  • 1 cup unsalted butter melted
  • 1/2 cup granulated sugar
  • 1 tablespoon vanilla extract
  • 2 cups all-purpose flour spoon and leveled

  • Dump into the prepared pan and use your hands to firmly press the mixture into an even layer.
  • Bake for 25 minutes, or until the edges are lightly browned.

  • Into a large bowl, sift in the granulated sugar, flour, cream of tartar, and salt. Set aside.
  • In a medium sized bowl, whisk together the eggs, lemon juice, zest, and vanilla extract.
  • Combine the two mixtures and whisk until well combined.
  • Pour over the warm crust and bake for 35 minutes, or until the center is relatively set and only has a slight jiggle.
  • Remove bars from the oven and cool completely at room temperature (about 1-2 hours).
  • Transfer to the fridge and chill again until completely cold (about 1-2 additional hours).
  • Remove the bars from the pan, dust with powdered sugar (if desired), cut into squares, and enjoy cold!
