03 - Mix in egg, vanilla extract, lemon zest, and lemon juice until fully incorporated and smooth.
04 - Gradually blend in dry ingredients until just combined. Avoid overmixing to maintain tender texture.

09 - Place filled cookies on prepared baking sheets, leaving about 2 inches of space between each to allow for spreading.
