The result is a clean, vibrant dessert with a soft bite and a bold lemon flavor.
You will also love how reliable this recipe is. The crust is sturdy enough to hold the filling, but still tender once chilled. The lemon layer bakes up smooth and silky, and the bars slice beautifully after cooling. Since they are both gluten-free and dairy-free, they are a great choice when you need a dessert that fits different dietary needs without sacrificing taste.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the crust:
1 1/2 cups gluten-free all-purpose flour
1/2 cup almond flour
1/2 cup granulated sugar
1/4 teaspoon salt
3/4 cup refined coconut oil, melted
1 teaspoon vanilla extract
For the lemon filling:
1 1/4 cups granulated sugar
1/4 cup gluten-free all-purpose flour
4 large eggs
2/3 cup fresh lemon juice
1 tablespoon lemon zest
1/2 teaspoon baking powder
1/8 teaspoon salt
Optional for finishing:
2 tablespoons powdered sugar for dusting
Extra lemon zest for garnish
Directions
Preheat your oven to 350°F. Line an 8×8-inch baking pan with parchment paper, leaving a little overhang on the sides so the bars are easy to lift out later.
In a medium mixing bowl, combine the gluten-free flour, almond flour, granulated sugar, and salt for the crust. Pour in the melted coconut oil and vanilla extract, then stir until the mixture forms a soft dough.
Press the crust mixture evenly into the prepared pan. Use the back of a spoon or the bottom of a measuring cup to pack it down firmly, especially into the corners. Bake for 15 minutes, or until the edges are just lightly golden.
While the crust bakes, make the filling. In a large bowl, whisk together the sugar and gluten-free flour. Add the eggs, lemon juice, lemon zest, baking powder, and salt. Whisk until the mixture is smooth and fully combined.
Remove the crust from the oven and pour the lemon filling over the hot crust. Return the pan to the oven and bake for 22 to 25 minutes, or until the center looks set and no longer appears liquid.
Let the bars cool completely at room temperature. Then transfer the pan to the refrigerator and chill for at least 2 hours. Once cold, lift the bars out using the parchment, slice into squares, and dust lightly with powdered sugar if desired.
Servings and timing
This recipe makes 12 lemon bars.
Prep time: 15 minutes
Bake time: 37 to 40 minutes
Chill time: 2 hours
Total time: about 3 hours
Variations
For a brighter citrus flavor, add an extra teaspoon of lemon zest to the filling. If you enjoy a slightly deeper taste, replace 1 tablespoon of the lemon juice with fresh lime juice.
You can also make these bars with orange or Meyer lemon juice for a softer citrus profile. For a more delicate crust, use all gluten-free all-purpose flour and skip the almond flour. If you like a richer base, add 2 tablespoons of unsweetened shredded coconut to the crust mixture.
Storage/Reheating
Store the bars in an airtight container in the refrigerator for up to 5 days. Place parchment paper between layers if you are stacking them so the tops stay neat.
For longer storage, freeze the bars in a single layer until firm, then transfer them to a freezer-safe container. They can be frozen for up to 2 months. Thaw in the refrigerator overnight before serving.
These bars are best served chilled, so reheating is not necessary. If you prefer a softer texture, let them sit at room temperature for 10 to 15 minutes before eating.
FAQs
Why did my lemon bars not set properly?
They usually need either a little more baking time or more chilling time. The center should look set before you remove the pan from the oven.

Fresh lemon juice gives the best flavor, but bottled lemon juice can work in a pinch.
How do I get clean slices?
Chill the bars thoroughly and wipe your knife clean between each cut.
Can I make these ahead of time?

Not much, especially if you use refined coconut oil, which has a more neutral flavor.
Can I make this recipe without almond flour?
Yes, replace the almond flour with the same amount of gluten-free all-purpose flour.

No, it is optional. The bars are delicious with or without it.
