Grandma’s Lemon Sugar Cookie Bars Recipe

Sharing is caring!

I love bar cookies!  I think it’s because they are so much quicker and easier than drop cookies… plus they are usually much thicker and chewier.  So I’ve got my Grandma’s Lemon Sugar Cookie Bars to share.  This bar cookie has a delightful, light lemon flavor with a lemony icing drizzled over the top…. so good!

My Grandma’s recipe is for drop cookies, so if you prefer you can make this cookie recipe that way, you’ll just need to shorten the cooking time to 10-12 minutes.

  1. Direction #3 for the bars says to add the “sugars”. I only see 1 cup confectioners sugar listed for the recipe in the bars. Should there be one other ingredient – such as granulated sugar?
