For the Crust and Crumble:

All-purpose flour: The foundation of our buttery crust and crumble. Makes sure it’s fresh for the best texture.
Granulated sugar: Adds sweetness and helps create that perfect golden color during baking.
Brown sugar: Provides a touch of molasses flavor, deepening the taste of the crumb topping.
Cold unsalted butter: The key to a flaky, crumbly texture. Make sure it's cold – this is crucial!

For the Lemon Filling:

Granulated sugar: Sweetens the tartness of the lemon juice, balancing the flavors beautifully.
Cornstarch: Thickens the filling, giving it a smooth and creamy consistency. Don't skip this!
Eggs: Binds the filling together and contributes to its richness.
Lemon juice: The star of the show! Freshly squeezed lemon juice is best for the most vibrant flavor.
Lemon zest: Adds an extra layer of lemon flavor and a lovely aroma. This is a must!

Step-by-Step Instructions

Alright, let's get into the fun part: making these amazing lemon crumb bars! Follow these steps closely, and you'll be well on your way to dessert heaven. I've broken it down so that it's super easy to follow, even if you are a newbie in the kitchen.

Making the Crust and Crumble

Prep the oven and pan: Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking pan. Line the bottom of the pan with parchment paper, leaving an overhang on the sides for easy removal of the bars later. This will make your life so much easier when it comes to cutting and serving.
Combine dry ingredients: In a large bowl, whisk together the flour and granulated sugar, and brown sugar. This ensures everything is evenly distributed.
Cut in the butter: Add the cold, cubed butter to the dry ingredients. Using a pastry blender, a fork, or your fingertips, cut the butter into the flour until the mixture resembles coarse crumbs. This step is super important for achieving that perfect crumbly texture. The butter needs to be evenly incorporated to ensure the bars are perfection.
Press into the pan: Press half of the crumb mixture firmly into the prepared baking pan. This will be the base of your bars. Make sure it's evenly distributed for a nice, consistent layer. This is going to be the foundation of your amazing bars!
Freeze the remaining crumbs: Place the remaining crumb mixture in the freezer while you prepare the lemon filling. This helps to keep the crumbs cold, which results in a better crumble topping. This is a pro-tip for optimal crumb topping goodness!

Preparing the Lemon Filling

Whisk the filling ingredients: In a separate bowl, whisk together the granulated sugar, cornstarch, and eggs until smooth. Make sure there are no lumps in the cornstarch. No one likes a lumpy filling. Gross!
Add the lemon juice and zest: Stir in the fresh lemon juice and lemon zest. This is where all the wonderful lemon flavor comes from, so don't skimp on the zest.
Pour over the crust: Pour the lemon filling evenly over the crust in the baking pan. Make sure that the filling is evenly distributed across the base.

Assembling and Baking

Sprinkle the crumble topping: Take the crumb mixture from the freezer and sprinkle it evenly over the lemon filling. Make sure that the crumble topping covers the entire surface of the lemon filling. This is what will give the bars their amazing texture and visual appeal.
Bake: Bake in the preheated oven for 30-35 minutes, or until the topping is golden brown and the filling has set. The edges should be golden, and the center should be set but still have a slight jiggle. Keep an eye on the bars as they bake to prevent over-baking. Over-baking can make the filling dry. No one wants dry bars!
Cool completely: Let the bars cool completely in the pan before cutting. This is essential for the filling to set properly. This will prevent a runny filling and make them easier to cut into clean squares. I know, waiting is the hardest part, but it's worth it, I promise.
Cut and serve: Once cooled, lift the bars out of the pan using the parchment paper overhang. Cut into squares and serve. Enjoy the best lemon crumb bars of your life!

Use fresh lemon juice: Freshly squeezed lemon juice makes a huge difference in the flavor of the filling. Bottled lemon juice can be okay, but fresh is always superior for that vibrant, zesty taste. Seriously, guys, fresh juice is the key to that amazing lemon flavor.
Don't overbake: Overbaking can lead to a dry filling. Keep an eye on the bars during the last few minutes of baking. The edges should be golden brown, and the center should be set but still have a slight jiggle. This helps keep the filling moist and delicious.
Cool completely: Allow the bars to cool completely before cutting. This will allow the filling to set properly and make it easier to cut into clean squares. Patience, my friends, patience! It's worth the wait, I promise.
Chill before serving: For an extra refreshing treat, chill the bars in the refrigerator for a couple of hours before serving. This enhances the flavors and provides a delightful, cold dessert experience. This is especially good on a hot day!
Use good quality butter: The quality of the butter impacts the flavor and texture of the crust and crumble. Use unsalted butter and make sure it’s cold. Quality butter is like the foundation of a good house; it determines the deliciousness of the overall creation.

Troubleshooting Common Issues

Sometimes, things don’t always go according to plan, and that's okay! Here are some common issues you might encounter while making lemon crumb bars, and how to fix them:

Crust is too crumbly: If the crust is too crumbly and doesn't hold together, you might not have packed it tightly enough into the pan. Make sure you press it down firmly. You can also add a tablespoon or two of cold water to the crumb mixture before pressing it into the pan.
Filling is too runny: If the filling is too runny after baking, you might not have used enough cornstarch. Make sure to measure the cornstarch accurately. Also, ensure the bars have cooled completely before cutting into them.
Crumble is not golden brown: If the crumble topping isn't browning, your oven temperature might be too low. Check the temperature of your oven with an oven thermometer and adjust if necessary. You can also try broiling the bars for a minute or two at the end of the baking time, but keep a close eye on them to prevent burning. Remember, a golden-brown crumble is a sign of a perfect bake!
Bars are sticking to the pan: Make sure you grease the pan thoroughly and use parchment paper. The parchment paper will help you lift the bars out of the pan easily and prevent them from sticking.
