Ingredients
- 1 cup (2 sticks) unsalted butter, melted
- 2 cups all-purpose flour
- 1 ½ cups granulated sugar, divided
- ½ teaspoon baking powder
- ½ teaspoon salt
- 1 large egg
- 2 tablespoon freshly grated lemon zest (about 2 lemons)
- ⅓ cup freshly squeezed lemon juice (about 2 lemons)
- 1 (14-oz) can sweetened condensed milk
- 1 teaspoon pure vanilla extract
Directions
Step 1: Prep & Preheat
Preheat your oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment paper, allowing some overhang for easy removal. Lightly grease the paper.
Step 2: Make the Crumb Mixture
In a large bowl, combine the melted butter, flour, 1 cup of the sugar, baking powder, lemon zest, and salt. Mix until the dough is crumbly but holds together when pressed.
Step 3: Form the Base
Press two-thirds of the crumb mixture firmly into the bottom of your prepared pan to form an even layer. Set aside the rest for the topping.
Step 4: Prepare the Lemon Filling
In a medium bowl, whisk together the egg, remaining ½ cup sugar, lemon juice, sweetened condensed milk, and vanilla extract until smooth and creamy.
Step 5: Layer & Top
Pour the lemon filling evenly over the crust. Sprinkle the reserved crumb mixture over the top, gently pressing it into the lemon layer.
Step 6: Bake
Bake for 28-32 minutes, or until the top is golden brown and the center is just set. Cool completely in the pan.
Step 7: Slice & Serve
Once cooled, lift the Lemon Crumb Bars from the pan using parchment overhang. Slice into 18 bars. Dust with powdered sugar if desired and enjoy!

- You can line the pan with foil instead of parchment if that's what you have on hand.
Variations
