Lemon Thumbprint Cookies

Maggie Michalczyk, RDN
Gluten free lemon thumbprint cookies are easy to make with lemon curd and have a bright and tangy flavor in each bite! 
Prep Time 30 mins
Cook Time 8 hrs 10 mins
Servings 10 -12 cookies


  • for the cookies:
  • 1 egg
  • 1/2 cup creamy unsweetened peanut butter
  • 1/4 cup maple syrup
  • 1 tsp. vanilla extract
  • 1/3 cup blanched almond flour
  • 1/2 tsp. baking soda
  • 1/2 tsp. cinnamon
  • pinch of salt
  • for the lemon curd:
  • zest of 3 lemons
  • 1 1/2 cups sugar
  • 8 tbsp. unsalted butter room temperature
  • 4 eggs
  • 1/2 cup lemon juice about 3 lemons
  • 1/8 tsp. kosher salt


  • Start by making the lemon curd. Add sugar and lemon zest to a food processor or high-speed blender. Blend until combined (it will smell super citrusy!).
  • Cream the room temperature butter. Add the sugar and then add the eggs in one at a time mixing between each addition. Lastly add the lemon juice and salt and mix together until just combined. 
  • Transfer the lemon mixture to 2-quart saucepan and cook over low heat until thickened, stirring constantly. When you have your first bubble and the mixture is a lot thicker than what you started with, you'll know it's done.
  • Set aside to let cool.
  • In medium bowl combine egg, peanut butter, maple syrup, vanilla extract, almond flour, baking soda, cinnamon and salt. Mix until well combined.
  • Refrigerate for 10 minutes and preheat the oven to 350 degrees F. Line a baking sheet with parchment paper.
  • Use a cookie scoop to portion out the dough. Roll it into balls and gently flatten it out with your palm just a little. 
  • Bake for 10-12 minutes until the cookies are set.
  • Remove from oven and use the back of a 1/2 tbsp. to make "thumbprints" in the middle of each cookie. Once the cookies are cooled spoon a little lemon curd on top of each one. 
  • Store leftover lemon curd and cookies in the fridge for up to a week.
