Vegan Gluten-Free Lemon Bars with Almond Flour 🍋 That Taste Like Sunshine (Without the Sugar Crash)

You want a dessert that hits like a lemony mic drop—bright, bold, and ridiculously good—without the dairy, gluten, or regret. These Vegan Gluten-Free Lemon Bars with Almond Flour 🍋 pack bakery-level flavor with simple, clean ingredients you probably already have. Think zesty tang, silky custard vibes, and a tender shortbread crust that doesn’t crumble into chaos.

They set beautifully, slice clean, and look like they came from a chic café. Spoiler: they’re also way easier than they look.

The Secret Behind This Recipe

The magic is all about texture and balance. The crust uses almond flour and a touch of tapioca starch to create a shortbread that’s crisp at the edges and soft in the center—no dry, sandy crumble here.

For the lemon layer, a mix of fresh lemon juice, zest, and just the right starch blend mimics the classic curd texture without eggs. We use maple syrup for gentle sweetness and a more rounded flavor, plus coconut cream for a creamy mouthfeel that sets firm after chilling. The result?

A bright, smooth, sliceable lemon bar that’s equal parts refreshing and luxurious. No weird aftertaste, no gummy texture, no “healthy dessert” apology tour.

What You’ll Need (Ingredients)

• For the almond flour crust:
  • 2 cups fine almond flour
  • 3 tablespoons tapioca starch (or arrowroot starch)
  • 1/4 cup maple syrup
  • 1/4 cup melted coconut oil (refined for no coconut flavor) or vegan butter, melted
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon fine sea salt
• For the lemon filling:
  • 3/4 cup freshly squeezed lemon juice (about 4–5 lemons)
  • Zest of 2 lemons (about 2 tablespoons)
  • 1 cup full-fat coconut cream (scooped from the top of a chilled can)
  • 1/2 cup maple syrup (or 1/3 cup agave for a lighter flavor)
  • 1/3 cup tapioca starch (or arrowroot; see FAQ for cornstarch sub)
  • 1/4 teaspoon turmeric (optional, for color)
  • 1/4 teaspoon fine sea salt
  • 1 teaspoon vanilla extract
• To finish:
  • Powdered sugar or powdered erythritol for dusting (optional)
  • Thin lemon slices or extra zest for garnish (optional)

Let’s Get Cooking – Instructions

1. Prep the pan: Line an 8×8-inch (20×20 cm) square pan with parchment, leaving overhang for easy lifting. Preheat the oven to 350°F (175°C).
2. Make the crust: In a bowl, combine almond flour, tapioca starch, salt, maple syrup, melted coconut oil, and vanilla.

   Mix until a soft, slightly sticky dough forms.

3. Press and par-bake: Press the dough firmly and evenly into the lined pan. Dock lightly with a fork. Bake for 12–14 minutes until the edges are just turning golden.

   Set aside.

4. Whisk the filling: In a saucepan off heat, whisk lemon juice, zest, maple syrup, tapioca starch, salt, turmeric (if using), vanilla, and coconut cream until smooth—no lumps.
5. Thicken on the stove: Place the saucepan over medium heat. Whisk constantly for 5–7 minutes until the mixture thickens to a glossy, pudding-like consistency. Once it bubbles and tracks when whisked, it’s ready.
6. Pour and bake: Immediately pour the filling over the warm crust.

   Smooth the top with a spatula. Bake at 325°F (165°C) for 12–15 minutes, just until the edges look set and the center has a gentle jiggle.

7. Cool and chill: Cool at room temperature for 30 minutes. Then chill, uncovered, for at least 3 hours (preferably 4+) until fully set.
8. Slice and serve: Lift out using the parchment.

   Dust with powdered sugar if you like, slice into 16 squares with a sharp knife, and flex your dessert skills.

Storage Tips

• Fridge: Store in an airtight container for 4–5 days. Keep a sheet of parchment between layers to prevent sticking.
• Freezer: Freeze bars on a baking sheet, then transfer to a freezer-safe container for up to 2 months. Thaw in the fridge for best texture.
• Serving temp: For the cleanest slices, serve chilled.

  For a softer bite, let them sit at room temp 10–15 minutes.

Why This is Good for You

• Nutrient-dense fats: Almond flour brings vitamin E, magnesium, and fiber—not just empty carbs.
• Lower glycemic sweetener: Maple syrup offers trace minerals and a smoother blood sugar response than refined sugar (still dessert, but smarter).
• Citrus perks: Lemon juice and zest deliver vitamin C and antioxidant compounds with that mood-lifting aroma.
• Gluten- and dairy-free: Easy on digestion, inclusive for guests, and still tastes like the “real thing,” IMO.

Avoid These Mistakes

• Skipping the par-bake: A raw crust + wet filling = soggy bottom. Paul Hollywood would not approve.
• Under-thickening the filling: If it’s not pudding-thick on the stove, it won’t set right in the oven. Keep whisking.
• Overbaking: If you bake until fully firm, the filling turns rubbery.

  Pull when it still has a slight jiggle.

• Using light coconut milk: You need full-fat coconut cream for structure and silkiness. Light versions make it watery.
• Too much zest pith: Zest only the yellow. The white pith is bitter and will hijack your flavor.

Variations You Can Try

• Meyer lemon bars: Swap regular lemons for Meyer lemons for a sweeter, floral flavor.

  Reduce sweetener by 1–2 tablespoons if desired.

• Lemon-lavender twist: Steep 1 teaspoon culinary lavender in the lemon juice for 10 minutes, strain, and proceed. Fancy, right?
• Lemon-raspberry swirl: Dollop 1/3 cup raspberry puree on the filling before baking and swirl lightly with a knife.
• Coconut-lime bars: Replace lemon with lime juice and zest, and add 1/2 cup shredded coconut to the crust.
• Protein boost: Whisk 2 tablespoons unflavored or vanilla vegan protein powder into the crust. Add 1–2 teaspoons more coconut oil if it gets too dry.

FAQ

Can I use cornstarch instead of tapioca or arrowroot?

Yes.

Use 1/4 cup cornstarch in place of 1/3 cup tapioca. Cornstarch sets more firmly and can look slightly opaque, but it works well and slices clean.

What can I use instead of coconut cream?

Full-fat canned coconut milk (well-shaken) can work, but the set will be a touch softer. For no coconut flavor, use a thick, plain vegan yogurt and reduce lemon juice by 2 tablespoons to prevent curdling.

How do I make these refined sugar-free?

They already are if you skip the powdered sugar on top.

Maple syrup or agave sweeten the bars without refined granulated sugar. For even lower sugar, use a liquid monk fruit-maple blend; start with 1/3 cup and adjust to taste.

My filling turned lumpy. What happened?

Likely added starch to hot liquid or didn’t whisk continuously.

Next time, whisk all cold ingredients together first, then heat and whisk. You can salvage lumps by blending the hot filling with an immersion blender until smooth.

Can I double the recipe?

Yes. Use a 9×13-inch pan, add 3–5 minutes to both the crust par-bake and final bake, and ensure the filling reaches that pudding-thick stage on the stove.

Do these taste like coconut?

With refined coconut oil and plenty of lemon, the coconut note is minimal.

If you’re coconut-averse, opt for vegan butter in the crust and use a neutral vegan yogurt in the filling per the note above.

How do I get sharp, clean slices?

Chill fully, wipe the knife between cuts, and use a long, sharp chef’s knife. For extra precision, freeze for 20 minutes before slicing. Pro-level edges, zero drama.
