Preheat Oven to 350℉.
Line baking sheet with parchment paper.
In a medium mixing bowl combine flour, baking powder, baking soda and salt. Set aside.
Cream the butter and sugar together with electric mixer in a clean, large mixing bowl. Butter and sugar will combine to become light and fluffy. About 3 minutes.
Scrape bowl down, and beat in the egg, lemon zest, lemon juice, lemon extract, vanilla extract, poppy seeds and food coloring, if using.
With the mixer on low, slowly combine the flour mixture, scraping bowl down until well combined.
Scoop cookie dough into 1½ tbsp portions onto a baking sheet, keeping 2 inches space between each portion. Sprinkle with extra poppy seeds if desired.
Bake 10-12 minutes, or until edges just begin to brown.
Remove from oven and allow to cool on cookie sheet for 5 minutes before transferring to a cooling rack. Enjoy!
