How to Make Lemon Crumb Bars
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). This step is crucial because starting with a hot oven ensures that your crust bakes evenly and gets that lovely golden color.
Step 2: Prepare the Crust
In a large bowl, mix together the flour, sugar, baking powder, melted butter, and salt until crumbly. This mixture should resemble coarse crumbs. Reserve 1/2 cup of this mixture for topping later. Press the remaining mixture into the bottom of an 8×8-inch baking pan lined with parchment paper. Bake it for about 12-15 minutes until lightly golden. The crust sets the stage for your luscious filling!
Step 3: Make the Lemon Filling
While your crust is baking, whisk together the eggs, sugar, flour, lemon juice, and lemon zest in another bowl until smooth. This step brings all those bright flavors together and creates that deliciously tangy filling you’ll love.
Step 4: Assemble Your Bars
Once the crust has baked and cooled slightly, pour the lemon mixture evenly over it. Sprinkle the reserved crumb mixture on top to add texture. This layer will give you those lovely crumbs once baked!
Step 5: Bake Again
Bake everything together for an additional 20-25 minutes or until the filling is set and the top is lightly golden. Watching it rise in the oven is so satisfying!
Step 6: Cool and Serve
Let your bars cool completely before chilling them in the refrigerator for at least one hour. This helps them set perfectly! Once chilled, slice them into squares and dust with powdered sugar just before serving—a lovely finishing touch.
These Lemon Crumb Bars are not only easy to make but also incredibly delicious! Enjoy making these treats; I’m sure they’ll become a new favorite in your home!
