Ingredients

Scale
  • 1 ½ cups almond flour (finely ground)
  • ⅓ cup powdered erythritol (or preferred keto-friendly sweetener)
  • ¼ teaspoon sea salt
  • 6 tablespoons unsalted butter, melted
  • 1 teaspoon vanilla extract (optional)
  • 16 ounces cream cheese, softened
  • ⅔ cup powdered erythritol
  • 3 large eggs, room temperature
  • ½ cup freshly squeezed key lime juice (or regular lime juice)
  • 1 tablespoon key lime zest
  • ½ teaspoon pure vanilla extract
  • Pinch of salt

Instructions

  1. Preheat your oven to 350°F (175°C). Line an 8×8 inch pan with parchment paper, leaving some overhang for easy removal.
  2. In a large bowl, combine almond flour, powdered erythritol, and sea salt. Stir to mix well.
  3. Pour in melted butter and vanilla extract. Mix with a spatula until the mixture resembles wet sand.
  4. Press the crust firmly and evenly into the bottom of the prepared pan. Bake for 12-15 minutes until edges are golden and crust smells toasty.
  5. While the crust bakes, beat softened cream cheese and powdered erythritol in a medium bowl until smooth and creamy.
  6. Add eggs one at a time, mixing well after each addition.
  7. Stir in lime juice, lime zest, vanilla extract, and a pinch of salt until the mixture is pourable but thick.
  8. Pour the filling over the warm almond crust and spread evenly.
  9. Bake for 18-22 minutes until bars are slightly set but still jiggle in the center.
  10. Cool bars at room temperature for 30 minutes, then refrigerate for at least 3 hours or overnight.
  11. Use parchment overhang to lift bars from pan and slice into 12 squares.

Notes

Use room temperature cream cheese and eggs for smooth texture. Press crust firmly to avoid crumbling. Avoid overbaking the filling; it should jiggle slightly when done. Chill bars for at least 3 hours for best texture. For a dairy-free version, substitute cream cheese with coconut-based alternative and butter with coconut oil, and use a flax egg instead of eggs.
