Growing up I didn’t love chocolate. I know… I’m ashamed to even admit that! My tastes have drastically changed since then, as you can tell by my pension for all things dark chocolate like my Decadent Dark Chocolate Brownies. However, the one dessert I could eat on a daily basis is a classic lemon bar. In fact, I would still dive head first into a pan of lemon bars for breakfast, snack, dessert, or midnight snack!

The criteria of my perfect lemon bar is as follows. It must have a delicious shortbread crust that has sweetness, flavor, and texture.

Let’s Bake!

The Crust

We begin with baking up a shortbread crust. The crust will take flour, salt, sugar, and a heaping tablespoon of fresh lemon zest.

Give this a mix before adding in two sticks of salted butter. The butter should be cold. You will cut the butter into small chunks then use a pastry cutter to blend this mixture together. This mixture will then get pressed into a buttered pan.

Bake this for about 20 minutes, until the crust bubbles up and edges begin to brown.

In the meantime, work on your filling.
