1. Classic Gluten Free Lemon Bars with Shortbread Crust

A perfect lemon bar hits that sweet-tart spot, and this gluten free version doesn't compromise on texture or flavor. The almond flour shortbread crust bakes up buttery and crisp, providing a sturdy base for the bright, silky lemon filling. Whether you're making them for a bake sale or a simple weekend treat, these bars are as straightforward as they are satisfying.

Ingredients

• For the crust: 1 ½ cups almond flour
• ¼ cup coconut flour
• ¼ cup granulated sugar
• ½ cup cold unsalted butter, cut into small cubes
• ¼ teaspoon salt
• For the filling: 4 large eggs
• 1 ½ cups granulated sugar
• ⅓ cup fresh lemon juice (about 3 lemons)
• 2 tablespoons lemon zest
• ¼ cup gluten free all-purpose flour
• Powdered sugar for dusting

Instructions

1. Preheat oven to 350°F. Line an 8×8-inch baking pan with parchment paper.
2. Make the crust: In a food processor, combine almond flour, coconut flour, sugar, and salt. Add cold butter cubes and pulse until mixture resembles coarse sand.
3. Press the crust mixture evenly into the prepared pan. Bake for 15-18 minutes until lightly golden. Let cool slightly.
4. While crust cools, make the filling: In a medium bowl, whisk eggs and sugar until smooth. Add lemon juice, lemon zest, and gluten free flour; whisk until well combined.
5. Pour filling over the warm crust. Bake for 20-25 minutes until the filling is set and edges are lightly browned. Cool completely at room temperature, then refrigerate for at least 2 hours.
6. Dust with powdered sugar before cutting into squares. Use a sharp knife wiped clean between cuts for neat edges.

Serving Tip

For the cleanest slices, chill the bars thoroughly and use a sharp knife dipped in hot water, wiping dry between cuts. Serve cold or at room temperature; they keep well in the fridge for up to 5 days.

2. Coconut Lemon Bars with Toasted Coconut Topping

For a tropical escape in dessert form, these coconut lemon bars swap the usual butter crust for one made with coconut flour, giving them a tender, nutty base that complements the bright lemon filling.

They're quick to assemble and perfect for anyone who loves a little texture with their citrus.

Instructions

1. Preheat oven to 350°F and line an 8×8-inch baking pan with parchment paper.
2. In a bowl, mix 1 cup coconut flour, melted coconut oil, maple syrup, and salt until a crumbly dough forms. Press evenly into the bottom of the pan.
3. Bake the crust for 10 minutes, until lightly golden. Remove and set aside.

FAQ

Can I use regular flour instead of gluten free flour in these recipes?

Yes, you can substitute all-purpose flour 1:1 in most recipes, but the texture may change slightly. For best results, use a good gluten free flour blend that includes xanthan gum.

How do I store gluten free lemon bars?

Store them in an airtight container in the refrigerator for up to 5 days. They also freeze well for up to 3 months—just wrap tightly and thaw in the fridge.

Can I make these lemon bars dairy free?

Absolutely. Use dairy-free butter or coconut oil in the crust, and swap any cream cheese or butter in the filling with vegan alternatives. The vegan recipe in this list is already dairy free.

Why did my lemon bars turn out too soft or runny?

This usually happens if the bars are underbaked or if the lemon filling wasn't cooked long enough to set. Make sure to bake until the center is just set and no longer jiggly.

Can I reduce the sugar in these recipes?

You can reduce sugar by up to 25% without major issues, but keep in mind that sugar helps with texture and setting. For a less sweet bar, try using a sugar substitute like monk fruit or erythritol.
