How to Make Lemon Crumb Bars
Step 1: Prepare the Crust
Preheat oven to 350°F (175°C).
Mix flour, sugar, and salt in a bowl.
Cut in cold butter until mixture is crumbly.
Press 2/3 of the crumb mixture into the bottom of a greased 8×8-inch baking pan.
Bake for 15 minutes until lightly golden.
Step 2: Make the Lemon Filling
In a medium bowl, whisk eggs, sugar, flour, lemon juice, and lemon zest until smooth.
Pour over the pre-baked crust.
Step 3: Add the Crumb Topping
Sprinkle remaining crumb mixture evenly over the lemon layer.
Return to the oven and bake for 20–25 minutes, until the topping is golden and filling is set.
Step 4: Cool & Serve
Allow bars to cool completely in the pan.
Optional: dust with powdered sugar before slicing into squares.
