- 2 cups all-purpose flour - 1 cup rolled oats - 1 cup brown sugar, packed - 1/2 teaspoon baking soda - 1/2 teaspoon salt - 1 cup unsalted butter, melted - 2 cups fresh blueberries - 1/4 cup granulated sugar - 3 tablespoons lemon juice - Zest of 1 lemon - 1 tablespoon cornstarch - 1 teaspoon vanilla extract To make great Lemon Blueberry Crumb Bars, you need to measure well. Use a dry measuring cup for flour and oats. Spoon ingredients into the cup and level off with a knife. This method gives you the right amount without packing it down. For butter, use a liquid measuring cup for melted butter. Weight measurements can also help. A kitchen scale can give you the exact amount of flour and butter. This is helpful for new cooks and ensures consistent results. You can make these bars gluten-free. Use a gluten-free flour blend instead of all-purpose flour. This keeps the texture nice and crumbly. For a vegan option, swap the butter for coconut oil or vegan butter. Use a flax egg instead of the regular egg, if needed. You can mix 1 tablespoon of ground flaxseed with 3 tablespoons of water. Let it sit for a few minutes to thicken. These swaps keep the bars tasty while meeting different diets. 1. Start by greasing your 9x13-inch baking dish. This helps the bars come out easily. 2. Preheat your oven to 350°F (175°C) so it's ready when you are. 3. In a large bowl, mix together the flour, oats, brown sugar, baking soda, and salt. 4. Pour in the melted butter and stir until you have a mixture that looks like wet sand. 1. Reserve 1 cup of the crumb mixture for the topping. 2. Press the remaining crumb mixture evenly into the bottom of your prepared baking dish. This will be your crust. 3. In another bowl, combine the fresh blueberries, granulated sugar, lemon juice, lemon zest, and cornstarch. Stir gently to coat the blueberries evenly. 4. Spread the blueberry filling over the crust in the baking dish. 5. Crumble the reserved topping mixture over the blueberries. Make sure it covers evenly for a nice bite. 1. Bake the bars in your preheated oven for 30-35 minutes. Look for a golden brown topping and bubbling blueberries. 2. To test for doneness, insert a toothpick in the center. If it comes out clean, your bars are ready. 3. Allow the bars to cool completely in the pan before slicing them into squares. This will help them hold their shape. To get the best crumb texture, focus on the butter. It should be melted but not hot. Mix it with the dry ingredients until it looks like wet sand. This will help your bars hold together well. To avoid soggy bottoms, make sure to press the crust firmly into the dish. This creates a solid base. Also, bake the crust for about 10 minutes before adding the blueberries. This helps set it and keeps it crisp. These lemon blueberry crumb bars shine when paired with ice cream. A scoop of vanilla ice cream on the side adds a creamy touch. You can also use whipped cream for a lighter option. For parties, present your bars on a bright platter. Dust with powdered sugar for a sweet look. Garnish with lemon slices and extra blueberries for color. This will make your dessert pop! Include clear, bright images of your finished bars. Show the layers to highlight their texture. You can also share a video of the preparation process. This helps readers feel more connected to the recipe. Good visuals grab attention and keep readers interested. They make your recipe blog stand out and encourage others to try your bars. {{image_2}} You can play with flavors to make these bars even more fun. Adding spices like cinnamon or nutmeg gives a warm touch. Just a pinch can change the whole flavor. You can add one teaspoon of cinnamon to the crumb mix. This simple tweak makes a cozy dessert. Another great idea is to mix in other fruits. Raspberries pair well with blueberries. They add a nice tartness. You can substitute half of the blueberries with raspberries. This mix will make your bars pop with color and flavor. If you want a lower sugar option, you can cut down on brown sugar. Use just half a cup instead of a full cup. You can also replace some sugar with unsweetened applesauce. It keeps the bars moist without the extra sugar. For those with nut allergies, this recipe is nut-free. Just stick to the ingredients listed. Ensure that your oats are certified nut-free. This way, everyone can enjoy these tasty treats. Feeling adventurous? Try making a lemon blueberry crumble pie. Use your same crust and filling but place it in a pie dish. The pie form adds a whole new way to enjoy this flavor. You can also create muffin versions of the crumb bars. Just pour the mixture into muffin tins instead of a baking dish. Bake them for about 20-25 minutes. These lemon blueberry muffins will be cute and easy to grab on the go.

Just store them in an airtight container at room temperature. They stay fresh and tasty for about three days. How can I adjust the sweetness level?
