Ingredients:

• All-purpose flour
• Granulated sugar
• Baking powder
• Salt
• Unsalted butter, chilled and cubed
• Large eggs
• Fresh lemon juice
• Lemon zest
• Sweetened condensed milk

Instructions:

1. Prepare the Crust and Crumble: In a large mixing bowl, combine all-purpose flour, granulated sugar, baking powder, and salt. Cut in the chilled, cubed unsalted butter until the mixture resembles coarse crumbs. Add the large eggs and mix until just combined.
2. Form the Base Layer: Press half of the crumb mixture firmly into the bottom of a greased 9×13-inch baking dish to form an even layer.
3. Create the Lemon Filling: In a separate bowl, whisk together fresh lemon juice, lemon zest, and sweetened condensed milk until smooth and well combined.
4. Assemble the Bars: Pour the lemon filling over the base layer in the baking dish, spreading it evenly. Sprinkle the remaining crumb mixture over the top of the lemon filling to create the crumble topping.
5. Bake to Perfection: Preheat your oven to 350°F (175°C). Bake the assembled bars for 25–30 minutes, or until the top is lightly golden and the filling is set.
6. Cool and Serve: Remove the baking dish from the oven and allow the bars to cool completely on a wire rack. Once cooled, cut into squares and serve.

Secrets to Making the Best Lemon Crumble Bars

1. Use Fresh Lemon Juice and Zest

For the best flavor, always use freshly squeezed lemon juice and lemon zest. Bottled lemon juice lacks the vibrancy and aroma that fresh lemons bring to the filling.

2. Keep the Butter Cold for the Crumble

For a perfectly crumbly topping, make sure to use cold butter when mixing the crumble dough. This creates a light, flaky texture rather than a dense topping.

3. Let the Bars Cool Completely

Resist the urge to slice into the bars too soon! Allow them to cool completely before cutting, as this helps the lemon filling set properly and prevents the bars from falling apart.

4. Adjust the Sweetness to Your Liking

If you prefer a more tart lemon bar, reduce the sugar slightly. For a sweeter version, add an extra tablespoon of sugar to the filling.

5. Dust with Powdered Sugar for a Bakery-Style Look

A light dusting of powdered sugar right before serving adds a beautiful finishing touch and enhances the presentation.

Fun Variations to Try

1. Lemon Blueberry Crumble Bars

Add fresh or frozen blueberries to the lemon filling for a burst of berry flavor and extra juiciness.

2. Coconut Lemon Bars

Mix shredded coconut into the crumble topping for a tropical twist that complements the citrus notes.

3. Raspberry Lemon Bars

Swirl raspberry preserves into the lemon filling before baking for a sweet and tangy contrast.

4. Honey Lemon Bars

Replace some of the sugar with honey to create a richer, more complex sweetness that pairs beautifully with lemon.

5. Gluten-Free Lemon Bars

Swap the all-purpose flour for almond flour or a gluten-free flour blend, making these bars completely gluten-free without sacrificing texture or flavor.

How to Serve Lemon Crumble Bars

1. With a Hot Cup of Tea or Coffee

Pairing these bars with a warm drink enhances their bright citrus flavor and makes for a comforting treat.

2. With a Scoop of Vanilla Ice Cream

For an extra indulgent dessert, serve warm lemon bars with a scoop of vanilla or coconut ice cream.

3. With Whipped Cream and Fresh Berries

A dollop of freshly whipped cream and a handful of strawberries or raspberries make these bars even more visually stunning.

4. Chilled for a Refreshing Treat

Enjoy these bars straight from the fridge on a hot day for a cool, refreshing dessert.

How to Store & Keep Fresh

Refrigeration:

• Store the bars in an airtight container in the refrigerator for up to 5 days.
• This helps maintain their firm texture and enhances the lemon flavor over time.

Freezing:

• Wrap individual bars in plastic wrap and place them in an airtight container.
• Freeze for up to 3 months and thaw in the refrigerator overnight before serving.

Reheating:

• If you prefer to eat them warm, microwave a bar for 10-15 seconds before serving.

Frequently Asked Questions

1. Can I Use Bottled Lemon Juice Instead of Fresh?

Fresh lemon juice is always recommended for the best flavor, but in a pinch, you can use bottled lemon juice. However, the bars will lack the fresh citrus aroma that zest provides.

2. How Do I Prevent My Crumble Topping from Getting Too Hard?

Make sure you don’t overbake the bars. The top should be lightly golden, not overly browned.

3. Can I Make These Bars Dairy-Free?

Yes! Substitute the butter with dairy-free butter or coconut oil and use a dairy-free sweetened condensed milk alternative.

4. Why Did My Bars Turn Out Too Soft?

If the bars seem too soft, they may not have baked long enough or cooled completely before slicing. Make sure they are fully set before cutting.

5. Can I Make These Bars in Advance?

Yes! They taste even better the next day as the flavors develop. Simply store them in the fridge until you’re ready to serve.

6. What’s the Best Way to Cut Perfect Bars?

• Use a sharp knife and wipe it clean between cuts to get sharp, even squares.
• Chilling the bars in the refrigerator before slicing makes cutting easier and neater.
