How to Make Lemon Crumb Bars
Step 1: Prepare the Crust
Preheat your oven to 350°F (175°C). In a large bowl, mix together the flour, sugar, baking powder, melted butter, and salt until crumbly. This mixture will create a delicious base for our bars. Remember to reserve 1/2 cup of this mixture for topping later! Press the remaining mixture firmly into the bottom of an 8×8-inch baking pan lined with parchment paper. Bake this crust for about 12-15 minutes until it’s lightly golden.
Step 2: Make the Filling
In another bowl, whisk together the eggs, sugar, flour, lemon juice, and lemon zest until smooth. This is where the magic happens! The combination creates that lovely tart filling that pairs so well with the buttery crust. Take your time mixing; you want it nice and smooth!
Step 3: Combine Layers
Once your crust has baked and cooled slightly, pour the lemon mixture evenly over it. Then sprinkle that reserved crumb mixture on top. This layer adds a delightful crunch that contrasts beautifully with the creamy filling underneath.
Step 4: Final Bake
Return your pan to the oven and bake for an additional 20-25 minutes or until the filling is set and the top is lightly golden. Keep an eye on it; you want those edges just slightly crisp while keeping that lovely soft center.
Step 5: Chill & Serve
Let the bars cool completely at room temperature before chilling them in the refrigerator for at least an hour. Once chilled, slice them into squares and dust with powdered sugar before serving. They’re best enjoyed chilled — perfect for hot days or whenever you’re craving something refreshing!

Pro Tips for Making Lemon Crumb Bars
Making lemon crumb bars can be a breeze if you follow these helpful tips. They will help ensure your bars turn out perfectly every time!
-
Use Fresh Lemons: Fresh lemon juice and zest provide vibrant flavor that bottled alternatives can’t match, making your bars taste bright and zesty.
-
Chill Before Cutting: Allowing the bars to chill in the refrigerator for at least an hour after baking helps them set properly, making them easier to cut into neat squares.
-
Don’t Overbake: Keep an eye on the baking time; overbaking can lead to a dry filling. The filling should be just set but still slightly jiggly in the center when you take it out of the oven.
-
Line Your Pan: Using parchment paper to line your baking pan not only makes cleanup easier but also ensures your bars come out without sticking.
-
Experiment with Flavors: While lemon is delightful on its own, consider adding a hint of lime or orange zest for a fun twist that can brighten up the flavor profile!
How to Serve Lemon Crumb Bars
Presenting your lemon crumb bars beautifully can enhance the enjoyment of this delicious treat. Here are some ideas for serving them up in style:
Garnishes
- Powdered Sugar: A light dusting of powdered sugar adds a touch of sweetness and makes your bars look extra inviting.
- Fresh Berries: Garnishing with fresh blueberries or raspberries not only adds color but also complements the tangy lemon flavor beautifully.
Side Dishes
-
Vanilla Coconut Whipped Cream: A dollop of fluffy whipped cream made with coconut cream adds a creamy richness that balances the tartness of the bars.
-
Fruit Salad: A refreshing fruit salad featuring seasonal fruits provides a light and healthy contrast to the richness of the crumb bars.
-
Herbal Iced Tea: Pairing your dessert with a chilled herbal iced tea can enhance the experience, offering a refreshing sip that complements the citrus notes.
-
Sorbet: A scoop of lemon or berry sorbet serves as a delightful palate cleanser, making it perfect for summer gatherings or any occasion where you want something refreshing!

FAQs
Here are some common questions you might have about making Lemon Crumb Bars.
Can I use bottled lemon juice instead of fresh?
While fresh lemon juice is recommended for its vibrant flavor, bottled lemon juice can be used in a pinch. Just ensure it’s 100% lemon juice without additives.
How can I make my Lemon Crumb Bars sweeter?
If you prefer a sweeter taste, consider adding more sugar to the lemon filling or dusting with powdered sugar before serving. Adjust according to your personal preference!
What can I do if my filling is too runny?
If the filling seems too runny after baking, it may need more time in the oven. Bake it a bit longer until it sets properly. Remember, cooling will also help it firm up.

Adding extra lemon zest or even a hint of vanilla extract can elevate these bars’ flavor. Experiment with these additions until you find your perfect balance!
