How to Make Lemon Crumb Bars Step by Step

1. Preheat and Prepare

Preheat oven to 350°F (177°C). Line an 8×8 or 9×9 inch square baking pan with parchment paper and leave a slight overhang for easy lifting.

2. Make the Crust and Crumble

In a large bowl, mix melted butter, sugar, vanilla, and salt. Add flour and stir until combined. The dough will be crumbly but cohesive. Set aside 1 cup of the mixture for topping.

Press the remaining dough firmly into the bottom of the pan to form an even layer.

3. Prepare the Lemon Filling

In a medium bowl, whisk together sweetened condensed milk, lemon zest, lemon juice, and egg yolks until smooth and creamy.

Pour the filling over the crust and spread evenly.

4. Top and Bake

Sprinkle the reserved crumble mixture over the top. Bake for 25–30 minutes, or until the edges are lightly golden and the center is mostly set.

5. Cool and Chill

Let the bars cool at room temperature, then refrigerate for at least 2 hours before slicing. This helps the filling firm up and gives you clean, beautiful cuts.

If you like a little crunch, serve these with Cinnamon Sugar Tortilla Chips for a sweet snack board.

Common Mistakes to Avoid When Making Crumb Bars

• Using bottled lemon juice: It lacks the brightness and freshness of real lemons.
• Skipping the chill time: The bars need time to set or they’ll fall apart when sliced.
• Overmixing the crumble: You want a crumbly texture, not dough.
• Not lining the pan: Makes it difficult to remove the bars cleanly.
