How To Make Lemon Cookie Bars

Prep – Before you get started, you’ll want to preheat your oven to 375 degrees F.   You’ll also want to line your 9×13 baking pan with either parchment paper to keep things from sticking and destroying your culinary masterpiece.

Wet Ingredients – Start by beating the butter and sugar together until it has a light and fluffy texture.  Next, add in the lemon zest and continue to mix it until it’s fragrant.  After that has mixed in, add the remaining wet ingredients to the mixer and keep stirring until it has a smooth texture.

Dough – After the wet ingredients have been fully blended together, it’s time to add the dry ingredients.  Add the flour, baking powder and salt to the mixer and let it run until it has formed a crumbly dough.

Cook – Pour the dough into the baking pan and then press it down until you have formed an even layer.  Before placing it in the oven, you’ll want to pierce the dough with a fork about a few inches to keep the dough from bubbling in the oven.  Bake the lemon bars for about 17-20 minutes.  The edges should be golden brown when they’re done.  Let them cool completely before adding the frosting.

Frosting – To make the buttercream frosting, start by beating the powdered sugar and butter together until it’s creamy.  Then add in the remaining ingredients and mix it until smooth.  Add in the food coloring and then continue beating the frosting until it’s fluffy.  Once done, spread it on the lemon cookie bars and enjoy!
