Wholesome Ingredients for This Best Lemon Bars with Shortbread Crust

We love using nutrient-dense, whole-food ingredients in our recipes, and these lemon bars are no exception. Here’s why a few key ingredients shine:

• Fresh Lemon Juice: Opt for freshly squeezed lemons for maximum flavor and nutrition. Bottled lemon juice often lacks the vibrant tang and nutrients of fresh citrus.
• All-Purpose Flour: While traditional, you can swap this for a gluten-free flour blend for those avoiding gluten. Almond flour also works as a nutty, low-carb alternative.
• Unsalted Butter: Provides richness to the crust. You can substitute with ghee for a lactose-free option or coconut oil if you’re dairy-free.
• Granulated Sugar: Sugar lends structure to the lemon curd filling. To reduce the glycemic impact, swap for coconut sugar or a keto-friendly sweetener like erythritol.

• 1/2 cup (100g) granulated sugar
• 2 teaspoons pure vanilla extract
• 1/2 teaspoon salt
• 2 cups + 2 tablespoons (265g) all-purpose flour, spooned and leveled

How to Make Best Lemon Bars with Shortbread Crust

1. Preheat the oven to 325°F (163°C). Line a 9×13-inch glass baking pan with parchment paper, leaving an overhang for easy lifting.
2. Make the crust: Mix melted butter, sugar, vanilla extract, and salt in a medium bowl. Stir in flour until a thick dough forms. Press evenly into the prepared pan. Bake for 20-22 minutes until edges are lightly golden. Poke holes in the crust with a fork to help the filling stick.
3. Prepare the filling: Sift sugar and flour into a large bowl. Whisk in eggs, followed by fresh lemon juice and zest. Pour filling over the warm crust.
4. Bake the bars for 22-26 minutes, or until the center is set and doesn’t jiggle when tapped. Allow the pan to cool completely.
5. Chill the bars in the refrigerator for 2-3 hours. Use parchment overhang to lift and dust with confectioners’ sugar before cutting into squares.
