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). Grease an 8×8-inch baking dish with nonstick spray or line it with parchment paper.

Place the crust in your preheated oven and bake it for about 15 minutes or until lightly golden.
Step 4: Make the Filling
In another bowl, whisk together eggs, granulated sugar, lemon juice, lemon zest, flour, and baking powder until well combined. Pour this mixture over your pre-baked crust.
Step 5: Bake Again
Return the baking dish to the oven and bake for an additional 20-25 minutes or until set and lightly golden on top.

Tips and Tricks
Here are some helpful tips to ensure the best results for your dish:
- Use Fresh Lemons: Freshly squeezed lemon juice provides optimal flavor compared to bottled alternatives.
- Let Them Cool Completely: Cooling allows the filling to set properly before cutting into bars.
- Add Zest for Extra Flavor: Incorporate extra lemon zest into both crust and filling for heightened citrus flavor.
Mistakes to avoid
- Not Using Fresh Lemons
When making Lemon Crumb Bars, using fresh lemons is crucial for achieving that vibrant, zesty flavor. Bottled lemon juice often lacks the brightness and acidity of fresh juice. This can result in a dull taste that doesn’t do justice to the dessert. Always opt for freshly squeezed juice and zest from organic lemons. This small change will elevate your bars, giving them a refreshing citrus punch that makes your dessert memorable.
- Overbaking the Crust
Many bakers make the mistake of overbaking the crust while preparing Lemon Crumb Bars. The crust should be lightly golden but not too dark. Overbaking can lead to a dry and crumbly texture, which can overshadow the creamy lemon filling. Keep an eye on your crust as it bakes, and remember that it will continue to cook slightly after being removed from the oven. Taking it out at just the right moment ensures a perfect balance of textures.
- Skipping the Chilling Time
A common oversight when making Lemon Crumb Bars is skipping the chilling time after baking. Allowing the bars to cool completely before cutting is essential for achieving clean edges and ensuring they hold their shape. If you cut them too soon, they may crumble or become messy, compromising their visual appeal and texture. Be patient; chilling not only improves presentation but also enhances flavors as they meld together beautifully.
Serving Suggestions
This Lemon Crumb Bars is versatile and pairs wonderfully with:
- Fresh Berries: Serve your Lemon Crumb Bars with a side of fresh strawberries, blueberries, or raspberries. The tartness of the berries complements the sweet and tangy flavors of the bars.
- Whipped Cream: A dollop of homemade whipped cream adds a creamy texture that balances the bright lemon flavor in each bite. Consider adding a hint of vanilla for an extra layer of flavor.
- Iced Tea: Pairing your Lemon Crumb Bars with a refreshing glass of iced tea makes for a delightful afternoon treat. Opt for sweetened or unsweetened tea based on your preference.
