Step‑by‑Step Instructions for Lemon Crumb Bars
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). While it heats, prepare your 9×9-inch baking pan by lining it with parchment paper, allowing some overhang for easy removal later. This setup ensures your Lemon Crumb Bars bake evenly and lift out effortlessly.
Step 2: Make the Crust
In a large mixing bowl, combine all-purpose flour, granulated sugar, light brown sugar, salt, and baking powder. Pour in the melted and cooled unsalted butter, stirring until the mixture has a crumbly texture. This crust will provide the foundation for your Lemon Crumb Bars, giving them that irresistible buttery flavor.
Step 3: Press Crust into Pan
Take about two-thirds of the crumb mixture and evenly press it into the bottom of your prepared baking pan. Make sure to pack it down well to create a solid base. Bake in the preheated oven for 15 minutes or until the crust is lightly golden and fragrant, which will provide a delightful crunch.
Step 4: Prepare the Filling
While the crust is baking, whisk together the sweetened condensed milk, egg yolks, heavy cream, and salt in a separate bowl until smooth and well combined. Gradually add the fresh lemon juice, continuing to whisk until everything is fully incorporated. This mixture becomes the luscious filling of your Lemon Crumb Bars.
Step 5: Assemble the Bars
Once the crust is done, carefully pour the lemon filling over the hot crust in the pan. Next, sprinkle the remaining crumb mixture on top of the filling to create an enticing texture. Return the pan to the oven and bake for an additional 15-20 minutes, until the top is golden, and the filling is set—slightly soft in the center is ideal.
Step 6: Cool and Chill
After baking, allow the bars to cool at room temperature for about 30 minutes. Then, transfer them to the refrigerator and chill for at least 4 hours. This cooling time is crucial for the filling to firm up, ensuring your Lemon Crumb Bars can be sliced beautifully and hold their shape when served.
