How to Make Lemon Crumb Bars
Step 1: Prepare the Crust
Preheat your oven to 350°F (175°C). In a large bowl, combine all-purpose flour, granulated sugar, baking powder, melted butter, and salt until the mixture is crumbly. This step is crucial as it forms the base of your bars. Press about three-quarters of this mixture into an 8×8-inch baking pan lined with parchment paper. Bake for 12-15 minutes until lightly golden.
Step 2: Make the Lemon Filling
In another bowl, whisk together the eggs, granulated sugar, additional flour, fresh lemon juice, and lemon zest until smooth. This filling is where all that zesty goodness comes from! Mixing it well ensures that every bite is bursting with lemon flavor.
Step 3: Combine and Bake
Once your crust has baked, pour the lemon mixture evenly over it. Don’t forget to sprinkle the reserved crumb mixture on top; this creates that lovely crumbly finish! Bake again for an additional 20-25 minutes or until the filling is set and slightly golden on top.
Step 4: Cool and Serve
Let the bars cool completely in the pan before transferring them to the refrigerator for at least one hour. Chilling makes them easier to slice and enhances their flavors. Once cooled, cut into squares and dust with powdered sugar before serving—just like a little sprinkle of magic on top!
And there you have it—delicious Lemon Crumb Bars ready for you and your loved ones to enjoy!
Pro Tips for Making Lemon Crumb Bars
Making these lemon crumb bars is a breeze, but a few handy tips can elevate your baking game!
-
Use fresh lemons: Freshly squeezed lemon juice and zest provide the brightest flavor that bottled alternatives simply can’t match. This ensures your bars are bursting with that delicious citrus tang.
-
Chill before cutting: Allowing the bars to chill in the refrigerator for at least an hour not only helps them set properly but also makes cutting them into neat squares much easier. Plus, it enhances the refreshing taste!
-
Don’t skip the parchment paper: Lining your baking pan with parchment paper allows for easy removal of the bars without sticking. This little step saves you from messy cleanup and broken pieces.
-
Add a pinch of turmeric: If you want to enhance the color of your lemon filling, consider adding a tiny pinch of turmeric. It gives a lovely golden hue without altering the flavor.
-
Experiment with flavors: Feel free to mix things up by adding a teaspoon of vanilla extract or even some poppy seeds for added texture and flavor. This personalization can make your bars uniquely yours!
