1eachLemon zested and juicedapprox. 3 tablespoons of juice
Pour the flour into a bowl and zest the lemon into the flour. Stir the zest and flour together until the zest is evenly distributed.
Pour the lemon juice and maple syrup into a small bowl. Give it a quick stir.
Pour the maple syrup mixture into the flour mixture. Stir all the ingredients together until well combined.
Preheat the oven to 350°F
Line the baking sheet with parchment paper, or lightly grease the surface of the baking sheet with oil or butter.
Scoop 1 tablespoon of dough and roll it between your hands into a ball. Place the ball on the baking sheet and use two or three fingers to flatten it just slightly, about ½ to ¾ inch thick. Repeat with the remaining dough. (The thicker the cookie, the longer it'll have to bake.)
Place in the oven and bake for 20 minutes, longer for a firmer cookie. The color will not change, so be sure to set a timer.
