Preheat & prep: Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper or silicone mats. We like easy cleanup, don’t we?
Cream the butter & sugar: Beat butter and sugar together until light and fluffy. Think clouds, not butter soup.
Add eggs & flavor: Mix in eggs one at a time, then stir in lemon zest, lemon juice, and vanilla. You should start smelling sunshine now.
Mix dry ingredients: In a separate bowl, whisk together flour, baking soda, baking powder, and salt. Easy.
Combine wet & dry: Gradually add dry ingredients to the wet mixture. Don’t overmix—nobody likes tough cookies.
Add poppy seeds: Fold in poppy seeds gently, saving a few to sprinkle on top for aesthetics.
Scoop & shape: Drop tablespoons of dough onto prepared baking sheets, leaving 2 inches between cookies. They spread a bit, so don’t crowd them.
Bake: Bake 10–12 minutes, until edges are golden but centers are still soft. Set a timer—this is key.
Cool: Let cookies cool on the sheet for 5 minutes, then transfer to a wire rack. Try not to eat them all while warm… but no promises.
