Ingredient Breakdown

For the Crust

Graham Crackers (24 squares): Crushed to create the crunchy, flavorful base.
Unsalted Butter (4 tbsp, melted): Binds the crumbs together and adds a rich, buttery taste.
Sugar (¼ cup): Sweetens the crust and helps it crisp up during baking.

For the Filling

Egg Yolks (2): Provide structure and richness to the creamy lemon filling.
Sweetened Condensed Milk (12 oz can): Adds sweetness and a luscious, smooth texture.
Lemon Juice (½ cup): The star ingredient that delivers bold citrus flavor and tang.

Pro Tips

Use fresh lemon juice – Bottled lemon juice won’t give the same brightness and zest.
Chill before slicing – Refrigerating the bars ensures clean, sharp cuts.
Line with parchment – Overhang makes removing the bars from the pan effortless.
Cool crust completely – Prevents the filling from seeping into the crust.
Use room-temperature egg yolks – Helps them whisk smoothly into the condensed milk.

Ingredient Swaps or Variations

Crust alternatives: Use vanilla wafers or shortbread cookies instead of graham crackers.
Flavor twist: Swap lemon juice for lime or orange juice for a fun variation.
Topping ideas: Dust with powdered sugar, add whipped cream, or garnish with lemon zest.
Gluten-free option: Use gluten-free graham crackers for the crust.
Nutty addition: Add a sprinkle of shredded coconut or finely chopped almonds into the crust mix.

Serving Suggestions

Serve these creamy lemon squares chilled for maximum flavor and firmness. Pair with fresh berries for a colorful presentation, or plate alongside a dollop of whipped cream. For a refreshing contrast, serve with a glass of iced tea or lemonade. They also make an elegant dessert when garnished with a curl of lemon zest or a mint sprig.
