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.
