Ingredients
Servings
12
- 1/2 cup chia seeds
- 1/3 cup unsweetened shredded coconut
- 1/4 cup coconut flour
- 1/4 cup pure maple syrup
- 1/4 cup coconut oil, melted
- 1/2 teaspoon pure vanilla extract
- Pinch of sea salt
- 4 large eggs
- 3/4 cup fresh lemon juice (about 4-5 lemons)
- 1 tablespoon lemon zest
- 1/2 cup pure maple syrup
- 1/4 cup coconut flour
- 1/4 teaspoon sea salt
Instructions
-
Preheat the oven to 350°F (175°C). Line an 8x8-inch square baking pan with parchment paper, leaving an overhang for easy removal.
-
Make the crust: In a medium bowl, combine chia seeds, shredded coconut, coconut flour, and sea salt. Stir well to mix dry ingredients evenly.
-
Add maple syrup, melted coconut oil, and vanilla extract to the dry ingredients. Mix thoroughly until the mixture forms a sticky, crumbly dough.
-
Press the crust mixture firmly and evenly into the bottom of the prepared baking pan. Use the back of a spoon or your fingers to compact it well.
-
Bake the crust for 10-12 minutes until lightly golden and set. Remove from the oven and set aside to cool slightly while preparing the filling.
-
Make the lemon filling: In a mixing bowl, whisk together eggs, fresh lemon juice, lemon zest, maple syrup, coconut flour, and sea salt until fully combined and smooth.
-
Pour the lemon filling over the warm crust, spreading it evenly with a spatula.
-
Return the pan to the oven and bake for an additional 15-17 minutes, or until the filling is just set and slightly firm to the touch.
-
Remove from oven and allow the bars to cool completely at room temperature, then refrigerate for at least 2 hours to fully set.
-
Once chilled, use the parchment paper overhang to lift bars out of the pan. Cut into 12 squares.
-
Serve chilled or at room temperature. Store leftovers in an airtight container in the refrigerator for up to 5 days, or freeze for longer storage.
Frequently Asked Questions

If you want to customize this gluten-free lemon bar recipe to fit your preferences or dietary restrictions, consider these substitutions:
- Chia Seeds: Substitute with ground flaxseeds as a nut-free alternative and binding agent for the crust.
- Unsweetened Shredded Coconut: Omit or replace with crushed gluten-free cereal flakes to maintain a grain-free texture.
- Maple Syrup: Swap with agave nectar or honey for sweetness; note honey is not vegan.
- Coconut Oil: Use melted avocado oil or another neutral oil instead of coconut oil if desired.
- Eggs: For a vegan version, replace each egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, set to gel), though texture may vary slightly.
- Coconut Flour: Almond flour can be used as another gluten-free, grain-free option; adjust quantity due to different absorbency.
These ingredient swaps retain the paleo, grain-free, and dairy-free qualities of these lemon bars while accommodating various dietary needs.
Allergen Overlap Note
While these gluten-free recipes are carefully designed without gluten-containing ingredients, cross-contamination risks remain during food preparation. Many gluten-free ingredients might be processed in facilities that handle wheat, barley, rye, or other gluten grains. To ensure safety, always verify gluten-free certification on product labels and use dedicated utensils and cookware to prevent allergen overlap.
Recipes organized under categories such as Breakfast, Lunch, Dinner, Desserts, Snacks, Soups & Salads, Gluten-Free Baking, Quick & Easy, Family-Friendly, and Holiday & Seasonal may contain other allergens like dairy, nuts, eggs, or soy. Tags including dairyfree, nutfree, vegan, vegetarian, paleo, whole30 offer options that minimize exposure, but thorough ingredient checks remain essential, especially if you manage multiple allergies.
For those sensitive to gluten, dairy, and nuts, take extra precautions by sourcing allergen-free ingredients, maintaining strict kitchen hygiene, and avoiding shared storage containers. Choosing recipes tagged with glutenfree, dairyfreeoptions, nutfree, grainfree, and paleo often provides safer alternatives but vigilance is still required.
With careful ingredient selection and safe cooking practices, you can confidently enjoy delicious gluten-free meals tailored to your dietary needs while keeping your family safe.
Texture Expectations
Gluten-free baking often yields textures distinct from traditional wheat-based recipes due to the absence of gluten’s elasticity. For these Gluten-Free Coconut Flour Lemon Bars with Chia Seed Crust, expect a pleasant blend of textures reflecting their grain-free, paleo-friendly ingredients.
The crust, made from chia seeds, shredded coconut, and coconut flour, creates a firm yet slightly chewy base with a gentle crunch from the chia seeds. Unlike conventional flaky wheat crusts, this crust is sticky and dense, providing an interesting contrast to the smooth lemon filling.
The lemon filling, made with eggs and coconut flour, bakes to a soft, custard-like consistency that is creamy and slightly dense, without gluten’s typical fluffiness. It is tender yet firm enough to slice cleanly after chilling. The coconut flour adds a mild grainy texture that complements the tangy lemon flavor for a refreshing dessert experience.
These bars will be more delicate and less crumbly than traditional lemon bars. Chilling is key to fully set the filling and help maintain crust integrity. Expect moist, not dry or brittle, bars that provide a refreshing and wholesome dessert perfect for gluten-free, grain-free, and paleo diets.
Dining With Non Gf Family Note
Cooking gluten-free meals alongside non-gluten-free family members can be easy with proper separation and cleaning techniques. Use dedicated utensils, cutting boards, and cookware for gluten-free cooking. Store gluten-free ingredients separately and label clearly to avoid confusion.
Before and after food preparation, clean surfaces thoroughly and consider distinct kitchen tools such as toasters and colanders. To include everyone at mealtimes, opt for naturally gluten-free dishes categorized under Breakfast, Lunch, Dinner, and Desserts, ensuring all components are checked for gluten.
Educating family about gluten-free needs fosters understanding and support. Quick and easy gluten-free recipes simplify meal planning and let everyone enjoy safe, tasty dishes together without stress.
