Step 1: Preheat the oven to 350°F (175°C) for even baking.
Step 2: Line a baking sheet with parchment paper to prevent sticking.
Step 3: In a medium bowl, whisk together almond flour, powdered sugar, lemon zest, salt, and baking soda.
Step 4: In a separate bowl, beat the butter until creamy, then add vanilla extract and lemon juice.
Step 5: Gradually mix the dry ingredients into the wet mixture until a soft dough forms.
Step 6: Roll the dough into small balls, about one inch in diameter.
Step 7: Bake the dough balls for 10-12 minutes, until edges are lightly golden.
Step 8: Cool on the baking sheet for a few minutes before transferring to a wire rack.
