Step-by-Step Instructions
Creating these beautiful Lemon Crumb Bars is a straightforward process. Follow these detailed steps to achieve perfect results every time. Remember, precise measurements and gentle handling contribute to their fantastic texture and flavor.
1. Prepare Your Baking Pan: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on the sides.
This makes removing the Lemon Crumb Bars much easier later. Lightly grease the parchment paper.
2. Make the Crumb Mixture: In a large bowl, whisk together the flour, granulated sugar, baking powder, and salt. Add the cold, cubed butter and vanilla extract. Use a pastry blender, your fingertips, or a food processor to cut the butter into the dry ingredients.
You want a mixture resembling coarse crumbs, with some pea-sized pieces of butter remaining.
3. Form the Crust: Press about two-thirds of the crumb mixture firmly and evenly into the bottom of the prepared baking pan.
This forms the delicious base for your Lemon Crumb Bars. Reserve the remaining one-third of the crumb mixture for the topping.
4. Partially Bake the Crust: Bake the crust in the preheated oven for 15-18 minutes, or until it is lightly golden brown around the edges. This initial bake prevents a soggy bottom.
5.
Prepare the Lemon Filling: While the crust bakes, whisk together the granulated sugar, flour, baking powder, and salt in a medium bowl. In a separate bowl, whisk the eggs, fresh lemon juice, and lemon zest until well combined. Gradually add the wet ingredients to the dry ingredients, whisking until smooth.
Do not overmix.
6. Assemble the Lemon Crumb Bars: Carefully pour the lemon filling evenly over the partially baked crust.
7. Add the Topping: Crumble the reserved one-third of the crumb mixture evenly over the lemon filling.
8. Bake the Bars: Return the pan to the oven and bake for an additional 25-30 minutes, or until the topping is golden brown and the lemon filling is set. A slight jiggle in the center is okay, as it will continue to set as it cools.
9. Cool Completely: Remove the Lemon Crumb Bars from the oven and place the pan on a wire rack to cool completely. This is a crucial step! The filling needs to set fully.
This can take 2-3 hours.
10. Slice and Serve: Once completely cool, use the parchment paper overhang to lift the bars out of the pan.
Dust with powdered sugar, if desired, then slice into squares or rectangles. Enjoy your homemade Lemon Crumb Bars!
Pro Tips for Success
Achieving perfect Lemon Crumb Bars involves a few key techniques. These Lena-approved tips ensure your bars turn out beautifully every time.
* Cold Butter is Key: Always use very cold, cubed butter for the crumb mixture. This prevents the butter from melting too quickly during mixing and creates a tender, flaky crust and topping. Cold butter also produces those desirable crumbly bits.
* Don’t Overmix the Crumb: When combining the butter with the dry ingredients, mix just until coarse crumbs form. Overmixing develops the gluten in the flour too much, leading to a tough crust.
* Press Firmly for the Crust: Ensure you press the crust mixture firmly and evenly into the pan.
A solid, compact crust holds the filling beautifully.
* Fresh Lemon Juice and Zest: Do not use bottled lemon juice for these Lemon Crumb Bars. Freshly squeezed lemon juice and freshly grated zest provide the brightest, most authentic lemon flavor.
Zest before juicing for easier handling.
* Avoid Overbaking the Filling: Watch the bars closely during the final bake. The filling should be set but still have a slight jiggle in the center.
Overbaking can result in a rubbery texture.
* Cool Completely: This tip cannot be stressed enough! The lemon filling needs ample time to cool and set properly.
Slicing warm Lemon Crumb Bars will result in a messy, gooey disaster. Patience truly pays off here.
* Dust with Powdered Sugar Just Before Serving: For the freshest appearance, dust your cooled Lemon Crumb Bars with powdered sugar right before you plan to serve them. The sugar can absorb moisture and disappear if applied too early.

Storage & Reheating Tips
Keeping your Lemon Crumb Bars fresh is easy with these simple storage guidelines. You can enjoy their bright, zesty flavor for days after baking.
* Countertop Storage: Store fully cooled Lemon Crumb Bars in an airtight container at room temperature for up to 2 days. For optimal freshness, separate layers with parchment paper if stacking.
* Refrigeration: For longer storage, refrigerate the Lemon Crumb Bars in an airtight container for up to 5-7 days.
The cooler temperature helps maintain the filling’s texture and prolongs shelf life. Let them come to room temperature for about 15-20 minutes before serving for the best flavor and texture.
* Freezing: Yes, you can freeze Lemon Crumb Bars!
Place cooled and sliced bars in a single layer on a baking sheet and freeze until solid (about 2 hours). Then, transfer them to a freezer-safe airtight container or freezer bag, separating layers with parchment paper. Freeze for up to 2-3 months.
* Thawing: Thaw frozen Lemon Crumb Bars in the refrigerator overnight or at room temperature for a few hours. Do not reheat in the microwave, as it can make the crumb topping soft and soggy. Enjoy them chilled or at room temperature.

FAQs
Here are answers to some common questions about making and enjoying these wonderful Lemon Crumb Bars.
Can I make the lemon filling ahead of time?
While you can prepare the lemon filling mixture a few hours in advance, it’s generally best to assemble and bake the Lemon Crumb Bars immediately after making the filling. The flour in the filling acts as a thickener, and sitting too long might affect its consistency. For the freshest taste and best texture, prepare the filling just before pouring it over the baked crust.
Why did my Lemon Crumb Bars turn out runny?
Several factors can cause runny Lemon Crumb Bars. Most commonly, it’s either underbaking or not allowing the bars to cool completely. Ensure you bake the bars until the filling is set with only a slight jiggle in the center.
The most crucial step is to let them cool completely, preferably for several hours or even overnight, before slicing. The filling continues to set as it cools.
Can I use bottled lemon juice?
For the absolute best flavor in your Lemon Crumb Bars, use fresh lemon juice and zest. Bottled lemon juice often contains preservatives and lacks the vibrant, natural acidity and aroma of fresh lemons. The difference in taste is significant and truly worth the extra effort.
My crumb topping isn’t crumbly enough, what happened?
If your crumb topping isn’t as crumbly as you’d like, you might have overmixed the ingredients, causing the butter to fully incorporate. The key to a good crumb is to stop mixing when the butter is still in pea-sized pieces, creating those lovely pockets of butter that crisp up during baking. Also, ensure your butter is very cold to begin with.
How many lemons do I need for this recipe?
You will typically need about 3-4 medium-sized lemons to yield the ¾ cup of fresh lemon juice required for the filling. Additionally, you will need approximately 2 lemons for the 2 tablespoons of lemon zest. Always have an extra lemon on hand, just in case! These Lemon Crumb Bars truly benefit from ample lemon flavor.
Lemon Crumb Bars are a popular dessert that combines a buttery crust, tangy lemon filling, and a crumbly topping, making them a delightful treat. For more insights into this refreshing dessert, explore its origins in lemon varieties.
