Recipe Ingredients

For the Cookies

• 2 cups Almond Flour
• 1/3 cup Granulated Erythritol
• 1/4 tsp Baking Soda
• Pinch of Salt
• 1 Large Egg
• 3 tbsp Unsalted Butter, melted
• 2 tbsp Fresh Lemon Juice
• 2 tsp Lemon Zest
• 1/2 tsp Vanilla Extract

For the Lemon Glaze

• 1/3 cup Powdered Erythritol
• 1 tbsp Fresh Lemon Juice
• 1/2 tsp Lemon Zest

How To Make

Step 1

Preheat your oven to 325°F (165°C). Line a large baking sheet with parchment paper.

Step 2

In a medium bowl, whisk together the almond flour, erythritol, baking soda, and salt.

Step 3

Add the egg, melted butter, lemon juice, lemon zest, and vanilla extract to the dry ingredients. Stir until a soft, slightly sticky dough forms. If the dough feels too soft, refrigerate it for 15 minutes.

Step 4

Scoop tablespoon-sized portions of dough and roll them into balls. Place them on the prepared baking sheet about 2 inches apart and gently flatten each one to about half an inch thick with your palm.

Step 5

Bake for 12 to 15 minutes, until the edges are just golden. The centers may look slightly soft but will firm up as they cool. Let the cookies cool on the baking sheet for 10 minutes, then transfer to a wire rack to cool completely.

Step 6

Make the glaze by whisking together the powdered erythritol and lemon juice until smooth. Stir in the lemon zest.

Step 7

Drizzle the glaze over the cooled cookies with a spoon or fork. Let the glaze set for about 10 minutes before serving.

Tips

Chill the Dough if It Feels Oily

Almond flour has a lot of natural fat, and when you add melted butter on top of that, the dough can feel greasy and too soft to shape. If that happens, pop it in the fridge for 15-20 minutes.

Cold dough is way easier to roll into balls and it holds its shape better in the oven. If you skip this step with soft dough, the cookies will spread too thin and the edges will get overly crispy.

Use Finely Ground Almond Flour

There’s a big difference between almond flour and almond meal. You want the super fine, blanched almond flour for these cookies. It’s made from skinless almonds and has a smooth, powdery texture.

Almond meal is coarser and has the skins ground in, which gives the cookies a gritty feel and a heavier texture. The fine stuff is what makes these cookies actually taste delicate and not dense.

Don’t Overbake Them

Pull the cookies out when the edges are just barely golden, even if the centers still look a little underdone. They’ll keep cooking on the hot baking sheet as they cool.

Almond flour cookies go from perfectly done to dry and crumbly really fast. At 325°F, start checking at the 12-minute mark. If the tops feel slightly soft to the touch but the edges have some color, they’re done.

Frequently Asked Questions

Can I use coconut flour instead of almond flour?

Coconut flour is not a simple swap here because it absorbs way more liquid than almond flour. If you try to use the same amount, your cookies will turn out dry and crumbly.

If coconut flour is all you have, you would need roughly 1/3 cup instead of 2 cups, and you would likely need to add an extra egg to hold everything together. That said, almond flour gives the best results for this recipe.
