Description

Zesty keto lemon bars offer a tangy, low-carb dessert that balances sweet and citrus notes perfectly. Silky lemon custard nestled on a buttery almond flour crust provides a delightful treat you’ll savor with each refreshing bite.


Ingredients

Scale

Main Ingredients:

  • 5 large eggs
  • 1 large egg yolk
  • ½ cup lemon juice

Baking Base Ingredients:

  • ¼ cup butter, softened (dairy-free if needed)
  • 1 ½ tablespoons coconut flour
  • ½ cup sugar-free powdered sugar

Instructions

  1. Prepare the oven by heating to 350°F (180°C) and line an 8×8-inch baking pan with parchment paper, ensuring complete coverage and slight overhang for easy removal.
  2. Create the crust by thoroughly blending almond flour, melted unsalted butter, and powdered sugar in a mixing bowl until a cohesive, crumbly texture develops.
  3. Firmly press the crust mixture into the bottom of the prepared pan, using the back of a spoon or fingers to create an even, compact layer that reaches all corners.
  4. Bake the crust for 15-17 minutes, watching for a golden-brown color that indicates proper toasting and flavor development.
  5. While the crust bakes, prepare the filling by whisking softened unsalted butter, fresh lemon juice, and powdered sugar until smooth and well-integrated.
  6. Incorporate whole eggs and an extra egg yolk into the mixture, then gently fold in coconut flour, stirring until the filling achieves a consistent, silky texture without lumps.
  7. Once the crust is golden, carefully pour the lemon filling over the hot base, ensuring an even distribution across the surface.
  8. Return the pan to the oven and bake for 20-22 minutes, looking for a slightly jiggly center that will set as it cools, indicating perfect doneness.
  9. Allow the lemon bars to cool completely at room temperature, then transfer to the refrigerator for a minimum of 2 hours to firm up and enhance flavor melding.
  10. Before serving, dust the chilled bars with an additional light layer of powdered sugar, creating an elegant, finished appearance.

Notes

  • Chilling matters: Let the bars rest in the refrigerator for at least 2 hours to achieve the perfect texture and help them set properly.
  • Low-carb swap: Powdered erythritol works brilliantly as a sugar substitute to keep these bars keto-friendly and deliciously sweet.
  • Lemon precision: Use fresh lemon juice for the brightest, most vibrant citrus flavor that elevates the entire dessert.
  • Baking tip: Watch the crust carefully while baking to prevent over-browning, as almond flour can burn quickly.
  • Storage secrets: These keto lemon bars can be stored in an airtight container in the refrigerator for up to 5 days, maintaining their incredible taste and texture.
  • Serving suggestion: Dust with a light sprinkle of powdered sugar substitute just before serving to create a stunning, bakery-style presentation.
