For the Crust

Granulated Sugar – Sweetens the crust beautifully.
Light Brown Sugar – Adds moisture and a hint of caramel flavor to elevate the crust.
Salt – Enhances the overall flavors for a balanced taste.
Baking Powder – Helps the crust rise slightly during baking for a perfect texture.
Unsalted Butter – Creates a rich, buttery flavor; remember to melt and cool before use!

For the Filling

Sweetened Condensed Milk – Adds creaminess and sweetness to the lemon filling.
Egg Yolks – Provide rich structure to the filling; make sure they’re at room temperature for optimum blending.

Step‑by‑Step Instructions for Lemon Crumb Bars

Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, line a 9×9-inch baking pan with parchment paper, allowing some overhang for easy removal later. This step ensures that your Lemon Crumb Bars come out beautifully and are easy to cut after chilling.

Step 2: Prepare Crust
In a mixing bowl, combine all-purpose flour, granulated sugar, light brown sugar, salt, and baking powder. Pour in the melted and cooled unsalted butter, mixing until the mixture is crumbly but holds together when pressed. Firmly press about two-thirds of this mixture into the prepared pan to create a solid crust. Bake for 15 minutes, or until lightly golden and fragrant.

Step 3: Make Filling
While the crust is baking, prepare the creamy filling for your Lemon Crumb Bars. In a separate bowl, whisk together the sweetened condensed milk, egg yolks (ensuring they are at room temperature), heavy cream, and a pinch of salt until the mixture is smooth and well combined. Gradually add in the freshly squeezed lemon juice, whisking until fully incorporated for that zesty flavor.

Step 4: Assemble Bars
Once the crust is baked and slightly cooled, pour the luscious lemon filling over the warm crust, smoothing it evenly with a spatula. Sprinkle the remaining crumb mixture on top of the filling, ensuring it covers it well. Place the assembled bars back into the oven and bake for an additional 15-20 minutes. You’ll know they are done when the top is golden brown and the filling is set but slightly jiggles in the center.

Step 5: Cool and Chill
After baking, remove your Lemon Crumb Bars from the oven and allow them to cool at room temperature for about 20-30 minutes. Once cooled slightly, transfer them to the refrigerator and let them chill for at least 4 hours. This is crucial for achieving clean and beautiful slices, enhancing both the flavor and texture of these delicious bars.

Expert Tips for Lemon Crumb Bars

Chill Properly: Refrigerating for at least four hours is vital; cutting too soon can lead to messy, uneven slices that crumble.
Fresh Juice Matters: Using fresh lemon juice creates a vibrant flavor; bottled varieties may impart a bitter taste that dampens the dish’s appeal.
Watch the Bake: Ensure the filling is set but slightly jiggly when you take it out; overbaking dries the filling, ruining those delicious Lemon Crumb Bars.
Use Parchment Wisely: Leave an overhang of parchment paper for easy removal and slicing; this simple tip takes the stress out of serving.
Press Firmly: Compact the crust mixture well into the pan to prevent it from crumbling when sliced; a solid base makes all the difference in presentation.

How to Store and Freeze Lemon Crumb Bars

Fridge: Keep your Lemon Crumb Bars in an airtight container in the refrigerator for up to 5 days to maintain their freshness.

Freezer: For longer storage, freeze the bars wrapped securely in plastic wrap, then placed in an airtight container for up to 3 months.

Thawing: To enjoy frozen Lemon Crumb Bars, thaw them in the fridge overnight before serving to ensure they retain their delicious texture.

Reheating: If you prefer them slightly warm, you can reheat individual bars in the microwave for 10-15 seconds; just be careful not to overheat!

Make Ahead Options

These Lemon Crumb Bars are perfect for busy home cooks looking to simplify meal planning! You can prepare the crust and filling up to 24 hours in advance, ensuring all the flavors meld beautifully. To do this, bake the crust and let it cool completely before wrapping it tightly in plastic wrap or storing it in an airtight container. The lemon filling can also be mixed in advance and refrigerated in a separate container. When you’re ready to serve, simply pour the chilled filling over the crust, sprinkle the crumb topping, and bake as directed. Chilling before serving helps the bars maintain their richness and texture, allowing you to enjoy delicious dessert with minimal effort!

What should I do if my filling is too runny?
If you find that your filling is too runny, it may be due to underbaking or not using enough egg yolks. Make sure to bake the bars until the filling is set but still slightly jiggly in the center.
