Grandma’s Lemon Sugar Cookie Bars Recipe

Thanks for Sharing!

I love these Lemon Sugar Cookie Bars! 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!

Lemon Sugar Cookie Bars

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.

What You’ll Need

  • flour
  • baking soda
  • cream of tartar
  • salt
  • powdered sugar
  • oil
  • butter
  • eggs
  • vanilla
  • fresh lemon juice

Making Lemon Sugar Cookie Bars

Start by combining your dry ingredients in a bowl. Take your all purpose flour, baking soda, cream of tartar, and salt and whisk them together until smooth.

In my mixer bowl, I beat the butter, oil, and sugar. Scrape the sides down with a spatula and beat again until smooth. Then add the eggs one at a time, mixing them between each adding.

Add the vanilla extract and lemon juice to the mixer bowl and mix until combined.

Put the mixer on low speed, and gradually add the dry ingredients to the mixer bowl. Mix until all the powder if combined with the creamy butter mixture and it’s now smooth.

Spread the sugar cookie dough into a prepared pan. I spray my pan with nonstick spray, but you could use parchment paper instead if you prefer.

Once your bar cookie is baked and cool it’s time to add the lemon glaze! Whisk together the those ingredients and then I drizzle it on top in a zig zag pattern. If you prefer you could use an offset spatula and spread the glaze over the top evenly.

  3. Thank you. I refer to your recipes frequently because I can count on everything being so tasty. I bake for my church so I get lots of good feedback.

  4. 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?
