Ingredients
- For the Crust and Crumb Topping:
- 1 cup unsalted butter,softened
- 1/2 cup granulated sugar
- 2 cups all-purpose flour,sifted
- 1/4 teaspoon salt
- 1 teaspoon pure vanilla extract
- For the Lemon Filling:
- 4 large eggs
- 1 1/2 cups granulated sugar
- 1/4 cup all-purpose flour
- 2/3 cup freshly squeezed lemon juice (about 3-4 lemons)
- 1 tablespoon lemon zest (finely grated)
Instructions
- Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking pan and line it with parchment paper, leaving some overhang for easy removal.
- Create the crust and crumb base: In a large bowl, cream together the softened butter and 1/2 cup sugar until light and fluffy, about 2-3 minutes using an electric mixer.
- Sift and fold in the 2 cups of flour and salt, mixing until crumbly but starting to hold together.stir in the vanilla extract.
- Press two-thirds of this crumb mixture firmly into the prepared baking pan to form an even, sturdy crust. Set aside the remaining crumbs for the topping.
- Bake the crust in the preheated oven for 15 minutes or until lightly golden. Remove and cool slightly.
- Prepare the lemon filling: In a separate bowl, whisk together eggs and 1 1/2 cups sugar until well combined and slightly frothy.
- Add the flour gradually, mixing smoothly to avoid lumps. Stir in the fresh lemon juice and zest. The mixture should be bright and velvety.
- pour the filling evenly over the warm crust, then sprinkle the reserved crumb topping over the filling, gently pressing down to adhere but still loose enough to maintain crumb texture.
- Bake for 20-22 minutes until the lemon layer is just set and the crumb topping is golden brown and fragrant.
- Cool completely in the pan on a wire rack to room temperature,then refrigerate for at least one hour to ensure clean slicing.
- Slice into bars using a sharp knife, wiping the blade between cuts for crisp edges.
Tips for Success and Variations
- Use fresh lemons for the juice and zest to maximize brightness and citrus aroma.
- For an extra-moist texture, substitute 2 tablespoons of the crust flour with finely ground almond meal.
- To keep crumb topping perfectly crumbly, chill the butter beforehand and handle the mixture gently.
- If your bars are too dense, try sifting the flour twice and avoid overmixing the filling.
- Make ahead: These bars store beautifully in the fridge for up to 3 days, or freeze them for a month wrapped tightly.
- Gluten-free Variation: Replace all-purpose flour with a gluten-free blend and add a teaspoon of xanthan gum for structure.

Q&A
Q&A: zesty Lemon Crumb Bars-bright, Tangy, and Irresistible!
Q1: what makes Zesty Lemon Crumb Bars stand out from other lemon desserts?
A1: These bars shine with their perfect balance of bright, tangy lemon filling paired with a buttery, golden crumb topping. Unlike a traditional lemon tart or pie, the crumb bars offer a delightful textural contrast-crispy edges, a soft, juicy center, and that irresistible streusel crunch that keeps you coming back for more.
Q2: How do you achieve the perfect tanginess in the lemon filling?
A2: The magic lies in using fresh lemon juice combined with just the right amount of zest.

A3: The crumb topping is all about the fat-to-flour ratio.

A pinch of coarse sugar sprinkled on top before baking adds a subtle crunch and a sparkling finish.
Q4: Can these bars be made ahead of time?
A4: Absolutely! These bars actually benefit from a bit of chilling as it helps the lemon filling set firmly, making slices clean and neat.

Q5: Are there any fun variations or add-ins to try?
