These Lemon Sugar Cookie Bars are an easy bar cookie with an intense lemon frosting recipe. They are perfectly chewy, sweet, and tart!

This easy bar recipe is quickly going to become a family favorite.  It’s hard to find the perfect sugar cookie.  I tried a dozen or so and then realized I’d go back to my favorite recipe and just modify it a little.  It is just a basic chocolate chip cookie recipe, I just use all white sugar instead of using white and brown.  Slather some frosting on that baby and you have yourself a dense, chewy, and buttery cookie!

The flavor is perfectly intense with this lemon frosting recipe.  It’s basically a buttercream frosting recipe except instead of the milk you add lemon just along with some lemon zest and lemon essential oil if you have it on hand.

Tips for making Easy Lemon Cookie Bars with Lemon Frosting:

• Make sure you have you butter at room temperature for your cookies and your frosting.
• You can bake these in a 9 by 13″ pan if you like thicker cookie bars or you can bake it on a bigger cookie sheet 12 by 17′ (We made them in both sizes.  The flavors are equally delicious thick and thin but we all liked the thinner cookies a little more.
• These are amazing frozen!

For the Lemon Buttercream Frosting
