Ingredients

  • 2 cups (4 sticks) butter softened
  • 2 cups powdered sugar divided
  • cups all-purpose flour
  • 1/2 cup cornstarch
  • 2 Tbsp fresh lime zest
  • 1/4 cup key lime juice
  • 1 tsp vanilla extract

Instructions

  • Preheat oven to 350 degrees F. Line 2 baking sheets with silicone liners or spray lightly with cooking spray. Set aside.
  • In the bowl of a stand mixer, beat together the butter and ONE (1) cup of the powdered sugar until creamy, about 2 minutes. Add in the key lime juice, the zest and vanilla and beat to combine. Lastly, add in the flour and cornstarch until a thick dough has formed.
  • Roll Tablespoon-sized balls of dough and place them 1" apart from one another onto the prepared baking sheets. Gently press them down with a sugared glass.
  • Bake for approx. 9-11 minutes, rotating pans halfway through baking time, until golden brown and set. Cool completely on the baking sheets. Remove to a wire rack and one by one, gently coat in the remaining powdered sugar. Serve!
