How to Make Lemon Crumb Bars
Step 1: Prepare Your Oven and Crust
Preheat your oven to 350°F (175°C). In a large bowl, mix together the flour, sugar, baking powder, melted butter, and salt until the mixture is crumbly. This step creates the base for your bars. Remember to reserve 1/2 cup of this mixture for the topping later! Press the remaining crumb mixture firmly into the bottom of an 8×8-inch baking pan lined with parchment paper. Bake it for 12-15 minutes until it turns lightly golden—this will give your crust a lovely texture.
Step 2: Whisk Together the Filling
While your crust is baking, grab another bowl and whisk together the eggs, sugar, flour, lemon juice, and lemon zest until smooth. This filling is where all that wonderful zesty flavor comes from! It’s essential to get it nice and creamy so that it bakes evenly over your crust.
Step 3: Assemble Your Bars
Once your crust has baked and cooled slightly, pour the lemon mixture evenly over it. Don’t forget to sprinkle that reserved crumb mixture on top! This will create a delightful crumble that contrasts beautifully with the smooth filling.
Step 4: Bake Again
Now it’s time for another round in the oven! Bake your assembled bars for an additional 20-25 minutes or until you see that the filling is set and the top is lightly golden. The aroma will fill your kitchen—trust me; you’ll want to stick around for this!
Step 5: Cool and Serve
Let your Lemon Crumb Bars cool completely at room temperature before chilling them in the refrigerator for at least an hour. Chilling helps firm them up nicely. When you’re ready to serve them, slice into squares and dust with powdered sugar if desired. Enjoy every delightful bite!
Pro Tips for Making Lemon Crumb Bars
Making lemon crumb bars can be a delightful experience, and with these tips, you’ll ensure they turn out perfectly every time!
-
Use fresh lemons: Fresh lemon juice and zest make a huge difference in flavor compared to bottled options. The vibrant, tangy taste of fresh lemons truly elevates the dish.
-
Chill before slicing: Allowing the bars to chill in the refrigerator for at least an hour after baking helps them set properly. This makes slicing easier and results in cleaner edges for a more appealing presentation.
-
Monitor baking times: Keep an eye on both baking stages. Every oven is different, and slight variations in time can turn your bars from perfectly golden to overdone.
-
Line your pan with parchment paper: This simple step makes it much easier to lift the cooled bars out of the pan for slicing. It also ensures that the bottom doesn’t stick, preserving that lovely crust.
-
Dust with powdered sugar just before serving: This keeps the sugar from getting absorbed into the bars and maintains a beautiful presentation. Plus, it adds an extra touch of sweetness!
