• 2 tablespoons (30ml) lemon juice (adds acidity)

How to Make Gluten-Free Lemon Blueberry Bars (Dairy-Free)

Step 1. Begin by preheating your oven to 350°F (175°C). This ensures that your bars will bake evenly once prepared. While the oven warms up, gather all your ingredients and prepare a 9×13-inch baking pan by greasing it lightly or lining it with parchment paper. Doing this will help the bars release easily after baking, resulting in a nice presentation.

Step 2. In a large mixing bowl, combine the granulated sugar and lemon zest. Using a whisk or electric mixer, mix them together until well combined. The goal here is to release the aromatic oils from the lemon zest into the sugar, enhancing the overall flavor of your bars. This fragrant blend sets the stage for the moist and tasty base.

Step 3. Next, add the room-temperature salted butter and vanilla to the sugar mixture. Beat the ingredients together until they form a creamy and smooth consistency. It’s important to ensure the butter is soft enough to blend well; this will create a light texture in the finished bars. Scrape down the sides of the bowl as needed to fully incorporate all ingredients.

Step 4. Gradually stir in the gluten-free flour blend along with the fine sea salt. Use a rubber spatula or wooden spoon to fold the flour into the mixture until fully combined. Watch for any dry clumps of flour as you mix. The dough should form a thick batter. Be careful not to overmix, as this can cause the bars to become dense.

Step 5. Once the batter is ready, gently fold in the blueberries. You want to distribute them evenly throughout the batter without crushing them too much. This process will help maintain the blueberries’ shape and keep your bars beautiful after baking. Aim for an even mixture so that every bite is packed with berries.

Step 6. Pour the batter into your prepared baking pan. Smooth the top with a rubber spatula, ensuring an even layer. This will help the bars bake uniformly. Place the pan in the preheated oven and bake for 30-35 minutes, or until the top is lightly golden and a toothpick inserted in the center comes out clean. Keep an eye on the bars as they bake to prevent over-browning.

Step 7. While the bars bake, prepare the blueberry topping. In a medium bowl, combine ¼ cup granulated sugar, the remaining 2 tablespoons lemon juice, and cornstarch. Stir until everything is well mixed. This topping adds a touch of sweetness and helps create a nice glaze on the baked bars. Set this mixture aside to allow the flavors to meld.

Step 8. Once the bars are done baking, remove them from the oven and immediately pour the blueberry mixture evenly over the top. Use a spatula to spread it into an even layer if needed. Return the bars to the oven for an additional 10-12 minutes. You’re looking for the topping to bubble slightly but not burn.

Step 9. After baking the topping, remove the bars from the oven and let them cool completely in the pan on a wire rack. This cooling period is essential for the bars to set properly. Once they are cool, you can lift them out of the pan using the parchment paper edges. Slice them into squares for serving.

Step 10. Before serving, dust the bars with the powdered sugar and a half tablespoon of lemon juice mixture for a beautiful finish. This step adds a lovely touch of sweetness and a burst of lemony flavor, enhancing the overall experience. Enjoy your lemon blueberry bars as they are, or pair them with a hot cup of tea for a comforting treat.

Pro Tips for Best Results

• Ensure your butter is at room temperature for easier mixing.
• Use a light touch when folding in the blueberries to prevent smashing them.
• Allow the bars to cool completely before cutting them for cleaner slices.
• If using fresh blueberries, consider rinsing and drying them gently to remove extra moisture.
• Keep an eye on the baking time to avoid overbaked, dry bars.
• For a brighter flavor, consider adding extra lemon zest.

Common Mistakes to Avoid

1. Not using room-temperature butter: Cold butter can lead to a lumpy texture that won’t blend properly, affecting the final consistency. Make sure it’s softened to room temperature for a smooth batter.
2. Overmixing the batter: Mixing too vigorously after adding the flour can develop gluten, making the bars dense instead of light. Mix just until combined for the best texture.
3. Underbaking the bars: If you take them out too early, the bars may fall apart or be soggy inside. Keep an eye on them and use a toothpick to check for doneness.
4. Skipping the cooling time: Cutting into the bars too soon can result in crumbs and a messy presentation. Allow them to cool completely in the pan to set properly.
5. Using stale or old blueberries: Fresh blueberries not only taste better but also hold their shape during baking. Check the berries for freshness to ensure optimal flavor and texture.
6. Not adjusting for personal taste: If you prefer a sweeter or more tart bar, adjusting the sugar or lemon juice can enhance the flavors to match your preference. Don’t hesitate to make it your own.

Variations & Substitutions

Consider adding a sprinkle of nuts like slivered almonds for a crunch factor. You may also substitute the blueberries with raspberries or strawberries for a different fruit twist. For a touch more sweetness or acidity, try adding a little extra lemon juice or zest to the base or topping. Enjoy experimenting with flavors that you love.

Storage & Reheating

For short-term storage, keep the bars in an airtight container at room temperature for 1-2 days. If you want to store them longer, place them in the refrigerator, where they can last up to a week. For freezing, wrap the cooled bars tightly in plastic wrap or place them in a freezer-safe container for up to three months. When ready to enjoy, thaw them at room temperature, or gently reheat them in the oven at a low temperature to preserve the texture.
