Instructions

1. Preheat oven to 350F (175C) and prepare a 9×13-inch baking pan by lining with parchment paper and applying a light grease coating.
2. Create the crumb base by mixing flour, sugar, and salt in a large mixing bowl, then incorporate melted butter until the mixture develops a sandy, crumbly texture.

5. Carefully pour the lemon filling over the prepared crust, ensuring an even distribution across the entire surface.
6. Generously sprinkle the remaining crumb mixture over the lemon filling, creating a textured, crumbly topping.
7. Slide the pan into the preheated oven and bake for 20-25 minutes, watching for a golden-brown coloration on the crumb topping.
