How to prepare Lemon Crumb Bars:
Creating delightful Lemon Crumb Bars is straightforward. Follow these clear steps to enjoy a tangy and sweet treat!
Step 1: Gather Ingredients
Start by collecting all the necessary ingredients for your Lemon Crumb Bars. You will need all-purpose flour, granulated sugar, unsalted butter, eggs, fresh lemon juice, lemon zest, baking powder, and salt. Measure each item accurately for the best results.
Step 2: Preheat the Oven
Next, preheat your oven to 350°F (175°C). Ensuring your oven is at the right temperature allows for even baking.
Step 3: Prepare the Baking Dish
Line a 9×9 inch baking dish with parchment paper. Leave some overhang for easy removal later. You can also grease the dish with butter or cooking spray for an extra non-stick layer.
Step 4: Make the Crust
In a large mixing bowl, combine 1 cup of all-purpose flour, ½ cup of granulated sugar, and ½ cup of melted unsalted butter. Stir these ingredients until they form a crumbly mixture.
Step 5: Press the Mixture into the Dish
Take the crumbly mixture and press it firmly into the prepared baking dish. This serves as the base for your bars and should be evenly spread to cover the bottom.
Step 6: Bake the Crust
Bake the crust in the preheated oven for 15-20 minutes. It should turn a light golden brown color before removing it from the oven.
Step 7: Prepare the Lemon Filling
While the crust bakes, whisk together 1 cup of granulated sugar, 2 large eggs, ¼ cup of fresh lemon juice, the zest of 1 lemon, 1 tablespoon of all-purpose flour, and ¼ teaspoon of baking powder in a bowl until smooth.
Step 8: Pour the Filling
After the crust has finished baking, remove it from the oven and pour the lemon filling evenly over the hot crust. This creates a lovely layer of tangy goodness on top.
Step 9: Bake Again
Return the baking dish to the oven and bake for an additional 20-25 minutes. The filling should set and become slightly firm.
Step 10: Cool and Cut the Bars
Once done, allow the Lemon Crumb Bars to cool completely in the dish on a wire rack. After cooling, use the parchment overhang to lift the bars out, and cut them into squares. Enjoy!

Tips for the Perfect Lemon Crumb Bars
Maintain the Right Temperature
When baking lemon crumb bars, it is vital to keep your ingredients at the correct temperature. For the butter, ensure it is softened but still slightly cool to the touch. This helps create the perfect crumbly texture. Similarly, when preparing the lemon filling, use room temperature eggs, as they mix more evenly and produce a smoother batter. If you just take them out of the fridge, consider placing them in warm water for 10-12 minutes before using.
Use Quality Ingredients
Quality matters when it comes to your lemon crumb bars. Opt for fresh lemons instead of bottled lemon juice for the best flavor. The zest adds a vibrant citrus note that can elevate your dessert. Choose high-quality butter and organic flour to enhance the taste and texture of your bars. If you’re feeling adventurous, consider adding a touch of vanilla extract to both the crumb base and the filling for an extra layer of flavor.
Dietary Substitutions
To accommodate dietary needs, there are various substitutes to consider. For a gluten-free option, replace regular flour with a gluten-free blend. Make sure to select one designed for baking to ensure proper texture. If dairy is a concern, coconut oil can replace butter; just melt it before mixing it into the crumb base. For a vegan variation, use flax eggs: mix one tablespoon of ground flaxseed with three tablespoons of water for each egg. Let it sit for about 5 minutes before adding it to your batter.
Perfecting the Crust
The crust is crucial for texture. When mixing your crumb base, don’t overwork the dough; it should resemble wet sand. Pack it only firmly enough in the pan to create a solid foundation. If you prefer a thicker crust, increase the crust ingredients by a third. For additional flavor, experiment by adding a pinch of salt or a dash of cinnamon to the crumb mixture.
Chill for Best Results
After baking, allow your dessert to cool at room temperature before chilling in the refrigerator. This will help the filling set properly, making it easier to cut clean squares. For serving, dust a light layer of powdered sugar on top for a pretty presentation. Enjoy your homemade bars with family and friends, knowing you’ve perfectly balanced flavor and texture with these simple tips!
Storage Tips for Lemon Crumb Bars:
Proper storage of your delicious treats is essential to keep them fresh and tasty. Follow these tips to maintain the quality of your lemon crumb bars for as long as possible.
Cool Before Storing
Always allow your lemon crumb bars to cool completely after baking. Storing them while still warm can create condensation, making the bars soggy. Once cooled, you can prepare them for storage.
Use an Airtight Container
To maximize freshness, place your lemon crumb bars in an airtight container. This prevents exposure to air, which can dry out the bars or lead to staleness. If possible, choose a container that fits the bars snugly to reduce airspace.
Layer Wisely
If you stack the bars in the container, use parchment paper between the layers. This method prevents sticking and maintains the crumbly texture of the bars. Avoiding direct contact between the bars also helps preserve their flavor.
Refrigerate for Extended Freshness
For longer shelf life, store your lemon crumb bars in the refrigerator. They typically last about one week when refrigerated. Ensure the container is sealed well to avoid absorbing other odors from the fridge.
Freezing for Longer Storage
If you want to keep the bars for an extended period, consider freezing them. Wrap each bar tightly in plastic wrap and then place them in a freezer-safe bag or container. Frozen lemon crumb bars can last up to three months. Label the container with the date for easy reference.
Thawing and Enjoying
When you are ready to enjoy the frozen bars, transfer them to the refrigerator to thaw overnight. For a quicker option, you can leave them at room temperature for about an hour. This method keeps the texture intact while restoring their delicious flavor.
Check Before Serving
Always inspect the bars before serving, especially if they have been stored for a while. Look for any signs of spoilage, such as off odors or unusual textures. If they look and smell good, they should be fine to enjoy!
By following these straightforward storage tips, you can savor your lemon crumb bars at their best. The proper environment ensures that every bite remains as fresh and delightful as the day they were made!
