Ingredients
For the Crust and Topping
- 1 1/2 cups all-purpose flour
- 1/2 cup granulated sugar
- 1/2 teaspoon baking powder
- 1/2 cup unsalted butter, melted
- 1/4 teaspoon salt
For the Lemon Filling
- 2 large eggs
- 1 cup granulated sugar
- 1/4 cup all-purpose flour
- 1/3 cup fresh lemon juice
- 1 tablespoon lemon zest
How to Make Lemon Crumb Bars
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). In a large bowl, mix together the all-purpose flour, granulated sugar, baking powder, melted butter, and salt until the mixture is crumbly. Reserve 1/2 cup of this mixture for later use. Press the remaining mixture into the bottom of an 8×8-inch baking pan lined with parchment paper. Bake this crust for 12-15 minutes until it turns lightly golden.
Step 2: Prepare the Lemon Filling
In another bowl, whisk together the eggs, sugar, flour, fresh lemon juice, and lemon zest until smooth. This mixture will create a tangy contrast to the sweet crust.
Step 3: Assemble the Bars
Once your crust is baked, pour the lemon mixture evenly over it. Sprinkle the reserved crumb mixture on top to create that delightful texture contrast.
Step 4: Bake Again
Return to the oven and bake for an additional 20-25 minutes or until you see that the filling has set and the topping is lightly golden brown.
Step 5: Cool Down
Allow your lemon crumb bars to cool completely at room temperature. After cooling down, chill them in the refrigerator for at least one hour before slicing into squares. For an elegant finish, dust with powdered sugar before serving.

How to Perfect Lemon Crumb Bars

- Use Fresh Lemons: Fresh lemon juice and zest provide the best flavor compared to bottled options.
- Measure Ingredients Accurately: Accurate measurements ensure the right texture and taste in your bars.
- Keep an Eye on Baking Time: Overbaking can lead to dry bars, so check for doneness regularly during the last few minutes.
- Let Them Chill: Allowing the bars to cool completely before slicing helps them hold their shape better and enhances the flavors.
- Store Properly: Keep leftover bars in an airtight container in the fridge to maintain freshness for several days.
Best Side Dishes for Lemon Crumb Bars

Common Mistakes to Avoid
When making lemon crumb bars, even small errors can affect the outcome. Here are some common mistakes to be aware of:
- Skipping the chilling step: Not letting the bars cool properly can lead to a mushy texture. Always chill them in the refrigerator for at least one hour before slicing.
- Not measuring ingredients accurately: Using too much or too little of an ingredient can ruin the balance. Use a kitchen scale or measuring cups for precision.
- Overmixing the filling: Mixing too much can incorporate air and cause the filling to puff up. Mix just until combined for a smooth texture.
- Using bottled lemon juice: This can alter the flavor and freshness of your bars. Always use freshly squeezed lemon juice for the best taste.
- Neglecting to line the baking pan: This can make it difficult to remove the bars later. Always line your baking pan with parchment paper for easy lifting.
