Cut the bars into small squares for easy serving. Enjoy with family or friends for a sweet gathering! {{image_2}} You can easily switch blueberries for other fruits. Raspberries, strawberries, or blackberries work great. Each fruit adds its own flavor. For a tart twist, try cranberries. Mix and match for fun combinations. Just keep the same amount of fruit. The filling will still be juicy and tasty. If you want to change the sweetener, honey or maple syrup are good choices. Use the same amount as brown sugar. Honey gives a floral taste, while maple syrup adds a rich flavor. Both options keep the bars sweet and moist. You can try them based on what you have at home. To make gluten-free Blueberry Lemon Crumble Bars, swap all-purpose flour for gluten-free flour.
