How to Make Lemon Crumb Bars
Follow these simple steps to prepare this delicious dish:
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). Prepare an 8×8-inch baking dish by greasing it with nonstick spray or lining it with parchment paper.
Step 2: Prepare the Crust
In a mixing bowl, combine flour, sugar, and softened butter until crumbly. Press this mixture into the bottom of your prepared baking dish evenly.
Step 3: Bake the Crust
Place the baking dish in the preheated oven and bake for about 15 minutes or until lightly golden brown.
Step 4: Make the Filling
In another bowl, whisk together granulated sugar, flour, lemon zest, lemon juice, and eggs until smooth. Pour this mixture over the baked crust.
Step 5: Add Topping
Sprinkle any remaining crumb mixture over the top of the lemon filling carefully.
Step 6: Bake Again
Return to oven and bake for an additional 20-25 minutes until set. Allow cooling completely before slicing into squares.
Transfer to plates and serve chilled or at room temperature for the perfect finishing touch.
Tips and Tricks
Here are some helpful tips to ensure the best results for your dish:
- Use Fresh Ingredients: Fresh lemons provide brighter flavors compared to bottled juices; always opt for fresh whenever possible.
- Let Them Cool Completely: Allowing your Lemon Crumb Bars to cool completely before slicing helps achieve clean cuts and better presentation.
- Store Properly: Keep leftover bars covered in an airtight container in the refrigerator for up to five days; enjoy them chilled!
Mistakes to avoid
- Using the Wrong Type of Lemons: One common mistake is using lemons that are not fresh or ripe. Always choose juicy, vibrant lemons for your Lemon Crumb Bars. The zest and juice from fresh lemons provide the essential tangy flavor that makes these bars irresistible. Avoid using bottled lemon juice, as it lacks the brightness and depth of flavor that fresh lemons offer. Take a moment to squeeze your lemons and zest them before starting your recipe; this will significantly enhance the taste of your bars.
- Overbaking the Crust: A major pitfall when making Lemon Crumb Bars is overbaking the crust. The crust should be golden brown but not too dark. If you bake it too long, it can become hard instead of crumbly. Keep an eye on it during baking and set a timer. Once you notice a light golden color, remove it from the oven immediately to maintain that perfect crumbly texture.
- Skipping the Chilling Time: Many people rush the process by skipping the chilling time after baking their Lemon Crumb Bars. Allowing them to cool completely in the refrigerator enhances their texture and flavor development. Chilling helps firm up the bars, making them easier to cut into neat squares or rectangles. Patience is key here; waiting for at least an hour will reward you with deliciously structured bars.

FAQs about Lemon Crumb Bars:
What ingredients are needed for Lemon Crumb Bars?
To make delicious Lemon Crumb Bars, you will need all-purpose flour, granulated sugar, powdered sugar, unsalted butter, eggs, lemon juice, lemon zest, and baking powder. These simple ingredients come together to create a delightful treat with a crumbly base and a bright lemon filling. The combination of these components ensures that each bite is bursting with flavor while maintaining a tender texture. You can also add a pinch of salt to enhance the overall taste.

How long do Lemon Crumb Bars last?
Lemon Crumb Bars can last for about four to five days when stored properly. To keep them fresh, store them in an airtight container at room temperature for the first couple of days.

With this substitution, you can still achieve those delightful flavors without sacrificing quality or taste.
