To make lemon blueberry crumb bars, you need a simple list of ingredients. Each item plays a key role in creating that bright, zesty flavor and perfect crumbly texture. Here’s what you’ll need: - 1 ¾ cups all-purpose flour - ¾ cup granulated sugar - ½ cup unsalted butter, softened - 1 large egg - 1 teaspoon vanilla extract - 1 teaspoon baking powder - ½ teaspoon salt - Zest of 1 lemon - 1 cup fresh blueberries - 2 tablespoons fresh lemon juice - ½ teaspoon ground cinnamon - ½ cup old-fashioned oats - ¼ cup brown sugar Using high-quality ingredients makes a big difference. Fresh blueberries are key for flavor, while lemon zest adds that bright note. Don't skip the oats; they add a nice texture to the crumb topping. {{ingredient_image_1}} First, set your oven to 350°F (175°C). This heat makes the bars bake perfectly. While it warms up, you can focus on getting your dish ready. In a big bowl, mix softened butter with granulated sugar. Use a mixer or a spoon. Beat it until it feels light and fluffy. Then, add in the egg, vanilla extract, and lemon zest. Mix until it blends well. In another bowl, whisk together the all-purpose flour, baking powder, and salt. This step is key for good texture. Slowly add this dry mix to the wet mix. Stir until just combined. Don't over-mix! Take the dough and scoop it into the prepared baking dish. Press it down evenly to form your crust. Bake this base for about 15 to 20 minutes. Look for a light golden color. In a medium bowl, toss the fresh blueberries with lemon juice and ground cinnamon. Make sure every berry gets coated. Spread these blueberries over the baked crust evenly. In a separate bowl, combine the oats, brown sugar, and any leftover flour. Add a bit of the crust mixture. This will help form crumbs. Sprinkle this crumb mix over the blueberries. Put the baking dish back in the oven. Bake for another 25 to 30 minutes. You want the topping to be golden brown and see the blueberries bubbling. Once baked, take it out of the oven. Let it cool completely in the pan on a wire rack. When cool, lift the bars out using the parchment paper. Slice into squares and enjoy! To make the best lemon blueberry crumb bars, follow these tips: - Use fresh blueberries: They give the best taste and texture. - Cream the butter and sugar well: This step adds air to the mixture, making your bars light. - Don’t overmix the batter: Mix until just combined to keep the texture tender. - Cool completely before slicing: This helps the bars hold their shape when cut. These bars shine when served right. Here are some ideas: - Dust with powdered sugar: This adds sweetness and a pretty look. - Top with lemon zest: It brightens the flavor and adds color. - Serve with fresh blueberries: A side of berries makes for a lovely presentation. - Pair with whipped cream or ice cream: This adds creaminess and a fun twist. Want to tweak the sweetness of your bars? Here’s how: - Start with less sugar: Use ½ cup of sugar instead of ¾ cup for a lighter taste. - Add more lemon juice: This will brighten the flavor and balance the sweetness. - Try a sugar substitute: Use honey or maple syrup for a natural alternative. - Taste before baking: Adjust the sweetness to your liking, but remember, the final taste will be less sweet after baking. Pro Tips Use Fresh Blueberries: For the best flavor and texture, always opt for fresh blueberries. They will burst with flavor and create a juicy filling. Chill the Dough: If your crust mixture feels too soft to handle, chill it in the refrigerator for about 15 minutes before pressing it into the pan. This will help it firm up and make it easier to work with. Check for Doneness: The crumb topping should be golden brown, and the blueberries should be bubbling. Use a toothpick to check the crust; it should come out clean when inserted. Store Properly: To keep your bars fresh, store them in an airtight container in the refrigerator for up to a week. They can also be frozen for longer storage. {{image_2}} You can switch up the blueberries for other fruits. Raspberries and blackberries work great. Cherries, diced peaches, or strawberries also add fun flavors. Each fruit brings a new twist. Just remember to adjust the sugar. Some fruits are sweeter than blueberries. To make these bars vegan, replace the egg with flaxseed meal. Mix 1 tablespoon of flaxseed meal with 2.5 tablespoons of water. Let it sit for five minutes until it thickens. Use coconut oil instead of unsalted butter. This keeps the bars rich and tasty without dairy. If you need gluten-free bars, use almond or oat flour. These flours can replace all-purpose flour easily. Just ensure your oats are gluten-free if you choose to use them. You may need to adjust the amount of flour slightly. Start with less and add more if needed. To keep your lemon blueberry crumb bars fresh, place them in an airtight container. Store them at room temperature for up to three days. If you want to keep them longer, the fridge is a great option. They can last up to a week when chilled. Just remember to let them cool completely before storing. You can freeze these bars for later enjoyment. Once cooled, cut them into squares. Wrap each piece tightly in plastic wrap or foil. Place the wrapped bars in a freezer-safe bag. They will stay fresh for up to three months. When ready to eat, just thaw them in the fridge overnight. To enjoy your bars warm, you can reheat them in the oven. Preheat the oven to 350°F (175°C). Place the bars on a baking sheet and cover them with foil. Heat for about 10-15 minutes. If you prefer the microwave, heat one square at a time for about 10-15 seconds. This will bring back their soft texture and warm flavor. Yes, you can use frozen blueberries. Just keep them frozen until you mix them into the batter. This helps them hold their shape. If you thaw them first, they may get mushy. Adjust the baking time if needed, but they should work well. Lemon blueberry crumb bars last about five days at room temperature. Store them in an airtight container. They can also last up to two weeks in the fridge. Just make sure they are sealed well to keep them fresh. You can use other citrus fruits like lime or orange. Each fruit will give a different taste. Lime adds a nice zing, while orange brings sweetness. Just use the same amount of juice and zest in your recipe. The best way to cut the bars is when they are fully cool. Use a sharp knife for clean cuts. Start at the center and slice outwards. For neat edges, wipe the knife between cuts. Enjoy the perfect squares!
