Paleo Lemon Bars Recipe: Bright, Grain-Free, Honey-Sweetened
These paleo lemon bars stack a buttery coconut-and-tapioca-flour shortbread base with a silky lemon curd top, sweetened only with raw honey. No white flour, no refined sugar, no artificial colors.
The curd sets bright yellow from real egg yolks and delivers the sharp-sweet balance that store-bought lemon bars usually miss. Each bar runs about 175 calories with 5 grams of protein.
Perfect for a spring brunch, an Easter dessert table, or anyone eating paleo who has been missing a good citrus dessert. Yields 16 bars from a standard 8×8 pan.
What Makes This Version Work
Coconut flour shortbread is a different beast from wheat shortbread. It has no gluten to develop, so overmixing is impossible, but it also lacks structure, so the crust needs to be pressed firmly and pre-baked (blind baked) until deeply golden before the lemon layer goes on.
A soft or underbaked crust turns soggy under the wet curd. Coconut flour is thirsty, so the ghee and egg matter; press the crust firmly for a shortbread-like snap rather than a rustic crumb. For the curd, whisk eggs and yolks off heat first, then temper slowly with warm honey-lemon mixture to prevent scrambling.
Fresh lemon juice is non-negotiable; bottled juice gives you a dull, one-note tartness. Bake the assembled bars at 325 F just until the curd is set but still has a slight wobble in the center. Overbaking cracks the top.

Paleo Lemon Bars Recipe
Ingredients
For the crust
- 1/3 cup ghee You will have to keep it at room temperature
- 1/4 cup raw honey
- 1 egg room temp
- 2/3 cup coconut flour
- 1 tsp. pure vanilla extract
- 1/4 cup tapioca flour
- Grated Zest of 1 lemon
- 1/8 tsp. sea salt
For the Filling
- 1/2 cup freshly squeezed lemon You can get it by juicing about 4 lemons
- Grated zest get it using one lemon
- 1/3 cup with 1 tbsp. raw honey
- 1 tbsp. tapioca flour
- 3 large eggs along with 1 yolk
- 1/2 tsp. coconut flour
Instructions
- First, preheat your oven to 350°F. Line an 8 x 8-inch baking dish with parchment paper and spread butter across the bottom and sides.
- To make the crust, whisk all the ingredients until smooth. You can also use an electric mixer to blend everything well. Chill the mixture for 10 minutes.
- Press the crust mixture firmly into the bottom of the lined baking dish. Spread it evenly and poke it with a fork.
- As the crust bakes, combine the filling ingredients in a large bowl. Whisk until smooth, then set aside.
- Bake the crust for 10–12 minutes or until the edges turn light brown.
- Remove the crust from the oven and immediately pour the filling over it. Return the dish to the oven and bake for another 15–18 minutes.
- Let the pan cool on a wire rack, then refrigerate for about 2 hours. For the best results, refrigerate overnight.
- For serving, cut the chilled mixture into 16 square bars. Sprinkle with organic powdered sugar and top with grated lemon zest. Coconut whipped cream is an optional garnish.

Tips and Variations
Line the pan with parchment overhang so you can lift the whole slab out for clean cuts. Chill the bars fully in the fridge for at least 2 hours before slicing; warm bars tear rather than cut. Wipe your knife between slices with a warm damp cloth for professional edges.
Finish with a sprinkle of lemon zest right before serving.
Variations: swap 2 tablespoons of the lemon juice for lime for a lemon-lime bar, or add 1 tablespoon of ginger juice for a bright zing. Vegan version: use a cashew cream curd bound with coconut oil and thickened with agar, though the flavor will read more like a lemon cream tart than a classic bar.
For a lower-sugar version, swap the honey for a monk fruit-honey blend and reduce the total sweetener by 2 tablespoons; the natural lemon brightness carries.
Storage and Reheating
Refrigerate bars in an airtight container for up to 5 days. The curd firms up more as it chills, giving you an even cleaner bite on day two. Freeze pre-cut bars separated by parchment in a zip bag for up to 2 months; thaw in the fridge overnight. Serve cold or at cool room temperature; the curd loosens if it warms too much. No reheating needed; this is a cold dessert by design.
