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 degrees F. 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.

Use clean prep surfaces, dedicated utensils, and fresh parchment or cookware when preparing coconut flour lemon bars with chia seed crust for someone with celiac disease.
Texture Expectations
Keep the crust dense and set, and the filling springy after chilling. Cut with a sharp knife when fully cool.
Dining With Non-GF Family Note
Cut into bite-sized squares for family snacks and keep dessert prep separate from savory stations when serving mixed-diet families.
