Almond Flour Crust Gluten Free Lemon Bars

Jump to Recipe Print Recipe

A Nutty Crust Worth Celebrating

I first tried an almond flour crust when I ran out of gluten free blend, and the toasty, buttery flavor surprised me so much that I never went back.

Learn more about DanyRecipes and why I love happy kitchen accidents. These gluten free lemon bars pair a tender almond crust with a bright, silky lemon custard.

Why the Almond Flour Crust Wins

Almond flour brings natural richness and a delicate, cookie-like crumb, so you do not need a long list of specialty flours. The crust bakes up golden and fragrant, and it keeps its crisp edge under the creamy filling.

This lemon bars recipe fits an 8×8 pan and cuts into 16 squares, so it is a simple batch to share. It is one of my favorite lemon desserts for gluten free guests, and it sits near my chewy thumbprint lemon curd cookies on a dessert table, though you should check that those cookies suit your guests’ diets.

Almond Crust Ingredients

For the crust:

  • 2 cups blanched almond flour
  • 1/4 cup powdered sugar, plus extra for dusting
  • 1/4 teaspoon fine salt
  • 1/4 cup (4 tablespoons) unsalted butter, melted
  • 1 teaspoon vanilla extract

For the lemon filling:

  • 3/4 cup granulated sugar
  • 3 large eggs, at room temperature
  • 1/2 cup fresh lemon juice (about 3 lemons), strained
  • 1 tablespoon lemon zest, finely grated
  • 2 tablespoons almond flour
  • Pinch of salt

Easy Steps to Almond Crust Bars

STEP 1

Heat the oven to 350°F and line an 8×8 pan with parchment, leaving an overhang on two sides.

STEP 2

Stir the almond flour, powdered sugar, and salt, then mix in the melted butter and vanilla until a soft, sandy dough forms.

STEP 3

Press the dough firmly into the pan and bake for 12 to 15 minutes until golden around the edges.

STEP 4

Whisk the sugar, eggs, lemon juice, zest, almond flour, and salt until completely smooth.

STEP 5

Pour the filling over the warm crust and bake for 20 to 25 minutes until the center barely wobbles.

STEP 6

Cool on a rack, chill for at least 3 hours, then dust with powdered sugar and slice into 16 squares.

Serving Ideas and Easy Twists

  • Top with toasted sliced almonds for extra crunch.
  • Serve chilled with fresh raspberries or blueberries.
  • Pair with my crispy shortbread lemon curd cookies for a buttery crunch, keeping in mind those cookies contain gluten.
  • Add a drop of almond extract to the crust for a bakery style note.
  • Cut into small squares and wrap in parchment for gifting.

Ingredients
  

Almond Flour Crust
  • 2 cups blanched almond flour
  • 1/4 cup powdered sugar plus extra for dusting
  • 1/4 teaspoon fine salt
  • 1/4 cup unsalted butter melted; 4 tablespoons
  • 1 teaspoon vanilla extract
Lemon Custard Filling
  • 3/4 cup granulated sugar
  • 3 large eggs at room temperature
  • 1/2 cup fresh lemon juice strained; about 3 lemons
  • 1 tablespoon lemon zest finely grated
  • 2 tablespoons almond flour
  • 1 pinch salt

Equipment

  • 8×8-inch baking pan
  • Parchment paper
  • Mixing bowls
  • Whisk
  • Oven
  • Wire Cooling Rack

Method
 

  1. Preheat the oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
  2. In a bowl, stir together the blanched almond flour, powdered sugar, and fine salt. Add the melted butter and vanilla extract, mixing until a soft, sandy dough forms.
  3. Press the dough firmly and evenly into the prepared pan. Bake for 12 to 15 minutes, until golden around the edges.
  4. Whisk together the granulated sugar, room-temperature eggs, strained lemon juice, lemon zest, almond flour, and salt until completely smooth.
  5. Pour the lemon filling over the warm crust. Bake for 20 to 25 minutes, until the center barely wobbles.
  6. Cool the bars on a wire rack, then refrigerate for at least 3 hours until set. Dust with powdered sugar and slice into 16 squares.

Notes

Use blanched, finely ground almond flour for the smoothest, most tender crust. Press the dough firmly into the pan so it holds together when sliced. Let the crust cool for about 5 minutes before adding the filling. The center should still have a slight wobble when removed from the oven, as it will firm up while chilling. Refrigerate for at least 3 hours before slicing. For extra crunch, top with toasted sliced almonds. Serve chilled with fresh raspberries or blueberries. A small drop of almond extract can be added to the crust for a bakery-style flavor. Check that the powdered sugar and vanilla are labeled gluten free, and use clean tools and a clean knife when preparing these bars for someone with celiac disease. For a dairy-free variation, replace the butter with melted coconut oil or vegan butter. Store covered in the refrigerator for up to 4 days, with parchment between layers. Freeze undusted bars for up to 2 months.

Pro Tips

  • Use blanched, finely ground almond flour for the smoothest crust.
  • Press the dough firmly so it holds together when sliced.
  • Let the crust cool for 5 minutes before pouring in the filling.
  • Pull the pan when the center still wobbles, since it firms up as it chills.
  • Chill for a full 3 hours so the bars slice cleanly.
  • Check labels on powdered sugar and vanilla, and use a clean knife if baking for someone with celiac disease.

FAQs

Are these bars safe for celiac disease?
They are when every ingredient is labeled gluten free and your tools are free of regular flour. Always check the powdered sugar and vanilla labels.

Can I use almond meal instead of almond flour?
Almond meal works, but the crust will look speckled and feel a little coarser. Blanched almond flour gives the most tender, bakery style result.

How should I store the bars?
Cover and refrigerate for up to 4 days, with parchment between layers. Freeze undusted bars for up to 2 months.

Why is my crust crumbly?
It likely needed firmer pressing or a touch more butter. Press the dough tightly into the pan and let the bars chill fully before slicing.

Can I make these dairy free too?
Yes, swap the butter for melted coconut oil or vegan butter. The flavor stays rich and the crust stays tender.

Nutty, Golden, and Sweet

A simple swap can turn a good lemon bar into a new favorite. I hope this almond crust earns a spot in your recipe box. For more citrus treats, try my melt in your mouth lemon curd cookies, the 5 ingredient glazed lemon curd cookies, or the zesty drop lemon curd cookies.
