  • 1/2 Teaspoon baking powder
  • 1/4 Teaspoon salt
  • 1 Cup (2 sticks) unsalted butter, room temperature
  • 3/4 Cups Imperial Sugar Extra Fine Granulated Sugar
  • 1 large egg
  • 2 Teaspoons vanilla extract
  • 1 Teaspoon fresh key lime zest

For the Icing

Directions

For the Cookies

Preheat oven to 375°F.

Line a baking sheet with parchment paper or a silicone baking mat.

Set aside.

In a medium bowl, whisk together flour, baking powder, and salt.

Set aside.

In a stand mixer, beat butter and sugar until light and fluffy.

Add egg, vanilla extract, and lime zest, mixing until combined.

Add flour mixture 1/2 cup at a time, mixing until completely combined.

Roll 1 tablespoon of dough into small circles and then press with hands (or with the bottom of a cup) into a disk shape.

Place on prepared baking sheet.

Bake for 8 minutes.

Cookies will not look browned or cooked, but they are!

Remove from oven and let cookies rest on baking sheet for 5 minutes.

Then transfer to a wire rack to cool completely.

For the Icing

To ice, in a small bowl, whisk together powdered sugar, lime juice, vanilla extract, milk, and lime zest until smooth.

Using a spoon, smooth icing onto the top of each cookie, sprinkle with crushed graham cracker and let set for 10 minutes, or until hardened.

Store leftovers in an airtight container.
