Ingredients You’ll Need

Every component of this Easy Gluten-Free Lemon Bars Recipe plays a role in achieving the perfect balance of crisp crust and silky filling. Here’s what you’ll need:

  • Unsalted butter (½ cup, softened) – Creates richness and a tender base.

  • Granulated sugar (¼ cup + 1 cup) – Sweetens both the crust and filling while balancing tartness.

  • Gluten-free all-purpose flour (1 cup + ½ cup) – A good blend mimics wheat flour’s texture. Brands with xanthan gum are recommended.

  • Kosher salt (⅛ tsp + ⅛ tsp) – Enhances flavors without overpowering sweetness.

  • Lemon zest (2 tbsp total, divided) – Adds aromatic oils that elevate lemon flavor.

  • Vanilla extract (1 tsp) – Adds warmth to the buttery crust.

  • Eggs (3, room temperature) – Give the filling its custard-like consistency.

  • Fresh lemon juice (½ cup) – The star ingredient that brings the tangy punch.

  • Powdered sugar (for dusting) – A finishing touch that makes bars irresistible.

👉 Substitutions

  • Dairy-free: Use vegan butter substitute.

  • Low-sugar: Swap with monk fruit or coconut sugar (though color may change).

  • Citrus twist: Replace lemon with lime, orange, or grapefruit for variety.

Step-by-Step: How to Make Easy Gluten-Free Lemon Bars Recipe

Step 1: Prepare the Pan

Preheat oven to 350°F (175°C). Grease and line an 8×8-inch pan with parchment paper, leaving an overhang for easy lifting later.

Step 2: Make the Crust

Cream together butter, ¼ cup sugar, zest, and vanilla until light. Mix in 1 cup gluten-free flour + ⅛ tsp salt until crumbly. Press firmly into the pan. Dock with a fork to avoid puffing.

Step 3: Bake the Crust

Bake for 15–20 minutes, until lightly golden. This ensures a firm, crunchy base to hold the filling.

Step 4: Whisk the Filling

Whisk eggs, 1 cup sugar, lemon juice, zest, ½ cup flour, and ⅛ tsp salt until silky smooth. The flour helps the filling set without cracking.

Step 5: Bake Again

Pour filling over warm crust. Bake for 20–25 minutes, until the filling is set but slightly jiggles in the center.

Step 6: Cool & Slice

Cool completely before removing from pan. Dust with powdered sugar, then cut into 16 perfect squares.

Pro Tips for Perfect Gluten-Free Lemon Bars
How do I keep gluten-free lemon bars from crumbling?

Use a gluten-free flour blend with xanthan gum—it acts like gluten, holding structure.

Why is my lemon bar filling runny?

It’s underbaked. The center should jiggle slightly but firm up as it cools.

Can I use bottled lemon juice?

Fresh juice is best—bottled can taste flat or bitter, missing that zesty punch.

How do I make them dairy-free?

Substitute butter with coconut oil or vegan margarine. The crust will still be crisp and flavorful.

Best Ways to Serve

These classic gluten-free lemon bars shine on their own, but they’re also versatile:

🌿 Pair with fresh berries or whipped cream.

🍵 Serve alongside tea or coffee for a refreshing break.

🎉 Use as part of a dessert platter with brownies and cookies.
