Add butter and sugar to your mixer and mix until creamed, 2-3 minutes
Add eggs, mix until combined
Using the stir setting on your mixer, stir in baking powder, salt, vanilla extract, lemon extract, lemon juice, and flour. Stir until all ingredients are well incorporated.
With lightly floured hands, form 1.5 inch balls (dough may be sticky!) and place on a baking sheet lined with parchment paper.
Using lightly floured fingers, press the cookies down to about 1/2 inch thickness, allowing room for three M&M's candies.
Place three M&M's candies on each cookie and press in slightly
Bake fore 10-12 minutes (ours were 12 minutes) - the edges will just barely begin to show a hint of brown on the bottom edge when they're ready.
Remove and cool on cookie sheet for 5 minutes or more before moving to cooling rack
Repeat until you've baked all of your cookies! We got 28 out of the batch, depending on how big or small you make your cookies, the number will vary.

Notes
These lemon drop cookies are easy to make. Flour your hands to prevent the dough from sticking to your fingers while you're making the dough balls.Also flour your hands when pressing the cookies down into discs.
