Ingredients (~24 cookies)

For the Cookies

  • 3/4 cup (1 1/2 sticks) unsalted butter, room temperature
  • 3/4 cup granulated sugar
  • 3/4 teaspoon grated lemon zest
  • 1 large egg
  • 2 teaspoons dark rum
  • 1 2/3 cups all-purpose flour
  • 3/4 teaspoon baking powder
  • 1/4 teaspoon ground cardamom
  • 1/4 cup finely chopped almonds
  • 1/4 cup finely chopped candied lemon peel

For the Rum Glaze

  • 1/3 cup powdered sugar
  • 2 teaspoons dark rum

Make the Cookie Dough

In a small bowl, combine the granulated sugar and lemon zest. Rub them together with your fingers to release the oils from the zest.

In the bowl of a stand mixer, cream the butter and lemon sugar on medium speed until the mixture is light and fluffy; this should take ~1-2 minutes.

Add the egg and beat until combined, then mix in the rum.

Sift the flour, baking powder, and cardamom directly into the mixer bowl. Mix on low speed until the dough just comes together. Do not overmix.

Fold in the chopped almonds and candied lemon peel on low speed until they are evenly distributed.

Chill and Bake the Cookies

Divide the dough in half and shape each portion into a log about 2 inches in diameter. Wrap the logs tightly in parchment paper or plastic wrap.

Chill the dough in the refrigerator for at least 2 hours, or until firm.

When you’re ready to bake, preheat your oven to 350F and line a baking sheet with parchment paper.

Slice the chilled dough into 1/4-inch thick rounds and place them on the prepared baking sheet.

Bake for ~7-8 minutes. The cookies will not look fully baked, but they will set as they cool.

Let the cookies cool on the baking sheet for 2 minutes before moving them to a wire rack to cool completely.

Glaze the Cookies

In a small bowl, whisk together the powdered sugar and rum until a smooth glaze forms.

If it’s too thick, add a few more drops of rum. If it’s too thin, add more powdered sugar.

Drizzle the glaze over the cooled cookies. Let the glaze set before storing.
