How to Make Lemon Crumb Bars
Follow these simple steps to prepare this delicious dish:
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking dish or line it with parchment paper for easy removal later.
Step 2: Make the Crust
In a large mixing bowl, combine flour and granulated sugar. Cut in softened butter until the mixture resembles coarse crumbs. Press this mixture firmly into the bottom of the prepared baking dish.
Step 3: Bake the Crust
Place the crust in the preheated oven and bake it for about 15 minutes or until lightly golden around the edges. Remove it from the oven and let it cool slightly while you prepare the filling.
Step 4: Prepare the Filling
In another bowl, whisk together eggs, granulated sugar, lemon juice, and lemon zest until well combined. Stir in flour until just blended.
Step 5: Add Filling Over Crust
Pour the lemon filling over your warm crust. Return it to the oven and bake for an additional 20-25 minutes until set.
Step 6: Cool and Serve
Allow the lemon crumb bars to cool completely before slicing into squares. Dust with powdered sugar before serving to enhance presentation.
Transfer to plates and enjoy these delightful treats.
Tips and Tricks
Here are some helpful tips to ensure the best results for your dish:
- Use Fresh Lemons: Freshly squeezed lemon juice provides better flavor than bottled alternatives; don’t skip on zesting.
- Chill Before Cutting: Letting them cool completely helps achieve cleaner slices without crumbling.
- Add Extra Zest: For more intense flavor, consider adding additional lemon zest into both crust and filling.
Mistakes to avoid
- Using Old Lemons: Fresh lemons are essential for making delicious Lemon Crumb Bars. Using old or stale lemons can ruin the flavor and diminish the zestiness that makes these bars so appealing. Always select bright, firm lemons with a smooth skin. When squeezing fresh juice, remember that a little goes a long way, so don’t overdo it. The vibrant taste of the lemon is key to achieving that perfect balance of tartness and sweetness in your bars.
- Overbaking the Crust: A common mistake is overbaking the crust for your Lemon Crumb Bars. Keep an eye on it as it bakes; you want a lightly golden color rather than a deep brown. Overbaking can lead to a dry and crumbly texture that detracts from the overall experience. Aim for about 15-20 minutes in the oven and allow it to cool before adding your lemon filling for the best results.
- Skipping the Chilling Time: Some people may feel tempted to skip chilling their Lemon Crumb Bars after baking. However, chilling is crucial for achieving the right texture and flavor integration. It allows the filling to set properly, making slicing easier and enhancing its taste. Be patient and let your bars chill in the refrigerator for at least two hours before serving. This extra step will significantly improve your final product.
Serving Suggestions
This Lemon Crumb Bars is versatile and pairs wonderfully with:
- Coffee or Tea: Enjoy these delightful bars alongside a warm cup of coffee or tea. The zesty lemon flavor complements the rich taste of both beverages, making for a perfect afternoon treat.
- Fresh Berries: Serve with a side of fresh berries like strawberries or blueberries. Their sweetness balances the tartness of the bars, creating a refreshing contrast that enhances your dessert experience.
- Ice Cream: A scoop of vanilla ice cream on top of your Lemon Crumb Bars adds creaminess and indulgence. This combination makes for an irresistible dessert that everyone will love.
