Ingredients for Lemon Crumb Bars
- 1 cup (226g) unsalted butter, melted
- 2 cups (250g) all-purpose flour
- 1 cup (200g) granulated sugar, divided
- 1/2 teaspoon salt
- 1 teaspoon vanilla extract
- 2 large eggs
- 1 tablespoon finely grated lemon zest (from 1-2 lemons)
- 1/3 cup (80ml) fresh lemon juice
- 2 tablespoons all-purpose flour (for filling)
- Powdered sugar, for dusting (optional)
How to Make Lemon Crumb Bars
Step 1: Prepare the Crumb Mixture
Preheat your oven to 350°F (175°C). Line an 8×8-inch (20×20 cm) baking pan with parchment paper, leaving an overhang for easy removal. In a medium bowl, combine melted butter, 2 cups flour, 1/2 cup sugar, salt, and vanilla extract. Mix until coarse crumbs form.
Step 2: Create the Base
Press about two-thirds of the crumb mixture evenly into the bottom of the prepared pan. Use the back of a spoon or your fingertips to pack it firmly. Bake for 15 minutes, or until lightly golden at the edges.
Step 3: Make the Lemon Filling
While the base bakes, whisk together eggs, remaining 1/2 cup sugar, lemon zest, lemon juice, and 2 tablespoons flour until smooth and slightly thickened.
Step 4: Assemble & Bake the Lemon Crumb Bars
Pour the lemon filling over the warm, baked base. Sprinkle the remaining crumb mixture evenly over the top. Return to the oven and bake for 25-28 minutes, or until the filling is just set and the crumb topping is golden.
Step 5: Cool & Serve
Let the Lemon Crumb Bars cool completely in the pan. For clean slices, chill for at least 1 hour. Lift out using the parchment paper, cut into bars, and dust with powdered sugar if desired.

Pro Tips for Perfect Lemon Crumb Bars
- Use fresh lemon juice for the best, brightest flavor—bottled juice just isn’t the same. Learn more about juicing lemons efficiently.

- For extra crunch, add a handful of chopped nuts to the crumb topping.
FAQ: Lemon Crumb Bars
- Can I double the recipe for a 9×13-inch pan?
- Yes, simply double all ingredients and bake in a 9×13-inch pan. You may need to increase the baking time by 5-7 minutes.
- Can I use bottled lemon juice?
- Fresh lemon juice is highly recommended for the best flavor, but bottled can be used in a pinch—just note that the taste may be less vibrant. See more at Bon Appétit.
