Ingredients:

Crust:

  • 1½ cups almond flour (finely ground; gluten-free)
  • ¼ cup coconut flour (low-FODMAP portion)
  • ⅓ cup pure maple syrup (gentler than honey)
  • ¼ cup refined coconut oil, melted (dairy-free)
  • ½ tsp vanilla extract
  • ¼ tsp sea salt

Lemon Filling:

  • 3 large eggs, room temperature
  • ½ cup granulated sugar
  • ¼ cup pure maple syrup
  • ⅔ cup fresh lemon juice (about 3–4 lemons)
  • 1 tbsp lemon zest
  • 2 tbsp coconut flour (for thickening; low-FODMAP portion)
  • ¼ tsp sea salt

Materials needed:

  • 8x8 inch baking pan
  • Parchment paper
  • Medium mixing bowl
  • Whisk
  • Spatula
  • Measuring cups and spoons
  • Oven preheated to 350°F

How to Make It:

  1. Line your 8x8 pan with parchment paper, leaving some overhang for easy lifting later. This makes clean slicing much easier.
  2. In a medium bowl, combine almond flour, coconut flour, salt, maple syrup, melted coconut oil, and vanilla. Mix until a soft dough forms. It should feel slightly moist but not greasy.
  3. Press the mixture evenly into the pan. Use your fingers or the back of a spoon to smooth it out. If it looks thin, that is okay. It bakes into a sturdy base.
  4. Bake the crust for 12 to 15 minutes until lightly golden at the edges and fragrant. You want gentle color, not dark brown.
  5. Remove from oven and let cool for 10 minutes while you prepare the filling. A slightly warm crust is perfect.
  6. In a bowl, whisk eggs, sugar, maple syrup, lemon juice, lemon zest, coconut flour, and salt until smooth. The mixture should look glossy and pale yellow.
  7. Pour filling over the warm crust. Tap the pan lightly on the counter to release air bubbles. Do not worry if it seems thin. It sets as it bakes.
  8. Return the pan to the oven and bake for 18 to 22 minutes until the center is just set and no longer jiggles in the middle. We are going for softly firm, not dry.
  9. Let cool at room temperature for 1 hour, then refrigerate at least 2 hours before slicing. Chilling helps the bars hold their shape cleanly.
  10. Lift out using parchment and slice into 12 squares. Wipe the knife between cuts for neat edges.

If your kitchen smells bright and citrusy, you did it right.
