Ready to bake? Here’s what you’ll need:


  • For the crust:
    • 2 cups almond flour
    • 1/2 cup melted butter (or dairy-free alternative)
    • 1/2 cup sugar-free powdered sugar
  • For the filling:
    • 1/4 cup softened butter (or dairy-free alternative)
    • 1/2 cup lemon juice
    • 1/2 cup sugar-free powdered sugar
    • 5 large eggs (see notes for vegan option)
    • 1 extra large egg yolk (see notes for vegan option)
    • 1 1/2 tablespoons coconut flour


  1. Preheat your oven to 350¬įF (180¬įC) and line an 8×8 inch pan with parchment paper.
  2. Make the crust: In a bowl, mix almond flour, melted butter, and powdered sugar until crumbly. Press the mixture into the bottom of the pan and bake for 15 minutes, or until golden brown.
  3. While the crust bakes, whip up the filling: Cream together softened butter, lemon juice, and powdered sugar. Add eggs, extra yolk, and coconut flour, mixing well until smooth.
  4. Pour the filling over the hot crust and bake for 20-22 minutes: The center should be firm but still slightly jiggly.
  5. Chill out!: Let the bars cool completely in the pan, then refrigerate for at least 2 hours for them to set.
  6. Time to shine! Sprinkle with extra powdered sugar and enjoy a taste of sunshiney lemon goodness!

Tips & Tricks:


  • Move quickly:¬†Pour the filling onto the hot crust right after baking to avoid separation.
  • Don’t overbake:¬†These bars continue to firm up as they cool and refrigerate.
  • Coconut-free?¬†Try 1/4 teaspoon xanthan gum or even all-purpose flour (6 tablespoons).
  • Zest it up!¬†Add some lemon zest for an extra punch of flavor.
  • Storage: Keep these beauties in the fridge for up to 2 weeks, or freeze them for longer.
