Description
These Lemon Crumb Bars feature a buttery shortbread base, bright and creamy lemon filling, and a golden crumb topping that stays perfectly textured even after cooling.
Ingredients
For the Base and Topping:
- 2 cups all-purpose flour
- ½ cup powdered sugar
- 1 cup cold unsalted butter, cubed
- ¼ teaspoon salt
- ½ cup old-fashioned oats
For the Lemon Filling:
- 4 large eggs, room temperature
- 1½ cups granulated sugar
- ¼ cup all-purpose flour
- ⅓ cup fresh lemon juice
- 2 tablespoons lemon zest
- ¼ teaspoon salt
For Garnish:
- Powdered sugar for dusting (optional)
Instructions
1. Preheat oven to 350°F (175°C) and line a 9×13-inch pan with parchment.
2. In a bowl, whisk flour, powdered sugar, and salt. Cut in cold butter until coarse crumbs form. Mix in oats. Reserve 1 cup for topping.
3. Press remaining mixture into pan and bake for 18–20 minutes until edges are golden.
4. Whisk eggs and sugar. Add flour, lemon juice, zest, and salt. Mix until smooth.
5. Pour filling over hot crust. Sprinkle reserved topping evenly over it.
6. Bake for 22–25 minutes until filling is set and topping is golden.
7. Cool for at least 2 hours before slicing. Dust with powdered sugar if desired.
Notes
- Use cold butter for the crust and topping to maintain texture.
- Always pre-bake the crust to avoid sogginess.
- Room temperature eggs prevent curdling in the lemon filling.
- Cool completely before slicing for clean cuts.
- Coat parchment paper with a light spray of baking oil for easiest release.
