What makes a good lemon bar?
A good lemon bar has a balance of sweet and tangy flavors, with a smooth, custardy lemon filling set on a firm, buttery crust. The filling should be firm enough to hold its shape but not too dry, while the crust should be crisp and buttery. The texture should be smooth, not too runny or too thick.

Print the recipe card below and gather your ingredients first:

- Preheat your oven to 350°F and spray a 9×13-inch pan with nonstick spray.
- In a mixing bowl, combine a box of lemon cake mix, eggs, and softened butter to form a dough.
- Press the dough evenly into the pan, then bake for 16-18 minutes until golden brown.
- Once done, let the bars cool.
- For the glaze, whisk together powdered sugar and lemon juice, then drizzle it on top.
- After they cool, sprinkle with extra powdered sugar, cut into squares, and chill for a cool treat.

Once the lemon bars are baked and cooled, place them in the fridge for at least an hour. Chilling them enhances the flavor and gives them a firmer texture.

Yes, powdered sugar is often sprinkled on top of lemon bars after they cool. It adds a sweet finishing touch that contrasts nicely with the tartness of the lemon filling and makes the bars look more appealing. It’s a simple and traditional way to enhance the flavor and appearance.
To make lemon bars less gooey, ensure that you bake them long enough for the filling to set completely, but not so long that it becomes too firm. Always allow the bars to cool completely before slicing, as they continue to set as they cool.
Absolutely! Store in the fridge for up to 3-4 days. The flavors even improve after a day or two in the fridge.
Yes! To freeze, let the bars cool completely, then wrap them tightly in plastic wrap and foil. They can be stored in the freezer for up to 3 months. Thaw them in the fridge before serving.
