Lemon Bar Recipe

This old fashioned lemon bar recipe is a classic family favorite. The buttery crust is covered with a lemon filling that is both sweet and tangy. Dusted with powdered sugar before being served, this homemade dessert is the best!

This is one recipe that I really recommend using a glass baking dish for.
Use fresh squeezed lemon juice to really enhance the flavor this recipe.
