Diabetic-Friendly Lemon Thumbprint Cookies

Ready in: 30 minutes

Servings: 18–20 cookies
Difficulty: Easy

 Ingredients:

For the cookies:

  • 1 ½ cups almond flour (or 1 cup almond flour + ½ cup coconut flour for firmer cookies)

  • 3 tbsp granulated erythritol (or monk fruit sweetener)

  • ¼ tsp baking powder

  • ¼ tsp salt

  • 1 large egg

  • 2 tbsp unsalted butter, melted (or coconut oil)

  • 1 tsp vanilla extract

  • Zest of 1 lemon

For the lemon filling:

  • 2 tbsp fresh lemon juice

  • 1 tsp lemon zest

  • 1 large egg yolk

  • 1–2 tbsp powdered erythritol

  • 1 tbsp butter

(You can also use store-bought sugar-free lemon curd if you prefer.)

 Instructions:

1. Preheat oven

Preheat to 350°F (175°C). Line a baking sheet with parchment paper.

2. Make the dough

In a medium bowl, mix almond flour, erythritol, baking powder, and salt.
Add the egg, melted butter, vanilla, and lemon zest. Stir until a soft dough forms.

3. Form cookies

Scoop 1 tbsp portions of dough, roll into balls, and place on the baking sheet.
Use your thumb or the back of a spoon to make a small indentation in the center of each cookie.

4. Bake

Bake for 10–12 minutes, until edges turn golden. Let cool completely.

5. Prepare lemon curd filling

In a small saucepan over low heat, whisk lemon juice, zest, egg yolk, erythritol, and butter until thickened (about 4–5 minutes). Cool slightly.

6. Fill cookies

Once cookies are cool, spoon about ½ teaspoon of lemon curd into each indentation.

7. Dust and serve

Optional: Dust with powdered erythritol for a pretty finish.
