Recipe Story

The Tradition of Lemon Bars

If you close your eyes and imagine the perfect lemon bar, your mind might go to your grandmother’s classic recipe or to a platter of your mom’s famous homemade bars. They’re light enough to follow a hearty home-cooked lunch, yet satisfying enough that the simple recipe feels decadent. They can be served casually out of the pan as a simple dessert or dressed up for a party, cut into triangles, dusted with powdered sugar and served on crystal.

What Makes Lemon Bars So Delicious?

With a tart, tangy lemon filling and a dense shortbread crust, one bite of this heavenly dessert is all it takes to have guests begging for the secret to this amazing lemon bars recipe. The secret, of course, is the addition of Duke’s Mayonnaise to the lemon bar’s crust. Using Duke’s in the crust ensures that the shortbread doesn’t flake or crumble apart. Duke’s also adds a lemony tang to the crust that complements the tart lemon filling.

The Best Year Round Treat

While this easy lemon bars recipe is great to make year round, whipping them up in the summer for a light afternoon treat goes great with a tall glass of cool milk. A light dusting of powdered sugar on top spruces up the appearance, and adds a hint of sweetness to complement the tangy filling flavor. Whether they are packed to have with lunch, paired with a cup of your favorite tea, or eaten at night alongside a scoop of ice cream, homemade lemon bars are the perfect dessert to satisfy your sweet tooth.
